China is the the world refractory largest consumer of building materials industry will maintain steady development, the total demand for refractories is still and will continue to maintain a rapid growth trend.
In the past 30 years, due to refractory study the deepening of the endless stream of innovative high-quality refractory. The industrial industry has been in close contact with the refractory sufficient power. To industrial efficiency continues to improve, thus contributing to the progress of the industry a wide variety of refractory materials, widely used, usually divided into high and low refractoriness ordinary refractory (1580 to 1770 ° C), high-grade refractory (1770 to 2000 ° C) and super refractories (2000 ° C); divided into acidic refractory chemical properties. ZTE refractory materials and basic refractories. Here there is a special refractory
Refractoriness is not lower than 1580 ° C in a class of inorganic non-metallic materials. The refractoriness is refractory cone specimen in the absence of load, resistance to high temperatures without the softening melting down Celsius temperature. Refractory materials are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, silicate, power and other industries, the largest amount in the metallurgical industry, accounting for 50% to 60% of the total output.
The physical properties of the refractory structure and properties, thermal properties, mechanical properties, performance and job performance.
Refractories thermal properties including thermal conductivity, thermal expansion coefficient, specific heat, heat capacity, thermal diffusivity, thermal emission rate.
Performance of the refractory refractoriness, refractoriness under load, reheating linear change, thermal shock resistance, slag resistance, acid resistance, alkali resistance, resistance to water resistance, anti-the CO erosion resistance, electrical conductivity, and so on.
Refractories, silica brick, clay brick, silicon carbide, castable.
