On-line burner for baking steel ladles by using rich oxygen with compressed air

An on-line burner for baking steel ladles by using rich oxygen with compressed air comprises a burner body, wherein a compressed air nozzle is arranged on the burner body; a compressed air pipe is communicated with an oxygen pipe; and the ratio of the cross sectional area of the oxygen pipe to the cross sectional area of the compressed air pipe is 1:10. 10% of high-pressure oxygen is distributed in the compressed air, combustion of the rich oxygen with the compressed air can be realized, the temperature of flame is increased, and the temperature of steel ladle linings can be increased to 1,200 DEG C within 15 minutes. The on-line burner for baking the steel ladles by using the rich oxygen with the compressed air has the advantages of high temperature rise speed and short baking time, and can be widely used for baking devices for steelmaking steel ladles of steelmaking workshops.
