Non-stick Aluminium Castable

1.These series non-stick aluminium castable is a new material with low cement content and ultrafine powder combined with high purity mullite, andalusite and sillimanite as the base material.
2.These series non-stick aluminium castable has high bulk densit,high strength,good thermal shock stability,by adding additives to improve the corrosion resistance,erosion resistance,non-stick aluminum and slag function of castable,extend the life of the refractory lining.

Applications

Melting aluminium furnace roof,furnace wall,furnace bottom,furnace door,discharge outlet,aluminum ladle,flow groove,degassing box,holding furnaces

 

Feature

Good integrality,high strength,anti-corrosion,anti-slipping,anti-osmotic,Good thermal stability,Non-stick aluminum,Non-stick slag

  Feature:

  1.Non-stick aluminum
  2.No slag produced
  3.No aluminum ash emission
  4.No erosion

  Application:

  Non-stick aluminum castable can significantly improve the service life of the molten aluminum alloy furnace,in   the aluminum smelting process does   not produce aluminum ash,no corundum tumor,to prevent metal  aluminum solution in the refractory elements of the reaction,so as to avoid impurities   into the aluminum alloy affect the quality of aluminum alloy.Reduce the adhesion rate of aluminum liquid, improve the anti-seepage ability.
