Title: Production of low carbon steel
Inventor: KOROGI SHOHEI
IPC: C21C7/10
Filed: 1989-03-17
Abstract: PURPOSE:To improve decarbonizing velocity and enable efficient and stable melting of a dead soft steel by forming flowing of the molten steel to gravity direction with electromagnetic force at the time of producing the steel having <=30ppm C content in a vacuum treating furnace. CONSTITUTION:An electromagnetic stirring device 2 is set at e.g. position of (a) or (b) in an RH vacuum vessel 1 so that the vertical molten steel flow generates. Then, the molten steel in a ladle 4 is forcedly stirred with flow of the gravity direction through submerged tubes 3. By this method, the decarbonizing velocity in low carbon range is drastically improved and the dead soft steel having <=30ppm C content and further the ultra dead soft steel having <=10ppm C content can be stably produced in a short time, which can be sufficiently satisfied in industrial. Therefore, at the time of coming to less than 100ppm C content in the molten steel, the molten steel flow forming operation with electromagnetic force is preferably started, and after charging deoxidized agent, this is stopped.
