ABSTRACT:
A furnace panel for use in an arc furnace is disclosed having a cast iron block with first and second surfaces and with a cooling circuit located therebetween. The block has at least one anchoring member projecting outwards from its second surface for retaining the block to a wall of the furnace. The panel further includes steel studs embedded in the cast iron block which project outwards from the first surface and which have a profile which enhances containment of molten slag against the first surface to prolong the life of the block. As the molten slag is splashed onto the first surface of the block, the steel studs protrude outward similar to fingers on a hand, and catch the slag and retain it until it momentarily solidifies. Once the slag has solidified, it acts as an insulating layer to prevent erosion of the block by the further impingement of additional molten slag.
