Embodiment Construction

[0013] see figure 1 with figure 2 , these two drawings show the appearance structure of an embodiment of the tunnel furnace flue proposed by the present invention. The flue includes a main body plate 1, on the inner wall of the main body plate 1, anchor hooks 11 are arranged, the upper area of ​​the anchor hooks 11 is V-shaped, and the adjacent four anchor hooks 11 on the inner wall of the main body plate 1 are installed obliquely respectively. On the four corners of the rhombus, the heat insulation layer 2 with metal mesh is limited on the inner surface of the main drawing board part 1 by anchor hooks 11, and the surface of the heat insulation layer 2 is sprayed with refractory materials.

[0014] When making the above-mentioned tunnel furnace flue, first, press or gas-cut the surface of the plate to form elongated grooves at a predetermined distance, and make the four adjacent elongated grooves located on the four corners of the rhombus, and then the plate Bend into the ...

Abstract

The invention relates to a method for manufacturing a tunnel furnace flue, which includes: arranging elongate troughs on a surface of a plate member, then bending the plate member to a flue shape to form a main plate member, welding an anchoring hook on each elongate trough, then installing heat insulating layer on an inner surface of the main plate member, finally coating a layer of fire-resistant material on the surface of the heat insulating layer, namely making the tunnel furnace flue. The welded junction area of the anchoring hook in the tunnel furnace flue is relatively large so that the anchoring hook can be fixed on the main body panel firmly to ensure that the sprayed fire-resistant material cannot drop even if the sprayed fire-resistant material is vibrated by a transition carriage; therefore, the tunnel furnace flue can not only improve the production efficiency of a heating furnace, but also can reduce production cost.

Description

Technical field [0001] The present invention involves a method of making a tunnel flue. Background technique [0002] Because the tunnel furnace flue is a passage that transports the flames and flue gas in the furnace to the external space, and the flue is easily damaged when the erosion of flames and high -temperature gases. Therefore, in the existing technology, the tunnel furnace tobaccoThe flue of the roads or other industrial furnaces is usually made of refractory brick, and the built -in flue includes the stove wall and the top of the furnace.Due to the long time used for the masonry flue, and the hooding miles, the temperature of the tunnel furnace also has strict requirements after the tunnel furnace, so the flue of the structure of this structure will affect the yield.Because the flue is to adapt to the environment around the tunnel furnace, there are often some different types of parts of the flue, and it is very difficult for the alien parts of the masonry flue. At the...
