This paper introduces an automatic ultrasonic wall thickness measurement system, which adopts the way that the tube billet is partially immersed in the water during the measurement, applied in wall abrasive grinding of nuclear fuel encrust tube billet. Meanwhile, the main components of the measurement system, as well as their characters and functions, are addressed. What’s more, the analysis of the factors, which influencing the system stability and measuring reliability, are also conducted, coupling with the system stability and measuring reliability demonstration.
The work is devoted to the development of integrated thermostating subsystem of a high-precision system for measuring the thickness of hot metal rolling. The developed thermostatting subsystem includes active and passive modules, which ensured thermostability of the measuring modules at the level of 0.5 degrees in a hot metallurgical workshop. Thermal stabilization made it possible to ensure high accuracy in measuring the thickness of hot metal rolling in a hot metallurgical production workshop.
