● The structure of the furnace body is composed of a furnace fixing frame and a furnace body, and the furnace fixing frame and the furnace body adopt an integral skeleton structure; 
●The tilting of the furnace body is controlled by the hydraulic system, which is realized by lifting two hydraulic cylinders on both sides of the furnace body. The resetting of the furnace body is realized by the pressure generated by the self-weight of the furnace body; 
● The height and diameter of the molten iron in the furnace are relatively high. The furnace is determined on the basis of computer analysis, the aspect ratio is increased, the natural power factor is improved, and the electrical efficiency is improved.

1 , the composition of the steel shell intermediate frequency furnace

In the cylinder mode of turndown steel commonly known induction melting furnace IF steel furnace. The steel shell intermediate frequency furnace mainly includes: closed furnace frame, inductor coil, yoke, furnace cover, dust removal system, tilting oil cylinder, furnace rotating oil cylinder, high pressure carbonless rubber hose, furnace mouth and furnace bottom casting fixed material, full set of stainless steel Water distributor, return water collector, clamp, stainless steel water inlet and outlet, etc.

3 , steel shell intermediate frequency furnace body structure selection method ?

1 ) , steel shell medium frequency furnace closed channel steel frame structure, easy to daily maintenance, overhaul; channel steel welding has become the basic structure of the hob, the overall structure is simple and sturdy, the large furnace body inclination angle of 95 degrees.

2), the platform surface knot frequency furnace refractory steel, to more fully protect the furnace, the furnace platform is not deformed.

3), intermediate frequency furnace steel welded steel construction, with appropriate support and clamping member to fix the yoke and coil induction furnace; upper member removably induction furnace, so that more convenient to replace the coil.

4), both sides of Overload steel strut intermediate frequency furnace steel member, the furnace becomes a solid support, a hydraulic tilting axis and the axis of the relocation, the shift. Ensure that the trajectory of the tapping nozzle is small, reduce the energy loss of the tapping water, and facilitate the automatic and direct connection of the molten steel to the molten steel.

5), IF steel furnace induction coil made of solid and durable Laid-free copper guide tube assembly. The water-cooled coil and the effective coil are integrally wound by a copper tube. The non-segmented induction coil is strictly insulated between two adjacent copper tubes and adopts advanced segmentation technology. An insulating sheet is implanted between adjacent induction coils, and the coil is insulated. After the paint is sprayed, it becomes a complete structure and is pressed by the upper and lower steel structures in the furnace body, and the overall structure is firm and has no deformation problem. The steel shell medium frequency furnace coil has a proper number of turns, and can obtain large electric efficiency. The copper tube of the induction coil is made of medium-aluminum copper, which has an purity of 0.99 and a conductivity of more than 100. The coil is cooled by a plurality of water channels. Water, evenly distributed. The outside of the coil is tightly wound with an insulating material. The arc-shaped insulating spacers at the same time ensure uniform coil spacing and facilitate moisture discharge.

6 ) , steel shell medium frequency furnace induction ring insulation paint using imported enamel paint, after 5 times of spraying and baking, the insulation grade can reach H grade.

7), intermediate frequency furnace steel yokes evenly force the bolt to the merger, and the coil providing a large holding force, ensure a long working life of the lining. The yoke is made of cold-rolled oriented silicon steel sheet with a thickness of 0.35mm . The tolerance of the shearing edge of the silicon steel sheet after processing is <±0.1mm . The bending of the steel shell intermediate frequency furnace is assembled. The parallelism ensures the coil and the yoke arc. Contact, fit. At the same time, multiple sets of yoke fastening devices are firm and reliable, easy to assemble, disassemble, adjust and repair, and evenly distributed along the circumference ( error ≤ 0.5) ; the yoke and the gasket between the coils are multi-layer high-quality insulating materials, including multiple layers. Mica board, multi-layer ceramic fiber board.

8 ) , in the steel shell intermediate frequency furnace top and bottom of the furnace is equipped with a molded insulation board and short circuit ring.

9), IF furnace steel furnace leakage safe and reliable protection system, when the molten steel is about to penetrate or invade permeable refractory material and a coil automatically cut off power and alarm. The leak protection system is an important part of the entire furnace protection system.

4 , steel shell intermediate frequency furnace advantages

1)     Rugged and elegant, especially for large-capacity furnaces, it requires a strong rigid structure. From the safety point of the tilting furnace, try to use steel shell intermediate frequency furnace .

2)     The yoke made of silicon steel sheet shields and emits magnetic lines of force generated by the induction coil, reduces magnetic leakage, improves thermal efficiency, increases production, and saves energy by about 5%-8% .

3)     The presence of the furnace cover reduces heat loss and increases the safety of the equipment.

4)     Long service life, steel shell medium frequency furnace due to less magnetic leakage, equipment life is much higher than aluminum shell furnace. The normal service life is generally more than 10 years.

5)   IF steel furnace safety performance much better than the aluminum furnace, aluminum melting furnace in the time due to high temperature, weight, aluminum is easily deformed, poor security. The steel shell intermediate frequency furnace uses a hydraulic tilting furnace, which is safe and reliable.
