摘要： 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.

摘要： A system for supporting and cooling a furnace roof comprised of refractory bricks comprises a plurality of roof support members extending across the furnace and being supported from above the furnace roof. The support members are provided with internal channels for circulation of a cooling fluid, and are provided with side surfaces adapted to support rows or refractory bricks between adjacent roof support members. The system eliminates the need to suspend individual bricks from above the roof, and provides simultaneous support and cooling of the roof structure.
摘要翻译：用于支撑和冷却由耐火砖组成的炉顶的系统包括跨过炉子延伸并从炉顶上方支撑的多个屋顶支撑构件。支撑构件设置有用于循环冷却流体的内部通道，并且设置有适于在相邻屋顶支撑构件之间支撑行或耐火砖的侧表面。该系统不需要从屋顶上悬挂单块砖，同时提供屋顶结构的支撑和冷却。

摘要： A cooled roof for electric arc furnaces (20) or ladle furnaces (29). The roof being used as a covering element and including a cooling system comprising tubes fed with cooling fluid. The roof including at least a central aperture (25) for the positioning and movement of the electrodes (30) and at least a peripheral aperture (14) for the aspiration and discharge of fumes. The aperture (14) being connected to intake systems. The roof including two single-block cooling structures, inner (1) and outer (12), consisting of respective bent tubes (15, 16) developing according to adjacent and superimposed rings or spirals. The inner (11) and outer (12) cooling structures being associated with one another at least in correspondence with the respective bases facing towards the inside of the furnace (20, 29). Between the inner cooling structure (11) and the outer cooling structure (12) there being defined an annular interspace (13) in which the fumes circulate in an annular direction and slow down. The annular interspace (13) communicating with the peripheral aperture. The inner cooling structure (11) including fume-transit interstices connecting the inside of the furnace (20, 29) with the annular interspace (13).
