| titleOfInvention | A method for manufacturing high chromium stainless steel using exhausted gas analysis |
| abstract | The present invention relates to a method for producing high chromium stainless steel; The purpose is to provide a method for producing high chromium stainless steel that is easily decarburized to the final target level by appropriately controlling the decarburization reaction efficiency through the change of CO and CO 2 content in the flue gas in the process of refining high chromium stainless steel.n n n The present invention relates to a method for producing stainless steel containing 18% to 30% Cr and 0.01% or less C by weight, in the range of 0.2 to 1.0% by weight of molten steel in a refining furnace (AOD) or converter. The first refining step, and the final refining of the first refined molten steel in vacuum refining (VOD), the final refining is oxygen blowing in the upper lance while lowering the inert gas of 5 ~ 10Nℓ / min per ton molten steel Initiation of oxygen is terminated when the concentration of [CO + CO 2 ] in the flue-gas generated during the decarburization process reaches 45-55% from the start of blowing, and then 10 ~ / tonne of the molten steel with the vacuum in the VOD of 10 mbar or lower. The technical gist of the method for producing high chromium stainless steel using flue gas in which 20 N l / min of inert gas is reduced for 15 to 25 minutes, followed by ordinary deoxidation treatment, and continuous casting of the deoxidized molten steel. |
