Induction melting furnace overall design standard

     The induction melting furnace is mainly composed of a furnace body, a tilting furnace transmission device, an operation console, a bus bar, a capacitor cabinet (or combined with an intermediate frequency power supply device), an intermediate frequency power supply device, and a cooling water circuit system. Generally, an intermediate frequency power supply unit is equipped with one or two induction melting furnaces (one for melting, the other for standby or simultaneous heat preservation, pouring and charging operations, and also for more furnaces, such as two simultaneous melting The other is used for heat preservation, pouring and charging to increase productivity. If multiple furnaces are equipped, it is necessary to equip the furnace with the corresponding capacity.

The furnace body is generally a vertical tilting structure, the furnace is made of refractory concrete or other types of concrete, the furnace cover of the upper part of the furnace body can be opened and closed, and the tilting part of the furnace body is mounted on the fixed hob, hydraulic or electric Or manually tilting, induction melting furnaces are usually floor-mounted or semi-underground.

    The design of induction melting furnace should focus on the rigidity of the overall assembly of the furnace body, the influence of magnetic flux leakage on the structural material, the electrical performance of the induction coil, the alarm of the leaking furnace, and the monitoring of the waterway. The safety measures should be effective and reliable. The output power of the intermediate frequency power supply should be adjusted according to the needs of various working conditions such as oven, melting and heat preservation; when multiple furnaces are operated at the same time, the power distribution of each furnace should be adjusted according to the process requirements. Under the premise of ensuring safety, operation and maintenance, the induction melting circuit bus and bus cables should be as short as possible to reduce line impedance and loss.
