WATER-COOLING PANEL FOR FURNACE WALL AND FURNACE COVER OF ARC FURNACE

摘要

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. <IMAGE>
