Billet discharge system of square billet continuous casting machine and billet discharge control method thereof

Abstract

The invention discloses a billet discharge system of a square billet continuous casting machine and a billet discharge control method thereof, and belongs to the field of steelmaking continuous casting. The billet discharge system comprises a hot delivery roller way, a first billet discharge cooling bed, a transition roller way and a second billet discharge cooling bed. The outlet end of the hot delivery roller way is provided with an aligning and steel pushing steel machine, the steel pushing direction of the aligning and steel pushing machine is perpendicular to the delivery direction of thehot delivery roller way, the aligning and steel pushing machine pushes a fixed-sized casting billet onto the first billet discharge cooling bed, and the conveying direction of the first billet discharge cooling bed is consistent with the steel pushing direction of the aligning and steel pushing machine; and the transition roller way is arranged at the outlet end of the first billet discharge cooling bed, the conveying direction of the transition roller way is perpendicular to the conveying direction of the first billet discharge cooling bed, the conveying direction of the second billet discharge cooling bed is perpendicular to the conveying direction of the transition roller way, and a collecting rack is arranged at the outlet end of the second billet discharge cooling bed. The system solves the problem that in the prior art, due to the limitation of production space, a conventional billet discharge system of the square billet continuous casting machine cannot be arranged normally, and process production requirements and automation control can be met.

Description

technical field [0001] The invention relates to the technical field of steelmaking and continuous casting, and more specifically, to a billet discharge system of a billet continuous caster and a billet discharge control method thereof. Background technique [0002] The No. 1 Steel Rolling General Plant of Maanshan Iron and Steel Co., Ltd. originally had 2 sets of molten iron pretreatment devices, 3 sets of 120t top-bottom combined blowing converters, 3 sets of LF ladle refining furnaces, 1 set of VD vacuum degassing device, and 1 set of RH vacuum refining device. The casting system is equipped with 2 sets of CSP continuous casting and rolling, with an annual output of 2 million tons, a single-strand slab continuous caster with an annual output of 1.2 million tons, and a 3-machine, 3-strand round billet continuous caster with an annual output of 300,000 tons t. The total output is around 3.5 million tons. [0003] In the fierce market competition, in order to focus on impro...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to overcome the problems in the prior art that the billet discharge system of the traditional billet continuous casting machine cannot be arranged normally and the length of the step cooling bed cannot meet the process requirements due to the limitation of the production space in the prior art, and proposes to provide a billet continuous casting machine The blanking system and its blanking control method, the control method of the present invention is used to arrange the blanking system correspondingly, which can meet the requirements of process production and automatic control, greatly reduce labor costs, and avoid the risk of operational errors due to no manual operation probability, improving the cooperation efficiency between devices
