Feuerfester Ziegel unverbrannter Al2O3-SiC-C Steine

Refractory brick : According to the working condition, the inner lining material should features good resistance to slag corrosion, especially due to desiliconization desulfurization and dephoshorization(hereinafter refers to 3-de), thermal shock stability, high mechanical strength, resistance to erosion and abrasion(especially on at impacting area).
