What are the requirements for kaolin as refractory material, such as how much aluminum is needed?
Kaolin as refractory material actually plays two roles, one is to improve refractoriness, and two is to improve the body plasticity of refractory material
Kaolin aluminum content does not have to be too high, more than 38% on the line, viscosity is to consider, the best sticky point, so as not to add extra bentonite. Fire resistance of more than 1400 degrees enough
The higher the amount of aluminum, of course, but the refractories do not use only kaolin to increase the aluminum content, all use bauxite, coke, precious stones and other aluminum containing higher raw materials to do the skeleton
