Core technology is emerging in recent years outside the refining furnace means a widely used practice in modern steel wire feeding technology. Cored wire alloy steel can be used to practice purification liquid steel to change the form of inclusions to improve the molten steel can be cast and mechanical properties, and can significantly improve the yield of iron alloy, reduce the cost of training of steel, and its significant economic effects. Feed line technology is the 85 countries to promote technology projects, is widely used as Deoxidizer, desulfurizer change inclusions in steel forms, improve quality. 
the production of calcium silicate alloy cored wire products, in line with the national and industry standards. With the production of multi-specifications, the ability of many species and can meet the technical requirements of various users. At present, a number of iron and steel enterprises in the country through the industrial test, having to feed uniform powder, regular geometry, and low line rate.
