Punching deslagging device of metallurgical furnace

Abstract

The invention discloses a punching deslagging device of a metallurgical furnace. The device comprises a slag hole copper water jacket and a copper water jacket plug, wherein copper pipes are pre-buried in the slag hole copper water jacket and the copper water jacket plug; the copper water jacket plug is assembled in the slag hole copper water jacket; a through hole is formed in the axial center of the copper water jacket plug. According to the device, the copper water jacket plug is additionally arranged in the slag hole copper water jacket, the slag hole copper water jacket and the copper water jacket plug are fixed and limited relative to each other through a steel plate connected to lug bosses at the outer end of the slag hole copper water jacket, and the copper pipes are pre-buried in the entities of the slag hole copper water jacket and the copper water jacket plug; when deslagging is needed, all that is needed to do is remove sealing putty in the through hole in the center of the copper water jacket plug; the slag hole copper water jacket and the copper water jacket plug are both copper cooling pieces; the device overcomes the defects in the prior art that a slag hole steel water jacket deforms seriously and is reduced in strength due to corrosion of slag so as to be liable to leak water and the furnace needs to be shut down when the slag hole steel water jacket is replaced, thereby improving the practicability and safety performance of the metallurgical furnace, prolonging the service life of the metallurgical furnace and saving cost.

Description

technical field [0001] The invention relates to a punching and slagging device for an oxygen-enriched smelting furnace and an oxygen-enriched reduction furnace suitable for continuous operation. Background technique [0002] The current metallurgical furnace slagging is mainly composed of the slag mouth molten steel jacket. The service life of the slag mouth steel water jacket is short and the risk is high. It is often necessary to stop the furnace to replace the water jacket. Frequent start and stop of the furnace will seriously deform the slag mouth steel water jacket, weaken its strength, and easily leak water, causing the explosion of the melt in the furnace and the furnace is dangerous. The coefficient is generally large. Contents of the invention [0003] The object of the present invention is to provide a metallurgical furnace punching and slagging device with long service life and no need to stop the furnace for replacement. [0004] The metallurgical furnace...
