    1 ton fixed-point casting intermediate frequency melting furnace to hydrogenate milling process

    The milling workshop uses 1 ton of fixed-point casting intermediate frequency melting furnace for hydrogenation milling. The medium frequency furnace uses a power source different from the power frequency electric furnace. It is a 380V power frequency AC power input to the intermediate frequency power cabinet (the intermediate frequency power cabinet has overvoltage protection, overcurrent protection, if there is overvoltage or overcurrent, it will automatically stop alarm) In the intermediate frequency power cabinet, the power frequency AC power supply is rectified into single-phase DC power, and then the inverter becomes a single-phase AC intermediate frequency voltage and current (single-phase AC intermediate frequency voltage, current is safe), and the single-phase AC intermediate frequency voltage and current are used. The input heater generates an induction current to inductively heat an object in the boiler. The temperature of the furnace can reach up to 1400 ¡ãC, and the intermediate frequency hydrogenation can be activated by high temperature and high vacuum, the hydrogenation effect is remarkable, the cycle is short, and the production volume is large.


    The process of hydrogenation of a 1 ton fixed-point medium frequency melting furnace is as follows:

    (1) Hydrogenation is to charge the material into the mash and then into the hydrogenation furnace; start the mechanical pump and the diffusion pump, vacuum the vacuum to a vacuum of no more than 0.133 Pa, and after 30 minutes, check for leaks and leak detection. The air leakage rate is not more than 0.266 Pa/min; the power supply is heated to 700~800 ¡ãC, and the temperature is kept for 1-2 hours; the hydrogen is supplied to the furnace, the hydrogen pressure is maintained at 78-98 Kpa; the diffusion pump is stopped, and the mechanical pump is stopped after 30 minutes. , power off cooling for more than 12 hours.

    (2) Hydrogenation, the operation from charging to power feeding is similar to that of electric resistance furnace hydrogenation. The power is raised to 1200 ¡ã C, the temperature is kept for 1 hour, the temperature is lowered to 800-540 ¡ã C, and hydrogen is supplied to the furnace; the power is cooled, the diffusion pump and the mechanical pump are stopped.

    Medium frequency induction heating furnace series melting furnace features:

    (1) High melting efficiency, good power saving effect, compact structure and strong overload capability

    (2) The temperature around the furnace is low, the smoke is small, and the working environment is good.


    (3) The operation process is simple and the smelting operation is reliable.

    (4) The metal composition is uniform.

    (5) The melting temperature is fast, the furnace temperature is easy to control, and the production efficiency is high.

    (6) The furnace has high utilization rate and convenient replacement.

    (7) Long arc yoke shields magnetic flux leakage and reduces external magnetic reluctance, magnetic leakage at both ends of the shield coil, and the yoke cross section is curved. The inner side of the arc is closely attached to the outer wall to increase the effective magnetic permeability area and make the lower ring Get better support. The unique forward and reverse coils greatly increase the efficiency of the system.
