Advantages of seamless metal calcium wire products
Seamless metal calcium wire is a seamless solid metal calcium cored wire used for steelmaking deoxidation. It consists of three parts: outer steel pipe, intermediate coating, and inner core; the inner core is solid metal calcium (pure 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 the core powder of the powder calcium cored wire affecting the feeding of the wire, 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 the wire feeding amount. The core wire is dense and tightly wrapped, and can be stored for a longer time and can also ensure the use effect.
