20th Century 50–70 years, China’s steel plants mainly used aluminosilicate refractory materials, including clay, alumina brick and so on. Since the 1980s, China has successively developed the aluminum-magnesium carbon, coal quality calcium and magnesium and other several series of new steel package refractories. Wherein the aluminum-magnesium carbon refractory materials are of varieties, all specifications, is …
