Calcium Aluminate Refining Slag

Pre-melted refining synthetic slag is a new generation of auxiliary material for steel making developed by our company. Its annual output is more than 20,000 tons. It can be used as purifying agent for molten steel when refining. It has strong deoxidation and desulfurization effect, which can reduce oxygen and inclusion content in steel. Besides, this product is made of a variety of fine materials after stirring evenly and melting at high temperature, which mainly produces calcium aluminate that contains more than 90 % 12CaO and 7AI2O3 with low melting point and easy to float upward. It can react with oxygen and sulfur in steel and adsorb reactants to purify molten steel. It has been proved by manufacturers who has been used this product: when the original sulfur content in steel is lower than 0.03%, the adding amount of it to per ton of steel is 3 to 8 kg, which can make the final sulfur content reach 0.0052%, and the desulfurization rate reaches more than 80%.

Product Features

While tapping, add into ladle and shock - LF furnace refining - VD furnace treatment. Under the condition of the original sulfur content is less than 0.030%, it can reach less than 0.015% after LF furnace treatment, and the sulfur content in steel can ultimately be less than 0.0101%.
