This paper mainly describes application of non-contact laser thickness gauge in steel plate rolling process, including workstation site thickness measurement, data collection, information analysis and integration with ERP system, as well as problems may arise during applications and sustainable development in the future. Through the system development to realize traditional steel plate rolling industry information planning, paperless operations, increase work efficiency, enhance product quality and zero defective products. Integrated design of steel plate thickness measurement and tachometer, to understand the pros and cons of output products right after steel plate rolling, and do product level classification immediately to assist enterprises to save manpower, time and loss cost of export defective products to the market, and eventually increase products competition and profits.

Ultrasonic Thickness

The thickness measurement and monitoring of all kinds of equipment and parts, especially making general investigations on the thickness of boiler, pressure vessel and pipelines regularly, monitoring their thinning after corrosion in the process of using, and ensuring the safety production have attracted more and more attention among the companies. Based on the thickness measurement principle of pulse reflection type ultrasonic, the measurement method of the steel plate thickness was studied, and AVR Atmega16 single chip microcomputer as control chip was used. The analysis and comparison of ultrasonic transmitting circuit, receiving circuit, amplifying circuit, LCD display circuit, keyboard circuit, communication circuit, counter 232 AVR Atmega16 line were also included. The performance of this system regarding the steel plate as sample was tested, and then the data and the causes of measurement error were presented.
