Seamless metal calcium cored wire
Therefore, the air in the space behind the traditional calcium wire will reduce a lot of calcium content, affecting the output of molten steel, and the yield rate is reported to be 12%. There is no such phenomenon in the calcium seamless line. The test conclusion of Magang is that the yield rate of three is 37%. The conventional wire stitching in terms of use, the buckle of calcium, and the skin are ordinary carbon steel. It is easy to break the feed line and the wire card phenomenon during use. The seamless calcium wire has no such phenomenon after yellowing treatment.
Seamless calcium wire is a solution for adding calcium to molten steel. It is a solid calcium core welding wire that has undergone professional manufacturing process from the original factory. Therefore, this product can use ordinary wire feeding equipment to penetrate the solid calcium in the seamless steel strip into the molten steel, establish the industry standard for the basic properties of calcium metallurgy, and is reliable and repeatable. The melting point is 850℃, the boiling point is 1480℃, the density is 1.55g/cm3, the melting point in molten steel is close to zero, and it has a great affinity for oxygen. Liquid calcium can dissolve Al2O3 inclusions.
Al2O3 forms larger liquid inclusions in molten steel after calcium treatment, which are easy to float. It reduces nozzle blockage caused by excessive Al2O3 content in molten steel and improves the pouring capacity of molten steel. After calcium treatment, Al2O3 inclusions remain spherical and the performance after rolling is improved.
