Abstract
A coolable arched roof for a high-temperature melting furnace having a furnace interior. At least the following layers are present on that side of a layer of refractory bricks, which is remote from the furnace interior: a sealing layer, which is used to seal the furnace interior against the leakage or penetration of gas; an insulation layer having a thermally insulating action; and a cooling layer, which is designed to carry a cooling fluid. The arrangement of layers results in an increased gastightness and prevents premature aging of the refractory bricks.
Claims21
A coolable arched roof for a high-temperature melting furnace having a furnace interior, the arched roof comprising:
- at least one layer of refractory bricks having a side remote from the furnace interior;
- and
- an arrangement of layers on the side of the at least one layer of refractory bricks which is remote from the furnace interior, the arrangement of layers including:
- a sealing layer arranged so as to seal the furnace interior against an escape or penetration of gas;
- an insulation layer with a thermally insulating action;
- and a cooling layer designed to carry a cooling fluid.
