One kind of low carbon high manganese steel smelting method

The present invention discloses a method for smelting low carbon high manganese steel, molten iron desulfurized blended converter, the control endpoint carbon content of 0.03 to 0.05%, the steel oxygen value 400 ~ 500ppm, temperature control in the 1660 ~ 1680 ℃ ; RH into the furnace temperature is higher than 1610 deg.] C, the removal of carbon to 0.01% or less; the RH treatment furnace well blended steel converter, against the molten steel before, converter furnace added to the mixture of manganese metal and aluminum alloy for manganese; against the molten steel after shaking the furnace, the blowing point of the gun, until completely melted alloy steel furnace, temperature controlled above 1600 deg.] C; LF into the furnace, such as a temperature below 1530 deg.] C, first raised to a temperature above 1530 deg.] C then Mn alloying, LF furnace carry-out temperature is greater than 1500 ℃. The present invention can be stable steel final manganese content at 15% to 20%, the carbon content is controlled to 0.05% or less, to solve the conventional converter, not refining of low carbon high manganese steel production problems.
