<p>For limiting heat loss from hot material such as steel bars and slabs between hot rolling operations, displaceable chambers (92 or 144) are provided for holding and transferring the hot material (S) between processing stages. The chamber forms a heat-insulating enclosure with one or both ends openable for the insertion and removal of the material. For use in existing rolling mills, the chamber (92) can be arranged to be displaced along the roller tables. Alternatively, the chamber (144) can be incorporated in a railcar (146) that moves between spaced stations (150,152) in the course of processing the material. Within the chamber, means (120 or 158, 160 or 178) are provided for holding the hot material spaced above the lower insulating wall.</p> |
