Embodiment Construction

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

[0015] As shown in the figure, in order to solve the problem of wedge-shaped billet cutting when the continuous casting mold is adjusted online, the supporting beam 2 is arranged on the large traverse 4 bracket, and the wedge-shaped billet cutting machine 1 flame cutting gun is symmetrically installed in the cutting On the machine beam, it is driven by the motor to move back and forth on the support beam 2 track; when the continuous casting on-line width adjustment produces a wedge-shaped billet, the large-transverse lifting device 11 rises, and the wedge-shaped cast billet 10 moves out of the conveyor roller 12 and falls on On the billet transport trolley 13, the large traverse traction device 5 moves the billet transport trolley 13 to the storage rack 7, and the large transversal lifting device 11 is activated to lower it, and the wedge-shaped cast slab 10 falls ...

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 thewedged 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 slab processing technology, in particular to an online cutting method and equipment for wedge-shaped cast slabs produced when the continuous casting mold is adjusted online. 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, it will produce a wedge-shaped casting billet. At present, due to the online mold widening, the wedge-shaped casting The processing method of the billet is to manually cut it after it is off the line. The off-line manual cutting will cause the following problems. One is that the cast slab after the off-line cutting cannot be continuously rolled or furnace-heated rolling with the casting plan. , Affecting the contract implement...
