Abstract

A medium frequency furnace magnetic yoke is mounted in a medium frequency furnace and composed of a plurality of stacked silicon steel sheets, two side plates for clamping the silicon steel sheets, and a connection plate welded between the two side plates, wherein the magnetic yoke also comprises a screw rod, insulation mats and nuts connected on the two ends of the screw rod, through holes for the screw rod passing through are formed on the side plates and the silicon steel sheets, and an insulation sleeve is arranged between the silicon steel sheet and the screw rod. The connection in the medium frequency furnace magnetic yoke is reliable, and the silicon steel sheets are effectively prevented from expanding from the welding positions of the connection plate and the side plates.

Description

The intermediate frequency furnace yoke
Technical field:
The utility model relates to a kind of intermediate frequency furnace, specifically is the yoke in a kind of intermediate frequency furnace.
Background technology:
We know; Intermediate frequency furnace is a kind of apparatus for melting metal; Through feeding the intermediate frequency alternating current to its induced inside coil; Make induction coil produce highdensity magnetic line of force cutting and be contained in the metal derby in the molten bath, induction coil center, utilize electromagnetic induction principle to make the powerful eddy current of the inner generation of metal derby, heat and melt metal derby with this.The magnetic line of force in order to ensure induction coil produced can effectively gather in the molten bath; The induction coil periphery of existing intermediate frequency furnace also is evenly equipped with a plurality of yokes; Conventional yoke generally comprises multi-disc silicon steel sheet stacked together and two blocks of side plates that are used to clamp the multi-disc silicon steel sheet, is welded with connecting plate between two blocks of side plates.In the process of intermediate frequency furnace smelting metal piece; Yoke all will be born from the baking of high temperature more than 1600 degrees centigrade in the molten bath usually; After receiving and toasting, silicon steel sheet stacked together is prone to send out rise, overlong time, and the multi-disc silicon steel sheet has from the risk of connecting plate and side plate weld spreading.
The utility model content:
The technical problem that the utility model will solve is, provides a kind of connection reliable, can effectively avoid the intermediate frequency furnace yoke of multi-disc silicon steel sheet from connecting plate and side plate weld spreading.
The technical solution of the utility model is; A kind of intermediate frequency furnace yoke with following structure is provided: comprise silicon steel sheet and two blocks of side plates that are used to clamp the multi-disc silicon steel sheet that multi-disc is stacked together; Be welded with connecting plate between two blocks of side plates, wherein, the insulation cushion and the nut that also comprise screw rod and be connected the screw rod two ends; All have the through hole that supplies screw rod to penetrate on side plate and the silicon steel sheet, be provided with insulating case between silicon steel sheet and the screw rod.
After adopting above structure; Compared with prior art; The utility model intermediate frequency furnace yoke has the following advantages: the utility model intermediate frequency furnace yoke is except being welded with the connecting plate between two blocks of side plates as prior art; Also between side plate and multi-disc silicon steel sheet, be installed with screw rod; After treating the two ends fastening nut of screw rod, side plate and multi-disc silicon steel sheet will connect together under the effect of nut clamping force tightly, thereby have effectively avoided the multi-disc silicon steel sheet because of being heated for a long time from the risk of connecting plate and side plate weld spreading.
Description of drawings:
Fig. 1 is the main TV structure sketch map of the utility model intermediate frequency furnace yoke;
Fig. 2 is the section structure for amplifying sketch map of edge " A-A " line among Fig. 1.
Embodiment:
Below in conjunction with accompanying drawing and embodiment the utility model intermediate frequency furnace yoke is done further explain:
As depicted in figs. 1 and 2; In this embodiment, the utility model intermediate frequency furnace yoke comprises screw rod 2, be connected insulation cushion 1 and nut 3, the multi-disc at screw rod 2 two ends silicon steel sheet 4 stacked together and two is used to clamp all be welded with on the lateral wall of 7, two blocks of side plates 7 of side plate of multi-disc silicon steel sheet 4 and is used for cooling water box 6 that silicon steel sheet 4 is cooled off; Be welded with ten connecting plates 5 between two blocks of side plates 7; Each five blocks of front and back all have the through hole 9 that supplies screw rod 2 to penetrate on side plate 7 and the silicon steel sheet 4, be provided with insulating case 8 between silicon steel sheet 4 and the screw rod 2; Insulating case 8 is enclosed within on the screw rod 2, is provided with plain washer 10 between nut 3 and the insulation cushion 1.
Above-described embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that those of ordinary skills make the technical scheme of the utility model all should fall in the definite protection range of the utility model claims.
