General Description of Grain Refiner
Grain refiners in aluminum alloy castings can optimize the form and grain distribution of eutectic silicon. The material synthetic mechanical properties, strength and ductility are enhanced. At same time, it can minimize hot cracking tendency. Control the structure and dispersion of individual crystals in metals improved mechanical strength and soundness of the casting.

Advantage of Grain Refiner
Improve the strength and toughness of aluminum alloy.
Eliminate columnar grains and feathery grains.
Improve the intrinsic quality of aluminum products by reducing the internal shrinkage cavities, porosity, hot cracking and segregation.
Increase more flexibility during the plastic deformation of the subsequent processing in the casting by improving its ductility
Reduce surface defects of aluminum product by improving its ductility.
Improve calendaring rate and productivity on the premise of ensuring the quality of products.
Increase the using time of the calendaring molds and auxiliary equipment on the premise of ensuring the quality of products.
Make the surface of aluminum more beautiful by improving the surface treatment of aluminum product

Application of Grain Refiner
Hardeners: Used for enhancing physical and mechanical properties of metal alloys.
Grain refiner for aluminium: Used for controlling the dispersion of individual crystals in metals to produce a finer and more uniform grain structure
Modifiers & Special Alloys: Typically used to increase strength, ductility and machinability.

Using method of Grain Refiner
Baking before using
Operation temperature 680-720 ℃
Joint quantity: Self controlled by calculation and test according to actual condition.
Joint method: After digging up the drum. Plunge the additives slightly to the Al liquid and mix evenly. Keep immersing for 5-10 minutes.

Storage of Grain Refiner
If stored in low humidity environment in the original packing, product can be preserved for a long time.
