IPC: C21C7/072
Filed: 1981-06-12
Abstract: PURPOSE: To prevent economically and highly practically a nitrogen absorption of molten steel, by closing a sealing device of a converter open port and a suction damper to stop gaseous N 2  sealing around the port and a purging of waste gas in the converter during the period from the beginning of reduction to finish.  
     CONSTITUTION: At the decarbonization refining of high Cr steel, a hood 4a is lifted to release a converter open port 2a, and a suction damper is opened properly. A top-blown  lance is inserted into the refining converter 2 from the port 2a to perform an oxygen top-blowing, and a purging of waste gas in the converter is performed by sealing the circumference of the port 2a with gaseous N 2  to prevent an occurring of explosion of gaseous CO. At the last period of decarbonization or from the beginning of reduction period at the latest, the hood 4a is descended to close the port 2a, and the damper 5 is full closed to stop the sealing by gaseous N 2  and the purging of waste gas. Gaseous Ar is supplied continuously from a tuyere 1 after that. In this way, the amount of gas in the converter is decreased, and an entering of air is prevented even after the last period of the decarbonization, and the absortion of nitrogen of the molten steel is prevented by keeping the partical pressure of the N 2  in the converter in a low press.
