Abstract
The invention relates to a manufacturing method of a mesh-belt heating furnace with a cooling muffle, which is characterized in that an inner muffle welded junction (7) of the cooling muffle is not wrapped by a water jacket (7) but exposed to atmosphere. The inner muffle forms a sealing member by welding an upper half inner muffle (1) and a lower half inner muffle (2).An upper water jacket (3) is arranged on the upper half inner muffle (1) above the welded junction (7) of the upper and the lower inner muffles, and a lower water jacket (4) is arranged on the lower inner muffle (2) below the welded junction (7) of the upper and the lower inner muffles. In addition, a circulating pipe (6) is communicated between the upper water jacket (3) and the lower water jacket (4), and support rods (5) are welded in the water jackets. The manufacturing method of the cooling muffle can prevent the cooling water from contacting with the welding seam of the inner muffle, thus preventing the cooling water from damaging the protective atmosphere of the inner muffle by leaking into the inner muffle through the welding seam, and preventing the cooling workpiece from oxidation.
Description
Technical field
The invention belongs to a kind of preparation method of refrigeration muffle of industrial heating furnace, particularly the net belt type heating furnace has the preparation method of the refrigeration muffle of cooling.
Background technology
Net belt type protective atmosphere continuous braze welding stove is widely used in other heat treatment of soldering, annealing of parts such as the stainless steel, carbon steel, brass, red copper of industries such as electronics, automobile, air conditioner refrigerating, Aero-Space etc., also is applied to sintering, reduction of powder metallurgy etc.Workpiece changes cooling over to after heating under protective atmosphere, what refrigeration muffle generally adopted is double-deck water-cooling structure, is welded by the steel plate bending.Internal layer claims Nei Mafu again, and skin claims water jacket again, passes to cooling water between Nei Mafu and water jacket, by the heat conduction workpiece is cooled off.Because what Nei Mafu adopted is steel plate bending Welding Structure; therefore cooling water directly contacts the weld seam of Nei Mafu; though the weld seam of welding is through the sealing leak detection; but cooling water still can infiltrate into the inside of Nei Mafu by weld seam; destroyed the protective atmosphere in the refrigeration muffle, made the cooling workpiece produce oxidation.
Summary of the invention
The objective of the invention is to design a kind of preparation method of refrigeration muffle, it makes cooling water not contact the welded seam of Nei Mafu, thereby makes cooling water not make the cooling workpiece not produce oxidation by welding seam leakage to the protective atmosphere that Nei Mafunei destroys Nei Mafunei.
Technical scheme of the present invention is the preparation method of a kind of refrigeration muffle of design, and the Nei Mafu weld of refrigeration muffle is not wrapped up by water jacket, and the weld of Nei Mafu is exposed in the atmosphere.
Described Nei Mafu, first Nei Mafu and second Nei Mafu welding constitute a seal, on first Nei Mafu above the weld of Nei Mafu up and down, a upper water sleeve is arranged, on second Nei Mafu below the weld of Nei Mafu up and down, a lower water jacket is arranged, be communicated with circulating water pipe between upper water sleeve and the lower water jacket, be welded with brace rod in the water jacket.
Described upper water sleeve is a metal material and the upper surface seal welding of first Nei Mafu of the weld top of Nei Mafu up and down constitutes; Described lower water jacket is a metal material and the upper surface seal welding of second Nei Mafu of the weld below of Nei Mafu up and down constitutes.
Advantage of the present invention is: the isolation technics that adopts Nei Mafu and water jacket welded seam; just the welded seam of Nei Mafu does not contact with water jacket; cooling water just can not leak in the refrigeration muffle like this; be not destroyed yet, thereby guarantee heating, cooled workpiece light with regard to the protective atmosphere that guarantees refrigeration muffle.To the stainless workpiece of heating cooling,, can not finish last bright technique requirement if do not adopt such structure.
Description of drawings
The present invention will be further described below in conjunction with the embodiment accompanying drawing.
Fig. 1 is the example structure schematic diagram.
Among the figure: 1, first Nei Mafu; 2, second Nei Mafu; 3, upper water sleeve; 4, lower water jacket; 5, brace rod; 6, circulating water pipe; 7, weld; 8, cooling water.
The specific embodiment
Embodiment as shown in Figure 1, the Nei Mafu weld 7 of refrigeration muffle is not wrapped up by water jacket, making up and down, the weld 7 of Nei Mafu is exposed in the atmosphere.It is divided into upper and lower two water jackets with the water tank of original refrigeration muffle, weld 7 and the welding of Nei Mafu outer surface that water jacket staggers Nei Mafu, upper and lower water jacket adopts circulating water pipe 6 to be communicated with, with 8 circulations of the cooling water between the Nei Mafu about guaranteeing, and make upper and lower water jacket on the water route, become as a whole.Specific implementation is that Nei Mafu constitutes a seal by first Nei Mafu 1 and second Nei Mafu 2 welding, on first Nei Mafu 1 above the weld 7 of Nei Mafu up and down, a upper water sleeve 3 is arranged, on second Nei Mafu 2 below the weld 7 of Nei Mafu up and down, a lower water jacket 4 is arranged, be communicated with circulating water pipe 6 between upper water sleeve 3 and the lower water jacket 4.Upper water sleeve 3 is to constitute with the upper surface seal welding of steel plate with first Nei Mafu 1 of weld 7 tops of Nei Mafu up and down.Lower water jacket 4 also is to constitute with the upper surface seal welding of steel plate with second Nei Mafu 2 of weld 7 belows of Nei Mafu up and down, is welded with brace rod 5 in the water jacket, is subjected to hydraulic pressure to play bag with waterproof jacket.
Elder generation is with upper and lower Nei Mafu and upper and lower water jacket blanking bending during making, then earlier with upper and lower Nei Mafu welding combination, again the brace rod between Nei Mafu and the water jacket 5 is welded on the outer surface of Nei Mafu, after the scarfing cinder upper and lower water jacket and upper and lower Nei Mafu are carried out assembly welding, weld circulating water pipe 6 between the upper and lower water jacket by Fig. 1, at last flange is welded in the refrigeration muffle two ends.
Because this refrigeration muffle; it makes cooling water 8 not contact the weld 7 of Nei Mafu up and down; and water jacket and brace rod 5 and circulating water pipe 6 all are the surfaces that is welded in upper and lower Nei Mafu material; thereby make cooling water 8 not destroy the protective atmosphere of Nei Mafunei to Nei Mafunei, so the cooling workpiece does not produce oxidation by welding seam leakage.
