Fused cast skid rail Zircon Corundum Mullite bricks
Fused cast skid rail Zircon Corundum Mullite bricks are made of raw materials such as high-grade mullite grog and Australia imported zircon sand, which are melted and casted in high temperature electric furnace. It is mainly used in areas that require high abrasion and temperature resistance, such as gliding rail bricks in steel pusher metallurgical furnaces, the tapping platform (tapping spout) for tapping platform (tapping spout) style walking beam furnaces, and also as the interior for destructors.
Descriptions
Fused cast skid rail zircon corundum mullite bricks produced at HongTai are of various types including steel discharging platform brick,skid rail block and iron discharging tank blocks.This series block features great strength,good wear and fused slag corrosion resistance as well as long service life(one to two years). Compared to fused cast AZS and zircon mullite bricks,fused cast skid rail block can reduce maintenance cost and increase furnace efficiency.
Specification and application
1.Mainly made from Al2O3 and ZrO2, it has excellent performance in fire resistance degree, softening deformation temperature,flexural strength,curving temperature,stability and fused slag corrosion,etc. Widely used for steel reheating stove skid rail and steel discharging platform,slot and other consumable parts in industrial furnaces.
2.High abrasion and temperature resistance, ideal for large billet,large friction parts and steel discharging parts in reheating stoves.
3. Gliding rail bricks in steel pusher metallurgical furnaces, the tapping platform (tapping spout) style walking beam furnaces, and also as the interior for incinerators.
