Description

Technical Field

[0001] The utility model relates to the technical field of burners, in particular to a burner for a submerged arc furnace. Background Art

[0002] The submerged arc furnace burner, also known as an arc burner, is mainly used to form an arc at the furnace mouth of a submerged arc furnace to burn through or repair the tapping hole. The burner consists of a carbon rod, a handle, and a conductive component. When in use, a worker needs to hold the operating handle and push the burner to bring the front end of the carbon rod close to the furnace eye, and use the arc heat generated at the front end of the carbon rod to melt the mud ball.

[0003] The common burners for submerged arc furnaces have a relatively simple structure. Most of them are suspended and installed with an adjustable angle. When in use, it is necessary to manually push the burner forward or adjust the angle, which consumes a large amount of manpower. Moreover, the manual control force at multiple angles is poor, and the overall burner is prone to deviation during use, resulting in insufficient practicability. Therefore, we propose a burner for a submerged arc furnace. Summary of the Invention
