Refractory ramming mass (refractory taphole mass) is a kind of Refractory used for lining of blast furnace tapping groove. It is mainly used to protect the blast furnace out of the ditch from high-temperature hot metal and slag erosion and erosion, and has excellent high-temperature resistance and wear resistance. The ramming material for the iron discharge ditch is usually composed of corundum, silicon carbide and carbonaceous material, which has the ability of resisting hot metal and molten slag erosion and scouring, reburning line change small, strong resistance to a variety of oxidation characteristics. The construction of the ramming material for the iron ditch is convenient, easy to dismantle and repair, does not produce harmful gas, and is beneficial to environmental protection.
The high-alumina refractory bricks sold by Yuying refractory manufacturers are commonly used refractory bricks with high thermal stability and refractoriness above 1770°C. It has good slag resistance and is used for the lining of steelmaking electric furnaces, glass melting furnaces, cement rotary furnaces, etc.
