Description

Technical Field

[0001] The utility model relates to the technical field of copper discharge chutes, in particular to a novel copper discharge chute. Background Art

[0002] The matte of the Osmed furnace sedimentation electric furnace is discharged through the chute. The electric furnace chute is a unique device that uses the principle of drilling copper to achieve continuous discharge of the melt. It is the link between the next process and the electric furnace and a key point. It is the only channel for the normal flow of the melt. Its smoothness is related to the continuity of the entire production chain. The temperature of the electric furnace matte is about 1200℃. When the matte flows into the chute, it will obviously flush the chute. At the same time, the matte will be bonded to the chute when it is cold or splashed during the flow process, which will significantly reduce the fluidity of the melt. When the thickness of the bonded matte reaches a certain level, it must be cleaned in time to ensure the fluidity of the matte. However, the cleaning is very troublesome, time-consuming and labor-intensive, and when the matte is discharged, a large amount of smoke will be generated to pollute the environment. In order to solve the above problems, a new type of copper discharge chute is proposed. Summary of the invention
