        Structural requirements for heavy induction melting furnace
    With the continuous improvement of the power density of the new heavy-duty induction melting furnace, the requirements for the safe operation of the furnace, the improvement of the life of the furnace lining and the reduction of noise have become higher and higher, and the rationality of the furnace structure has become more and more important. Among them, the heavy-duty steel shell furnace has many advantages such as strong durability, high efficiency, high productivity, low noise, and easy maintenance.
       The induction melting furnace is different from the frame furnace. It is a high-strength ring-shaped steel shell with multiple larger inspection openings. When the furnace is running, the inspection openings are closed, and each inspection opening can be opened during maintenance. The heavy-duty steel shell furnace has a strong internal structure, which can avoid possible deformation caused by tilted iron casting and prolong the life of the furnace lining. Moreover, due to the enclosed solid furnace shell and the addition of sound-absorbing and insulating materials inside, the working noise is greatly reduced. The strong steel shell can also effectively protect the induction coil from the danger of splashing metal, so that the furnace has the greatest safety during operation. In order to effectively heat insulation and improve the life of the furnace lining, the heavy steel shell furnace is also equipped with cooling rings on the top and bottom respectively, which has a uniform lining temperature and reduces thermal expansion. The stainless steel cooling ring with low energy consumption and high strength greatly improves the efficiency of the furnace.
      The new heavy-duty induction melting furnace not only has a strong steel shell, but also designed a thick-walled tube structure coil specially used for melting in the induction melting furnace. By correctly selecting the distance between the turns of the induction coil, the coil has the highest conversion efficiency and the smallest resistance. The thick-walled induction coil has large current-carrying cross-section, uniform wall thickness, and is not prone to damage caused by arc and expansion. The coil adopts a special support system, and each turn is firmly locked, with good rigidity, which reduces the electromagnetic force. Vibration greatly prolongs the service life of the furnace lining. In addition, 50% of the magnetic yoke is covered around the induction coil, which effectively changes the distribution of the magnetic field. At the same time, the isolation cushion also reduces noise and vibration and increases the efficiency of the yoke. The heavy-duty steel shell furnace also adopts an extended coil design that extends the induction coil beyond the furnace substrate, so that the coupling between the charge load and the magnetic field from the top to the bottom of the furnace body is very uniform, which improves the energy conversion efficiency and reduces the stirring caused by the magnetic field. The influence of force on the bottom lining.
      Reasonable furnace structure is very important. Heavy steel shell furnace is only one of them. Many manufacturers are working hard to improve the furnace structure to adapt to the application and development of induction melting furnaces.
