Abstract
A DC arc furnace electrically conductive hearth brickwork wear lining has metal electrical conductors extending through it which are molten for their upper portions when working and by electromagnetic flowing can erode the bricks of the brickwork. To prevent this erosion resistant refractory shields are positioned so as to shield the bricks from such flows.
