Refractory production process introduction, glass technology

According to the degree of compactness and shape of different products, there are sintering, casting and melt casting method.



Sintering method is to pre-burn the department of raw materials into clinker, crushing and screening, and then press a certain ratio and raw materials mixed by forming, drying and firing.

Casting method is the raw materials through mixing ingredients and fine grinding and other processes, melting at high temperatures, direct casting, cooling and crystallization, annealing products.

Their compact body, high mechanical strength, high temperature structural strength, slag resistance is good, the scope of use continues to expand. Melt blowing method is to melt the ingredients, the high pressure air or superheated steam injection, so that the dispersion into fibers or hollow ball method.

Products are mainly used as light refractory, heat insulation materials, but also made of powder or granular amorphous refractories, temporary use of tar, asphalt, cement, phosphate, sulfate or chloride binder bonding, without Forming and sintering directly.
