What is the Performance and Service Life of High Chrome Bricks?

图片
Performance and application range of high chrome brick High chromium bricks are made of industrial-grade chromium oxide and alumina as the main raw materials or introduce a small amount of zirconia. After high-temperature firing, a shaped refractory product with a chromium trioxide content of not less than 75% and a combined content of chromium trioxide, alumina, and zirconia not less than 98% is obtained. It has excellent corrosion resistance, high compressive strength at room temperature, high strength at high temperature, excellent wear resistance, high refractoriness, excellent thermal shock resistance, and good volume stability at high temperatures. High Chrome Bricks High chromium bricks are divided into four grades according to the content of chromium trioxide: GGZ-75, GGZ-85, GGZ-90, GGZ-95. In the grades, G, G, Z- are the initials of the Chinese phonetic alphabet of Gao, chromium, and brick respectively, and the Arabic numerals are the mass fractions of chromium trioxide. Hig
