Problems solved by technology

After cutting the continuous casting billet, especially the billet continuous casting billet, after the cutting machine cuts it vertically, there will be cutting tumors on the upper and lower surfaces of the continuous casting billet after cutting. Since the cutting method is vertical from top to bottom Cutting, oxidation slag adheres to the lower edge of the continuous casting slab section, forming cutting nodules, and this edge is the contact surface between the rolling mill roll and the billet in the next process. These cutting nodules not only affect the processing of the next process, but also increase Billet cutting head and tail cutting often bring objections to product quality, affecting the product quality and economic benefits of the enterprise

Embodiment Construction

[0011] The present invention will be further described through the embodiments below in conjunction with the accompanying drawings.

[0012] In the embodiment, the application of the present invention cuts off a 130×173mm square billet. Originally, the vertical cutting method was adopted. Due to the cutting lumps under the section of the billet, the billet in the steelmaking process is continuously cast for the cutting edge of the billet in the rolling process of the next process. Too much slag will cause a large number of head and tail cuts in the rolling process. In severe cases, the quality of the entire strip steel will be unqualified due to slag inclusions and pitting. Using the side cutting method of the present invention, the original cutting machine is slightly modified, and the flame cutting machine gun is changed to an "L" type cutting gun, which is convenient for side cutting, and the cutting position of the cutting gun is changed. The horizontal shift is changed to...

Abstract

A method for laterally cutting off the connection between conticast parts by flame features that the cutting torch is arranged at the lateral side of conticast parts and is moving up and down to separate the conticast parts from each other. Its advantage is no influence to the top and bottom surfaces of conticast parts.

Description

technical field [0001] The invention relates to a method for cutting continuous casting slabs in iron and steel smelting technology, in particular to a method for cutting continuous casting slabs with flames at the side of the continuous casting slabs. Background technique [0002] At present, in steelmaking production, people use flame cutting machine to cut the continuous casting slab. The method of flame cutting is to cut the continuous casting slab vertically, that is, the cutting gun is perpendicular to the upper surface of the continuous casting slab, and the upper surface of the continuous casting slab For cutting, the continuous casting slab is cut through the horizontal movement of the cutting gun, and the flame cutting gun can be fine-tuned left and right. After cutting the continuous casting billet, especially the billet continuous casting billet, after the cutting machine cuts it vertically, there will be cutting tumors on the upper and lower surfaces of the cont...
