Dab tsi yog Aluminium Flat Bar tiag tiag
Ib lub tiaj tiaj yog cov khoom sib dhos ntev ntev, tsis yog ib qho folded lossis hollow seem. Dav -rau-thickness ratios nyob rau hauv cov khoom lag luam khiav ntawm li 3: 1 txog 20: 1, uas yog qhov sib cais ib lub tiaj tiaj ntawm sawb lossis phaj hauv hnub- mus rau - hnub ua lag luam. Ob txoj kev tsim khoom muaj zog: ncaj qha extrusion ntawm seem los ntawm kev tuag, them los ntawm ASTM B221M rau extruded tuav, rods thiab profiles, thiab shearing los yog slitting ntawm dov phaj, them los ntawm ASTM B209M rau daim ntawv thiab phaj. Extruded bar ib txwm ua rau kub hnyiab O, T4, T6, T6510 thiab T6511; lub phaj phaj bar nqa H- kub xws li H14, H32 lossis H112.
Qhov sib txawv tseem ceeb ntawm kev yuav khoom. Extruded bar muaj lub kaum sab xis ntawm lub vojvoog, kev tswj kom nruj dua thiab kev tuag- tshwj xeeb zeb tiav. Slit phaj bar muaj dov npoo thiab ib qho chaw tau txais los ntawm niam txiv phaj. Kev qhia ib daim ntawv thaum daim duab xav tias lwm qhov yog ib qho ua rau haum- teeb meem ntawm qhov chaw.
Yam tsawg kawg nkaus los ntawm Alloy thiab Temper
Kev xaiv pib nrog lub zog-rau- qhov hnyav txiav txim siab. Cov duab hauv qab no tau teev tseg minima rau cov ntaub ntawv cov khoom lag luam, tsis yog cov txiaj ntsig kev xeem.
| Alloy / kub | Yam khoom | Tensile Rm | Yield Rp0.2 | Hom kev siv |
|---|---|---|---|---|
| 6061-T6 | Extruded bar, ASTM B221M | Min 262 MPa (38 ksi) | Min 241 MPa (35 ksi) | Tshuab puag, brackets, busbar |
| 6082-T6 | Extruded bar, EN 755-2 | Min 295 MPa | Min 250 MPa | Structural framing, cleats |
| 6063-T5 | Extruded bar, ASTM B221M | Min 186 MPa (27 ksi) | Min 145 MPa (21 ksi) | Trim, framing, fittings |
| 5052-H32 | Phaj lossis slit bar, ASTM B209M | 228-281 MPa (33-41 ksi) | Min 193 MPa (28 ksi) | Marine trim, tank strapping |
| 5083-H116 | Phaj, ASTM B928M | Min 303 MPa (44 ksi) | tswj los ntawm ASTM B928M | Hulls, thauj cov qauv |
Thaum tshav kub kub- kho tau qib 6xxx tau txais lub zog los ntawm kev kho cov tshuaj thiab kev laus, yog li lub siab npau taws, tsis yog tus ntoo khaub lig- ntu, teeb tsa kev ua haujlwm. Tsis yog-kub- kho tau qib 5xxx thiab 3xxx tau txais lub zog tsuas yog los ntawm kev ua kom tawv nqaij: ib qho 5052-H32 bar tsis tuaj yeem nce mus rau 6061-T6 lub zog los ntawm kev kho cua sov, thiab cua sov H-temper bar siab tshaj li ntawm 150℃rau lub sijhawm ntev nws yuav txo tau.
Qhov twg Flat Bars Specification
Architectural thiab structural framing: qhov rais thiab qhov rooj sub-frames, glazing txhawb, ru tsev thiab cladding brackets, tes ncej thiab balustrade rails, qhov twg 6063-T5 los yog 6061-T6 predominates.
Machinery thiab cog: puag daim hlau, tshuab tiv thaiv, conveyor sab rails, spacers thiab jig Cheebtsam. Extruded 6061-T6 cov cav tov huv si thiab tuav tapping threads zoo, uas yog vim li cas nws dominates fixture ua hauj lwm.
Hluav taws xob: busbar thiab vaj huam sib luag ua haujlwm. Kev siv hluav taws xob yog li 55% IACS rau 6101-T6 thiab txog 43% IACS rau 6061-T6, tawm tsam li 61% IACS rau EC-qib 1350, yog li kev xaiv qib cuam tshuam ncaj qha rau lub peev xwm nqa tam sim no thiab kub nce.
Kev thauj mus los thiab kho: railings, kick plates, deck trim, roj teeb -box framing and fields repairs where a bolted or welded flat section replaces a damage.
Yuav Qhia Li Cas Rau Kev Muag Khoom
Cov kab ua tiav muaj rau qhov tseeb: alloy thiab temper, hla -section (dav los ntawm thickness), ntev los yog random-ntev ntau, kam rau ua chav kawm, ntug thiab kaum sab xis, thiab nto tiav. Ntxiv cov ntaub ntawv tshuaj ntsuam yuav tsum tau. Rau cov qauv lossis siab- ua haujlwm nyob ib sab ib daim ntawv pov thawj EN 10204 3.1 nrog cua sov-tus lej traceability yog qhov kev cia siab ib txwm. Qhov twg tau teev tseg anodic tiav, hais cov chav kawm txheej: 18 micrometers (Class I) lossis 10 micrometers (Class II) raws li AAMA 611.
Fabrication and Handling Notes
6061-T6 yog feem ntau machinable bar alloy tab sis qhov tsawg tshaj plaws zam txim nyob rau hauv dabtsi yog khoov. Kev tsim nws kom nruj radii feem ntau hu rau qhov nruab nrab anneal lossis hloov mus rau 5052-H32, uas ua rau pom tseeb me me khoov radii ntawm tib lub thickness. Sawing extruded bar rau ntawm qhov pom txias nrog qhov tsis zoo -rake carbide hniav ua rau lub npoo tsis muaj burr; phaj-slitted bar yuav tsum tau deburred ntawm ob sab ua ntej anodizing, vim hais tias dov npoo tuaj yeem ntxiab lubricant residue uas zoo li staining ib zaug anodic zaj duab xis kaw.
Anodizing converts nto aluminium rau hauv oxide, yog li machined threads hlob me ntsis tom qab txheej. Qhov twg ib feem coated yuav tsum sib sau ua ke rau cov txiv ntseej coated, qhia cov nyiaj pub dawb los yog npog cov xov. Extruded bar yog feem ntau nkag rau hauv 3 m mus rau 6 m mill lengths nrog txiav - mus rau - ntev kev pab cuam, thiab cov ntu ntev yuav tsum muab cia rau hauv cov ntoo, tsis slung, los tiv thaiv ncaj.
Corrosion cwj pwm yog tsim nyog rau kev kuaj zaum kawg. Flat bar siv sab nraum zoov hauv cov huab cua ntawm ntug dej hiav txwv ua tau zoo nyob rau hauv 5052 thiab 5083, thiab txaus nyob rau hauv 6061 thaum lub nto yog anodized los yog coated. Qhov twg bar tiv tauj hlau los yog stainless fasteners, cais cov sib koom tes nrog ib tug barrier washer los yog coated fastener los tiv thaiv galvanic nres tsav los ntawm qhov sib txawv ntawm cov hlau.
Cov lus nug nquag
Q:Qhov twg aluminium tiaj tiaj bar alloy haum rau dav dav - lub hom phiaj kev sib txuas?
A: 6061-T6 extruded bar. Nws muaj qhov tshwj xeeb tshaj tawm lub zog ntawm 241 MPa (35 ksi) nyob rau hauv ASTM B221M, cov cav tov thiab welds tsim nyog, thiab muaj nyob rau hauv qhov dav ntawm qhov dav thiab thicknesses.
Q:Puas yog aluminium tiaj tus bar tuaj yeem welded rau ntawm qhov chaw?
A: Yog. 5083 thiab 5052 tuav tau yooj yim; 6061-T6 xav tau 4043 lossis 5356 muab tub lim thiab yuav plam lub zog hauv tshav kub- thaj chaw cuam tshuam, yog li cov pob qij txha yuav tsum tau tsim rau ntawm ncej-weld zog es tsis yog cov ntaub ntawv niam txiv-hlau.
Q:Dab tsi yog qhov txawv ntawm extruded bar thiab slit phaj bar?
A: Extruded bar yog nias los ntawm qhov tuag thiab tau txhais lub kaum radii ntxiv rau nruj dua; slit phaj bar yog sheared los ntawm dov phaj, muaj dov npoo, thiab feem ntau pheej yig dua 100 hli dav.
Q:Yuav ua li cas ncaj ncees tswj nyob rau hauv cov specification?
A: Kev ncaj yog lub zeb kam rau ua khi rau ntev thiab tuab. Nws yuav tsum tau hais los ntawm ASTM B221M rau extruded bar thiab los ntawm ASTM B209M rau phaj, es tsis yog sab laug raws li cov lus qhia dav dav ntawm daim duab.
Q:Puas yog anodizing hloov qhov ntev ntawm lub tiaj tus bar?
A: Yog. Cov zaj duab xis anodic loj hlob sab nraud thiab sab hauv los ntawm qhov chaw qub. Rau Chav Kawm I txheej txheej ntawm 18 micrometers, cia li 0.01 hli ntawm txhua qhov ntev ua ntej txheej yog qhov tseem ceeb.
Q:6063 puas tuaj yeem hloov pauv rau 6061 hauv kev thauj khoom -cov kabmob bar?
A: Tsuas yog tom qab kuaj xyuas kev ntxhov siab. 6063-T5 muaj qhov tsawg kawg nkaus tawm lub zog ntawm 145 MPa (21 ksi) tawm tsam 241 MPa (35 ksi) rau 6061-T6, yog li kev hloov pauv ncaj qha ntawm seem sib npaug feem ntau txo qhov peev xwm los ntawm ib puag ncig 40%.
