Calcium aluminate powder is made of high grade bauxite and limestone by crushing, drying, ball milling, billet making, calcination, grinding made of a water purification agent polyaluminum chloride manufacturing of special raw materials, industrial products are gray, slightly soluble in water, aqueous solution is alkaline, PH value of about 11.

The electrofused calcium aluminate produced by Weida Company has uniform chemical composition, low melting point and fast melting speed, which can shorten smelting time. No fluorine, no erosion of furnace lining and ladle; Compact structure, no water absorption, convenient storage and transportation; Due to stable phase and fast slag formation, it can reduce dust pollution to steel plants and stabilize refining process. It does not contain hydrogen, nitrogen, carbon and other impurities, which is conducive to improving steel quality. Confirmed by the user, the factory electrofused calcium aluminate products use stability with time curve function is almost a straight line. To avoid the middle and low-grade products (sintered products and cupola raw products) wavy, serrated curve function to metallurgical production brought many unsuitable phenomena.

Calcium aluminate powder electric melting calcium aluminate (pre-melting aluminum calcium slag) is mainly used for LF furnace, open hearth furnace, converter ladle refining, remove sulfur, oxygen and other impurities in molten steel, reduce the content of harmful elements and impurities in steel, suitable for carbon steel, high carbon steel, high and low alloy steel. In foreign countries have long been mature applications, such as South Korea, Japan, Europe and the United States and other developed countries!
