Refractory castable for rotary kiln is suitable for calcination and roasting of cement, limestone,magnesia, ilmenite and non-ferrous metal ore. Castable for rotary kiln has the advantages of strong acid and alkali corrosion resistance and good wear resistance and long service life.
The acid-resistant refractory bricks produced by our company adopt high-grade refractory aggregates, powders, additives, etc. After reasonable grading and high-temperature firing, they can fully meet the acid and high temperature resistance of furnace lining refractories under various acid regeneration process conditions.
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.
