Products Description
The alloys used in steelmaking are generally large pieces of alloys, and when cast iron is used as an inoculant, it is in powder form. In cast iron, silicon barium alloy is an efficient and long-lasting inoculant. During the casting process, silicon-barium inoculant is added to the molten iron. The cast iron products produced show good decay properties and reduced cross-section sensitivity. , generally what we call inoculant refers to silicon barium inoculant.

1.There are two ways to smelt silicon barium alloy. The first is a one-step smelting method. Barite (barite is a mineral containing barium element), silica, coke, steel scraps, and silicon carbide are added to the submerged electric furnace. Smelting. The second is the two-step smelting method. First, ferrosilicon is smelted in a submerged thermal electric furnace, and then the ferrosilicon and barium-containing raw materials are added to the intermediate frequency furnace for smelting and refining to obtain the desired silicon-barium alloy. Both methods consume very high power.
2.The smelted silicon barium can be used as a deoxidizer and alloy additive. The silicon barium alloy is used as a deoxidizer in steelmaking. Adding it to steelmaking will reduce the occurrence of smoke and flames and change the properties and distribution of non-metallic inclusions in steel. Improve the cutting performance of metal, and when barium and calcium elements are used in steelmaking temperatures, barium can reduce the vapor pressure of calcium, significantly improving the use effect of calcium. Therefore, silicon-barium alloys are rarely used simply as deoxidizers. Silicon Barium alloys are usually smelted into multi-component alloys with calcium and aluminum. The deoxidation and desulfurization effects are very good. Currently, the commonly used multi-component alloys are silicon aluminum barium, silicon barium calcium, silicon aluminum barium calcium.
