By described iron core part 13, form magnetic flux that periphery coil 14 produces sidewall and the sidewall of the second hydraulic container 82 magnetic circuit that passes through the both ends, the left and right sides of metal plate and belt B by the first hydraulic container 81.Thus, the both ends, the left and right sides of heating of metal strip B reliably.
In addition, for the heating that suppresses the first hydraulic container 81 and the second hydraulic container 82 and increase the Ratio of fever at the both ends, the left and right sides of metal plate and belt B, the slit S that processes appropriate depth at the iron core part contact-making surface of the first hydraulic container 81 and the second hydraulic container 82 reduces short circuit current.
In addition, identical with described the second execution mode, by adjusting planar coil 3,4 energising amount and the energising amount of periphery coil 14, can control the Temperature Distribution of the Width of metal plate and belt B.
In addition, the utility model is not limited to described each execution mode.
For example, in described the second execution mode, take the induction heating equipment of hydraulic pressurization mode as prerequisite, possess periphery coil 9,10 and cover 11,12, but also can be in described the first execution mode, possess periphery coil 9,10 and cover 11,12.In this case, because induction heating equipment 100 does not comprise hydraulic container 81,82, so periphery coil 9,10 be arranged on the first periphery magnetic circuit component 5 and the second periphery magnetic circuit component 6 around, and the first cover 11 and the second cover 12 are arranged on the first periphery magnetic circuit component 5 and the second periphery magnetic circuit component 6.
In addition, in described the 3rd execution mode, take the induction heating equipment of hydraulic pressurization mode as prerequisite, possess iron core part 13 and periphery coil 14, but in described the first execution mode, also can have iron core part 13 and periphery coil 14.In this case, because induction heating equipment 100 do not comprise hydraulic container 81,82, therefore the mode with the side that contacts respectively the first periphery magnetic circuit component 5 and the second periphery magnetic circuit component 6 arranges iron core part 13.
In addition, as shown in figure 11, the first planar coil 3 and the second planar coil 4 can be divided into a plurality of tabular separate windings, can with about the mode that staggers dispose described a plurality of tabular separate winding.Figure 11 represents planar coil 3,4 is divided into the situation of mutual structure identical and two tabular separate winding C1, C2 that shape is identical.With planar coil 3,4 identical, described two tabular separate winding C1, C2 overlook in the form of a substantially rectangular, and its central part is provided with the center that forms the hub of a spool magnetic circuit C11, C12 unshakable in one's determination.The central shaft of two tabular separate winding C1, C2 disposes towards equidirectional, and the central shaft of a side tabular separate winding C1, is configured in the coiling diameter position in two with the winding around of the opposing party's tabular separate winding C2.Namely, be that the coiling diameter of the winding around of 2S, tabular separate winding C1, C2 is in the situation of D at the width dimensions of the center of establishing tabular separate winding C1, C2 unshakable in one's determination C11, C12, the mode that becomes D/2+S with the amplitude that staggers of two central shafts is configured.Thus, can make the Temperature Distribution about metallic plate more even.
In addition, as shown in figure 12, also can adopt following manner: the first planar coil 3 and the second planar coil 4 are divided into a plurality of tabular separate winding C, at Width configuration at least one tabular separate winding C vertical with throughput direction, consist of thus coil unit Cx, dispose a plurality of coil unit Cx along throughput direction, and be configured at least one coil unit Cx, the outside of tabular separate winding C from conductivity sheet material W such as metallic plates to Width that consists of this coil unit Cx is outstanding.Specifically, the tabular separate winding C that consists of two adjacent coil unit Cx is in the Width configuration of staggering.
In Figure 12, the first planar coil 3 and the second planar coil 4 are divided into four tabular separate winding C1～C4 that are identical shaped, consist of coil unit Cx1 at Width configuration two tabular separate winding C1, the C2 vertical with throughput direction, consist of coil unit Cx2 at Width configuration two tabular separate winding C3, the C4 vertical with throughput direction, along throughput direction coil unit Cx1, Cx2 are configured to two sections.In addition, be configured to: the right side part of the tabular separate winding C1 on the right side of the coil unit Cx1 of formation conveying upstream is outstanding to the right from the right-hand end of conductivity sheet material W.In addition, be configured to: the left part of the tabular separate winding C4 in the left side of the coil unit Cx2 in formation conveying downstream is outstanding to the left from the left end of conductivity sheet material W.
At this, the coiling diameter that width dimensions at the center iron core of establishing tabular separate winding C1～C4 is 2S, establish the winding around of tabular separate winding C1, C2 is in the situation of D, and tabular separate winding C1～C4 becomes at most for the caloric value of " D/2+S " position apart from the center.
Therefore, carrying midway, at least one coil unit Cx, an end of the Width of conductivity sheet material W or another end are by " D/2+S " position of the tabular separate winding C of this coil unit of formation Cx.Thus, the efficiently Width of electric conduction of heating sheet material W end or another end.In Figure 12, the right-hand end of conductivity sheet material W is by " D/2+S " position of tabular separate winding C1, and the left end of conductivity sheet material W is by " D/2+S " position of tabular separate winding C4.In other words, be configured to: carrying the coil unit Cx1 of upstream and carrying the amplitude that staggers of the coil unit Cx2 in downstream is D/2+S.

By disposing in this wise tabular separate winding C1～C4, can with the central portion of the conductivity sheet material W both ends of the Width of electric conduction of heating sheet material W similarly, thereby can make uniformity of temperature profile on the Width of electrically conductive plate material W.
In addition, except shown in Figure 12, also coil unit Cx can be configured to more than three sections along throughput direction, also can consist of each coil unit Cx by a tabular separate winding C or the tabular separate winding C more than three.At this moment, the amount of staggering of the tabular separate winding C by adjusting adjacent coil unit Cx can make the uniformity of temperature profile of electrically conductive plate material W on Width.In Figure 13, expression will be configured to three sections situation by the coil unit Cx that three tabular separate winding C consist of.Be configured in Figure 13: the coil unit Cx1 that carries upstream is D/2+S with the amplitude that staggers of the coil unit Cx3 that carries downstream, and carries the coil unit Cx2 in the middle reaches amplitude that staggers (D/4+S/2) in the middle of becoming.
In addition, be made of in the situation of each coil unit Cx plural tabular separate winding C, the electric current that flows through each tabular separate winding C by control is regulated magnetic flux, can control the Temperature Distribution of conductivity sheet material W on Width.
In addition, the tabular separate winding C that consists of coil unit Cx need not to be of similar shape, in order to make the uniformity of temperature profile on the Width, and can the different tabular separate winding of assembled dimension.
