Calcium aluminate(Premelted calcium aluminates residue) is mainly used for separating the impurity elements such as sulfur and oxygen in ladle refining of LF furnace, open hearth furnace and the converter furnace, and it can reduce the content of harmful elements and impurities, which is applicable for general carbon steel, high carbon steel, high and low alloy steel. It's applications have already been mature in some foreign countries, such as South Korea, Japan, the United States and the developed European countries. Calcium aluminate advantages: 1) Uniform chemical compositions, low melting point, high melting speed, and short smelting time; 2) It has no fluoride and doesnt erode furnace lining and ladle, and it is compact, non-absorbent,and easy to storage as well; 3) Stable phase and fast dust-reducing speed, rapid desulfurization effect stabilized at 60%, and suppresses phosphorus into molten steel; 4) Improving the protective effect and reducing erosion to ladle lining. In addition,we can organize mass production according to the different chemical composition requirements of the customers and keep confidential for them. Q1.

Description: Calcium Aluminate for Metallurgy is a kind of auxiliary material for steelmaking, as it speeds up secondary metallurgy process, especially faster desulfurization, Improves overall steel cleanliness and makes high grade steel with cheaper cost. Tundish Flux: 0-2mm, 3-8mm Ladle Refining Slag:5-30mm, 5-50mm Packing:1 MT big bag or as per requirement Calcium aluminate advantages: 1) Uniform chemical compositions, low melting point, high melting speed, and short smelting time; 2) It has no fluoride and erode furnace lining and ladle, and it is compact, non-absorbent, and easy to storage as 3) Stable phase and fast dust-reducing speed, rapid desulfurization effect stabilized at 60%, and suppresses phosphorus into molten steel 4) Improving the protective effect and reducing erosion to ladle lining.

Calcium aluminate is a series of inorganic compounds which are sintered at high temperature by calcium oxide and alumina. Due to its high hardness and high melting point, it is used in cement and fire extinguishing materials.The general formula is mCaO nAl 2 O 3, and the abbreviated form is CmAn (m, n equals 1).Calcium aluminate products are divided into three categories: water treatment, slag - making and high alumina cement.

Characteristics of sintered calcium aluminate: 1) Uniform chemical composition, low melting point and fast melting speed can shorten the refining time; 2) No fluorine, no erosion of furnace lining and ladle; 3) Compact structure, no water absorption, easy storage and transportation; 4) Due to the stable phase and fast slag formation, it can reduce the dust pollution to the iron and steel plant and comprehensively stabilize the refining process; 5) It does not contain impurities such as hydrogen, nitrogen and carbon, which is conducive to improving the quality of steel. Sintered calcium aluminate (premelted aluminum calcium slag) is mainly used in LF furnace, open hearth furnace and converter ladle refining to remove impurities such as sulfur and oxygen in molten steel and reduce the content of harmful elements and impurities in steel. It is suitable for ordinary carbon steel, high carbon steel, high and low alloy steel.

Fused Calcium Aluminate is fused in the electric arc furnace with the high quality raw materials. It is an indispensable refining agent in the process of refined steel making in steel industry. It is characterized by very strong desulfurization and deoxygenation, low melting point,high melting speed, it can shorten smelting time, reduce the energy consumption,reduce dust pollution in the steel plant, and good safety performance,good arc burying effect, reduce the erosion of lining by the arc, increase the service life of the ladle. This product does not absorb the water, does not powder, and easy to store and transport.
