    • A water-cooled panel for the furnace wall and furnace roof of an electric-arc furnace is provided that reduces power required for heat loss and cooling water supply and, with no need to replace the main water-cooled panel unit owing to wearing of refractory bricks, also achieves a service life equal to or longer than a steel plate welded structure, a steel pipework structure, a copper casting or a water-cooled panel of a steel plate welded structure having no refractory material on the furnace inward side.
      A water-cooled panel for the furnace wall and furnace roof of an electric-arc furnace is integrally fabricated of refractory bricks arrayed on the furnace inner wall in multiple regularly spaced rows to be exposed at the end surfaces and cooling water pipes installed between the rows of refractory bricks (2) and refractory bricks (2). The refractory bricks (2) have a taper (8) can be tapered so as to make the width of the end faces on the furnace inner side smaller than the width of the end faces opposite side of the furnace a cushioning material (7) can be provided between the contact surfaces of the refractory bricks (2) and the casting, and/or part of the inner surface of the furnace can be formed to be convex.
    • 提供了用于电弧炉的炉壁和炉顶的水冷面板,其减少了热损失和冷却水供应所需的功率,并且由于耐火材料的磨损而无需更换主水冷面板单元 砖也可以实现等于或长于钢板焊接结构,钢管道结构,铜铸造或在炉内侧不具有耐火材料的钢板焊接结构的水冷板的使用寿命。 用于电弧炉的炉壁和炉顶的水冷面板整体地制成耐火砖,该耐火砖排列在多个规则间隔排的炉内壁上,以暴露在端面处,并且安装在排之间的冷却水管 耐火砖(2)和耐火砖(2)。 耐火砖(2)具有锥形(8)可以是锥形的,以使得炉内侧的端面的宽度小于炉子的相对侧的宽度,缓冲材料(7)可以 设置在耐火砖(2)的接触表面和铸件之间,和/或炉的内表面的一部分可以形成为凸形。
