A transport apparatus comprising a plurality of metal rolls for transporting a hot heavy material is disclosed. Each roll is provided with a desired number of ring-like circumferential grooves which are filled with a heat insulating material, and the grooves of each roll are staggered with respect to the grooves of the adjacent rolls. In accordance with the present invention, the temperature drop of the hot heavy material during the transportation can be greatly reduced, and in addition, the temperature fluctuation in both the sectional direction and the longitudinal direction of the hot heavy material is sharply decreased. The invention contributes considerably to the realization of the direct rolling process on an industrial scale. |
