Embodiment Construction

[0014] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0015] As shown in the figure, in order to solve the wedge-shaped billet cutting problem when the continuous casting crystallizer is adjusted online, a support beam 2 is set on the large traverse 4 bracket, and a wedge-shaped billet cutting machine 1 is symmetrically installed on the cutting gun. on the beam of the machine, and is driven by the motor to move back and forth on the track of the support beam 2; when the continuous casting line width adjustment produces a wedge-shaped billet, the lifting device 11 with large lateral movement rises, and the wedge-shaped cast billet 10 moves out from the conveying roller table 12 and falls on the On the slab trolley 13, the large traversing traction device 5 will move the slab trolley 13 to move the wedge-shaped casting slab 10 to the storage rack 7, and the large traversing elevating device 11 will be starte...

Abstract

The invention discloses an on-line cutting method and an on-line cutting device for a wedged casting blank, which are applied to cutting wedged blanks when a continuous casting crystallizer is adjusted in width on line. The method comprises: a strut beam is arranged on a bracing frame on a large shift, and a wedged blank cutting machine is installed on the strut beam; the large shift moves the wedged casting blank to a storage frame of the large shift from a conveying roller way, and the position of the cutting machine is adjusted to cut the wedged casting blank; the wedged blank cut from the wedged casting blank falls onto a receiving groove trolley below the large shift to be transported out; and the qualified casting blank after cut is subjected to rolling procedure through being transported back the conveying roller way by the large shift. The cutting device is arranged on a large beam, the wedged blank can be cut on line and can be timely returned to the casting plan; therefore, the method and the device avoid quality degradation caused by cutting the wedged blank off line, can save secondary heating when rolling the casting blank, reduce energy consumption, and simultaneously solve the problem of cutting precision which can not be ensured by manual cutting, lighten working strength at a large degree, and ensure safe production.

Description

technical field [0001] The invention belongs to the technical field of metallurgical continuous casting and rolling, and relates to a process for processing slabs, in particular to an online cutting method and equipment for processing wedge-shaped slabs produced during online width adjustment of continuous casting crystallizers. Background technique [0002] Continuous casting and rolling production has been recognized and popularized by the metallurgical industry for its fast production speed and high product quality. However, when the continuous casting mold is adjusted online, a wedge-shaped billet will be produced. The processing method of billet is to cut it off-line manually, which will cause the following problems. First, the cast billet after off-line cutting cannot be continuously rolled or heated and rolled according to the casting plan. , affecting the execution rate of the contract; second, the slab must be cooled and then cut after being processed off-line, and ...
