Refractory Material Brief Introduction

Fire resistance of at least 1580class of inorganic non-metallic materials. Refractoriness of refractory conespecimens failed under load conditions, resistant to high temperatures without softening-melting down to the Celsius temperature. But in refractoriness as defined by is not only comprehensive description of fire-proof material, 1580 is not absolute. Is defined as where the physical and chemical properties allow its use in high-temperature environment of material known as refractory materials. Refractory materials are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, Portland, power and other industrial areas, most commonly used in the metallurgical industry, accounting for 50%~60% of the total production.
