Heat transfer process: Switch on the power supply -- the current passes through the heating body -- the heat end of the heating body heats up -- the surface temperature of the heating body is high -- the substance closest to the heating body is heated -- the substance in the furnace is heated (air)-- the temperature in the furnace is increased -- the thermocouple is heated -- the thermocouple converts the heat signal into an electrical signal through the compensation wire to the temperature control meter -- the instrument displays the temperature and Temperature control - Through the constant temperature process, the temperature in the furnace reaches thermal balance.
The maximum temperature in the furnace is generally 100-200℃ lower than the maximum temperature of the heating body, and the use temperature in the furnace is appropriate to be 100℃ lower than the maximum temperature.
