A Method for On-Line Continuous Correction of Infrared Camera Sizing Error in Continuous Casting

Abstract

The invention discloses an online continuous correction method for continuous casting infrared camera sizing error, which relates to the technical field of steelmaking continuous casting, and solves the problem of poor precision. The technical point is: a method for continuous casting infrared camera sizing error on-line continuous correction, including the following steps: the infrared camera performs the first pass of slab sizing cutting, and calculates the error ΔX; measures the vertical distance between the infrared camera and the slab; For the distance H, take the scale values ​​at the two cutting positions and record them as L 末 and L 1 ; After tanα is changed by 1 unit value, the scale value of the second point is recorded as L 2 , the actual cutting position of the second point is recorded as L 2真 =L 2 ±X 1 ±ΔX / Δtanα. According to the actual cutting length of the continuous casting slab, the error correction value is dynamically adjusted online to make the measured value closer to the actual cut-to-length value, which improves the sizing accuracy of the continuous casting slab and provides important support for precise control of the length and weight of the continuous casting slab.

Description

A method of continuous casting infrared camera fixed-length error online continuous correction technical field The present invention relates to steelmaking continuous casting technical field, particularly a kind of continuous casting infrared camera fixed-length error on-line continuous Corrected method. Background technique [0002] In the technical field of steelmaking and continuous casting, the sizing accuracy of the continuous casting billet is very important. The control accuracy of the continuous casting billet length is directly Affecting the yield of the casting billet, if the cut billet is too long, it will cause a lot of waste. Too short will not roll out the desired finished bar or tube. Infrared camera continuous casting billet fixed-length measuring technology is now the However, in practical applications, due to the limited number of infrared cameras and the viewing angle deviation from the location, so The length deviation of the cut billet that is ...

AI Technical Summary

Problems solved by technology

The control accuracy of continuous casting slab length directly affects the yield of casting slab. If the cut continuous casting slab is too long, it will cause a lot of waste. If the cut slab is too short, the required finished product cannot be rolled. Rod or Tube

Infrared camera continuous casting slab length measurement technology is the mainstream technology for slab sizing at present. However, in practical applications, due to the limited number of infrared camera length measurement and the angle of view deviation from the positioning position, this technology guides the flame cutting machine to complete There is still a deviation in the length of the cut slab that exceeds the allowable range, and the general error needs to be adjusted manually, and the accuracy is poor
