Abstract
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). A furnace exterior side of the refractory bricks and a furnace interior side of a cooling water pipe are overlapped in a vertical direction of the water-cooled panel, and the cooling water pipe is provided in between an upper and lower side of refractory bricks.

A cast iron, cast steel or copper casting type water-cooled panel for installation in a wall and roof of an electric-arc furnace, the water-cooled panel for the wall and roof of an electric-arc furnace comprising, a casting and embedded in the casting refractory bricks arrayed in multiple regularly spaced rows to be exposed at their ends on a furnace interior side, a furnace exterior side of the refractory bricks and a furnace interior side of a cooling water pipe are overlapped in a vertical direction of the water-cooled panel, and the cooling water pipe is provided in between an upper and lower side of refractory bricks.
A cast iron, cast steel or copper casting type water-cooled panel for installation in a wall and roof of an electric-arc furnace, the water-cooled panel for the wall and roof of an electric-arc furnace comprising multiple regularly spaced rows of slits for inserting refractory bricks from a side of the panel opposite a furnace interior side and at least one cooling water pipe embedded between the rows of slits.
A water-cooled panel for a roof of an electric-arc furnace constituted as a casting type panel having multiple refractory bricks and one or more cooling pipes for passing cooling water embedded in cast iron, cast steel or copper,
- the water-cooled panel comprising a casting and refractory bricks embedded in the casting that project on a furnace interior side,
- each refractory brick having a middle portion disposed between an end of such refractory brick projecting on the furnace interior side and a portion thereof embedded in the casting,
- said middle portion having a width, with said projecting end and said portion embedded in the casting having a shape larger than the width of said middle portion, and
- slag catchers for retaining slag adhering to the furnace roof provided on a surface of the casting on the furnace interior side.
