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.
Claims24
A heat insulating element having a hollow body comprising a thin-walled metal shell, a planar fin projecting outwardly from said shell, a heat-insulating filling of fibrous ceramic material within said shell, and means for connection with similar elements in a string of elements to form a suspended heat insulator.
A string of heat insulating elements, each of the elements having a hollow body comprising a thin-walled metal shell, a planar fin projecting from said shell, a heat-insulating filling of fibrous ceramic material within said shell, and flexible means connecting the elements in series to suspend depending one below another.
A heat insulating enclosure for insulating a mass of hot material in said enclosure, comprising:
- means for supporting said mass in said enclosure;
- a cover for said enclosure;
- means for mounting said cover above said mass;
- a series of heat-insulating elements for insulating said mass;
- flexible mounting means for said elements attached to said cover;
- the flexible mounting means suspending said series of elements at different and separated positions below the cover in relation to a horizontal plane passing through at least one of the elements, said series of elements also extending in mutually transverse horizontal directions, whereby said elements form a heat-insulating covering for at least an upper surface of said hot mass, at least some of the elements of said series being grouped together in the form of string of elements, each said string having a first end attached to the cover to suspend the string from said end, and each of at least a plurality of said strings having a second end opposite said first end and also attached to the cover to suspend the string between both said ends.
A heat insulating enclosure for insulating a mass of hot material in said enclosure, comprising:
- means for supporting said mass in said enclosure;
- a cover for said enclosure;
- means for mounting said cover above said mass;
- a series of heat-insulating elements for insulating said mass;
- flexible mounting means for said elements attached to said cover;
- the flexible mounting means suspending said series of elements at different and separated positions below the cover in relation to a horizontal plane passing through at least on the of the elements, said series of elements also extending in mutually transverse horizontal directions, whereby said elements form a heat-insulating covering for at least an upper surface of said hot mass, said series of elements being grouped together in the form of strings of elements, said strings comprising first and second series, the first series of strings being disposed in a central region of the cover and each string of said first series having opposite ends attached to the cover to depend in a catenary therefrom, the second series of strings being disposed laterally outwardly of said central region and depending vertically therefrom.
