Fire Resistant Asc Alumina Sic Carbon Refractory ASC Bricks for Torpedo
Product Introduction:
Aluminum silicon carbide carbon brick is also called ASC brick. It uses fused corundum (or sintered corundum, special grade bauxite clinker), graphite and silicon carbide with fixed carbon above 90%-95% as the main raw materials, combined with resin.After being mixed by a mixer, it is formed by press molding. After drying, it is processed at a low temperature of 210°C.
Application:
It is mainly used in the iron and steel industry, such as torpedo tanks, hot metal tanks, shakers, etc.
Torpedo tanks are not only subject to corrosion by ordinary molten iron, but also severely corroded by metallurgical auxiliary materials. For example, the desulfurizer is CaO-CaF2-CaC2, the desilication agent is usually fish scales or lime, and the dephosphorization agent is FeO-CaO-CaF2 or Na2CO3, which have very serious melting corrosion and oxidation effects on high alumina series refractories.
