When the inner part of the existing heating furnace has high temperature, the temperature of a furnace housing is also high, and the existing heating furnace can not satisfy the people's needs. The heating furnace is characterized in that when a furnace body is heated, the temperature of the furnace housing is still low. The utility model has the mainly structural scheme that the outer layer of a heat insulating furnace liner is provided with an air heat insulating layer, and a furnace bottom is provided with an axial fan which conducts the forced cooling to the furnace housing. |
