Automatic scarfing device for flame cutting of continuous casting

Abstract

The invention discloses an automatic scarfing device for flame cutting of a continuous casting. The automatic scarfing device consists of four parts, namely an electric control unit A, a compressed air unit B, an automatic scarfing gun unit C and a cooling water unit D. The automatic scarfing device and a matched flame cutting device are ideal equipment for fixed size cutting of steel wires or steel blasts rolled by a continuous casting machine in a steel factory; and the technical performance exceeds the national standard, the industrial standard and the process rule requirement of users. The finished product ratio of the steel blast made by fixed size cutting is over 99 percent; oxygen, fuel gas and compressed air for cutting are all saved by over 85 percent; a cutting gap is reduced from the conventional 8 millimeters to about 2 millimeters; the residues can be cleared away, so the problem that the residues may be suspended during flame cutting of the continuous casting can be solved; and the automatic scarfing device has a very good popularization value, is applicable to industries of metallurgy, shipbuilding, petroleum, chemical engineering, metal structures and the like, and particularly used for quickly and continuously cutting and scarfing a metal material with the temperature less than or equal to 950 DEG C.

Description

technical field [0001] The invention belongs to the technical field of metal cutting, in particular to an automatic slag removal device for flame cutting. Background technique [0002] At present, in the cutting technology market at home and abroad, despite the continuous development of cutting technology, the problem of slag hanging at the flame cutting edge of continuous casting billet is a long-standing and difficult problem that has not been solved for many years. Contents of the invention [0003] The purpose of the present invention is to provide a new type of automatic slag removal device which can remove the slag hanging from the cutting edge at the same time as the flame cutting. [0004] The present invention is composed of an electric control unit A, a compressed air unit B, an automatic slag cleaning gun unit C and a cooling water unit D. The electrical control unit A is electrically connected to the solenoid valve in the compressed air unit B, the air outlet ...
