Abstract
The utility model relates to a magnetic yoke component in the coreless medium frequency induction furnace, pertaining to the technical field of the coreless medium frequency induction furnace, whose structure is composed of a silicon steel coil, a stainless steel plate, a stainless steel clip, a cooling copper pipe and a copper plate; wherein, the stainless steel plate and the stainless steel clip realize connection by welding, the cooling copper pipe is welded together with the copper plate and is arranged between the silicon steel coil and the stainless steel plate; the stainless steel clip combines the stainless steel plate, the copper plate and the silicon steel coil. The utility model has the advantages of complete radiation and effective silicon steel coil cooling, which moreover welds the arched stainless steel plate and two stainless steel side plates, which promises pressing force and is not apt to deform and split the silicon steel coil, making low noise. Using the current structure, the utility model not only enhances the cooling effect, improves the whole intensity and rigidity of the magnetic yoke, but also applies to occasions of comparatively large power, much heat absorption and great vibration.
Description
Technical field
The utility model relates to a kind of yoke assembly that is used for centreless intermediate frequency frequency-conversion electric induction furnace, belong to centreless frequency-conversion electric induction furnace technical field.
Background technology
Original yoke adopts both sides corrosion resistant plate outside weld copper plumbing, weld mutually with the both sides corrosion resistant plate with the curved stainless steel plate above, its major defect is that heat radiation is insufficient, can not effectively cool off silicon steel sheet, and weld mutually with two stainless steel side plates with the curved stainless steel plate, do not have clamping force, very easily make silicon steel sheet distortion, division, produce big noise.It is bigger to be not suitable for power, and the occasion more and that vibration is bigger of absorbing heat is used.
Summary of the invention
The purpose of this utility model is the defective at above-mentioned existence, proposes a kind of yoke assembly of novel structure, can replace existing yoke, is assemblied in the centreless intermediate frequency frequency-conversion electric induction furnace.Thereby can effectively overcome the defective that prior art exists, technical solution of the present utility model: its structure is made up of silicon steel sheet, corrosion resistant plate, stainless steel clip, cooling copper tube and copper coin, wherein corrosion resistant plate and stainless steel clip are by being welded to connect, cooling copper tube and copper coin weld together, and be arranged between silicon steel sheet and the corrosion resistant plate, the stainless steel clip is unified into an integral body with corrosion resistant plate, copper coin and silicon steel sheet.
Advantage of the present utility model: heat radiation is fully effectively cooled off silicon steel sheet, and is welded mutually with two stainless steel side plates with the curved stainless steel plate, and clamping force is arranged, and is difficult for making silicon steel sheet distortion, division, and noise is low.Adopt existing structure, strengthened cooling effect greatly, improved yoke integral intensity and rigidity, can be fit to the occasion that power is big, heat absorption is more and vibration is bigger and use.
Description of drawings
Accompanying drawing 1 is that the utility model has structural representation
Accompanying drawing 2 is prior art constructions schematic diagrames.
Among the figure 1 is silicon steel sheet, the 2nd, corrosion resistant plate, the 3rd, stainless steel clip, the 4th, cooling copper tube, the 5th, copper coin.
The specific embodiment
Contrast accompanying drawing 1,
Silicon steel sheet 1 absorbs the unnecessary magnetic line of force that inductor sends, and avoids the eddy-current heating of remaining part, is the main body of yoke, stainless steel clip 3 is unified into an integral body with corrosion resistant plate 2 and cooled copper 5, silicon steel sheet 1, and improving its rigidity, cooling copper tube and copper coin are the heat radiations that increases it, play cooling effect.Corrosion resistant plate 2 has the effect that compresses, and it passes to silicon steel sheet 1 with stainless steel clip 3 deformation forces, and the distortion thrust that stainless steel clip 3 is produced passes to corrosion resistant plate 2 and silicon steel sheet 1.Cooling copper tube 4 and copper coin 5 weld together and are set between silicon steel sheet 1 and the corrosion resistant plate 2, when yoke was worked, cooling copper tube 4 logical cooling waters were to reduce silicon steel sheet 1 owing to absorbing the temperature rise that the magnetic line of force produces, copper coin 5 increases radiating effect, avoids copper pipe 4 compressive deformations to influence water-flowing amount.The course of work is to connect power supply when inductor, and coil produces induced field, and the magnetic line of force in the inductor produces eddy current to the work heating, and the outer magnetic line of force of inductor will heat furnace binding, and this is extremely harmful.After placing yoke around the inductor, the outer magnetic line of force of inductor will effectively be absorbed by yoke, stop the heating to furnace binding.In addition, furnace lining material and molten iron are arranged in the induction coil, when stove was toppled over molten iron, the yoke around the coil had played support and protective effect to coil.
