A COOLING PANEL

摘要

A cooling panel which is intended to be positioned at the slag line of a tiltable steel-smelt arc furnace of the kind which is fitted with three electrodes, and in which the three electrodes give rise to three regions which are subjected to extensive wear as a result of the forces generated by mutual repellation of the arcsproduced by the electrodes. The cooling panel is mounted in the slag line at a location within the aforesaid three regions and includes a first part (1) which is provided with cooling fins and which protrudes through the furnace wall and in towards the furnace space, and a second, outer part (2) which projects outwardly from the furnace-wall and which is provided with channels (3) for the passage of panel-cooling water, which thus also cools the aforesaid three regions where wear is extensive. The panel is preferably made of copper and is combined with MgO-C-brick and refractory material of high thermal conductivity.
