In order to limit the bearing wheel 3-2-3 to roll on the track 3-1-5 and avoid derailment, centering wheels 3-2-4 are also arranged on both sides of the bearing wheel 3-2-3. The centering wheel 3-2-4 is horizontally arranged and fixed on the frame bottom wall 3-1-1a of the annular furnace frame 3-1-1, and the rotating shaft is vertical; limiting plates 3-2-9 which are respectively positioned at two sides of the supporting wheel 3-2-3 are arranged on the furnace bottom frame 3-2-1; the centering wheels 3-2-4 on the two sides respectively limit the outward moving range of the limiting plates 3-2-9 on the two sides, so that the radial inward and outward moving range of the furnace bottom lining 3-2-7 is limited, and the furnace bottom lining can reliably rotate and does not derail.
