Online Real-time Measurement System and Calculation Method of Slab Width and Length

Abstract

The invention relates to an online real-time measurement system and calculation method for the width and length of a slab. The measurement system includes a data collection and processing system, a slab roller conveying system, and a data processing system for slab specifications and sizes. The data collection and processing system includes a serial port to DP network. Transmission module, analog input module, left width measuring instrument, right width measuring instrument, length distance measuring instrument, infrared temperature measuring instrument; billet roller conveying system includes roller frequency conversion control system, turntable roller driving motor, The drive motor of the roller table of the burr machine; the calculation method is used to calculate the measured width and length of the slab. According to the temperature data of the slab collected in real time, the width and length of the slab are compensated and calculated, and the cold temperature of the slab at 0 degrees is restored. state width and length. The invention can timely find the abnormal information of the billet width and length data, has high monitoring precision, avoids the potential safety hazard of high temperature injury during the measurement operation of the operator, and reduces the labor intensity of the operator.

Description

Technical field [0001] This patent application belongs to the field measurement technology of the slab. More specifically, it is related to a fact that a width and length online real-time measurement system and a calculation method are used. Background technique [0002] At present, the slab joint measures are measured, and the field personnel need to measure the on-site person, the measurement accuracy is low, and there is a hot blazing insecurity and health damage when manual measurement. It is prone to safety and quality accidents. . Therefore, according to the width and length accuracy requirements of the slab and the operating characteristics of the field equipment, a factor system and method are designed, and the method is used to enter the measurement state in different periods by controlling the roller system, and timely Collect the detection information of the field instrument, and finally calculate the width and length information of the slab. Inventive content [0003...

AI Technical Summary

Problems solved by technology

[0002] At present, the fixed-length measurement of the slab continuous casting machine and the fire-cutting machine require on-site personnel to measure with a box ruler or a board ruler, and the measurement accuracy is low. There are hidden dangers of hot slab roasting and health hazards during manual measurement, and safety and quality accidents are prone to occur.
