ABSTRACT:
Screens for limiting heat losses from heated material, e.g. bars and slabs in rolling mills. Screens are provided in the form of strings of heat insulating bodies composed of metal shells containing insulating material. These screens may form curtains and/or covers for the hot material. Containing chambers for the hot material may be provided with such strings of elements and the chambers may also comprise structure for limiting heat conduction losses through the material supports therein. The screens may be collapsed over the hot material thereby completely surrounding and insulating the material from loss of heat. A displaceable chamber installation may also be provided for limiting heat loss when holding and transferring hot material between processing stages.
