What is silicon calcium carbon complex deoxidizer

Silicon calcium carbon complex deoxidizer contains high calcium, calcium participates in deoxidation reaction, and AL: O in liquid steel. SiO: Forms a low melting point compound, easy to float. The carbon in the mixture produces the carbon-oxygen reaction, promotes the stirring of the molten steel in the packet, accelerates the floating of the deoxidation products, thereby improving the quality of the molten steel and improving the fluidity of the molten steel, and improves the utilization rate of the alloy. At the same time of deoxidation reaction, there is a certain desulfurization effect. Silica-calcium-carbon complex deoxidizer is an ideal compound deoxidizer in steelmaking industry. The Silicon calcium carbon composite deoxidizer is put into the ladle manually by the following method (1) adding method. (2) Before adding time to the steel, put 1/2 into the ladle. Once the steel is out, put in the remaining half. Then alloying is carried out according to the regulations. (3) The amount of deoxidizer is added according to the amount of one kilogram per ton of steel. Aluminum consumption decreased from 1kg/T steel to 0.3kg/T steel; Calcium silicon is no longer used, and the amount of ferrosilicon and ferromanganese can be reduced from the upper limit to the middle limit. Silicon calcium carbon composite deoxidizer saves a lot of energy and alloy, and can simplify and standardize the deoxidation and alloying process, providing conditions for automatic control of steelmaking process and off-furnace refining operations. After the use of the deoxidizer, the silicon calcium alloy can be used, and the aluminum can be saved by more than 70%, greatly reducing the cost of steelmaking. Required weight (5K/bag) sealed in plastic bags, and then sealed in iron drums before the furnace for use. The general storage period is one week.
