EAF tap-hole filler is developed with magnesite, forsterite and silica as the main materials according to different requirements, and shows the features of easy installation, good sintering, floating resistance, high self-open rate and good safety performance.
Base on high quality magnesite and graphite as main raw materials, low carbon MgO-C bricks are produced via pressing and low temperature pre-baking and mainly used in slag zone of ladle lined with low carbon or carbon-free refractories for low and ultra-low steel production.
Fast Drying Castable for Iron Notch is made of corundum, high quality bauxite and silicon carbide incorporated with appropriate drying agent. By firing 2 to 3 hours, the products can be put into use, and show excellent performance.
