Three Strands Continuous Casting Non-contact Automatic Length Cutting System

Specifications

1. Working principle

The equipment uses dynamic image recognition technology, detects and displays the operation status of hot billet online.Through the camera next to roller collect images into computer, through acceleration module for analog video signal processing and A/D conversion into digital signal. The characteristics of image acquisition to achieve real-time, video input, stereo vision image sequence analysis, moving image display, camera synchronous switching, image processing and video signal synchronization, completely real time transmission and processing effect, meet the complex spot technical requirements.

2. System function

(1)The system adopts an advanced technology of picture-processor(non-contact) which can identify the length of hot billet, auto-control the shear of cutting hot billet. Moreover, it could test and show the running state and the speed of pull, at the same time it controls 3 strands casting blank.

(2)Changing length conveniently, and it can be stored for different length. Multi camera picture automatically switch.

(3)The monitor can real-time display the running state of hot billet and related parameters, such as: Each strand billet average casting speed, count and show the number of subsections of each strand, the total cutting root number and total yield of 3 strands.

(4)The operator keyboard or mouse can be used to change the various      control parameters, and be able to real-time adjust each strand of fixed length online.

(5)The length software possesses production and management functions, such as the counting function for cutting root.

(6)In normal circumstances(such as: cutting vehicle can automatically return to zero, flame cutting machine clamp rapidly, accurately without slipping), system identification error within ± 5mm, final cut error is less than ± 10mm .The system can adjust the error range, so that the error to a minimum. If cutting car can not automatically return to the original position after cutting every time, and the flame cutting machine has the phenomenon of clamp not tight,drag slip, It can be through adding a cutting vehicle positioning device to complete the length compensation, to achieve high precision cutting.

(7)Software can pre provide communication interface according to the practical need.

3.Signal output method

Signal is electric relay switch, each strand has two signals output, one is clamping signal and the other is cutting signal, amounting to 6 signals output.

4. Working environment

(1)  System and the camera normal working temperature: ≤ 70 °C.

(2)  Medium energy: ~ 220V power supply.

(3)  Typical camera installation requirements: monitoring the scope of the camera is no obstacle
