| Shaft furnace apparatus comprising an upstanding furnace shell, and a supporting structure comprising a frame surrounding and spaced from the shell including generally horizontally disposed frame members joined end to end and being of substantial depth and having sides facing the shell, spaced legs supporting the frame, and a plurality of connector means fixed to such sides of the frame members and to the shell to support the shell from the frame, and means connected to the members forming the frame to resist tilting of the frame members about generally horizontal axes during expansion of the shell on heating of the furnace. Preferably, at least 25 percent of the weight of the furnace above the bosh portion is at all times supported by the supporting structure. If desired, the hearth portion of the furnace may be suspended below the frame and be essentially unsupported from below.
