Opis
Parametry techniczne
advantage:
(1) It can ensure the control of the temperature of the atmosphere in the furnace;
(2) Electric radiant tube heaters have a strong heating capacity and high efficiency;
(3) Save heat-resistant steel.
(4) Temperature control, installation, and maintenance are more convenient, and it is easy to seal;
(5) Since there is no muffle tank in the furnace, the furnace volume is enlarged and the production capacity is improved;
Cechy:
1. The electric heating alloy materials used in electric radiant tube heaters should have high resistivity and high electric heat conversion rate. Since the electric radiant tube heaters are placed in the casing, the heat transfer process is different from the general exposed electric heating element. The heat shield is large, and the temperature of the element is controlled during the heating process. Dlatego, when selecting materials, it is necessary to analyze the furnace temperature, temperature, and atmosphere in the furnace, and select the correct heating material.
2. It is made of seamless cold-drawn heat-resistant steel pipes made of excellent raw materials. It is suitable for working in high temperature, low oxygen partial pressure and an environment containing S and C.
3. The inner core adopts resistance wire U-shaped axial arrangement end welding method
4. The resistance wire and the ceramic frame are basically unshielded, and the temperature difference between the resistance wire and the furnace is small
parameter:
(1) Basic data required for calculation
(A): Use temperature t (℃)
(B): Heating electric power P (W)
(C): Component operating voltage U (V)
(D): Length of heating zone L (m)
(2) According to the basic data, combined with the working conditions of the electric heating element, determine the electric heating used
(3) According to the determined electric heating, refer to the known data and check the attached table to obtain the resistance temperature correction
