Abstract
The utility model discloses a furnace bottom structure of a spheroidizing annealing furnace, which mainly comprises a metal bottom plate, a ceramic fiber cotton plate, a thermal insulation brick built layer, a refractory layer and a ceramic fiber cotton blanket sequentially disposed from bottom to top. The upper surface of the refractory layer is concave spherical, the ceramic fiber cotton blanket spread over the refractor layer is also concave spherical, the concave spherical shape is matched with a convex spherical shape of the bottom face of an inner barrel of the annealing furnace, and a mark layer for indicating position of the inner barrel is arranged on the ceramic fiber cotton blanket. By the aid of the furnace bottom structure, the position of the inner barrel can be effectively indicated by the mark layer, and thereby the position of a center of the inner barrel can be guaranteed during mounting, and mounting is facilitated. The center of the inner barrel is consistent to a furnace bottom and a furnace bottom fan, so that annealing effect can be guaranteed.
