Ⅰ. Understand the graphite rod

Graphite rod is a non-metallic product. As a necessary cutting consumable before welding in the carbon arc gouging cutting process, it is made of carbon, graphite and appropriate binder, and is formed by extrusion, baked and rotated at 2200 °C. It is made of a layer of copper plated after the section, which is resistant to high temperature, has good electrical conductivity, and is not easy to break. It is suitable for cutting metals into shapes that meet the requirements. high pure graphite rod are often used in the electric heating body of high temperature vacuum furnaces, the maximum operating temperature can reach 3000 ℃, and it is easy to be oxidized at high temperature. Except for vacuum, it can only be used in neutral atmosphere or reducing atmosphere.

Ⅱ. Advantages of high-purity graphite rods in the electronics industry

High purity graphite rod and high-density graphite products are prized for their thermal stability, electrical and thermal conductivity, thermal expansion, flexural strength, tensile strength, and high electrical resistance capacity. High-density graphite can replace ordinary graphite in many occasions such as refractory materials, nuclear reactors, and batteries. This is an extremely promising research area with many possibilities for future applications. Space reentry vehicles, missiles, and modern aircraft can take advantage of the strength and other properties of VHD with proper design and application. There are many different kinds of graphite rods for sale. And high-purity graphite rods are also widely used as electrode materials in electrical discharge machining (EDM), and compared to copper, graphite can significantly reduce production costs while providing equal or better product quality.

The high-purity graphite rod is an anisotropic material. It is made into a gate and has high axial thermal conductivity, which is beneficial to reduce the gate temperature. At the same time, the thermal expansion coefficient of graphite is small, which is not easy to deform at high temperature, and is not prone to frequent thermal short-circuit damage to the molybdenum grid. The distance between electrodes can be reduced, the working frequency can be increased, and the electrode size of the tube can be made more accurate, so as to improve the reliability and life of the tube. Offers a wide range of product grades for electronics throughout the entire process chain for the manufacture of forming and forging tools. Their capabilities extend from high roughing rates to ultra-fine finishing.

Ⅲ. Advantages of high-purity graphite rod used for gate

Besides graphite rods for electrolysis, high-purity graphite rods are used for gates and have the following advantages:
1. Withstand high power: molybdenum grid can withstand power of 7 to 14W/㎠, and high-purity graphite rod can withstand power of 60W/㎠, which is of great help in reducing tube volume power consumption, reducing weight and increasing power.

2. Low secondary electron emission coefficient: Pyrolytic graphite has low electron emission coefficient, so there is no need to spray precious metal surface.

Vacuum furnace graphite products are increasingly widely used. They are not only used to manufacture heating elements and heat insulation screens of vacuum furnaces but also used to manufacture structural parts such as bracket, material tray, guide rail, bolt, bearing, fan blade, and so on. The application of graphite crucible induction furnace greatly simplifies the design and manufacture of vacuum furnaces, reduces the consumption of metals such as tungsten, molybdenum, tantalum, and stainless steel, reduces the cost, improves the performance of graphite vacuum furnace, and expands the scope of use of vacuum furnace.

Characteristics of Vacuum Furnace Graphite
Graphite has good chemical stability, after special processing of graphite, corrosion resistance, good thermal conductivity, low permeability characteristics, is widely used in the production of the heat exchanger, reaction tank, condensing device, combustion tower, absorber, cooler, heater, filter, pump equipment.

How to Choose Vacuum Furnace Graphite
The choice of heater material mainly depends on the operating temperature. For low operating temperatures, such as vacuum tempering, cheaper ni-cr alloys can do the job. Molybdenum and graphite are the most popular materials for heat treatment such as quenching furnaces and brazing furnaces that require high temperatures. For many years, molybdenum was almost exclusively used in vacuum heat treatment and brazing furnaces, and there was a common misconception that materials discharged from graphite would react with certain materials and contaminate the vacuum furnace graphite.

Potential of Vacuum Furnace Graphite
Early graphite heaters were limited to simple shapes, and the connections and electrical properties between graphite components were not very stable. With the improvement of graphite material properties and processing technology, more and more heating graphite rods have been applied to heat treatment and brazing furnaces, and the number has exceeded molybdenum heaters. The main advantages of graphite heaters are their lightweight design, rich shape, durability, and ease of maintenance.

THE ADVANTAGES AND FUNCTIONS OF GRAPHITE PRODUCTS(2023年)

whgraphitesupplier — 2023-09-19T18:32:06+0900

https://www.whgraphitesupplier.com/the-advantages-and-functions-of-graphite-products.html

In recent years, graphite rods, graphite blocks, carbon graphite molds, graphite rounds, graphite crucible, graphite plates, graphite powder, and other graphite products have been used more and more widely, thanks to the superior functions of graphite.

Superior features of graphite products
Next, let's take a look at the superior features of the high-purity graphite product. The interstitial structure of carbon makes carbon have good adsorption, so carbon is often used as an adsorption material to absorb moisture, odors, toxic substances, etc. We have done experiments. The graphite pan used for barbecue looks very clean, but when it is heated on the induction cooker, the graphite products will gradually see out the grease and harmful substances adsorbed during the previous barbecue, but don't worry, use clean Wipe clean the paper napkins before use.

Superior advantages of graphite products
Graphite products have good thermal conductivity, fast heat transfer, uniform heating, and fuel-saving. Baking pans made of graphite heat up quickly, and the cooked food is evenly heated, cooked from the inside to the outside, and the healing time is short, not only the taste is pure, but also the nutrients of the original food can be locked. Graphite products have chemical stability and corrosion resistance. Graphite has good chemical stability at room temperature and is not corroded by any strong acids, strong alkalis, and organic solvents. Therefore, even if the graphite products are used for a long time, there is very little loss, and they only need to be wiped clean as new. Graphite products have strong anti-oxidation and reduction effects. Products, especially graphite mattresses, can generate negative oxygen ions after heating, activate surrounding objects, maintain human health, effectively prevent aging, and make the skin full of luster and elasticity.

GRAPHITE ROD IN THE VACUUM FURNACE ATTENTION TO THE 4 MAJOR MATTERS(2023年)

whgraphitesupplier — 2023-09-19T18:31:35+0900

https://www.whgraphitesupplier.com/graphite-rod-in-vacuum-furnace-attention-to-4-major-matters.html

Heating graphite rods are often used in high-temperature vacuum furnaces, where they serve as an electric heater that facilitates the easy oxidation of products at high temperatures, making it simpler to produce the right product. Why are heating graphite rods so popular in the market? Mainly because of its high-cost performance.

High Performance of Heating Graphite Rods
The thermal conductivity and electrical conductivity of heating graphite rods are very high, for example, the thermal conductivity is different from the general metal materials, it is greater than iron, lead, steel, and other such metal materials, and will increase with the temperature, the thermal conductivity decreases. The conductivity of carbon graphite rod is 4 times higher than stainless steel and 2 times higher than carbon steel.

Heating Graphite Rods Characteristics
Good Uniformity
When we appear the vacuum furnace as an electric heater, we need to choose the heating part of the red heat uniformity, because it will affect the temperature distribution and service life of the furnace. If the heating graphite rods are used with poor red heat uniformity, it will cause the graphite rods to fracture.

The Surface Temperature
Due to the nature of the graphite rod itself, the higher the temperature, the shorter the service life will be. It can be seen that if the surface temperature of heating graphite rods exceeds a certain temperature, the oxidation rate will increase and the lifetime will be shortened. Therefore, we recommend that you do not make its surface temperature too high when you use it.

Leave Enough Voltage Adjustment Margin
When the heating graphite rods are heated in the air, their surface will form a kind of antioxidant protection film that we often say. Then, we need to make sure the temperature in the vacuum furnace graphite is stable when we use it intermittently so that it is beneficial for us to use the new graphite rod when the resistance of the graphite rod will increase at a lower voltage.

The Late Voltage
When using multiple graphite rods, the voltage required at the later stage will be higher than the voltage of the new rod. Therefore, we need to pay attention to the later voltage, and according to the regulation or wiring method to adjust, generally speaking, the later voltage limit will also have a certain calculated value.

GRAPHITE MOULD FOR CASTING(2023年)

whgraphitesupplier — 2023-09-19T18:31:06+0900

https://www.whgraphitesupplier.com/graphite-molds-for-casting.html

Artificial graphite is considered to be the most suitable material for the continuous or semi-continuous casting of non-ferrous metals. Production practice has proved that using graphite mould continuous casting industry, because of its good performance of thermal conductivity, thermal conductivity performance determines the speed of solidification of the metal or alloy), mold good self-lubricating performance factors, not only make the casting speed, and due to the size of the graphite blocks for casting precision, smooth surface, uniform crystal structure, can be directly for the next working procedure of processing. This not only greatly improves the rate of finished products, reduces the loss of waste, but also greatly improves the quality of products.

Graphite Mould for Casting Benefits
The coefficient of thermal expansion is an important factor to determine the use of graphite as die material. Molds are media with very heterogeneous temperatures, hot from the inside due to the molten material and cold from the outside due to the cooling process applied to them. The low thermal expansion coefficient exhibited by graphite enables the die to function without deformation or cracking. Another very important factor is self-lubrication. Graphite is a solid lubricant that creates low friction between the mold and the casting material. The graphite can then be smoothly extracted from the casting.

Graphite mold casting aluminum Factors
There are many factors that determine the life of continuous casting graphite dies. The composition of casting material, to casting temperature, to cooling rate, will affect the life of graphite mold. The specific graphite grade used is also determined by a number of factors. The main factor is what kind of material technology is to be used in the graphite mould casting. For example, for gray cast iron or high-nickel alloys, wear-resistant graphite is required, while for brass, relatively dense graphite with sufficient porosity to allow zinc to evaporate would be a better choice.

POPULAR CARBON GRAPHITE PRODUCTS

GRAPHITE CRUCIBLE FOR INDUCTION FURNACES
Graphite crucible of induction furnace is easy to be oxidized in high temperature and strong oxidation atmosphere. Therefore, strong oxidation atmosphere should be avoided when providing different pyrogens, otherwise it will reduce the use function. Crucible should be checked before the furnace cracks, gaps and other defects.

QUARTZ GRAPHITE CRUCIBLE
Graphite crucible works best with a quartz jacket because graphite oxidizes. High purity graphite crucible is good or bad with its material and density. Good graphite crucible doesn't oxidizes easily, so that the production loss is low. Bad graphite oxidation is not uniform and will eat the material, resulting in high loss. Graphite crucible oxidation is easy to thin and even rupture through the use of pure graphite crucible covered with quartz crucible jacket, which can provide protection.

EDM GRAPHITE(2023年)

whgraphitesupplier — 2023-09-19T18:30:37+0900

https://www.whgraphitesupplier.com/edm-graphite.html

What Is EDM Graphite?
EDM graphite, also known as graphite for EDM machining, is a new material. Nowadays, EDM graphite products like EDM graphite rod and blocks become more and more widely used in the precision mold processing industry. EDM is the principle of removing layers of materials on the surface of the workpiece by using the transient high temperature generated when the spark between the electrode and the workpiece is energized. EDM is suitable for machining conductive workpieces with high hardness. The numerical control EDM forming machine is the best example of EDM.

How EDM Graphite Works?
At present, more than 90% of the electrode materials used in mold processing plants in developed European countries are EDM graphite materials. Copper, once the dominant electrode material, has almost lost its advantage over graphite. Why is that? Because EDM graphite electrode materials for discharge have a great advantage, because the spark oil also contains C atoms, in electro-discharge machining, the C atoms are in high temperature making the spark oil decomposition, thus the surface of the graphite rod electrodes in EDM form a protective film and compensate the loss of graphite electrode. As a consequence, electrode loss of EDM graphite rods and blocks is small, which leads to longer service life.

EDM Graphite Electrode Importance
The manufacturing industry is developing in the direction of high-end and intelligent manufacturing is greatly promoted. Thus, in the field of precision mold manufacturing, the requirement for processing the discharge material used is higher and higher, so the position of EDM graphite in the precision mold processing is higher and higher, Therefore, the screening of EDM materials has been highly concerned by the industry, and the high-quality EDM graphite produced by WH graphite, one of the leading graphite products manufacturers in China, is increasingly selected by high-end mold manufacturers.
