A metallurgical furnace including a refractory, which may include an inner layer, including bricks of a first type having a heat dissipation thickness, and bricks of a second type having a greater sacrificial thickness and protruding towards the furnace space. The furnace may include a force exerting member for contracting a segmented outer shell around the refractory, inward, as the refractory contracts when cooling. The force exerting member may include a tension member. The furnace may include a vertical compression member for exerting a compressive force upon the refractory, vertically compressing the refractory as it contracts. The furnace may include a cooling system, including a sleeve surrounding a layer of heated air, and air displacement members for displacing away the heated air. The furnace may include a roof, having suspension members extending therethrough, supporting an inner mesh, the inner mesh supporting insulating material. The furnace may also include an electrode seal having a plurality of shoes biased against the electrode(s). |
