Mainly introduces the application of induction heating and infrared temperature measurement in roulette heating test, and changes the traditional long-term resistance wire radiation heating method in roulette strength test so as to improve the heating speed, heating uniformity, power adjustable, control. Improved long-term use of the wheel strength test of the test piece welding thermocouple contact temperature measurement method, which can achieve the strength of titanium alloy wheel test temperature, slip ring can be freed of electrical appliances and Freon cooling system, saving Thermocouple welding work hours, improve the test efficiency and temperature reliability, improve the measurement accuracy. A special IF induction heater can achieve on-board temperature distribution gradient
