Technical Key Points
Blowing argon to the steel to reduce inclusions. Take 2t ladle as example, when tapping the molten steel, gas pressure should be strictly controlled below 0.1Mpa to prevent the new Oxygen absorption effect, which may be caused by Violent turbulence if the blowing gas is with high pressure. Argon blowing process can effectively reduce oxygen content of the steel by 10% -20%, the effect is very obvious. after tapping of the high temperature molten steel, the steel must be sedated for 5 minutes, thus the gas solubility in steel will reduce and some gas will escape from the steel, carrying the inclusion inside rise to the surface of the steel, thus the steel are cleaned.
