Cutting method and system for improving cutting precision of slab casting machine

Abstract

The embodiment of the invention discloses a cutting method and system for improving the cutting precision of a slab casting machine. The method comprises the steps that slab cutting calibration coordinates are preset and stored in a database, slab head lower edge coordinates are obtained in real time and compared with the slab cutting calibration coordinates, an instruction signal is sent to a cutting machine if the slab head lower edge coordinates are the same as the slab cutting calibration coordinates, and the cutting machine receives the instruction signal and then cuts a slab. The lower edge of the head of the slab is detected through a camera, the coordinates of the lower edge are obtained in real time, and therefore the head position of the slab can be tracked accurately; when the coordinates of the lower edge are the same as the preset slab cutting calibration coordinates, the cutting machine is controlled to cut the slab. By the adoption of the method, the slab cutting precision of the slab casting machine is greatly improved.

Description

technical field [0001] The invention relates to the technical field of continuous casting slabs, in particular to a cutting method and system for improving the cutting precision of a slab continuous casting machine. Background technique [0002] Continuous slab casting is a smelting technology that continuously casts slabs through slab continuous casting machines, such as figure 1 As shown, the slab continuous casting machine includes a steel casting equipment 1 and a roller table 2 . After the steel casting equipment 1 casts the slab, it is transported to the downstream process through the roller table 2. During the transportation of the slab, according to the order plan, the slab needs to be cut by the cutting system. [0003] Such as figure 2 It is a schematic diagram of the installation of the cutting system. The cutting machine 3 is fixed on one side of the roller table 2. The cutting machine 3 can move freely along the roller table 2. The cutting machine 3 is provid...
