2. Description of the Related Art As a cooling zone carrying roll used in a heat treatment furnace for subjecting a metal foil to a heat treatment such as annealing, one made of a metal such as stainless steel or heat resistant steel is used. However, in the case of the carrier roll formed of this kind of metal, since it has a high thermal conductivity, it was used in the process of cooling the high temperature metal foil to the temperature range of 100 ° C. after the heat treatment, especially in the cooling zone entrance side. In that case, a large amount of heat is taken from the metal foil. As a result, when the metal foil is thin, the rigidity of the metal foil is low, so that local heat shrinkage occurs, causing wrinkles in the metal foil.

However, the heat resistance is not sufficient, and the temperature is 150 ° C.
When it contacts the metal foil in the above temperature range, it may be softened and deformed, or rubber may adhere to the surface of the metal foil to impair the quality of the metal foil. Therefore, when priority is given to preventing the generation of wrinkles, it has been attempted to use a rubber-made transport roll and gradually cool the metal foil after the oxidation treatment to a region of 150 ° C. or lower.

Through experiments, the inventors of the present invention have found that wrinkles appear on the metal foil when a stainless-steel carrying roll is used, because the heat conductivity of stainless steel is large, and therefore the metal foil is cooled during the cooling process. As a result, a large amount of heat is taken from the metal foil, and as a result, the metal foil with low rigidity is locally heat-contracted. The present invention was conceived and completed based on this finding.

In the present invention, particularly in the process of cooling from the temperature range of 500 to 1200 ° C. to the temperature range of 100 ° C., the temperature of the metal foil contacting the conveying roll on the cooling zone entrance side is 150.

For that purpose, the surface layer of the transport roll is formed of a solid material satisfying the following conditions (target: one having both heat resistance similar to heat-resistant metal and thermal conductivity similar to rubber). Does not deform or deteriorate in a temperature range of 500 ° C or higher (ensures heat resistance) Reduces thermal conductivity (suppresses rapid thermal contraction) It is preferable to set the thermal conductivity to about rubber, but to improve heat resistance and durability. Since the ceramics that can be secured is suitable, it is currently about 3 kJ / mhk. In order to prevent wrinkles from occurring on the metal foil, it is necessary to set the pressure to 10 kJ / mhk or less. The porosity that can reduce the contact area with the metal foil (increase the surface porosity and suppress rapid thermal contraction) is preferably 10 to 30%. If it is 10% or less, the effect of reducing the thermal conductivity is not sufficient. If it is 30% or more, it tends to be worn. The porosity can be easily secured by forming a fiber shape that is relatively easy to form (fabrication is easy) by thermal spraying or fiberizing and winding.
