Since pressure bonding is performed selectively after induction heating using , it is possible to manufacture cladding materials with desired conditions.

よって一体化したクラッド材が提供されている。C1 Conventional technology A cladding material in which different types of metal plates are integrated by pressure bonding or rolling in order to obtain a material that has properties that are difficult to obtain with metal materials alone, such as high strength and excellent corrosion resistance. is provided.

できる金属板材の幅や厚さに制限が生じる。When manufacturing this clad material by a method such as cold pressure bonding using rolls, it is difficult to manufacture the clad material because of its high hardness (if it contains metal plates with high deformation resistance, it is necessary to apply a large pressure force for bonding, A large-scale rolling mill is required, or there are restrictions on the width and thickness of the metal plates that can be joined.

な炉長を備えていた。Therefore, a conventional method has been used in which metal plates are heated and bonded under warm pressure. A device shown in FIG. 11 was used for heating. That is, metal plate materials 101 with different properties,
102 and 103 were overlapped, passed through a heating furnace 104 consisting of a combustion furnace or an electric furnace, heated, and then pressurized by a pressure mechanism consisting of rolls to form a cladding material 106 that was fixed together. As the heating furnace 104,
Heating means using radiation, convection of hot gas, or a combination of both have been used. The heating furnace 104 had a sufficient furnace length so that all of the metal plates 101, 102, and 103 were uniformly heated.

しかしながら、従来の方法では、複数の金属板材１０１

せると接合が困難となる。D. Problems to be Solved by the Invention However, in the conventional method, a plurality of metal plates 101
, 102, and 103 are heated to a uniform temperature as a whole, if metal plates having different properties (for example, hardness) are used, joining may be difficult or inappropriate. for example,
When joining metal plates such as aluminum and steel, which have significantly different hardness or deformation resistance, the deformation resistance decreases as the temperature increases, but since both metal plates are heated to the same temperature, steel Aluminum was significantly deformed, whereas aluminum was hardly deformed. If the amount of deformation differs greatly in this way, it cannot be said to be a good rad material, and
If the pressing force is lowered in an attempt to suppress the deformation of aluminum, joining becomes difficult.
一方、上記加熱炉１０４は輻射又は熱ガスとの対流によ

充分な時間をかけて加熱するので加熱炉１０４の炉長を
長く必要とし、その占有面積を多く必要としていた。On the other hand, since the heating furnace 104 heats by radiation or convection with hot gas, the temperature of both metal plates 101 and 103 is raised efficiently, but the temperature of the central metal plate 102 is raised by heat conduction, so the temperature is not raised efficiently. It was low. In addition, all metal plate materials 1
01, 102, and 103 are heated to the same temperature over a sufficient period of time, the length of the heating furnace 104 is required to be long, and a large area is required.

Means for solving the above-mentioned problems and their operation In the present invention, in a method of laminating a plurality of metal plate materials having different hardness at room temperature and then pressurizing them to form an integrated cladding material, By selectively inductively heating at least one metal plate material, for example one with a higher hardness than the others, before or after stacking, the deformation resistance of the metal plate material that has high deformation resistance at room temperature is lowered, and multiple different metals can be combined. In this method, the plates are conveyed between pressure rolls in a state in which the difference in deformation resistance between the plates is reduced, and pressure bonding is performed. Here, by using TRC heating or LNC heating as induction heating, it is possible to select an appropriate heating method for a plurality of materials to be heated that have different properties, and it is also possible to selectively heat the materials after they are stacked. .

選ばないと有効に加熱することができないからである。FIG. 1 shows a first embodiment of the present invention. FIG. 1 shows an apparatus for manufacturing cladding material from two types of metal plate materials. That is, plate-shaped austenitic stainless steel fil and aluminum (or steel) 2 are each paid out from payout rolls 3 and 4, guided by guide rolls 5 and overlapped, and then rolled with a pressure roll 6. The clad material 8 is pressurized and joined by a machine 7 to become an integrated cladding material 8, which is then wound onto a winding roll 9. Here, the hardness of austenitic stainless steel #1ll at room temperature is Vickers hardness (
Hv) 160, the deformation resistance is extremely large,
Aluminum (or copper) has a hardness of about 40 Vickers hardness (Hv) even at room temperature, and has low deformation resistance. Therefore, if pressure is applied as is, the deformation of aluminum (or copper) will become too large. So, the book'
In Amfl'4, a TFLC heating section and a 10-id roller 11 are provided in order to heat the austenitic stainless steel 1 and lower the deformation resistance before stacking the austenitic stainless steel 1 on top of each other. This TRC heating processing part 10 medium frequency (1500~50
The austenitic stainless steel 1 is heated by TRC heating at a frequency of 0.00 Hz). The heating temperature is 250℃ during rolling.
A sufficient effect was obtained with the following. Thereafter, it is pressed with the aluminum (or steel) 2 by the rolling mill 7, but since the deformation resistance is reduced, the bonding is good. Furthermore,
The reason why TRC heating was performed as induction heating in this example is as follows. That is, the patent application filed earlier by the inventor in 1982
As shown in No. 227980 or Japanese Patent Application No. 62-227981, there is compatibility between the induction heating method, the frequency of electric power for heating, and the object, and it will not be effective unless it is selected appropriately. This is because it cannot be heated.

したようにＴＲＣ加熱加工部１０けたのである。As shown in Table 1, medium-frequency TRC heating is suitable for austenitic stainless steel flI41, which is a non-magnetic high resistivity member. Therefore, as mentioned above, the TRC heating processing area was increased by 10 digits.

12 and above and below it, carbon steels 13 and 14 are fed out from feeding wheels 15, 16 and 17, guided by guide rolls 18 and stacked in three layers, and then pressed by pressure rolls 19 to join them. Then, it becomes an integrated cladding material 20 and is wound around a winding roll 21. Here carbon fi13.1
No. 4 has a significantly high hardness at room temperature of about 160 Vickers hardness (Hv). Therefore, the carbon fR before being superimposed
LNGN thermal heating 2.23 for heating 13 and 14 is provided. These LNGN thermal heaters 2.23 are supplied with power at a frequency corresponding to the thickness of the carbon steel plates 13.14 to heat the carbon steel 13.14. As for the heating temperature, a sufficient effect was obtained at 250° C. or lower during pressurization. Thereafter, the heated carbon steels 13 and 14 whose deformation resistance has been reduced are pressed by a pressure roller 19, and are bonded well to the aluminum 12. In this example, LN is used as induction heating.
The reason why G heating was used is that, as shown in Table 1 above, LNC heating has good compatibility with carbon fi13.14, which is a magnetic material.

する。In other words, since aluminum (or copper) 12 is a non-magnetic material, it has poor compatibility with LNG heating as shown in Table 1 above.
Not heated. For this reason, aluminum (or copper) 12
is not heated even if it passes through the LNC heating section 24, and the LNGN
Carbon tR13°14 is heated by thermal heating 4.
t'! That's it. In this way, in this embodiment, induction heating is performed after stacking, so there is an advantage that only one heating unit can be used, compared to the second embodiment, in which induction heating is performed before stacking. In addition, it is better to provide a gap between each metal plate to avoid heat conduction.Also, the temperature of the aluminum (or copper) 12 rises to some extent due to the radiant heat from the upper and lower carbon steels 13 and 14.
次に、第４図を参照して第４実施例について説明する。Next, a fourth embodiment will be described with reference to FIG.

、炭素鋼２７を加熱する温度を例えば２５０℃とした。This example is a method of manufacturing a cladding material from three types of metal plate materials. That is, the non-magnetic nickel alloy 25° aluminum 26. used in this example. Regarding the hardness of carbon w427 at room temperature, carbon steel 27> nickel alloy 25)
It has to do with aluminum 26. If the hardness at room temperature is large and the deformation resistance is different, it is desirable to change the degree of heating depending on the material of the metal plate so that the deformation resistance during rolling is as uniform as possible. Therefore, a nickel alloy 25 as a non-magnetic high resistance material is heated.
LNG heating heating section 9 that heats the TltC heating section 28 of 500 to 5000 centimeters and the carbon steel 27 as a magnetic material
The temperature at which the nickel alloy 25 is heated is, for example, 200°C.
The temperature at which the carbon steel 27 is heated is, for example, 250°C.

Nickel alloy 25 and aluminum 26 heated to different temperatures in this way. When the carbon TF427 is pressed by the pressure roller 19, its deformation resistance is uniform, so that it can be bonded well. Note that the other configurations are the same as the second embodiment shown in FIG.

ものとなる。By the way, the temperature of the metal plate material conveyed between the heating section and the rolling mill decreases due to heat radiation. In particular, the amount of heat dissipated is large at both ends in the width direction of the plate material, and the temperature drop is particularly significant. For example, the temperature distribution in the board width direction at the exit of the heating section is
When the rolling mill is heated almost uniformly as shown in Figure (al), the temperature distribution at the inlet of the rolling mill decreases at both ends as shown in Figure (b), which is undesirable. Also,
If the temperature distribution in the strip width direction at the exit of the heating section is already low at both ends as shown in Figure 6 (al), the temperature distribution at the entrance of the rolling mill becomes even lower as shown in Figure 6 (bl), making it even more inappropriate. Become something.

If it is heated to about 100° C. higher, the temperature distribution at the inlet of the rolling mill becomes almost uniform as shown in the same figure (bl), and good rolling joint results can be obtained.

より良好なりラッド材を得ることができる。Instead of heating the entire material, we selectively heat it according to its properties, set the temperature during pressure bonding that is suitable for each metal plate, and selectively heat each metal plate to a different temperature. Good pressure bonding can be achieved by eliminating or reducing the difference in deformation resistance between metal plates. Therefore, it becomes easy to manufacture a good rad material by combining metal plate materials that have large differences in hardness and deformation resistance at room temperature. In addition, when heating metal plates, the temperature at both ends of the plate in the width direction is heated to a higher temperature than the other parts, and the temperature distribution in the plate width direction at the start of pressure is made almost uniform to achieve pressure bonding. By doing so, a good rad material can be obtained.
