Refractory material classification and sodium feldspar used as raw material in refractory industry
Dec,11,2023
Refractory materials are the basis for all high-temperature industrial implementations and used in a wide variety of applications. This article summarizes the application of refractory materials in four major downstream industries: steel industry, cement industry, non-ferrous metal smelting industry and glass industry, including blast furnaces, converters, electric furnaces, pot furnaces, LF furnaces, RH vacuum refining equipment, Selection of different types of refractory materials for high-temperature equipment such as cement kilns, glass kilns, and non-ferrous metal smelting furnaces. What is refractory material? Refractory materials, according to international standards, refer to non-metallic (not excluding a certain proportion of metal) materials and products whose chemical and physical properties are stable and can be used normally in high-temperature environments. The American standard definition of refractory materials: non-metallic materials that can be made into structures and devices where temperatures exceed 1000°F based on their chemical and physical properties. According to Japanese standards, refractory materials are defined as shaped refractory materials that can be used at temperatures above 1500°C, and unshaped refractory materials, refractory slurries and refractory insulation bricks that have a maximum operating temperature of above 800°C. China follows international standards. Refractory materials are defined as non-metallic materials with physical and chemical properties suitable for...
