<p>A water-cooling panel for the furnace wall and furnace cover of an arc furnace that is capable of securing a service life equal to or greater than that of a water-cooling panel of steel plate weld construction, steel piping construction, copper casting or steel plate weld construction having no refractory material on the inner surface of the furnace, while reducing the heat loss and the power used to feed cooling water and without having to replace the water-cooling panel body due to the consumption of the refractory bricks. The panel comprises refractory bricks (2) disposed in a plurality of regularly spaced rows to expose their end surfaces to the inner wall surface of the furnace, and cooling-water piping (3) installed between the rows of refractory bricks (2), the refractory bricks and the piping being integrated by inserting. A taper (8) may be formed so as to make the width of those end surfaces of the refractory bricks (2) that are associated with the inside of the furnace, smaller than the width of the opposite end surfaces, or a buffer (7) may be installed between contact surfaces of the refractory bricks (2) and the cast article, or part of the inner surface of the furnace may be formed convex.</p> |
