■ Application in ferrous metallurgy

□ In addition to shortening the melting time, oxygen enriched blowing in electric furnace steelmaking strengthens the reaction of removing impurities and saves electric energy.

□ The "oxygen-enriched coal injection" technology is adopted for blast furnace ironmaking to reduce coke consumption and production costs and improve blast furnace productivity.

□ Oxygen-enriched blast of cupola can improve the temperature and fluidity of molten iron and improve the yield of castings.

□ Preheating and heating of oxygen iron cylinder and molten steel ladle for heating and cutting, heating before steel damage enters the rolling mill, and steel cutting
