With the continuous development of China's economy, alloy materials have also made great progress in production and development. Silicon aluminum barium calcium alloy material is currently produced and processed through smelting processes, such as electro silicothermic method and carbothermal method, which are commonly used to produce this alloy material.
Si Al Ba Ca alloy is mainly used in China's steelmaking industry, and has good deoxidization performance, which is favored by the majority of users. It can continuously deoxidize, promote the rapid polymerization of some non-metallic impurities in the molten steel, significantly improve the morphology of inclusions, and play a role in purifying the molten steel; Improve the recovery rate of silicon, manganese and other alloys, which can reduce the addition of carbon powder, save resources and reduce costs; The deoxidation effect is good, which plays a role in the nodulation problem of the casting nozzle and makes the steel water flow better; The operation is simple. When we use this material, it can be completed without other new equipment. Si, Al, Ba, Ca has the characteristics of low melting point, fast diffusion, spheroidizing inclusions in molten steel, changing the shape of inclusions, rapid tapping and shortening smelting time. The production of calcium aluminosilicate barium requires certain technology. For example, when some elements are added, calcium oxide and coke should be added in batches to promote the formation of calcium silicate aluminum, and then barium ore and coke should be added in batches to promote the formation of silicon calcium barium aluminum alloy. The method of braising and burning shall be adopted from beginning to end, and the slags shall be treated by adding calcium oxide and barium oxide to exclude them from the furnace. Considering the improvement of refining effect and energy saving, the steelmaking method without slag or with less slag is proposed.
