り離したり結合させる手段とを設ける。That is, as an induction heating alloying furnace, in an alloying furnace of a magnetic plate material using a solenoid type induction heating coil as a heating source, the induction heating coil cut by a plane parallel to the longitudinal axis of the plate material, The movable side of the contactor having the plate-like protrusions, each end of which is coupled to one side of the induction heating coil, and the other end of the induction heating coil of the cutting portion are coupled to each other and receive the protrusions. There is provided a fixed side of the contactor having a backing plate, and means for moving one side of the induction heating coil to disconnect or connect the induction heating coil.

ンスの流路となる。When operated in the opposite direction, one side of the induction heating coil moves in the opposite direction, and the protrusion of the movable portion of the contactor is inserted into the receiving plate of the fixed portion and coupled. At this time, the side surface of the plate-shaped projection comes into contact with the side surface of the receiving plate to form a current path. Since the wide surfaces are in contact with each other, the flow path has a low loss and a low impedance with respect to the high frequency current.
従って、コイルを流れる電流は、従来例とほぼ同程度に
流れ、同程度の誘導加熱作用がえられる。Therefore, the current flowing through the coil flows to about the same level as the conventional example, and the same level of induction heating action can be obtained.

アターン／メータで決る。このため、切断位置の影響は
ほとんど受けない。Due to the characteristics of the solenoid coil, the magnetic field distribution in the coil is almost uniform regardless of the shape of the loop, and its strength is determined by the ampere of the current flowing through the coil, that is, ampere turn / meter. Therefore, the cutting position is hardly affected.

The fixed side 7 and the movable side 8 are joined together by a plate-like fork-shaped protrusion on the movable side 8.
12 and the fixed side 7 has a backing plate 10 that sandwiches the protrusion 12.
A penetrating rod 13 is vertically passed through the receiving plate 10, and a holding spring 11 surrounding the penetrating rod 13 is provided outside the receiving plate 10. Furthermore, the receiving plate 10
One end of is connected to the fixed side 7 via a U-shaped multilayer copper strip 9. Further, the contactor 5 is provided with a passage 14 for water cooling.

さくしている。言葉をかえて詳しく説明すると、可動側
８のフォーク状の突起12と固定側７の２枚の受板10が接
触し、コイルに流れる電流路を形成する。When the moving device 6 is operated in the opposite direction, the movable side 8 moves in the opposite direction, and the protrusion 12 is pushed between the receiving plates 10 to be connected. The contact resistance of the joint is kept small by the holding spring. Further, the contactor 5 is made compact to reduce the inductance. In other words, the fork-shaped projection 12 on the movable side 8 and the two receiving plates 10 on the fixed side 7 contact each other to form a current path flowing through the coil.

えバネ11で接触面圧を確保することにより、低損失の接
触器となっている。At this time, in order to reduce heat generation due to contact resistance, the projection 12 and the receiving plate 10 are in a flat plate shape and contact with each other over a wide area, and the pressing spring 11 secures the contact surface pressure, so that a contactor with low loss is provided. Has become.
突起12が、押えバネ11で加圧された２枚の受板10へ挿入

In addition, since the current path is divided into two, the impedance is connected in parallel, and the impedance decreases. Further, each contactor body is water-cooled via the cooling water nozzle 14 to prevent an increase in loss due to a temperature rise.
