Stainless hlau tube ntau lawm txheej txheem

Txias Rolling:nws yog kev ua haujlwm siab thiab ncab ductility. Smelting tuaj yeem hloov cov tshuaj muaj pes tsawg leeg ntawm cov ntaub ntawv hlau. Txias dov tsis tuaj yeem hloov cov tshuaj muaj pes tsawg leeg ntawm cov hlau, lub kauj yuav muab tso rau hauv cov khoom siv txias dov yob siv cov kev sib txawv, cov kauj yuav txias dov mus rau qhov sib txawv thicknesses, thiab tom qab ntawd dhau los ntawm qhov kawg yob, tswj cov coil thickness raug, qhov tseeb dav hauv 3 txhob lo lo ntxhuav.

 

Annealing:Lub tshuab txias txias yog muab tso rau hauv lub tshuab hluav taws xob kev tshaj lij, ua kom sov rau qee qhov kub (900-1100 degrees), thiab qhov ceev ntawm lub qhov cub annealing tau hloov kho kom tau qhov tsim nyog hardness. Cov khoom yuav tsum yog mos, lub annealing ceev yog qeeb, qhov siab dua tus nqi sib xws. 201 thiab 304 yog austeniticstainless hlau, nyob rau hauv cov txheej txheem annealing, qhov xav tau kub thiab txias los kho lub koom haum metallurgical ntawm cov txheej txheem txias dov raug puas tsuaj, yog li cov annealing yog qhov tseem ceeb heev. Qee lub sij hawm annealing tsis zoo txaus los tsim xeb yooj yim.

 

Lub workpiece yog rhuab mus rau ib tug predetermined kub, tuav rau ib tug tej lub sij hawm ntawm lub sij hawm thiab ces maj mam txias hlau cua sov txheej txheem. Lub hom phiaj ntawm annealing yog:

1 txhawm rau txhim kho lossis tshem tawm cov hlau hauv casting, forging, dov thiab vuam txheej txheem tshwm sim los ntawm ntau yam kev ua haujlwm tsis xws luag thiab kev ntxhov siab, los tiv thaiv lub workpiece deformation, tawg.

2 soften lub workpiece rau txiav.

3 ua kom zoo dua cov nplej, txhim kho lub koom haum los txhim kho cov khoom ntawm cov khoom ua haujlwm. Lub koom haum npaj rau kev kho cua sov zaum kawg thiab kev ua yeeb nkab.

 

Slitting:stainless hlau kauj, txiav rau hauv qhov sib thooj dav, thiaj li ua tiav kev sib sib zog nqus thiab cov yeeb nkab ua, cov txheej txheem slitting yuav tsum tau them sai sai rau kev tiv thaiv, kom tsis txhob khawb lub kauj, slitting dav thiab yuam kev, ntxiv rau slitting kev sib raug zoo ntawm cov yeeb nkab ua cov txheej txheem, slitting ntawm steel sawb tshwm nyob rau hauv lub batch ntawm fronts thiab burrs, chipping ncaj qha cuam tshuam cov yield ntawm welded yeeb nkab.

 

Vuam:Cov txheej txheem tseem ceeb tshaj plaws ntawm stainless hlau raj, stainless hlau yog tsuas yog siv argon arc vuam, siab zaus vuam, plasma vuam, laser vuam. Tam sim no feem ntau siv yog argon arc vuam.

Argon arc vuam:shielding roj yog cov ntshiab argon los yog cov roj sib xyaw, cov vuam zoo, kev ua haujlwm zoo vuam, nws cov khoom siv hauv kev lag luam chemical, nuclear thiab zaub mov tau dav siv.

High-frequency vuam:nrog lub zog hluav taws xob ntau dua, rau cov ntaub ntawv sib txawv, sab nrauv phab ntsa thickness ntawm cov yeeb nkab steel tuaj yeem ua tiav qhov vuam ceev dua. Piv nrog argon arc vuam, yog nws qhov siab tshaj plaws vuam ceev ntawm ntau tshaj 10 zaug. Piv txwv li, kev tsim cov yeeb nkab hlau uas siv cov vuam vuam ntau zaus.

Plasma vuam:muaj zog nkag mus rau hauv lub zog, yog siv tshwj xeeb kev tsim kho ntawm plasma torch ua los ntawm high-temperature plasma arc, thiab nyob rau hauv kev tiv thaiv ntawm kev tiv thaiv roj fusion hlau vuam txoj kev. Piv txwv li, yog hais tias lub thickness ntawm cov khoom mus txog 6.0 hli los yog ntau tshaj, plasma vuam feem ntau yuav tsum tau los xyuas kom meej tias cov weld seam yog welded los ntawm.

Stainless hlau welded yeeb nkabnyob rau hauv lub square tube, lub duab plaub, oval tube, zoo li lub raj, pib los ntawm lub round raj, los ntawm kev tsim cov round raj nrog tib lub voj voog thiab tom qab ntawd tsim rau hauv cov raj zoo sib xws, thiab thaum kawg shaping thiab straightening nrog pwm.

Stainless hlau raj ntau lawm txheej txheem yog ntxhib, feem ntau ntawm lawv yog txiav nrog hacksaw hniav, txiav yuav tsim ib tug me me batch ntawm fronts; lwm yam yog ib tug band saw txiav, piv txwv li, loj txoj kab uas hla stainless hlau raj, kuj muaj ib tug batch ntawm fronts, feem ntau batch ntawm fronts ntau heev thaum cov neeg ua hauj lwm yuav tsum tau hloov cov saw hniav.

Polishing: Tom qab cov yeeb nkab tsim, qhov saum npoo yog polished los ntawm polishing tshuab. Feem ntau, muaj ntau yam txheej txheem rau saum npoo ntawm cov khoom siv thiab cov khoom siv kho kom zoo nkauj, polishing, uas tau muab faib ua ci (daim iav), 6K, 8K; thiab xuab zeb tau muab faib ua cov xuab zeb thiab cov xuab zeb ncaj, nrog 40 #, 60 #, 80 # 180 #, 240 #, 400 #, 600 #, kom tau raws li qhov sib txawv ntawm cov neeg siv khoom.
