Our factory have three categories of refractory materials: Acid, Basic & Neutral. Apart from these we can classify refractories into few more categories like – Special refractories, Insulating Refractories, & Cermets. Refractory materials are non-metallic materials with refractoriness not less than 1580℃. Widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, power and other industrial …

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 …
