Abstract
The invention discloses a manufacture method of the metal carrier for a catalyst. The metal carrier is provided with a plurality of honeycomb-shaped internal cores (3) of air holes (2) extended along the axis line direction and a cylindrical or non-cylindrical shell (4) coated at the circumference of the honeycomb-shaped internal core (3). The invention is characterized in that the internal wall of the cylindrical or non-cylindrical shell (4) is roll welded the nickel-based strip-shaped brazing material (5), the honeycomb-shaped internal core (3) is then sleeved in the shell (4) and is finally brazed by a brazing furnace. By adopting the method, the welding strength between the shell and the internal core is ensured, the process is simplified, and the manufacturing cost is reduced.
Description
Technical field
The present invention relates to a kind of manufacture method that is used to carry the metallic carrier of purifying motor tail-gas catalyst.
Background technology
Metallic carrier is because cellular inner core is to adopt different materials with shell, and cellular inner core adopts siderochrome aluminium, and shell adopts high temperature resistant stainless steel; Cellular inner core and outer casing thickness are inconsistent, and cellular inner core thickness is 0.02～0.1mm, outer casing thickness 1～2mm.In use, because temperature is higher, can reach more than 900 ℃, reasons such as two kinds of material thermal expansion coefficient differences and thermal creep, under the long-term operating position, cellular inner core easily separates with shell, the phenomenon that cellular inner core is blown out can occur in practice from shell, causes catalyst converter to scrap.
How improving the bond strength of cellular inner core of metallic carrier and shell, is the key problem in technology of making metallic carrier.
Patent CN93108273.0 discloses a kind of metallic carrier preparation method, and cellular inner core is inserted making in the stage portion that fuse shrinks a little of discerptible mould, and along with being pressed in the urceolus.Or an end of cellular inner core is inserted the internal diameter that an end swollen be substantially equal to exert pressure then fuse is pressed into urceolus in the urceolus of fuse external diameter, heat-treat swelling partially retracted at last.This technology is too complicated.
Patent CN02817320.1 discloses a kind of method and apparatus that applies scolder by means of vibration to metal structure.Promptly the cellular inner core of having spooled is placed in the shell,, applies Ni-based welding powder to cellular inner core and cellular inner core and shell joint portion by means of vibration, but the Ni-based welding powder particle of this technological requirement is very little, particle is at 20～120um, and so tiny Ni-based welding powder cost is higher, and complex process.
Patent CN03151202.X discloses the preparation method of a kind of cross section for circular metallic carrier.Some soldering bars of two sides spot welding with flat plate, corrugated plate is selected some centimeters of an end that is welded in the anomaly plate, this end is as the initiating terminal of reeling, be wound into honeycomb core, yet insertion outer sleeve, at the two ends of honeycomb ceramics honeycomb core is connected with the contact position spot welding of outer sleeve again, at last by the soldering oven soldering.But because the honeycomb inner core and the internal diameter of outer cover of metallic carrier are almost equal, the honeycomb inner core being packed in the process of shell easily makes cored solder be pushed out, there have how many scolders to stay between honeycomb inner core and the shell on earth to be uncontrollable, although so adopted spot-welding technology, the soldering strength of honeycomb inner core and shell still is difficult to guarantee.
Summary of the invention
Purpose of the present invention just provides a kind of manufacture method that can improve the metallic carrier of soldering strength between cellular inner core and the shell, the welding cost that prior art exists is higher to solve, the honeycomb inner core packed in the process of shell in complex process and the spot-welding technology cored solder is pushed out, the uncontrollable problem of staying the amount of solder between honeycomb inner core and the shell.
The present invention can reach by following technical solution: described metallic carrier has a kind of cellular inner core that contains many passages that extend along axis direction and cylindrical shape that is coated on this cellular inner core periphery or non-cylindrical shell and it is characterized in that: at described cylindrical shape or non-cylindrical outer casing inner wall along the Ni-based shaped brazing material of its circumferencial direction roll welding, then cellular inner core is inserted in the shell, at last by the soldering oven soldering.
Described Ni-based shaped brazing material can according to one of the height roll welding of metallic carrier for catalyst, two or more.
Owing to adopt technique scheme, with the roll welding of banded nickel-based brazing material at the local inwall of metallic carrier shell, the close applying pressure welding of banded nickel-based brazing material meeting is at the metallic carrier outer casing inner wall under roll extrusion, substantially there is not the dimpling protuberance, can not produce the phenomenon that outer casing inner wall solder band is pushed out even the cellular inner core external diameter of metallic carrier is equal to the metallic carrier internal diameter of outer cover yet, guarantee the weld strength between shell and the inner core.Simplify technology, reduced manufacturing cost.
Below in conjunction with drawings and Examples technology of the present invention is further specified.
Description of drawings
Fig. 1 is the perspective view of cylindrical shape and non-cylindrical metallic carrier for catalyst.
Fig. 2 is a generalized section behind the banded nickel-based brazing material of metallic carrier cylindrical shape of the present invention and the roll welding of non-cylindrical outer casing inner wall.
Fig. 3 is the schematic diagram of the banded nickel-based brazing material of manufacture method seam welder roll welding of the present invention.
Description of reference numerals: 1 metallic carrier for catalyst; 2 passages; 3 cellular inner cores; 4 shells; 5 banded nickel-based brazing materials; 6 seam welder rollers.
The specific embodiment
Referring to Fig. 1～Fig. 3, at first banded nickel-based brazing material 5 is fixed on the position of required roll welding, with seam welder (claiming seam welder again) roller 6 the pressure welding along the circumferential direction of banded nickel-based brazing material 5 on the inwall of shell 4.Position, quantity, the width of the 5 required roll weldings of banded nickel-based brazing material are decided according to position, quantity and width that the expectation soldering connects.On the inwall at end 0.5～50mm place, banded nickel-based brazing material 5 thickness are generally 0.01～0.1mm to the 5 general roll weldings of banded nickel-based brazing material at shell 4, and width is generally 1.5～30mm, and the bar number is generally 1～5.
Then the cellular inner core 3 of coiling and molding is inserted in the shell 4, inserts soldering oven at last and carry out soldering.
