Dense Corundum

Dense corundum is a new type of high-purity refractory raw material made of high-purity alumina and reducing agent in a certain ratio, melted at high temperature in an electric arc furnace and then cooled. The main crystal phase of dense corundum is a-Al2O3, the main crystal phase is greater than 96%, and the porosity is less than 4%. It has good acid and alkali resistance, good wear resistance, corrosion resistance and volume stability at high temperatures. The color is Light gray, with high melting point, high volume density and very low porosity. It has excellent wear resistance, slag resistance, volume stability and thermal shock resistance at high temperatures. It is a corundum series refractory raw material Excellent refractory raw materials.

Ideal raw materials for making unshaped refractory materials such as blast furnace trench castables, ladle castables, ramming materials, and prefabricated parts, as well as various shaped products such as three major parts of continuous casting, breathable bricks, and nozzle seat bricks. It is widely used Steel, cement, ceramics, petrochemical and other industries. It is widely used in iron and steel metallurgy, petrochemicals, building materials, ceramics and other industries. It is mainly used as refractory ramming material for blast furnace tap troughs and aggregates for castables. It is also an excellent material for making steelmaking shrouds, slide plates and various corundum bricks.
