To provide an apparatus and method for clamping a product to be heat-treated by which an unreasonable load is not applied to the product in the case of applying the load for a curving and protruding the product in a prescribed direction by a plurality of clamping means arranged in the longitudinal direction of the product.
The product 10 to be heat-treated is provided with: a heat treating range for performing the heat treatment, where the product is heated by a heating device arranged at the one side in the direction crossed orthogonally to the longitudinal direction X and the width direction Y, and then cooled by a cooling device arranged at anther side to perform the heat treatment; and a non-heat treatment range where the heat treatment is not performed. Thus, the plurality of clamping means 222,223, which are arranged in the longitudinal direction X for applying the load for curving and protruding the product 10 in the one side are controlled by a controllrt 240 by clamping at the non-heat treatment range so that the order for clamping the non-heat treatment range is made in the order of the longitudinal direction X.
