Product Description
High Strength Fused Magnesia Alumina Chrome Spinel Brick For Cement Kiln And Glass Kiln
High chrome bricks are made of industrial grade chromium trioxide and alumina as the main raw materials, or introduce a small amount of zirconia, etc., after high temperature firing, the content of chrome trioxide is not less than 75%, chrome trioxide, alumina and Shaped refractory products with a total content of zirconia not less than 98%. 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 are divided into four grades according to the content of chrome 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, chrome, and brick respectively, and the Arabic numerals are the mass fractions of chromium trioxide.

The raw material used in the high chrome series products is a solid solution synthesized by high-temperature melting of alumina and chromium oxide in a certain proportion. The production process of special refractory materials is used to make refractory bricks, which can improve and enhance the internal quality of the product and the high temperature performance of the product. It has the characteristics of high refractoriness, high strength, good thermal shock stability, and strong corrosion resistance.Erosion, abrasion resistance, corrosion resistance, and structural spalling resistance have been used in metallurgy, glass, carbon black, and petrochemical industries.
The cinder erosion resistance of High chrome brick (1) The slag resistance of high chrome bricks. Coal melting is an acidic slag with a low melting point and is very corrosive to refractory materials. Both theory and practice show that high chromium bricks are refractory materials with good resistance to cinder erosion. (2) With the increase of temperature, the viscosity of coal slag is greatly reduced. (3) The large solubility of various refractory oxides in coal slag is lower than that of chrome oxide. (4) Erosion rate of furnace lining. With the increase of chromium oxide content, the corrosion rate of the furnace lining decreases. The relationship between lining erosion rate and chromium oxide content. (5) The anti-slag erosion rate of high chrome bricks with chrome oxide content of 60% ~ 90%. In order to lower the melting point of coal slag and ensure the smooth production, the coal water slurry A certain amount of lime (CaO) is added to the coal raw materials for the gasifier. Eventually, calcium oxide in the coal slag increases, and the corrosion resistance rate of high chromium bricks accelerates. The erosion rate of coal with different CaO content on high chromium bricks is different.
