Abstract

PURPOSE:To provide the low carbon high manganese steel without consuming manganese in the steel, by decarbonizing and refining the high manganese steel supplying an inert gas from a tuye re under the level of a bath and oxygen from an upward blowing lance. CONSTITUTION:Low carbon usual steel is first ingotted by an upward blowing method using the converter provided with a tuye re under the bath level of the upward blowing converter. After the removal of slag, high carbon ferromanganese is added to the usual steel to provide the high manganese molten steel having the prescribed percentage of manganese. Subsequently the molten steel is decarbonized to the prescribed percentage of carbon by supplying an inert gas from the tuye re under the bath level and blowing oxygen from the upward blowing lance. Since these treatments are carried out in the same converter, the heat loss is small and the operating efficiency is high. The supply of the inert gas and oxygen as mentioned above keeps the nozzles free from blocking and fusion loss and permits the free control of oxygen flow amount. Further, there occurs no evaporation of manganese due to a high vacuum. Moreover, the refining can be performed by the method in a sufficiently high yield of manganese even without the use of a slag forming agent, but it is better to adjust the slag forming agent to the slag composition meeting the formula.
