Detailed analysis of the structure and some driving components of the temperature control instrument for a box type electric furnace

Using thermocouple temperature sensors and photoelectric pyrometers, electric furnace temperature measuring instruments, thermocouples can directly provide a touch based measurement experience. If the temperature is relatively high, radiation type photoelectric thermometers must be used for non-contact measurement to achieve more accurate results. The temperature signals sent by temperature sensors and transmitters will be displayed on the temperature control instrument. After comparing the temperature value with the set value, the output temperature control M signal source makes the temperature control of the resistance furnace more accurate. In cases where the control accuracy requirement is not high, an analog position control thermometer can also be used, usually displaying a large number of temperature control instrument values in digital form.
Auxiliary circuits refer to circuits other than the main heating circuit, which include auxiliary devices, safety interlock protection for working status indication, etc., which are all necessary. The heating driving component plays a power amplification role, converting changes in temperature control signals into changes in heating power, heating the electric heating element, and achieving the goal of changing the furnace temperature. One of the main reasons for affecting the temperature control method is the use of heating drive components, such as solid-state relays, contactors, thyristor regulators, and transformers. Electric heating components are the components that convert electrical energy into thermal energy, mainly non-metallic, metal alloys, and pure metals.
The heating power of a box furnace determines the heating speed and the temperature of the furnace. If you want to change the heating power, common methods include electric furnace transformer control and thyristor regulator. Its purpose and temperature are necessary and decisive. In terms of temperature control of resistance furnaces, the deviation phenomenon of actual temperature compared to the set temperature can change the corresponding heating power of the electric furnace to a certain extent, so that the temperature does not differ significantly between the set value range.
The temperature control process of a box type resistance furnace is mostly the same regardless of which method is used. Overall, the temperature controller, temperature measurement, electric heating elements, heating driving components, and auxiliary circuit materials can all be better used for heat treatment work.
