Method for controlling end point manganese alloying of high-manganese steel converter

The invention discloses a high manganese steel converter end point manganese alloying control method, which comprises the following steps of: baking an alloy by adopting an alloy baking device, and preheating the alloy to about 300 DEG C; the converter end point adopts high-temperature control, and the carbon catching temperature of the converter is controlled to be 1660 DEG C or above; the end point of the converter is controlled through in-furnace pre-deoxidation operation, and the influence of the oxygen content of the end point of the converter on the alloy yield is reduced; and converter bottom blowing adopts high bottom blowing strength control to ensure full stirring and alloy melting. The invention aims to provide the control method for the end point manganese alloying of the high-manganese steel converter, so that the problems of adding a large amount of alloy and large temperature drop in the refining process are solved, partial alloying operation control in the converter process is realized, and th
