Online real-time measuring system and calculating method for width and length of casting blank

Abstract

The invention relates to an online real-time measuring system and a calculating method for width and length of a casting blank. The measuring system comprises a data acquisition and processing system,a casting blank roller way conveying system and a casting blank specification and dimension data processing system, wherein the data acquisition and processing system comprises a serial port-to-DP network transmission module, an analog quantity input module, a left side width measuring instrument, a right side width measuring instrument, a length range finder and an infrared thermometer; and thecasting blank roller way conveying system comprises a roller way variable frequency control system, a rotary table roller way driving motor and a deburring machine roller way driving motor. The calculating method is used for calculating the measuring width and the measuring length of the casting blank, performing compensation calculation on the width and the length of the casting blank according to casting blank temperature data acquired in real time, and restoring the cold-state width and the cold-state length of the casting blank at the temperature of 0 DEG C according to the online real-time measuring system and the calculating method disclosed by the invention, abnormal information of the width and the length of the casting blank can be found in time, the monitoring precision is high,the potential safety hazard of high-temperature injury during measuring operation of an operator is avoided, and the labor intensity of the operator is reduced.

Description

technical field [0001] This patent application belongs to the technical field of on-line measurement of slab specifications, and more specifically relates to an online real-time measurement system and calculation method for the width and length of a slab. Background technique [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 unsafe and health hazards caused by hot slab burning during manual measurement, and safety and quality accidents are prone to occur. . Therefore, according to the accuracy requirements of the width and length of the slab and the operating characteristics of the field equipment, an online real-time measurement system and method for the width and length of the slab are designed. The detection information of the on-site instruments is collected, and the f...
