the utility model provides a double-deck stove of folding for hot dip galvanizing steel sheet heating, includes the base, the heating furnace body is installed at the top of base, be fixed with the resistant firebrick that a plurality of equidistance were arranged along the length direction of heating furnace body between the both sides inner wall of heating furnace body, the guide roll of height interval arrangement is all installed to resistant firebrick's top and bottom, the galvanized steel sheet has been placed in the roll on the guide roll, it has the heating pipe that two rows of equidistance were arranged to peg graft on the inner wall of heating furnace body, and two rows of heating pipes all are located resistant firebrick's below, and two rows of heating pipes are located the upper and lower both sides of galvanized steel sheet respectively, the furnace gate is all installed at the both ends of heating furnace body.
Preferably, the galvanized steel sheet is located between the guide rollers arranged in a high-low mode, and the thickness of the galvanized steel sheet is 0.5-3 mm.
Preferably, the side of the exhaust pipe is provided with a dust cover through a bracket.
Compared with the prior art, the beneficial effects of the utility model are that:
1. The utility model can divide the interior of the heating furnace body into an upper section and a lower section through the refractory bricks which are arranged in the horizontal equidistance, through the gaps between the adjacent refractory bricks, the heat below the refractory bricks is partially transferred to the upper parts of the refractory bricks, because the galvanized steel sheet moves on the guide roll, the galvanized steel sheet firstly passes through the guide roll below the refractory bricks and then passes through the guide roll above the refractory bricks, after the galvanized steel sheet is firstly heated at high temperature below the refractory bricks, the galvanized steel sheet can be continuously heated above the refractory bricks, on the premise of the same production efficiency, the galvanized steel sheet can be heated more, a better effect is achieved, the upper surface and the lower surface of the galvanized steel sheet can be synchronously heated by the two rows of heating pipes, the heating is more uniform, the smoothness after galvanization is improved, the energy consumption is reduced, the stability of Brinell hardness and tensile strength in the annealing process is effectively controlled, and the product yield is improved;
2. The utility model discloses an open the air exhauster, through the adjustable air current air output of electric butterfly valve, can more realize below heat and the thermal flow in top like this to control inside temperature.
