Abstract

The steel water tank is a key container for holding high-temperature liquid metal in the steelmaking system, and it serves as a production link connecting the steelmaking furnace, the refining furnace, and the continuous casting process. The working lining baking process of the steel water tank is an important research topic for steel enterprises. This paper systematically studies the application mechanism of the full-oxygen combustion technology in the baking of the steel water tank, the performance of the equipment, and the on-site data tracking. It analyzes the influence of key parameters such as the oxygen-fuel ratio on the baking effect; by eliminating nitrogen heat loss and improving the thermal efficiency of the steel water tank baking, the baking time of the steel water tank is shortened to 36.5%, and the gas consumption is reduced by 30% to 50%; CO₂ emissions are simultaneously reduced, and the NOx emissions are cut by more than 80% [1]. This technology provides an effective path for the steel industry to achieve green and low-carbon, as well as cost reduction and efficiency improvement, and has wide application value.
