Description
Technical field
The present invention relates to stainless steel welded pipe online treatment device, be specifically related to the online bright solid solution machine of stainless steel welded pipe.
Background technology
In the production process of stainless steel welded pipe, welded tube is to be rolled by flitch to be welded, and causes Carbide Precipitation after welding, and lattice imperfection descends the stainless steel corrosion resisting property.Stainless steel corrosion resisting property after solution treatment can return to optimum regime, so there is the stainless steel tube of two kinds of common states in present market, a kind of is the shell of not solid solution, and another kind is the solid solution pipe.In prior art, when needs carry out solution treatment to stainless steel welded pipe, the solid solution machine that comprises solid solution furnace 2 and frame 1 in the end setting of belt sander, concrete structure is referring to Fig. 1 and Fig. 2, and the solid solution furnace 2 that the stainless steel welded pipe after the belt sander polishing directly enters the solid solution machine after out from belt sander carries out solution treatment; When not needing stainless steel welded pipe is carried out solid solution, the frame 1 that needs to be connected with solid solution furnace 2 is dismantled, and in the time of need to reusing the solid solution machine, then the frame 1 that will be connected with solid solution furnace 2 is loaded onto again; Waste the time greatly, reduced working efficiency; In addition, on solid solution furnace, quartz glass tube also breaks up than being easier to, and must reinstall quartz glass tube just in case break up, and increases beyond doubt production cost, reduces production efficiency.
Yet solution treatment has two kinds aborning, and a kind of is bright solid solution, and a kind of is black solid solution (heating water-cooled in air).
the light solid solution is that stainless steel welded pipe is heated to 1080 ℃ of up and down, reduces heat is to room temperature in being full of the burner hearth of hydrogen, the solid solution furnace that stainless steel light of the prior art solution treatment is adopted is referring to Fig. 6 and Fig. 7, this solid solution furnace comprises the first ring seat 11, the second ring seat 12, the 3rd ring seat 13, be provided with heating zone 8 between the first ring seat 11 and the second ring seat 12, the second ring seat 12 is provided with gas supply area 10, be provided with cooling zone 9 between the second ring seat 12 and the 3rd ring seat 13, gas supply area 10 is provided with temperature measuring set 16 and gas inlet 15, after hydrogen enters arrival the second ring seat 12 from gas inlet 15, enter heating zone 8 and cooling zone 9 from the two ends of the second ring seat 12, cooling zone 9 is provided with the first cold water admission port 14 and the second cold water admission port 17, and cold water enters after cooled hearth 20 stainless steel welded pipe of the inside is cooling.Stainless steel welded pipe 25 enters from the entrance 26 of the first ring seat 11, after the heating of heating zone 8, passes the second ring seat 12 and enters cooling zone 9, at last from the outlet 27 of the 3rd ring seat 13 out.
Heating zone 8 comprises quartz glass tube 18 and is centered around the load coil 19 of quartz glass tube 18 outside surfaces, after ring seat is inserted at the two ends of quartz glass tube 18, left end is connected with the first ring seat 11 by the first fastening piece 22, and right-hand member is connected with the second ring seat 12 by the second fastening piece 23; Be provided with the first sealing groove 21 between the left end of quartz glass tube 18 and the first ring seat 11, the cross section that is provided with the second sealing groove 24, the first sealing grooves 21 and the second sealing groove 24 between its right-hand member and the second ring seat 12 is rectangle, placing graphite pad in sealing groove.
During installation, first graphite pads is enclosed within the two ends of quartz glass tube, again quartz glass tube is inserted ring seat, after insertion, with fastening piece, quartz glass tube and ring seat are fixed, in the time of fixedly, fastening piece is toward Glass tubing end face and ring seat junction crush seal pad, because the height of the sealing groove both sides between quartz glass tube and ring seat is identical, the sealing effectiveness of Glass tubing end face and ring seat junction is undesirable, easily gas leakage; Hydrogen in burner hearth, is lighted all and can be produced blast when the volume of institute's hydrogen in air accounts for the 4.0%-74.2% of mixed volume in case leakage contacts with the air in the external world, and this volume fraction scope is limits of explosion; There is potential safety hazard, if blast, also can damages machine.
Summary of the invention
