〈産業上の利用分野〉
本発明は制振鋼板製造装置に係り、特に、制振鋼板の製
造過程における加熱装置に関する。DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a damping steel sheet manufacturing apparatus, and particularly to a heating device used in the manufacturing process of vibration damping steel sheets.
〈従来の技術〉
制振鋼板を製造する過程においては、２枚の鋼板の間に
高分子材料を挿入したのち、鋼板を加熱して高分子材料
を溶かし、鋼板どうしを高分子材料で接着する必要があ
る。特に、性能の良い制振鋼板を作製するには鋼板全体
を一様に加熱する必要がある。<Conventional technology> In the process of manufacturing damping steel plates, a polymeric material is inserted between two steel plates, the steel plates are heated to melt the polymeric material, and the steel plates are bonded together using the polymeric material. There is a need. In particular, in order to produce a damping steel plate with good performance, it is necessary to uniformly heat the entire steel plate.
第５図に、制振鋼板製造装置の従来例を示す。FIG. 5 shows a conventional example of a damping steel plate manufacturing apparatus.
同図において、２つの鋼板用ペイオフリールＩＡ、ＩＢ
にそれぞれ巻かれた鋼板２Ａ。In the same figure, two steel plate payoff reels IA and IB
Steel plate 2A each wound on.
２Ｂの間に高分子材料用ペイオフリール３に巻かれた板
状の高分子材料４を、ラミネート四−ル５によって挾み
込む。その後、ヒータ炉６によって鋼板２Ａ、２Ｂ及び
高分子材料４の全体を加熱して高分子材料を溶かし、圧
着ロール７により鋼板２Ａ、２Ｂを接着した後、冷却炉
８、乾燥炉９を経て制振鋼板２０とし、巻き取りロール
１０に巻き取る。A plate-shaped polymer material 4 wound around a payoff reel 3 for polymer material is sandwiched between the laminate wheels 5 and 2B. Thereafter, the entire steel plates 2A, 2B and polymer material 4 are heated in a heater furnace 6 to melt the polymer material, and the steel plates 2A, 2B are bonded together by a pressure roll 7, and then passed through a cooling furnace 8 and a drying furnace 9. A shaken steel plate 20 is used and wound up on a winding roll 10.
従来、ヒータ炉６での加熱は、ガスバーナ、ラジアント
チューブにより行っており、第６図に加熱特性の例を示
す。Conventionally, heating in the heater furnace 6 has been performed using a gas burner or a radiant tube, and an example of the heating characteristics is shown in FIG.
〈発明が解決しようとする課題〉
従来技術では、第６図から判るように、鋼板の温度は板
幅方向に関して一様ではな（、板中央部と板端部で大き
く異なっている。この理由は、従来のヒータ炉６がガス
バーナやラジアントチューブによる間接的な加熱である
ため、雰囲気の影響を受は易く、鋼板全体を均一に加熱
することが困難であったからである。<Problems to be Solved by the Invention> In the prior art, as can be seen from FIG. This is because the conventional heater furnace 6 uses indirect heating using a gas burner or a radiant tube, so it is easily affected by the atmosphere and it is difficult to uniformly heat the entire steel plate.
また、ガスバーナやラジアントチューブによる加熱では
、一定温度ｆｌｌｌＪ＃を行う際の時定数が大きく応答
性が悪いという欠点がある。Further, heating using a gas burner or a radiant tube has a disadvantage that the time constant when performing constant temperature flllJ# is large and the response is poor.
これに伴い、設定温度までの立ち上げに時間を長く要す
るため、ヒータ炉６が大型化するという欠点がある。Accordingly, since it takes a long time to raise the temperature to the set temperature, there is a drawback that the heater furnace 6 becomes larger.
この理由は次の通りである。The reason for this is as follows.
ここで、Ｐ：昇温電力（Ｗ）
Ａ：被加熱物表面積（ｍ′）
ａ：熱伝達率（Ｋｃ ａ ｌ ／ ｒｎ’ ｈ ℃）Ｔ
ｏ：外気温度（℃）
ＣＰ：被加熱物比熱（Ｋｃａｌ／ ｋｇ ’Ｃ）Ｍ：被
加熱物重量（ｋｇ）
式（１）は−次遅れの式であり、時定数τばτ＝ＣＰＭ
／Ａα ・・・式（２）となり、被加熱物
の重量Ｍが大きいほど、時定数が大きくなる。普通、ガ
スバーナやラジアントチューブを用いたヒータ炉６では
、均熱化を図るため囲い部分も加熱するから被加熱物は
鋼板２Ａ、２Ｂだけではなく、その分Ｍが大きくなる。Here, P: heating power (W) A: surface area of the heated object (m') a: heat transfer coefficient (Kc a l / rn' h °C) T
o: Outside temperature (°C) CP: Specific heat of the object to be heated (Kcal/kg 'C) M: Weight of the object to be heated (kg) Equation (1) is a -order lag equation, and the time constant τ is τ = CPM
/Aα...Equation (2) is obtained, and the larger the weight M of the object to be heated, the larger the time constant becomes. Normally, in a heater furnace 6 using a gas burner or a radiant tube, the surrounding area is also heated in order to equalize the temperature, so the objects to be heated are not only the steel plates 2A and 2B, and M becomes larger accordingly.
従って、時定数τが大きくなり、立ち上げに時間を要し
ヒータ炉６が大型化して加熱時間が長びくと共に、一定
温度制御の際の加熱温度変化に対する応答性も悪くなる
。Therefore, the time constant τ increases, it takes time to start up, the heater furnace 6 becomes larger, the heating time becomes longer, and the responsiveness to heating temperature changes during constant temperature control also deteriorates.
本発明は上述した従来技術に鑑み、制振鋼板を製造する
過程で鋼板全体を均一に加熱でき、且つ時定数が小さい
加熱装置を備えた制振鋼板製造装置を提供することを目
的とする。In view of the above-mentioned prior art, it is an object of the present invention to provide a vibration damping steel plate manufacturing apparatus that is capable of uniformly heating the entire steel plate during the process of manufacturing the vibration damping steel plate and is equipped with a heating device with a small time constant.

入した鋼板等の導体板を加熱する装置として誘導加熱装
置を備えたことを特徴とするものである。Means for Solving the Problems> The vibration damping steel plate manufacturing apparatus according to the present invention is characterized in that it is equipped with an induction heating device as a device for heating a conductive plate such as a steel plate with a polymer material inserted therebetween. be.
く作 用〉
誘導加熱装置を用いると交番磁界が導体板例えば鋼板に
加わり、交番磁界の変化を妨げるように導体板の内部に
うず電流が発生し、うず電流のジュール発熱によって導
体板が加熱される。When an induction heating device is used, an alternating magnetic field is applied to a conductor plate, such as a steel plate, and eddy currents are generated inside the conductor plate to prevent changes in the alternating magnetic field, and the conductor plate is heated by the Joule heat generated by the eddy current. Ru.
従って、鋼板等の導体は直接加熱されることになるので
、雰囲気の影響を受は難（なり、板全体が均一に加熱さ
れる。Therefore, since a conductor such as a steel plate is directly heated, it is hardly affected by the atmosphere, and the entire plate is heated uniformly.
また、直接加熱であるから、削成（ｚ）、 ｆ２）にお
ける重量Ｍが導体板のみのものとなり、従来よりも時定
数が極めて小さくなる。従って、加熱の応答性が良＜、
温度管理が短時間ですみ、加熱装置が小形化できる。Furthermore, since direct heating is used, the weight M in the cutting (z), f2) is only for the conductor plate, and the time constant is much smaller than in the conventional case. Therefore, the heating response is good.
Temperature control can be done in a short time, and the heating device can be made smaller.
