Continuous casting cutting slag cleaning method and slag cleaning device thereof

Abstract

The invention discloses a continuous casting cutting slag cleaning method and a slag cleaning device thereof, which have the advantages that the simplicity is realized, the implementation is easy, the structure is simple, the installation and the use are convenient, and the slag cleaning effect is good. In the method, a blowing nozzle is arranged on a plane intersected with or vertical to the cutting surface, and ash at a cutting seam part is cleared by air through the blowing nozzle. The slag cleaning device comprises the blowing nozzle arranged on the plane vertical to the direction of a cutting nozzle through a U-shaped bent wall, and in addition, the blowing nozzle and the cutting nozzle are arranged at two opposite sides of billet steel.

Description

technical field [0001] The invention relates to a steelmaking continuous casting cutting device, in particular to a continuous casting cutting slag cleaning method and a slag cleaning device thereof. Background technique [0002] In steelmaking and continuous casting production, cutting speed and reliability are important factors to improve the cutting production efficiency of steelmaking and continuous casting. However, in today's increasingly tense energy environment, cutting quality affects both cutting speed and cutting reliability to varying degrees. , and more importantly, it also has a great impact on the consumption of cutting gas. The cutting quality is poor, the cutting loss is high, the gas consumption is large, and the cutting loss is naturally large, which requires the cutting tool to have a smooth cutting surface and slag hanging. However, no matter what kind of cutting tools, there is inevitably the problem of dross, and dross will cause edge phenomenon on the...

[0002] In steelmaking and continuous casting production, cutting speed and reliability are important factors to improve the cutting production efficiency of steelmaking and continuous casting. However, in today's increasingly tense energy environment, cutting quality affects both cutting speed and cutting reliability to varying degrees. , and more importantly, it also has a great impact on the consumption of cutting gas. The cutting quality is poor, the cutting loss is high, the gas consumption is large, and the cutting loss is naturally large, which requires the cutting tool to have a smooth cutting surface and slag hanging. However, no matter what kind of cutting tools, there is inevitably the problem of dross, and dross will cause edge phenomenon on the cutting surface, affect cutting speed, increase cutting gas consumption, increase Cutting damage, when severe, the slag sticks to the cutting nozzle and causes blockage, resulting in tempering, and the cutting nozzle is easily damaged
