Discussion on melting point and boiling point of seamless calcium
Fundamental characteristics: melting point 850 ℃, boiling point 1.55g/cm3, melting degree close to zero in molten steel, great affinity for oxygen, and liquid calcium can dissolve Al2O3 doping.
Al2O3 in molten steel is mixed with calcium to form bulk liquid, which is easier to float up. The nozzle blockage caused by excessive Al2O3 in molten steel is reduced and the castability of molten steel is improved.
After calcium treatment, Al2O3 dopants adhere to spherical shape to improve the function after rolling.
Compared with the cored wire, the solid core wire has higher strength, better compactness and high calcium content. It can feed calcium to the deeper part of molten steel and stay below the critical depth for a longer time, s
