Girder construction is pushed down to walking beam formula heating furnace charging end

The utility model discloses a black strip production technical field's a girder construction is pushed down to walking beam formula heating furnace charging end, this structure includes that the heat recovery section pushes down roof beam, charging chamber and push down roof beam and straight wall steel construction, the straight wall steel construction is located furnace body flue both sides, the roof beam is pushed down to the heat recovery section and the charging chamber pushes down the top that the roof beam is located flue left and right sides furnace roof respectively, the charging chamber pushes down roof beam and heat recovery section and pushes down the roof beam and all fix through a supporting beam of top, prop up and leave one section distance between supporting beam and the straight wall steel construction, make the space that has the ventilation between the two, be favorable to the heat dissipation, also have simultaneously and to reduce the construction degree of difficulty of laying refractory material, the charging chamber pushes down roof beam and heat recovery section and pushes down the outer wall of roof beam and be equipped with the insulating layer, and the insulating layer can effectively reduce from the furnace roof transmit the inside heat of steel construction, and the pouring pull -up of having avoided invar structural distortion to lead to falls, furnace roof refractory material damages the scheduling problem.
