れる。2. Description of the Related Art In recent years, an electromagnetic heating cooker of a type in which a cooking vessel itself is directly heated by Joule heat by an induced current has been widely used. The reason why this electromagnetically heated cooker is widely used is that it is considered to be relatively safe because a bare heater is not required, and it is also considered that the supply of combustion air and the generation of combustion exhaust gas are performed. It is easy to handle because no exhaust is required.

Generally, a method of indirectly detecting the temperature of the cooking container placed on the top plate by a temperature detector installed on the back surface of the top plate and controlling the temperature is adopted. A time lag occurs in temperature detection, and overheating or overcooling is likely to occur. Therefore, it has been pointed out that it is difficult to accurately maintain the cooking container at an appropriate temperature at which the food is deliciously cooked.

−スの合金等が知られている。Japanese Patent Application Laid-Open No. 4-220990 discloses a pot for an electromagnetic cooker in which the pot body is made of a non-magnetic metal and the bottom of the pot is a "thermosensitive metal having a Curie point (magnetic transformation point)". A heat-generating portion made of the above material has been proposed. Here, the temperature-sensitive metal having a Curie point becomes non-magnetic when the temperature of the metal exceeds the Curie point due to an increase in temperature, and does not generate heat due to the induced current. When the temperature is lower than the above range, heat is generated by an induced current. Therefore, if the electromagnetic cooker pot is configured as described above, the pot itself can control its own temperature, and the temperature of the pot can be controlled with high accuracy without providing a temperature sensor. As a practical temperature-sensitive metal having a Curie point for a temperature control member, an Fe-based alloy such as a Fe-Ni-Cr-based alloy and a Ni-based alloy are known.

In addition to the above, there was a disadvantage in the production from the point of view, and the dissatisfaction remained about the degree of heat flow to the whole pot.

Although it is thought that the problem of heat circulation pointed out in the skillful pot is solved, a strong laminate of a non-magnetic metal and a temperature-sensitive metal having a Curie point can be industrially manufactured without impairing the properties of the temperature-sensitive metal. It is extremely difficult to produce a stable and low-cost electromagnetic cooker pot at a low price, so it is necessary to laminate a non-magnetic metal with a temperature-sensitive metal having a Curie point. It was necessary to establish a technology for mass-producing the body. In other words, the temperature-sensitive metal having a Curie point becomes indistinct depending on the treatment and the performance as a temperature-sensitive metal becomes inferior depending on the treatment. If the lamination bonding is not sufficient, local current concentration occurs when used as a temperature control member such as a pan for an electromagnetic cooker, causing a problem that uniform heating cannot be achieved.

A method of joining a metal to form a laminate by brazing "is disclosed. However, since the clad material joined by brazing has not achieved strong metal bonding, the joining strength is low, and peeling is likely to occur at the joining interface. Then, if peeling occurs even if it is partial, if this is used for a temperature control member such as a pan for an electromagnetic cooker, local current concentration occurs as described above, making uniform heating difficult as a whole. Become. Therefore, it has been considered that the method of producing a clad material of a non-magnetic metal and a temperature-sensitive metal having a Curie point by brazing is not practical for producing, for example, a material for a pan for an electromagnetic cooker.

It has been strongly desired to establish a technology that can mass-produce clad materials for temperature control members of high quality with a "temperature-sensitive metal having a point", but by controlling the heat generation by induction current by laminating a temperature-sensitive metal having a Curie point. The “cladding material for temperature control members of non-magnetic metal and temperature-sensitive metal” made possible is expected to be in great demand especially for electromagnetic cookers.
Aluminum (including aluminum alloy), which has a wide range of uses as a cooker, was considered to be the most suitable material as a nonmagnetic metal as a mating material on which a temperature-sensitive metal having a point is laminated.

The aim was to establish a means for mass-producing the compound stably and at low cost.

は望めない。Means for Solving the Problems The present inventors have conducted intensive studies in order to achieve the above object, and as a result, have obtained the following findings a) to d). a) Conventionally, explosive bonding, rolling bonding, plating, thermal spraying, etc. have been known as methods of manufacturing a laminated material in which dissimilar metals are laminated and joined. Among these, the explosive method has a high manufacturing cost. For example, it is not suitable as a means for adjusting the material for an electromagnetic heating cooker, and the plating method or the thermal spraying method cannot sufficiently increase the thickness of the plating layer or the thermal spray layer. This method is not suitable as a means for adjusting the material of the vessel, and it is difficult to make the thickness of the plating layer or the sprayed layer formed uniform. Even if a “laminate with metal” is manufactured, accurate temperature control cannot be expected.

ることができない。B) On the other hand, the roll joining method can mass-produce a clad material having an arbitrary thickness and a uniform layer thickness at a relatively low cost, so that “aluminum and curie” are used as temperature control members.
It is considered that it is suitable as a means for producing a laminated material with a temperature-sensitive metal having a point. However, a temperature-sensitive metal having a Curie point becomes unclear when a large strain is given by rolling. There is a problem, and a clad material satisfactory as a temperature control member cannot be obtained by simply applying the rolling joining method.

抑えることができる。C) However, when a temperature-sensitive metal having a Curie point is rolled and heated to adjust the rolling temperature to a specific region, even if the rolling is performed at a relatively high rolling reduction, the residual strain is reduced. It is not so large, so that the inconvenience that the Curie point becomes unclear by rolling can be suppressed.

る。D) In addition, when the aluminum and the temperature-sensitive metal having the Curie point are roll-joined, the rolling temperature of the temperature-sensitive metal having the Curie point is adjusted to the specific region, and the aluminum is also heated. When the two materials are joined and rolled under the condition that the rolling temperature of these two metals and the total rolling reduction expressed by the following equation (2) satisfy a specific relationship, the rolling load and the rolling reduction are relatively low. Thus, a strong metal bonding is achieved even with a wide material, and a high-performance temperature control member having a "temperature-sensitive metal layer having a clear Curie point" can be obtained.

Cladding Rolling Temperature of "Temperature Sensitive Metal Having a Point" As described above, the "rolling temperature" in the present invention is "the temperature of the raw material measured within 10 seconds before the raw material is bitten by the rolling roll". The rolling temperature of "aluminum" as a clad material is lower than 300 DEG C., or the rolling temperature of "thermosensitive metal having a Curie point" is 25.
If the temperature does not reach 0 ° C., a high pressure is required to obtain sufficient bonding strength. However, when rolling under high pressure, a large strain is imparted to the temperature-sensitive metal having a Curie point, so that the metal remains and the Curie point becomes unclear, so that performance as a temperature control member cannot be obtained. On the other hand, if the rolling temperature of “aluminum” exceeds 500 ° C. or the rolling temperature of “thermosensitive metal having a Curie point” exceeds 450 ° C., excessive heat may be applied to the aluminum surface or the surface of the thermosensitive metal having the Curie point. The bonding strength is reduced due to the formation of an oxide film, and the performance as a temperature control member is also deteriorated.

To 500 ° C, and the rolling temperature of the temperature-sensitive metal having a Curie point was limited to 250 to 450 ° C.
It has been confirmed that these temperature ranges are common conditions for avoiding the above-mentioned disadvantages regardless of the type of "aluminum material" or the type of "temperature-sensitive metal having a Curie point".

響することはない。The temperature of the material heated during the clad rolling is reduced by heat radiation to the atmosphere and heat to the transport roller before being bitten by the rolling rolls. "Material temperature immediately before the roll gap of the rolling mill (material temperature within 10 seconds before biting into the rolling roll)" is measured and grasped. (5 to 15 ° C.), and does not significantly affect the clarity of the Curie point of the temperature-sensitive metal or the joining property of the clad material.

Under the condition of Ta + 10.37 ”, sufficient bonding strength as a temperature control member between“ aluminum ”and“ thermosensitive metal having a Curie point ”cannot be obtained, while the total rolling reduction r is“ Logr> (−5.55 × 10 −5 × Tk + 0.275) logTk + 0.227
Under the condition of "logTa + 0.122", even if the material is heated to the above-mentioned rolling temperature range, a large strain is given to the "temperature-sensitive metal having a Curie point" and remains, so that the Curie point becomes unclear, The obtained clad material is still unsuitable as a temperature control member.

とができる。However, from the viewpoint of almost eliminating the adverse effect on the clarity of the Curie point due to the residual strain, the total reduction ratio r in the clad rolling is adjusted to a range of “5% or more and less than 10%”. Is preferable. If possible, the rolling reduction of the "temperature-sensitive metal having a Curie point" at the time of clad rolling is preferably adjusted to a range of 2 to 15%. This is because, by setting the reduction rate of the temperature-sensitive metal at this time to 2% or more, it is possible to further stably secure the strength of the clad material. On the other hand, when the reduction rate of the temperature-sensitive metal exceeds 15% at the time of clad rolling, the temperature sensitivity is increased. This is because there is a concern that the amount of strain given to the metal increases and the Curie point becomes unclear. Adjustment of the rolling reduction of the “thermosensitive metal having a Curie point” during clad rolling can be performed by controlling the tension of the material as in the case of clad rolling of a general material.
