    9 , steel induction furnace with closed cooling tower for cooling, energy saving. 5. How to choose and choose steel tube induction heating furnace? Mainly to consider from several aspects:

    1. The shape and size of the heated workpiece

      For large workpieces, round bars, and solid materials, steel tube induction heating furnaces with relatively high power and low frequency should be used; for small workpieces, tubes, plates, gears, etc., steel tube induction heating furnaces with relatively low power and high frequency should be used.

    2. The depth and area that need to be heated

      The heating depth is deep, the area is large, and the overall heating should be a steel tube induction heating furnace with high power and low frequency; the heating depth is shallow, the area is small, and local heating is used, and the relatively low power and high frequency steel tube induction heating furnace should be selected.

    3. Required heating rate

      If the heating speed is fast, a steel tube induction heating furnace with relatively large power and relatively high frequency should be used.

    4. Continuous working hours of equipment

      The continuous working time is long, and the steel tube induction heating furnace with a slightly larger power is relatively used.

    5. The connection distance between the sensing component and the equipment

      The connection is long, and even water-cooled cable connection is required, so a relatively high-power intermediate frequency induction heating furnace should be used.

    6. Process requirements

      Generally speaking, for processes such as quenching and welding, you can choose a lower power and a higher frequency; for annealing and tempering processes, choose a higher relative power and a lower frequency; red punching, hot forging, smelting, etc., need If the heating effect is good, the power should be larger and the frequency should be lower.

    7. The material of the workpiece

      Among the metal materials, the higher melting point is relatively large, the lower melting point is relatively small; the lower resistivity is higher, and the higher resistivity is lower. 

    6. What parameters are required for the selection of steel tube induction heating furnace?

    The selection of steel tube induction heating furnace generally requires the following parameters:

    First: the shape of the workpiece to be heated, the outer dimensions, and the weight of the workpiece to be heated.

    Second: the material quality of the workpiece to be heated (generally induction heating, only for the metal conductor material).

    Third: the time required for the heating of the heated workpiece to the target temperature, and the target temperature.

    Once the above three points are clear, the steel tube induction heating furnace can be selected including matching power.

    Seven, what are the characteristics of the furnace body structure of the steel tube induction heating furnace?

    1. Furnace structure: The heating furnace of our company is designed as an integral quick-change type. When the furnace body is changed for different heating workpieces, rapid replacement can be realized.

    2. Furnace lining: The furnace lining adopts silicon carbide or integral knotting method, and the service temperature is above 1450.

    3. Protection: automatic shutdown when the water temperature exceeds 65.

    4. Induction furnace water-cooled track: A water-cooled track is installed on the lining of the induction furnace.

    8. How to calculate the power of steel tube induction heating furnace?

      P=(0.168×200×693)/(0.24×0.6×145)=1029KW where: 0.168average specific heat of ferrous metal; 2080workpiece mass (Kg); 200workpiece heating temperature rise; 0.24Work-heat equivalent; 0.6average efficiency (in this example, 0.6, generally 0.50.65, and special-shaped sensors are lower, 0.4); 145working cycle (seconds)

    Based on the above calculations, 1KHz induction heating equipment with a rated power of 1500KW can be configured to meet the needs.

    9. How to choose the power frequency of steel tube induction heating furnace?

    The selection of power frequency follows the principle of optimal heating efficiency and temperature uniformity (core-surface temperature difference). The higher the frequency, the higher the heating efficiency, but too high a frequency will easily cause the surface of the workpiece to burn. According to our experience, choose the frequency 2500KHZ , Can get the best heating effect, and will not cause the workpiece temperature to overheat.
