Belt-shaped furnace

The utility model relates to a belt-shaped furnace, which belongs to an industrial furnace. The technical problems to be solved include the shrinkage cracking of ceramic fiber boards under high temperature, the sinking of the setter plate, the collapse of the furnace chamber, the drop of debris and the like. The technical point of the belt-shaped furnace is that: refractory mounting boards are mounted on the walls and top of a furnace chamber, fiber felt insulating layers are fixed on the inner walls of the refractory mounting boards by rivets, a refractory layer which is formed by assembled modules is stuck on the inner walls of the fiber felt insulating layers, a setter platform is mounted on the upper part of a scissor type hydraulic lift platform, and comprises a loading platform and a setter plate, the loading platform comprises a ceramic fiber product and a plurality of corundum mullite tubes, and the furnace chamber is sealed by the stepped convex-concave seal between hard ceramic fiber boards and flexible ceramic modules. The structure of the belt-shaped furnace is firm and stable, and has the advantages of high temperature control precision, low energy consumption, clean furnace chamber and uniform temperature, and moreover, the belt-shaped furnace can be conveniently and effectively operated, and can stably operate for a long time.
