| titleOfInvention | High speed refining method of low carbon stainless steel |
| abstract | The present invention relates to a method for refining low carbon stainless steel;n n n Its purpose is to provide a high-speed refining method for low carbon stainless steel by using both a top lance and a side chuck.n n n The present invention for achieving the above object is an AOD comprising a top lance for blowing decarburized gas in the upper portion of the molten stainless steel containing 1.8-2.2% by weight of carbon, and a tuyere for blowing a stirred gas into the molten steel In the refining method of 10-12% by weight Cr-containing low carbon stainless steel using a refining furnace,n n n A first refining step of injecting oxygen into the molten steel with the upper lance and further blowing a mixed gas of oxygen and an inert gas with a horizontal take-up gas to decarbonize the carbon in the molten steel to 0.4-0.5%; The mixed gas of oxygen and inert gas is blown into the molten steel decarburized in the first refining step in a ratio of 1: 1-1: 3, and the mixed gas of oxygen and inert gas is blown with a horizontal take-up tour, At this time, the oxygen gas of the intake lance is A second refining step blown into a ship and decarburized carbon in molten steel at 0.03-0.04%; Andn n n And a third refining step of blowing a mixed gas of oxygen and an inert gas into the molten steel decarburized in the second refining step by decarburizing carbon in the molten steel to 0.02% or less. That's the point. |
