Advantages of seamless metal calcium cored wire
Seamless calcium metal cored wire is a kind of seamless solid calcium metal cored wire used for steelmaking and deoxidation. It is composed of outer steel tube, intermediate coating and inner core. The inner core is a solid calcium (pure calcium) cored wire. Seamless metal calcium cored wire edge, can reduce the vapor pressure of calcium metal and gasification rate, increase the seamless solid metal conductor inserted depth of steel liquid calcium package and reduce the boiling liquid steel, reduce the time of the metal calcium is absorbed by the molten steel, calcium is not only overcomes the existing joint solid package conductor inserted steel liquid boiling phenomenon, and reduce the calcium powder package conductor hollow or uneven core powder weight and affect the phenomenon of cored wire, avoid the harmful elements in calcium powder bag conductor (S, P, C, Si) into, thus greatly improve the yield and stability of metal calcium. The cored wire has uniform diameter, high tensile strength, good toughness, and is not easy to break, which is more conducive to the accurate control of wire feeding. The core wire is compact and tightly wrapped, which can be stored for a longer time and ensure the use effect.
