When used in steelmaking, it can purify the form of steel inclusions, improve the castability of molten steel, improve the service performance of steel, significantly improve the yield of alloy, reduce alloy consumption, reduce steelmaking cost, and have remarkable economic benefits

According to different use conditions, the types of silicon calcium cored wire selected are also different. Common products include solid core cored wire, metal cored wire, silicon calcium wire, carbon wire, etc. these products have their own different characteristics. Calcium silicate wire is also widely used in steel smelting, and has good effect in use. Our company provides many types of silicon calcium wire, ferrosilicon and other alloy products. The quality of these products has been strictly tested. The deoxidation performance of Ca is higher than that of Al, so the binding ability between Ca and O is stronger. Therefore, the gasified CA can react with the refractory inclusion Al2O3 to denature it to form calcium aluminate and other substances to float up. Linear velocity and linear rhythm are the key parameters of calcium silicate wire process. Too fast or too slow linear velocity and rhythm will affect the melting time and oxidation degree of solid core pure calcium wire, resulting in the impact on the metallurgical effect. The operator shall pay strict attention to the molten steel. Once the molten steel rolls violently, it is necessary to pause for a moment before continuing the linear process to prevent splashing. Therefore, when applying silicon calcium wire, we should always pay attention to the situation of molten steel. In fact, many types of additives will be added in steel smelting, and the effects of different additives are different
