Description

Technical Field

[0001] The utility model relates to the field of continuous casting in the metallurgical industry, in particular to a cutting slag collecting device for a continuous casting machine. Background Art

[0002] The collection of cutting slag generated by the flame cutting machine when cutting the steel billet online during the continuous production of the billet continuous casting machine in the steel plant was originally done by using a herringbone concrete slope in the area below the flame cutting machine. Two rows of nozzles facing the slopes on both sides were installed on the top of the slope. The falling cutting slag was flushed into the collection pool at the bottom of the slope by continuous water spraying, and then grabbed from the pool with a grab bucket. The main problems of this method are: first, cutting slag often accumulates on the slope, which is difficult to clean up after the slope accumulates slag. It can only be cleaned manually and requires multiple people to participate at the same time. The working environment is harsh and dangerous. Cleaning personnel are prone to slipping from the slope and falling into the collection pool, causing accidents.

[0003] Secondly, there is a blind spot when grabbing the cutting slag in the collection pool. It cannot be cleaned up normally and accumulates, causing blockage of the drain outlet. It can only be cleaned manually when the downtime is long. Utility Model Content
