Wall thickness and high temperature on-line measurement system for hot-rolled steel pipe

Abstract

The invention discloses a wall thickness and high temperature on-line measurement system for a hot-rolled steel pipe. The monitoring terminal is connected with the multi-channel ultrasonic monitoring module and the electrical control module through the communication module, the multi-channel ultrasonic monitoring module is connected with the probe set and the electrical control module, and the electrical control module is connected with the cooling module, the steel pipe movement stabilizing module, the sensor module and the steel pipe follow-up module. The cooling module is respectively connected with the steel pipe follow-up module and the probe group; the multi-channel ultrasonic monitoring module, the electrical control module, the cooling module and the communication module are mounted in a control cabinet, and a probe group is mounted in the steel pipe follow-up module; the control cabinet, the steel pipe movement stabilizing module, the sensor module and the steel pipe follow-up module are installed on a hot rolling production line. According to the invention, automatic online measurement of the wall thickness of the hot-rolled steel pipe is realized, the technical blank of online detection of the hot-rolled steel pipe is filled, the operation complexity is reduced, the detection timeliness is improved, and data support is provided for production automation, digitization and intellectualization.

Description

technical field [0001] The invention relates to an online steel pipe wall thickness measurement system in the field of hot-rolled steel pipe detection and monitoring, in particular to a hot-rolled steel pipe wall thickness and high temperature online measurement system. Background technique [0002] Due to the high temperature of the steel pipe during the hot rolling process (about 800 to 1200 degrees Celsius), the harsh production environment conditions (high temperature, metal dust, vibration, etc.), there is currently no long-term stable operation of the hot-rolled steel pipe wall thickness online detection or monitoring systems. At present, the detection method of hot-rolled steel pipes is mainly off-line (off-line) detection, that is, the steel pipes that have been cooled on the cooling bed for several hours are detected by tools such as mechanical measuring tools or ultrasonic testing equipment. The operation of offline detection is complicated, and the accuracy and r...
