Silicon barium particles are used as inoculants for casting and deoxidizers for steelmaking. When used as inoculants for casting, they can promote the formation of type A graphite, refine the eutectic clusters, improve the distribution of graphite, have strong anti-decay ability, eliminate and prevent the tendency of white cast iron in castings, and reduce cross-section sensitivity. When silicon barium particles are used as deoxidizers for steelmaking, there is no smoke or sparks, and the deoxidation effect is higher than that of silicon calcium alloy. It can also improve the morphology of non-metallic inclusions and improve the quality of steel.
Silicon barium particles are smelted in a submerged arc furnace at one time. This process is based on the smelting of 75% ferrosilicon. When producing this product, first of all, the original production of 75% ferrosilicon furnace conditions are required to be normal, and the aluminum content must be controlled below 2%. The barite, limestone, and calcium carbide are mixed evenly in proportion, and placed on the furnace platform facing the three electrodes respectively, and then mixed evenly with 75% ferrosilicon. Within 1.5 hours of each iron tapping (one furnace of iron tapping every 2 hours), the above mixed furnace materials shall be added into the furnace in batches and stages, and fire shall be prevented during smelting. The furnace construction, start-up and shutdown processes are the same as the 75% ferrosilicon process.
