What is steel shell melting furnace?

   The new steel shell melting furnace adopts steel frame structure, which is composed of a furnace fixed frame and furnace body, and the furnace fixed frame and furnace body adopt an integral skeleton structure. The tilting position of the furnace body is controlled by a hydraulic system, which is realized by two hydraulic cylinders on both sides of the furnace body. Coil height, diameter ratio is appropriate, high power factor, high electrical efficiency.

What is the steel shell melting furnace working principle?

 The intermediate frequency steel shell melting furnace adopts the basic principle of induction heating, “induction heating” is the method of electromagnetic induction to generate induction current in the load itself to heat the load. The law of electromagnetic induction e=W* -D φ /dt is also used.

What is the structure of steel shell melting furnace?

  ZHENGZHOU KETCHAN medium frequency steel shell melting furnace is composed of a medium frequency power supply cabinet, compensation capacitor bank, steel shell furnace body, magnetic yoke and water cooling cable, hydraulic station, tilting furnace control box, and so on.

  • The inter-turn clearance of the induction coil is convenient for maintenance and conducive to water vapor release;
  • To improve the working environment, smoke collecting device can be selected.

How is the steel shell melting furnace working efficiency and loss?

  • Heat loss caused by current flow in induction coil: the loss is taken away by cooling water. This part of the loss is the main loss of the system, which is related to inductor structure, physical properties of charge, and heating frequency. The “electric efficiency” is commonly used to describe this loss. Electrical efficiency is the ratio of the energy transmitted to the heated workpiece to the energy the sensor receives from the power source.
  • Heat loss of steel shell melting furnace: the loss caused by heat dissipation of the heated workpiece, which is second only to inductor loss. This loss is often described by the term “thermal efficiency”, which is the ratio of the net heat applied to the workpiece to the total heat received from the induction coil.
  • The transmission loss of steel shell melting furnace: the loss caused by cable and bus from frequency conversion power supply to load, generally in 2% ~ 7%.
