Abstract
The invention discloses a casting blank cutting positioning method and a system. The method comprises the steps of: receiving a drawing roller rotating signal of a withdrawal and straightening machine; determining an operation length of a casting blank according to the drawing roller rotating signal; generating and sending a head blank cutting command to a cutting device so as to control the cutting device to perform the head blank cutting for the casting blank when the operation length is equal to a sum of a basic length and a preset head blank length, wherein the basic length is a distance from a liquid level of a crystallizer to an original position of a cutting car; zeroing the operation length; and generating and sending a cutting command to the cutting device so as to control the cutting device to perform the finished-product cutting for the casting blank when the operation length reaches a preset finished-product cutting length. The casting blank cutting positioning method and system, provided by the invention, are used for solving the technical problems of low precision and high equipment maintenance cost in a casting blank cutting positioning method of the prior art, and realize the technical effects of improving the cutting positioning precision and reducing the equipment maintenance cost.
Description
technical field [0001] The invention relates to the technical field of iron and steel smelting, in particular to a billet cutting and positioning method and system. Background technique [0002] At present, the billet cutting and sizing system adopts infrared tracking and automatic sizing, that is, the infrared camera is used to track the running length of the high-temperature billet to cut the billet. [0003] However, adopting infrared tracking automatic sizing has the following technical problems: [0004] 1. Light changes in the camera area have a great influence on the accuracy of infrared rays. [0005] 2. Since the lens of the camera must be wiped regularly to keep it clean, it is very easy to cause changes in the camera angle to affect the accuracy of the sizing. [0006] 3. The image signal transmission line of the camera is extremely susceptible to interference from external signals, causing confusion in the sizing system. [0007] 4. Due to the long running tim...
