Abstract

The invention relates to a casting blank positioning control system for a continuous casting machine. The casting blank positioning control system comprises infrared cameras (4), a special picture processing machine (1), a relay tank (2) and a blank discharging PLC (3) which are sequentially electrically connected, wherein the infrared cameras (4) are arranged outside inlets and outlets of blank discharging roller ways (5), and the blank discharging PLC (3) can be used for controlling the starting and stopping of the blank discharging roller ways (5). A control method comprises the following steps: (a) collecting a casting blank image by virtue of the infrared cameras (4); (b) analyzing the image by virtue of an image analysis module; (c) carrying out image digitization and anti-interference treatment by virtue of an image digitization and anti-interference treatment module; (d) inputting a limiting signal into the blank discharging PLC (3) by a signal limiting module through the relaytank (2); and (e) controlling the starting and stopping of different blank discharging roller ways (5) by virtue of the blank discharging PLC (3). The system can be applied to high-temperature severeenvironments and is long in service life, and the positioning is accurate; and by utilizing multi-point limiting monitoring manner, the system can meet the production requirements, the labor intensity can be relieved, and the production cost can be lowered.

Description

technical field [0001] The invention relates to a billet positioning control system and method for a continuous casting machine, and belongs to the technical field of control systems. Background technique [0002] The billet roller table of the continuous casting machine is generally composed of multiple sets of roller tables, and each group of roller table is composed of multiple rollers. According to the hot and cold metal detector, the signal roller or the proximity switch, the different positions of the hot casting billet on the billet roller table are detected. , Start different roller table groups to run respectively. Especially in the billet continuous casting machine, due to the high casting speed and small runner spacing, the temperature of the hot casting billet on the billet roller table is very high, about 600-800 °C. The positioning device in the prior art mainly includes an image processing computer, an industrial camera, a camera controller module, an image p...
