Seamless metal calcium wire product advantages

Seamless metal calcium wire is a seamless solid metal calcium cored wire used for steelmaking deoxidation. It is composed of three parts: outer steel tube, intermediate coating, and inner core; the inner core is solid metal calcium (pure calcium) wire.

Advantages of seamless metal calcium wire: The seamless solid metal calcium cored wire provided by the utility model can reduce the vapor pressure and gasification speed of metal calcium, increase the depth of the seamless solid metal calcium cored wire inserted into the molten steel, reduce the boiling of the molten steel, and reduce the time for metal calcium to be absorbed by the molten steel.

It not only overcomes the boiling phenomenon of the existing seamed solid calcium cored wire inserted into the molten steel, but also reduces the phenomenon of hollowness or uneven weight of core powder in the powder calcium cored wire affecting wire feeding, and avoids the introduction of harmful elements (S, P, C, Si) in the powder calcium cored wire, thereby greatly improving the metal calcium recovery rate and stability. The cored wire has uniform wire diameter, high tensile strength, good toughness, and is not easy to break, which is more conducive to accurate control of wire feeding. The core wire is dense and tightly wrapped, so it can be stored for a longer time and still ensure the use effect.
