Refractory material production process introduced

According to the degree of compactness and shape of the product, there are sintering method, casting method and melt injection method. Sintering method is the raw materials of raw materials pre-baked clinker, broken and sieved, and then by a certain ratio and raw materials mixed, through the molding, drying and firing. Casting method is the raw materials through the ingredients mixing and fine grinding process, in the high temperature melting, direct casting, cooling crystallization, annealing products. Their body is... [Lire la suite]

Environmental significance of composite refractory materials

The composite refractory material has been developed rapidly in recent years because of its high strength and low density, which is a kind of popular material instead of steel production. In particular, the technology of glass fiber reinforced composite refractory has been mature and In the automotive industry has been a lot of applications. However, the glass fiber is harmful to the human body and is easy to be bonded after melting, resulting in difficulty in recycling. The natural fiber is recyclable, biodegradable, available,...
