Width Measuring System for Slab for Plate Steel

Overview
The WGS-L200 Laser Slab/ Plate Steel Width Measuring System adopts the principle of double laser triangulation reflection to process the online measurement of the steel plate on the roller bed, and combines the high-speed digital signal processing technology and programming software to process the signal correspondingly, and displays the relevant data and measurement curve, so as to realize the accurate control for steelmaking process during the production.
The WGS-L200 Laser Slab/Plate Steel Width Measuring System is mainly composed of computing processing software and hardware systems such as testing equipment, computing equipment. The hardware system consists of 2 sets of laser triangulation rangefinding system, on-site signal acquisition and transmission system, operation unit, host analysis and control alarm system, etc. The software of WGS-L200 laser slab/ plate steel width measuring system mainly includes data acquisition and analysis, alarm software and data visualization operation software in the host system. The data analysis system analyzes and converts the data transmitted by the signal acquisition and analysis system into the visual data of the main control room, and completes the width measurement monitoring work in the slab production operation through the set alarm threshold.
