Abstract
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.
Description
Technical field:
The utility model relates to a kind of and steel-smelting device, particularly the steel-making apparatus for baking of ladle.
Background technology:
At present metallurgy industry steel-making is adopted the through type nozzle structure with ladle baking facilities more, be that air directly burns with the place of mixing of burning in pipeline of fuel, general baking can be baked to 1000 ℃ with the ladle lining in 30 minutes, its Shortcomings: combustion efficiency is poor, baking temperature of steel ladle is low, stoving time is long, and temperature upper limit is difficult to improve again, can not satisfy arts demand; Easily produce combustion instability, tempering and take off fiery phenomenon, incomplete combustion, the gas consumption amount is large, has potential safety hazard.In order to address these problems, people have done multiple effort, the technology that a key name is called " empty Gas multi-way junction road heat-accumulating burner " is disclosed such as Chinese patent CN201120248076.8 number, be provided with a plurality of gas nozzles that distribute ringwise by the nozzle body in the air nozzle periphery, this gas nozzle distributes cavity to be communicated with the annular that the setting of hull outside bottom is set.During work combustion air, combustion gas be divided into through burner and do gradually formula premixed combustion after some paths spray respectively.Can avoid combustion gas imperfect combustion phenomenon, improve service life and the efficiency of combustion of burner, reduce simultaneously noise.The deficiency that exists is complex structure, and cost is high.
The utility model content:
Overcome the deficiencies in the prior art, provide a kind of rational in infrastructure, can improve baking temperature of steel ladle, programming rate is fast, stoving time is short, allocate high pressure oxygen in compressed air into, the online oxygen enrichment companion compressed air ladle baking burner of Effective Raise flame temperature.Online oxygen enrichment companion compressed air ladle baking burner comprises that burner body, burner body are provided with compressed-air atomizer, connects oxygen hose at compressed air hose, and oxygen hose is 1:10 with the cross-sectional area ratio of compressed air hose.The utility model is allocated 10% high pressure oxygen in compressed air, can realize the burning of oxygen enrichment companion compressed air, improves flame temperature, can in 15 minutes ladle be served as a contrast temperature and be baked to 1200 ℃, has the advantage that programming rate is fast, stoving time is short.
Description of drawings:
Fig. 1 is online oxygen enrichment companion compressed air ladle baking burner view.
The specific embodiment:
Online oxygen enrichment companion compressed air ladle baking burner comprises that burner body 1, burner body are provided with compressed-air atomizer 2, connects oxygen hose 4 at compressed air hose 3, and oxygen hose is 1:10 with the cross-sectional area ratio of compressed air hose.
Claims (1)
1. an online oxygen enrichment companion compressed air ladle baking burner comprises that burner body, burner body are provided with compressed-air atomizer, is characterized in that: connect oxygen hose at compressed air hose, oxygen hose is 1:10 with the cross-sectional area ratio of compressed air hose.
