Bright annealing tov muab los ntawm H angao thev naus laus zis ua rau ci ntsa iab anneal ed raj nrog du sab hauv thiab sab nraud nto, precision dimensional kam rau ua, siab zog, muaj zog corrosion kuj thiab lwm yam.Yuav ua li cas thiaj ua tau lub raj zoo li no?
Austenitic stainless hlau yog dav siv nyob rau hauv ntau yam kev siv pej xeem, kev lag luam thiab tub rog.Lawv muaj nyob rau hauv ntau hom khoom, xws li tuav, rods, ntawv, ntawv, strips, ntawv ci, tubing, tubing, fittings, flanges thiab lwm yam forgings.
Yog tias cov hlau tsis muaj cua sov raug kho rau hauv qhov cub zoo tib yam, cov chromium tivthaiv hauv austenitic stainless hlau yuav hnov mob nrog oxygen nyob rau hauv cov huab cua los ua ib tug grey oxide txheej, hu ua 'scale', uas yuav tsum tau muab tshem tawm los ntawm pickling txheej txheem.
Lub ci ci annealing tov tuaj yeem ua kom zoo rau cov txheej txheem no.Txhawm rau kom muaj lub ntsej muag zoo, khaws cia cov xim hlau qub thiab tsis txhob xaiv, austenitic stainless hlau yuav tsum tau ci ntsa iab annealed hauv kev tiv thaiv lossis lub tshuab nqus tsev kom tsis txhob muaj xim tsis zoo.Txhua qib ntawm austenitic stainless hlau tuaj yeem raug muab tshem tawm.Cov huab cua tiv thaiv tuaj yeem yog hydrogen ntshiab, sib cais ammonia, lossis qee zaum nqus.Cov roj tiv thaiv tiv thaiv nto oxidation ntawm austenitic stainless hlau cov khoom thaum lub sij hawm annealing.
Yog li ci annealing tov muaj cov hauv qab no zoo:
1, ci annealing tsis tsuas yog txo cov yeeb nkab steel hardness, txhim kho ductility, txhim kho plasticity, tab sis kuj yooj yim txiav thiab txias deformation.
2, txhim kho corrosion kuj los ntawm kev tshem tawm intergranular carbide nag lossis daus, kom lub ntsej muag zoo nkauj.Refining grain thiab uniform steel qauv thiab muaj pes tsawg leeg, txhim kho steel zog, tab sis kuj npaj rau kev kho cua sov.
3, tshem tawm cov seem sab hauv kev ntxhov siab hauv cov hlau, tiv thaiv deformation thiab tawg.
4. Oxidation thiab decarbonization tshwm sim thaum lub sij hawm cua sov thiab cua txias nyob rau hauv ib qho yooj yim annealing, yog li cov cua kub-kho steel tau ua tiav lawm, uas ua rau kom poob thiab nqi ntawm hlau.
5. tsis tau oxidation ci, zoo corrosion kuj nto.Vim hais tias ci annealing yog kev kho cua sov ntawm sawb hlau nyob rau hauv qhov chaw tiv thaiv ntawm hydrogen thiab nitrogen gas sib tov, qhov chaw uas tsis muaj oxidation yog tau los ntawm nruj tswj cov roj tiv thaiv nyob rau hauv lub cub tawg.Piv nrog rau qhov saum npoo tau los ntawm kev sib tsoo zoo tib yam thiab pickling, vim tias tsis muaj cov txheej txheem oxidation, chromium deficiency tshwm sim raug txo rau saum npoo, thiab nws cov corrosion kuj zoo dua tom qab polishing.
6. ci kev kho mob kom tswj tau qhov ua tiav ntawm qhov dov nto, tsis tuaj yeem ua tiav thiab tau txais qhov ci ntsa iab.Vim lub ci ci annealing, qhov saum npoo ntawm lub raj khaws cov thawj hlau luster, tau txais qhov ci ntsa iab, raws li qhov yuav tsum tau ua, tuaj yeem siv ncaj qha yam tsis ua nws qhov chaw.
7.Tsis muaj teeb meem ua paug los ntawm txoj kev pickling zoo tib yam.Annealed raj tsis tas yuav tsum tau pickling los yog kev kho mob zoo sib xws, tsis txhob siv cov kua qaub, tsis muaj teeb meem ua paug los ntawm pickling.
Yog li cas peb mus txog ntawd?
On-Line Fixing & Fusing (Anealing) cov cuab yeej tuaj yeem ua kom sov lub stainless hlau welded pipeto 1050 ° C ces txias nws mus rau qhov kub thiab txias qis dua 100 ° C nyob rau hauv kev tiv thaiv ntawm hydrogen.Qhov cua sov fais fab mov ntawm intermediate ferquency induction yog DSP newest + IGBT qauv.Nrog DSP cov kev tswj hwm digital, muaj kev tiv thaiv tus kheej thiab kev kuaj xyuas tus kheej ua haujlwm.Nrog me me, nws heats cov kav dej sai thiab ua tau zoo nrog lub zog-txuag thiab cov khoom pov tseg tsawg.Qhov tshwj xeeb tsim inducer tsim raws li cov yam ntxwv ntawm stainless steel tuaj yeem txuag tau 15% -20% lub zog sib piv ntawm lwm cov khoom ntawm tib chav kawm.Siv hydrongen li roj txhua feeb.
