Basic Refractory are mainly composed of magnesium oxide and calcium oxide, commonly used as Magnesia bricks. MAGNESIA brick containing 80% ~ 85% MAGNESIA has good resistance to alkaline slag and iron slag, and higher fire resistance than clay brick and si

Refractory products with periclase as main mineral component. According to the composition of raw materials, it can be divided into: Magnesia brick made of magnesia brick and Magnesia brick made of magnesia brick and Magnesia brick made of magnesia brick

It is predicted that in the next five years, the average annual consumption of steel Refractory per ton will decrease by 0.5 ~ 1.0 kg, and in 2005, the per ton consumption of steel Refractory in China’s iron and steel industry will decrease to 28 kg. Base

According to the compactness and shape of the products, there are sintering method, melting casting method and melting injection method. Sintering method is to pre-burn some raw materials into clinker, crushing and screening, and then according to a certa
