The production process of calcium aluminate powder is exquisite and applied in various fields
2019-08-07
Calcium aluminate powder is made of high grade aluminous vanadium and limestone through crushing, drying, ball milling, briquetting, calcination, powder grinding into a water purifier polyaluminium chloride manufacturing special raw materials, industrial products are off-white, slightly soluble in water, the aqueous solution is alkaline, PH value of about 11.
The chemical composition of calcium aluminate produced by Weida is uniform, low melting point, fast melting speed, which can shorten the smelting time; it does not contain fluorine, does not erode the furnace lining and ladle; it has a dense structure, does not absorb water, and is easy to be stored and transported in warehouses; because the physical phase is stable, it becomes slag fast, which can reduce the dust pollution of the steel plant and stabilize the refining process; it does not contain impurities such as hydrogen, nitrogen and carbon, which is conducive to improving the quality of steel. It is confirmed by users that the stability curve function of our calcium aluminate products with time is almost a straight line. It avoids the wave-like and jagged curve function of low-grade products (sintered products and cupola raw products), which brings many unsuitable phenomena to metallurgical production.
Calcium aluminate powder electric fusion calcium aluminate (pre-melting calcium aluminate slag) is mainly used in LF furnace, flat furnace, converter ladle refining, to remove sulfur, oxygen and other impurities in the steel, reduce the content of harmful elements and impurities in the steel, for ordinary carbon steel, high carbon steel, high, low alloy steel. It has long been used in foreign countries, such as Korea, Japan, Europe and the United States and other developed countries!
