Silicon Calcium Manganese main function

The main function of silicon-calcium-manganese is deoxidizer, warming agent and inoculant, etc. It is used for deoxidation and temperature increase in the steelmaking industry. Silicon and calcium in silicon-calcium-manganese composite deoxidation have a great affinity for oxygen. The affinity of calcium for sulfur It is also very large, and the deoxidation and desulfurization products are easy to float up and get rid of, which improves the performance of the steel, improves the toughness and impact resistance of the steel. Manganese can increase the manganese content in molten steel and reduce the amount of silicon-manganese alloy.

 

Therefore, the silicon-calcium-manganese composite deoxidizer is an ideal composite deoxidizer for both deoxidation and manganese-increasing in the steelmaking industry. Deoxidation of molten steel is an important part of steelmaking production. Conventional AL-containing deoxidizers include metal aluminum, silicon-aluminum-iron, silicon-aluminum-barium, etc., and their prices are generally high. Using AL deoxidizers for deoxidation, the deoxidation products generally contain AL2O3 The inclusions are harmful to the quality of the steel, and are likely to cause nodulation at the outlet. In order to overcome the shortcomings of AL deoxidation and reduce the cost of deoxidizers, silicon-calcium-manganese composite deoxidizers can be used in smelting processes such as electric furnaces, LF furnaces and converters.

 

 

When smelting high-quality steel, silicon-calcium-manganese is very beneficial to improve the quality of the steel; when smelting ordinary steel, using a synthetic deoxidizer can also improve the cleanliness of the steel and reduce the cost of deoxidation and desulfurization. This product has been approved by Egang , China Railway Steel Plant, Maanshan Iron and Steel Plant and other steel mills are regarded as ideal deoxidation and desulfurization alternative products. Recently, it has been used in steel mills in Changzhou to significantly reduce deoxidation, desulfurization and cost. Silicon-calcium-manganese has good deoxidation and desulfurization effects, which can meet the final deoxidation and desulfurization requirements of ordinary steel, low-carbon steel, and stainless steel. For example: if 1.2 kg of aluminum is added to one ton of molten steel, highly pure molten steel can be obtained. Then: 1○. For common carbon steel, it is used in converter smelting deoxidation alloying, add 1.2-1.5Kg/ton steel deoxidizer to the ladle. Deoxidation can be deoxidized from 220ppm to 70ppm. Replaced silicon aluminum barium (silicon aluminum barium calcium).
