Abstract：With the increasing pressure on energy and environmental protection in the steel industry, energy saving and emission reduction are inevitable choices for the high-quality development of steel companies. The principle of energy saving and emission reduction of oxy-fuel combustion technology and its application practice in ladle baking of a certain factory were described. The application effect of oxy-combustion on the 120 t ladle baking equipment of the plant was analyzed by industrial test comparison. The results showed that the application of oxy-combustion technology can effectively improve the baking effect of ladle, reduce the gas and NOx emissions during baking, reduce the gas consumption by about 43.79%, increase the lining temperature of the ladle baking end by about 223 ℃, reduce the molten steel temperature during converter tapping by about 9.10 ℃, and reduce the refining cost by about 4.77 yuan per ton of steel.
