Embodiment 1

[0037] like figure 1 As shown, a billet discharge system of a billet continuous casting machine in this embodiment includes a hot delivery roller table 1, a billet discharge cooling bed 1, a transition roller table 5, and a billet discharge cooling bed 2 7, and the hot delivery roller table 1 The outlet end is provided with an alignment pushing machine 2, and the direction of pushing steel of the alignment pushing machine 2 is perpendicular to the conveying direction of the hot-feeding roller table 1. 2. Push the fixed-length cast slab to the billet cooling bed-4, and the conveying direction of the billet cooling bed-4 is consistent with the steel pushing direction of the steel pushing machine 2; the transition roller table 5 is arranged on the billet cooling bed-4 The outlet end, and the conveying direction of the transition roller table 5 is perpendicular to the conveying direction of the first billet cooling bed 4, and the transition roller table 5 is used to transfer the f...

Embodiment 2

[0046] The billet discharge control method of the billet continuous casting machine billet discharge system in this embodiment adopts the billet continuous caster billet discharge system in Embodiment 1, utilizes infrared cluster automatic chain control, and implements according to the following process:

[0047] S1. The hot delivery roller table 1 transports the slab to the front end of the lifting baffle 3. An infrared camera is installed at the end of the lifting baffle 3 to monitor the deceleration of the slab running to the lifting baffle 3. 1, slab quantity measurement, slab in place stop signal, a total of three signals; when the infrared camera measures the slab quantity, it sends a stroke signal to the linear sensor built in the hydraulic cylinder of the alignment pusher 2, and the alignment pusher 2 pushes the slab to the The billet cooling bed-4 puts steel on the position, then returns to the original position and sends a signal to the billet cooling bed-4, the bille...

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...
