Embodiment Construction

[0044] The present invention will be described in detail below in conjunction with the accompanying drawings, but it should be pointed out that the implementation of the present invention is not limited to the following embodiments.

[0045] See Figure 1-Figure 4 , a device for efficiently removing burrs from billets. The flame cutting machine is set at the rear of the sector of the continuous casting machine, and this device is set behind the flame cutting machine. The original mechanical deburring machine can be removed during actual transformation, and the replacement cost device, this device operates independently and does not take up additional space.

[0046] The specific structure of the device for efficiently removing burrs from casting slabs includes carts, trolleys, cart guide rails, trolley tracks, position detection mechanisms, temperature detection mechanisms, cart drive mechanisms, front-end cleaning guns, and rear-end cleaning guns; the position detection mecha...

Abstract

The invention relates to a method and device for efficiently removing burrs from a slab. The device is arranged behind a flame cutting machine and includes a cart, a trolley, a position detection mechanism, and a temperature detection mechanism; the position detection mechanism is used to detect the front and rear ends of the slab. The actual position, the position detection mechanism and the temperature detection mechanism are fixed on the casting machine foundation under the slab conveying roller table; the temperature detection mechanism is used to detect the surface temperature of the slab; the cart moves along the cart guide rail driven by the cart drive mechanism Reciprocating movement, the trolley carries a trolley, and the trolley can reciprocate along the trolley track under the drive of the trolley drive mechanism. The trolley carries the front cleaning gun and the rear cleaning gun, and the front and rear cleaning guns respectively preheat and clean the front and rear ends of the slab. clean up. The method has the advantages that the burr is cleaned by using the flame to realize 100% removal of the burr at the end of the billet. By adopting the method of the invention, the influence on the quality of the casting slab due to cutting the burr of the casting slab is reduced to zero, and the influence on the surface of the roll is reduced to 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...
