Description
The present invention relates to the metal carrier for purifying waste gas and the method for making thereof of a kind of metal carrier for purifying waste gas and method for making thereof, particularly a kind of honeycombed structure.
Carrier as purifying the catalyst that automobile exhaust uses has known metallic carrier with the made melikaria of the heat-resisting stainless steel of tool.This metallic carrier is the periphery by the honeycomb core that overlapping and coiling flat board and ripple plate are become, engage with the inner face of metal outer cylinder constitute.
The manufacture method of common metallic carrier includes:
Promptly disclosing in the Japanese Patent Publication 63=44466 communique has overlapping and reel dull and stereotyped and ripple plate, near the position of at least simultaneously side of the both ends of the surface side of the honeycomb metal core body that become of secondly will the reeling metallic carrier that in addition brazing filler metal became.Only, this kind metallic carrier, when with its reality be installed on the automobile engine time, cause the situation of thermal fatigue because of heating, the thermal cycle meeting of cooling off both, to make the honeycomb metal core body produce distortion, perhaps make the sour broken situation of breaking of giving birth to of paillon foil of honeycomb metal core body peripheral part.Particularly the waste gas at the honeycomb metal core body imports side, and because of it is exposed under the waste gas of high temperature, the disrumpent feelings situation of the distortion of honeycomb metal core body and paillon foil is to the utmost point obvious.Again, metallic carrier is owing to must bear the vibration of engine and the vibration in the walking, and its joining portion often has disrumpent feelings situation to take place.
Japanese Patent Publication 56-4373 communique discloses to be had: the container that is filled with liquid scolding tin slurry certainly, via supplying with roller, behind coating scolding tin on the summit of the steel plate of smooth steel plate or waveform, the former and Corrugated Sheet Steel, the latter and dull and stereotyped steel plate are reeled and the honeycomb metal core body that is shaped together.Again, same communique, announcement has: before coating scolding tin, on the position of preparing coating scolding tin, via supplier, behind elder generation's coating solid, by dispensing device, Yi Bian scatter the powdered solder, Yi Bian and reel and the honeycomb metal core body of shaping.These honeycomb metal core bodys are to be the solder particle with powdered, and lamination is a multilayer between dull and stereotyped steel plate and Corrugated Sheet Steel.Again, the lamination portion of the powdered solder particle between dull and stereotyped steel plate and Corrugated Sheet Steel, when implementing the vacuum brazing processing for the twice that between the most peripheral of honeycomb metal core body, is winding number at honeycomb metal core body center, the Yi Fashengyin solder dissolves and makes and produces the gap between dull and stereotyped steel plate and Corrugated Sheet Steel, and this gap is that the multilayer area combines on several positions.Therefore, the honeycomb metal core body of method gained between dull and stereotyped steel plate and Corrugated Sheet Steel, has not by the part of brazing filler metal by this.Because of the solder thickness at the joining portion of dull and stereotyped steel plate and Corrugated Sheet Steel is extremely thick,, and make its intensity comparatively not fill part so in the solder portion of fragility, easily take place disrumpent feelingsly again.
Secondly, in metal outer cylinder, insert the honeycomb metal core body, and on the honeycomb metal core body, support waste-gas cleaning with the exhaust gas purifier of catalyst, many known kinds are just arranged from the past, particularly, may command and even prevent to be that many motions are arranged because of the peeling off and damaged all honeycombed structures of the joining portion that generation caused of the distortion that thermal stress caused that heat produced of automobile exhaust gas.For example, promptly disclosing in the Japanese kokai publication hei 4-29750 communique has by on the axle direction that is formed on metallic carrier, and is separated with ring-type a plurality of belt bodies at interval of 1-15mm, metallic honeycomb substrate and urceolus is engaged the metallic carrier that is become.It is the stress that will occur in when the cool thermal cycle on the carrier shaft direction, by the distortion that locational disengaged part produced at interval of aforementioned ring-type, absorbs it and distorts, and the stress that acts on joining portion and disengaged is disperseed.Only, even if engaged by a plurality of belt bodies between urceolus and honeycomb metal core body, the quality because of the jointing state of honeycomb metal core body also has the situation that can't effectively disperse its stress.For example, when the joint boundary between honeycomb metal core body and urceolus portion and the joint boundary in the honeycomb metal core body are consistent situation,, and make it the disrumpent feelings of paillon foil take place from this place because of the stress that thermal cycle produced will concentrate on this place.Again, disclose in the Japanese kokai publication hei 4-148016 communique a kind of metallic carrier is arranged, it is on the axle direction of flat paper tinsel and ripple paper tinsel, with between the axle direction length 5%-20% length of honeycomb metal core body every, have an engaging zones, and, in the skin of aforementioned metal honeycomb core plays to the inboard 5 layers, on axle direction, have engaged outer strengthened layer, and in the axle direction scope in aforementioned outer strengthened layer zone, metal outer cylinder is combined with the honeycomb metal core body.In this case, metal cylinder and honeycomb metal core body are engaged with the axle direction thermal distortion that an axial local event can relax metal outer cylinder and honeycomb metal core body.Only, because of its metal outer cylinder has only a place with the place that engages of its honeycomb metal core body, the vibration when being derived from the mechanicalness vibration of engine and walking will concentrate on the joining portion, so on paillon foil disrumpent feelings situation may take place.Again, Japan opens to disclose in the flat 2-83320 communique in fact a kind of exhaust gas purifier, it is that a plurality of honeycomb metal core bodys compartment of terrain that has a plurality of mesh shape vents road on axle direction that the planar band of thin meat sheet metal and state manufacturing that the tabular band of ripple is overlapped into mutual butt are come out is bonded to article in the metal shell of both ends open, and the bearing surface between the outer circumferential face of each honeycomb metal core body and metal shell internal face, except with the internal face of near outer circumferential face the two end part of honeycomb metal core body and aforementioned metal housing simultaneously in addition outside the situation of set, its at least set a place is arranged.Again, Japan opens to disclose in the flat 2-85814 communique in fact a kind of exhaust gas purifier, it is that two are become the state of mutual butt by the planar band of overlapping thin meat sheet metal and the tabular band of ripple and make the honeycomb metal core body that has most mesh shape vent roads on axle direction that become, the compartment of terrain is bonded to both ends open and has the supported exhaust gas that is become in the tubular metal outer cylinder of wide diameter portion and purifies the exhaust gas purifier of using catalyst, it is characterized in that: near the outer circumferential face on the aforementioned metal urceolus opening portion of each honeycomb metal core body is bonded on the internal face of metal outer cylinder, and near the outer circumferential face on the spacer portion of each honeycomb metal core body is not connected on the internal face of metal outer cylinder.
These waste exhaust gases purification plants, be peeling off of the internal face of the outer circumferential face of thermal stress that prevents honeycomb metal core body and metal outer cylinder and the honeycomb metal core body that thermal distortion caused and metal outer cylinder, and for preventing to constitute the flat board of honeycomb metal core body and peeling off and crack failure of ripple plate, be that a plurality of honeycomb metal core bodys compartment of terrain is bonded in the metal outer cylinder, simultaneously, on the bearing surface of the internal face of the outer circumferential face of each honeycomb metal core body and metal outer cylinder, by the some on the set axle direction only, preferably detour full week and circlewise, disperse thermal stress by this and carry out its affinity.
Only, though method can be disperseed and the affinity thermal stress by this, also can't absorb because of occurring in thermal stress on the waste exhaust gases purification plant and near the distortion honeycomb metal core body outer circumferential face that thermal distortion caused.Therefore, near honeycomb metal core body outer circumferential face, it easily affords thermal stress and thermal distortion, and the situation such as peel off on the joining portion of crystal grain distortion and dull and stereotyped and ripple plate takes place.Again, only set some between metal outer cylinder internal face and honeycomb metal core body outer circumferential face, its jointing state very a little less than, exhaust airstream pressure at high temperature will make it can't keep its set position.
