、鋼板２．２を電極として高周波誘電加熱が施される。The composite laminated steel plate 1, in which the resin 3 is sandwiched between the steel plates 2.2 via the pinch rolls 6.6, enters a high frequency dielectric heating furnace 8 and is subjected to high frequency dielectric heating using the steel plates 2.2 as an electrode.

パーカラーが発生しない。なお、高周波誘電加熱の原理
および高周波誘電加熱炉８の構造については後述する。At this time, only the resin 3 is melted and the temperature on the surface of the steel plate 2.2 hardly rises, so that no temper color occurs on the surface of the steel plate 2.2. The principle of high frequency dielectric heating and the structure of the high frequency dielectric heating furnace 8 will be described later.

It is crimped with F force. After that, correction iE (

Insert between electrodes 1 and 2, and connect high frequency power source 1 to this.
1, a high frequency voltage V is applied. Many of the molecules that make up a dielectric material form electrical dipoles 10 with equal positive and negative charges at both ends, and a dielectric material can be thought of as an aggregate of many such dipoles 10-. Either the individual dipoles lO are oriented in arbitrary directions, or when a voltage is applied to the electrodes, the positive and negative charges of the dipoles create an attractive force with the electrode potentials of the opposite sign, causing their orientation to change. As a result of the rotation, the valley dipole′
flO will align in the direction of the electric force. However, since the polarity of the voltage changes periodically at high frequency 1', when the voltage polarity of the electrode is reversed, the direction of the bipolar %10 is also reversed accordingly. In this way each molecule of the dielectric is
When they repeat reversals according to the frequency of 1, they collide and rub against each other, generating heat. The following is the heat generation principle of high frequency dielectric heating, and it is easy to see that the higher the frequency, the greater the amount of heat generated per unit.

生することはない。In this way, high-frequency dielectric heating differs from external heating in which the inner body of the steel plate 2.2 is also heated; the internal resin 3 itself generates heat; By selecting 1, the resin 3 can be uniformly and rapidly heated and melted. Therefore, even if the temperature of the steel plate rises at the interface between the steel plate 2.2 and the resin 3, the heat will not be transmitted to the surface of the steel plate 2.2, and therefore, temper color will not occur on the surface of the steel plate 2.2. do not have.
次に高周波誘電加熱炉８の構造について説明する。その
構造を第２図に示す。Next, the structure of the high frequency dielectric heating furnace 8 will be explained. Its structure is shown in FIG.

よう構成することが好ましい。In order to apply high-frequency dielectric heating to the composite laminated steel plate 1 based on the principle as described in L, it is necessary to apply a high-frequency voltage using the steel plate 2.2 as an electrode. However, in the present invention, the composite laminated steel plate 1 is 2, at least a pair of dielectric heating electrode rolls 9, 9 are arranged so as to contact and roll on the surfaces of the steel plates 2, 2, and high frequency waves are applied to these electrode rolls 9°9. It is preferable to configure the power source 11 to apply a high frequency voltage.

ことなく樹脂３を溶融するようにする。In the high frequency dielectric heating furnace 8 having such a structure, the properties of the steel plate 2.2 and the resin 3 constituting the composite laminated steel plate 1,
Considering the dimensions, line running speed, etc., select the number of electrode rolls 9 and the frequency and voltage of the high-frequency electric current [11] to achieve appropriate melting of the resin 3, that is, the surface temperature of the steel plate 2.2. The resin 3 should be melted without any melting.

な樹脂３の構成を以ドに説明する。- Generally speaking, rapidly heating the object to be heated (resin 3), that is, increasing the calorific value of the resin 3, makes it more difficult for heat to be transferred to the surface of the steel plate and is more effective in preventing the occurrence of temper color. To achieve this, it is conceivable to increase the frequency and/or voltage of the power source 11, but in the present invention, by improving the structural properties of the resin 3 constituting the composite laminated steel plate l, the melting of the resin 3 is more effectively achieved. can be done. The structure of such resin 3 will be explained below.

The constituent materials of the single layer resin 3 sandwiched between the layers include thermal 1iJfi resins such as polyolefins such as polypropylene, polyamides such as nylon, polyesters such as polyethylene terephthalate, or copolymers and modified products thereof. etc. can be mentioned.

、より急速な樹脂の溶融が可能となる。(2) Next, as shown in FIG. 3, the resin 3 may be the resin (2) above, preferably containing a filler 12 having a dielectric constant ε of 3 or more, such as carbon black or magnetite. Thermoplastic resin alone has a relatively low dielectric constant ε, so when high-frequency dielectric heating is applied, the amount of heat generated by the resin is small, or the inclusion of the filler 12 accelerates heat generation and melts the resin more rapidly. It becomes possible.
なお、フィラーの誘電率εを３以北とするのは、使用す
る樹脂よりも高い誘電率か必要だからである。The dielectric constant ε of the filler is set to 3 or higher because it is necessary to have a dielectric constant higher than that of the resin used.

２．２と接触する樹脂層３ａ、３ａには上記■と同様の
フィラー１２を含有させる。■ As shown in Figure 4, the resin 3 has a three-layer structure (3a/
3b/3a), and the outer resin layer, that is, the resin layer 3a, which is in contact with the steel plate 2.2, contains the same filler 12 as in the above (2).

溶融が可能となる。The steel plate 2.2 and the resin 3 only have to be tightly adhered to each other at their interface. Therefore, by configuring the resin 3 as described above, the efficiency of the filler is increased and the resin layers 3a, 3a near the interface are preferentially melted, so that the resin can be melted more rapidly.
なお、樹脂層３ａ、３ａおよび３ｂの構成材料としては
