Quality factors of materials used in furnace construction Quartz acid furnace lining materials are generally used. The silicon content of quartz sand and quartz powder should be above 99.5%, with oily crystals, transparent and free of impurities. (Silicon content 99.85%, hardness 8, density 2.65, refractoriness 1850 degrees). Binder factors used in furnace construction Traditional furnace…

The generation mechanism of the slag circle: The temperature of the protective slag at the meniscus near the slag crystallizer is only 1200~1300°C, and so-called slag circles often appear during casting. The formation of the slag ring is caused by the adhesion of the sintered layer and the semi-molten layer of the mold slag in…
