The furnace shell of the induction melting furnace with high strength and good rigidity.
The new coreless induction melting furnace shell, with high strength and good rigidity, can effectively prevent stress and deformation of the furnace lining, and strengthen the electric furnace structure; and the overall installation is simple, and it is convenient for the maintenance of the induction coil and yoke inside the shell. It is characterized in that the furnace shell is a group of H-shaped steels whose lower ends are fixed on the periphery of the furnace bottom steel frame and are perpendicular to the furnace bottom steel frame, and there is a gap between two adjacent H-shaped steels, and the gap remains the same. The bottom steel frame of the furnace can be round like that of the existing cylindrical coreless induction melting furnace, or other shapes. The upper end of the H-shaped steel can be fixed on the periphery of the same furnace mouth ribbed ring to maintain the overall stability. Of course, the shape of the periphery of the furnace mouth stiffened ring should be the same as the shape of the periphery of the furnace bottom steel frame.
The specific quantity of H-shaped steel should be determined according to the actual size of the steel frame of the circular furnace bottom to ensure that it can be evenly distributed on the periphery of the steel frame, so that the entire furnace shell bears evenly. Welding is preferred for the connection between the H-shaped steel and the bottom steel frame and the furnace mouth reinforcement ring.
As the furnace shell, H-shaped steel mainly takes into account the excellent mechanical properties of the H-shaped steel itself, such as its wide width, large lateral rigidity, and strong bending resistance. It can effectively prevent stress and deformation of the furnace lining and reinforce the overall structure of the induction furnace; Compared with the cylindrical steel plate furnace shell, due to the simple structure and light weight of the H-shaped steel, the overall installation process of the furnace shell is easier. Finally, maintain a fixed interval between the H-shaped steel to facilitate the maintenance of the induction coil and the yoke inside the furnace shell.

Specific implementation of the furnace shell of the induction melting furnace with high strength and good rigidity
The specific implementation of the utility model will be further described in conjunction with the drawings. The specific embodiment shown in Figure 1,
The lower ends of the 16 H-shaped steels 1 are all welded to the circumference of the circular furnace bottom steel frame 2, and there is a space between two adjacent H-shaped steels.
The same interval. The upper end of the H-shaped steel is welded on the circumference of the same circular furnace mouth ribbed ring 3 to stabilize the overall structure.
Like the existing induction melting furnace, induction coils and yokes are arranged in the furnace shell, and the spacing between the H-shaped steels facilitates their maintenance. At the same time, the superior mechanical properties of the H-beam itself bring better load-bearing capacity and rigidity to the furnace shell.
Effectively strengthen the overall structure of the induction melting furnace.
