Chrome-corundum refractory brick is a type of high-quality refractory material that is widely used in many industries due to its excellent properties. It is made from high-aluminum bauxite clinker and chromium oxide, through high-temperature sintering.
Chrome-corundum refractory brick is classified into three grades: high-chrome, medium-chrome, and low-chrome. The high-chrome grade has the highest chromium oxide content of above 10%, while the low-chrome grade has a chromium oxide content of around 1%. The properties of the bricks vary according to the different grades, with the high-chrome grade having the highest fire resistance and corrosion resistance.
The technical parameters of chrome-corundum refractory brick are also important in determining its quality. The bricks should have a high refractoriness, above 1800℃, to withstand high-temperature environments. The bricks should also have high density and high compressive strength, in order to resist pressure. Additionally, the bricks should have low thermal conductivity and good thermal shock resistance.
The production process of chrome-corundum refractory brick is also critical. The raw materials need to be carefully selected to ensure the quality of the bricks. The production process involves mixing the raw materials, shaping the bricks using a mold, and then sintering the bricks at high temperature. The sintering process is the most important part of the production process, as it determines the density and strength of the bricks.
Overall, chrome-corundum refractory brick is a valuable material in many industries, including metallurgy, chemical industry, and cement industry. Its high-quality properties and production process make it a prefered choice for high-temperature environments and corrosive conditions. As technology and production processes continue to improve, chrome-corundum refractory brick will continue to play an important role in various industries.
