This equipment is designed according to the production process requirements of steam turbines and mainly consists of a temperature control and recording system for the furnace body (including furnace lining, furnace cover, heating elements, furnace power supply system, sealing device), a workpiece support wheel device and operating system, a measurement system, and a workpiece cooling and lubrication system. (This project is the responsibility of the purchaser) for the thermal stability test of the steam turbine when heated to the working temperature, to determine the deformation of the rotor at that temperature.
