摘要：
An electric arc furnace for steel making includes a shell portion and a separate furnace bed portion made, the shell portion having a plurality of water-cooling boxes, instead of refractory bricks, along its inner circumferential surface, and the furnace bed portion being made slightly larger in outside diameter than the shell portion, the two portions being separably combined into a furnace.
