Efficient casting blank bur removing method and device

Abstract

The invention relates to an efficient casting blank bur removing method and device. The device is arranged at the back of a flame cutting machine. The device comprises a big trolley, a small trolley, a position detecting mechanism and a temperature detecting mechanism, wherein the position detecting mechanism is used for detecting the actual positions of the front end and the rear end of a casting blank; the position detecting mechanism and the temperature detecting mechanism are fixed to a casting machine base at the lower part of a casting blank conveying roller bed; the temperature detecting mechanism is used for detecting the surface temperature of the casting blank; the big trolley is driven by a big trolley driving mechanism to reciprocate along a big trolley guide rail; the small trolley is loaded by the big trolley and is driven by a small trolley driving mechanism to reciprocate along a small trolley track; and a front end cleaning gun and a rear end cleaning gun are loaded on the small trolley and are correspondingly used for preheating and cleaning the front end and the rear end of the casting blank. The device has the advantages that the burrs are cleaned through flame, so that the burrs at the end part of the casting blank can be removed by 100%. With the adoption of the method, the influence of casting blank bur cutting on the casting blank quality is decreased to be zero, and the influence on the roller surface is decreased to be zero.

Description

technical field [0001] The invention belongs to the field of metallurgical continuous casting flame cleaning, and in particular relates to a method and device for efficiently removing burrs from casting slabs. Background technique [0002] For the continuous casting slab cut to length by the flame cutting machine, the oxidized steel slag formed after the cooling of the molten metal flow remains under the cut, which is called "burr". The hardness of the burrs is very high, and they will be irregularly embedded in the slab during the subsequent rolling process, causing surface defects such as scarring or pitting on the slab, seriously affecting product quality, and causing damage to the conveyor roll and roll. In order to solve this problem, a mechanical deburring device is generally installed in the conveying roller area, and the burrs on the lower part of the end face of the billet are removed by beating or scraping. This method cannot guarantee 100% deburring, and the resid...
