Abstract：The steelmaking plant of Benxi Iron and Steel Co.， Ltd. is restricted by the transportation between processes， and has extremely strict requirements on tapping temperature. The control level of various steelmaking indicators is low， and the carbon emission level is high. In order to solve such problems， through process technology research and development and innovation， the control technology of converter low temperature and low oxygen tapping is promoted， so as to reduce energy consumption， improve the quality of molten steel， reduce the consumption of deoxidized aluminum， reduce the consumption of steel materials， improve the negative energy steelmaking indicators， and reduce carbon emissions， Achieve peak carbon neutralization.

Key words：Converter； Low temperature and hypoxia； Negative energy steelmaking； Carbon emission
