Why is the role of high-temperature electric furnaces in industry becoming more and more important?

Part of the heat energy converted from electric energy consumed by the high-temperature electric furnace is lost to the space due to various factors such as the construction materials and heat transfer of the electric furnace, and the other part is used to heat the workpiece in the furnace. The first part becomes the power loss of the electric furnace. Part of it forms the effective power. In the electric control circuit of the resistance furnace, the commonly used relay amplifies the control signal output by the instrument to directly drive the smaller current actuator, or transmit the signal to other related control components.

High-temperature electric furnaces play an increasingly important role in industrial production, which is mainly determined by their working principle. High-temperature electric furnaces use electric energy as energy source, and heat the furnace after connecting with heating elements to heat the workpieces in the furnace. Compared with the traditional heating furnace, the high-temperature electric furnace has a faster heating speed. The temperature control system adopts a computer system, and the control accuracy is higher, which can meet the increasing demand of people. The high temperature electric furnace has good insulation performance, heat is not easy to dissipate, high thermal efficiency, and strong anti-interference ability. When the high temperature electric furnace is working, the temperature of the furnace wall is close to room temperature. There is no dust and high temperature environment troubles, which greatly improves the working environment of the operators. The important thing is that compared with traditional heating furnaces, high-temperature electric furnaces have less pollution and are more suitable for environmental protection standards. The high-temperature electric furnace is simple and convenient to operate, the design is simpler, and the floor space is small.

There are several common forms of common adjustment laws for automatic temperature control of high-temperature electric furnaces, such as two-position, three-position, share, and share integral differential. Furnace temperature control is such a reaction conditioning process, comparing the actual furnace temperature and the need for high-temperature electric furnace temperature to obtain the error, after dealing with the error, the control signal is obtained to adjust the thermal power of the resistance furnace, and then the furnace temperature control is completed. The high-temperature electric furnace is composed of two conductors with different components connected at both ends to a synthetic circuit. Its working principle is to use the temperature difference at the junction to form an electromotive force. The high temperature electric furnace thermocouple uses the different temperature values ​​of the junction point and the principle of the electromotive force generated in the loop to measure the temperature. The size and location of the effective working area of ​​the box furnace is determined by the position distribution of the thermocouple in the furnace of the high-temperature electric furnace.
