ferro silico calcium
Iron Alloy Calcium Aluminate Flux Ferro Alloys Deoxidizer AlCa Alloy Flux A
Calcium aluminate is a series of inorganic compounds sintered from calcium oxide and aluminum oxide at high temperatures. It is used in cement and fire extinguishing materials due to its high hardness and high melting point. Calcium aluminate products are divided into three categories: water treatment, steelmaking slag removal agent and high alumina cement.
The fused calcium aluminate (premelted aluminum-calcium slag) is mainly used for removing sulphur, oxygen and other impurities in the molten steel in the LF furnace, open hearth furnace and converter ladle refining, and reducing the content of harmful elements and impurities in the steel. Suitable for ordinary carbon steel, high carbon steel, high and low alloy steel.
he calcium aluminate production method is to crush the bauxite and limestone into balls and send them to the rotary kiln. After calcination at 1300 °C, the crushed package is a calcium aluminate product.
The dissolution rate of alumina in the acid solution can reach more than 90%.
Al₂O₃: A white solid that is hardly soluble in water. Odorless. Tasteless. Very hard. Easy to absorb moisture without deliquescence (burning does not absorb moisture). Amphoteric oxide, soluble in inorganic acids and alkaline solutions, almost insoluble in water and non-polar organic solvents. Relative density (d204) 4.0. The melting point is about 2000 ° C.
CaO: White or with gray blocks or granules. Sensitive to humidity. Easy to absorb carbon dioxide and water from the air. Dissolved in water to form calcium hydroxide and produce a lot of heat, soluble in acid, glycerin and sucrose solutions, almost insoluble in ethanol. The relative density is 3.32 to 3.35. The temperature of 2572 ° C. The boiling point is 2850 °C. The refractive index is 1.838. Corrosive.
