Seamless Metal Calcium Desciption:

A kind of seamless metal calcium used for steel-making deoxidizing, is by the outer steel tube, protective coating, for calcium metal wire inner core of three parts; Seamless calcium solid core wire can reduce the vapor pressure of calcium metal and gasification rate, increase the seamless solid metal wire inserted depth of steel liquid calcium as well as reduce the boiling liquid steel, reduce the time of the metal calcium is absorbed by the molten steel, it is not only overcomes the existing joint calcium solid core wire inserted steel liquid boiling phenomenon, and reduce the uneven or hollow core powder and calcium powder line weight and affect the phenomenon of cored wire, avoid putting the harmful elements into calcium powder bag conductor, thus greatly improve the yield and stability of metal calcium.
