Description
Refractory materials refer to a type of inorganic non-metallic materials with a fire resistance of not less than 1580 ℃. Refractory materials are widely used in industries such as metallurgy, chemical industry, petroleum, machinery manufacturing, silicates, and power. They have the largest usage in the metallurgical industry, accounting for 50% to 60% of the total production.
Acidic refractory materials are mainly composed of silica, and commonly used ones include silica bricks and clay bricks. Neutral refractory materials are mainly composed of alumina, chromium oxide, or carbon. Alkaline refractory materials are mainly composed of magnesium oxide and calcium oxide, and magnesium bricks are commonly used.
