Stainless hlau los ntawm ntau qhov kev ua tiav.Nws yog ib qho tseem ceeb kom paub tias cov kev ua tiav no yog dab tsi thiab vim li cas lawv tseem ceeb.Qhov kev hloov tshiab tshiab hauv kev siv tshuab abrasive tuaj yeem txo cov txheej txheem kom xa cov kev xav tau tiav, suav nrog kev nrhiav tom qab gloss.
Stainless hlau tuaj yeem nyuaj rau kev ua haujlwm nrog, tab sis cov khoom tiav muaj ib qho zoo tshaj plaws thiab ua rau tag nrho cov kev ua haujlwm tsim nyog.Nws yog feem ntau lees txais tias siv cov grit zoo dua hauv cov xuab zeb sib lawv liag tuaj yeem tshem tawm cov qauv kos yav dhau los thiab txhim kho qhov tiav, tab sis muaj ntau ntau cov kauj ruam yuav tsum paub txog thaum siv ntau cov grit sequences kom ua tiav qhov xav tau.

Kev Lag Luam Tshwj Xeeb Steel ntawm North America (SSINA) piav qhia txog cov qauv kev lag luam thiab qhov twg cov khoom siv sib txawv cov lej tiav.
No. 1 yog ua tiav.Qhov kev kho deg no yog ua los ntawm dov (kub dov) stainless hlau uas tau ua kom sov ua ntej dov.Qhov kev ua tiav me me yuav tsum tau ua, uas yog vim li cas nws thiaj li suav hais tias yog qhov ntxhib.Cov khoom lag luam uas muaj pes tsawg leeg yog cov cua kub cua sov, lub thawv annealing, boiler baffles, ntau lub tshuab hluav taws xob, thiab roj turbines, rau npe ob peb.
No. 2B ua tiav.Qhov no ci ntsa iab-dov zoo li daim iav pos huab thiab yuav tsum tsis muaj cov kauj ruam ua tiav.Cov khoom uas muaj 2B tiav muaj xws li universal pans, cov khoom siv cog tshuaj, cutlery, ntawv zeb khoom thiab cov kav dej.
Kuj tseem muaj 2D tiav hauv qeb 2.Qhov tiav no yog ib qho zoo, matte silver grey rau nyias coils, lub thickness ntawm uas tau raug txo los ntawm ib tug txias dov tsawg kawg nkaus txheej txheem raws li nws yog feem ntau siv nrog ib tug Hoobkas tiav.Pickling los yog descaling yuav tsum tau tom qab tshav kub kev kho mob kom tshem tawm chromium.Pickling yuav ua tau kawg ntau lawm kauj ruam rau no nto kev kho mob.Thaum ib tug zoo nkauj substrate yuav tsum tau pleev xim rau 2. .
Polish No. 3 yog tus cwj pwm los ntawm luv luv, kuj tuab, cov kab sib npaug sib npaug.
Rau cov neeg kho tshuab polishing, 50 lossis 80 grit feem ntau yog siv thawj zaug, thiab 100 lossis 120 grit feem ntau yog siv rau polishing zaum kawg.Nto roughness feem ntau muaj qhov nruab nrab roughness (Ra) ntawm 40 microinches lossis tsawg dua.Yog tias cov chaw tsim khoom xav tau fusion welds lossis lwm yam trimming, cov khoom siv polishing ntau dua li cov khoom siv polishing, feem ntau yog cov khoom siv polishing. Cov khoom siv ua zaub mov, khoom siv hauv chav ua noj, thiab cov cuab yeej tshawb fawb yog qhov No.
No. 4 tag yog feem ntau thiab yog siv nyob rau hauv cov khoom siv thiab khoom noj khoom haus industries.Nws cov tsos yog characterized los ntawm luv luv parallel polished kab txuas tusyees raws qhov ntev ntawm lub coil.It yog tau los ntawm mechanically polishing tiav No. 3 nrog progressively finer abrasives.Nyob ntawm daim ntawv thov, qhov kawg tiav yuav ua tau nyob txhua qhov chaw ntawm 120 thiab 30 polishive polished.
Nto roughness feem ntau yog Ra 25 µin.lossis tsawg dua.Qhov kev ua tiav no yog siv dav hauv cov tsev noj mov thiab cov khoom siv hauv chav ua noj, khw muag khoom, kev ua zaub mov thiab cov khoom siv mis nyuj.As nrog Finish No. 3, yog tias tus neeg teb xov tooj xav tau fuse welds los yog ua lwm yam kev sib tw, cov kab polished feem ntau ntev dua li cov kab ntawm cov khoom polished los ntawm cov chaw tsim khoom lossis cov khoom siv hauv tsev kho mob. los yog tswj vaj huam sib luag, thiab cov tshuab tso dej.
Polish No. 3 yog tus cwj pwm los ntawm luv luv, kuj tuab, cov kab sib npaug sib npaug.
Finish No. 7 yog qhov muaj kev cuam tshuam zoo heev thiab muaj lub ntsej muag zoo li daim iav.Polished mus rau 320 grit thiab polished No. 7 tiav feem ntau tuaj yeem pom nyob rau hauv kem lub kaus mom, cov hniav zoo nkauj thiab phab ntsa panels.
Muaj kev txhim kho tseem ceeb hauv cov abrasives siv los ua kom tiav cov txheej txheem saum npoo av, pab cov tuam txhab tsim khoom ntau yam nyab xeeb, sai, thiab raug nqi.
Cov abrasives no muab kev txiav ceev ceev, lub neej ntev, thiab txo cov kauj ruam uas yuav tsum tau ua kom tiav.Piv txwv li, lub flap nrog microcracks hauv cov khoom siv ceramic txuas nws lub neej ntawm tus nqi qeeb thiab muab kev ua tiav zoo ib yam.
Tsis tas li ntawd, cov thev naus laus zis zoo ib yam li cov abrasives sib sau ua ke muaj cov khoom sib txuas ua ke kom txiav nrawm dua thiab ua kom tiav zoo dua.Nws yuav tsum muaj cov kauj ruam tsawg dua thiab cov khoom siv abrasive tsawg dua los ua txoj haujlwm, thiab cov neeg ua haujlwm feem ntau pom kev ua haujlwm zoo dua thiab txuag nqi.

Cov neeg tsim khoom tau sib tw ua kom tiav cov ces kaum thiab radii ntawm stainless hlau qhov chaw.To muab cov tawv tawv-mus cuag welds thiab tsim cov cheeb tsam, nws muaj tsib-kauj ruam txheej txheem uas yuav tsum tau ib tug sib tsoo log, ib tug square ncoo ntawm ob peb grits, thiab ib tug uniform sib tsoo log.
Ua ntej, cov neeg tsav tsheb siv lub log sib tsoo kom sib sib zog nqus khawb ntawm cov khoom siv stainless hlau.Grinding log feem ntau yog nruj thiab tsis tshua zam txim, muab tus neeg teb xov tooj ntawm qhov tsis zoo thaum pib.Cov kauj ruam sib tsoo yog siv sij hawm siv thiab tseem tshuav cov khawb uas yuav tsum tau muab tshem tawm los ntawm peb qhov ntxiv pad finishing cov kauj ruam ntawm cov nplej sib txawv.Cov kauj ruam no yog ua raws li kev siv lub log sib tsoo kom tiav lub siab xav.
Los ntawm kev hloov lub log sib tsoo mus rau lub log ceramic lobe, tus neeg teb xov tooj tuaj yeem ua tiav polishing hauv thawj kauj ruam.Ua kom zoo li qub grit raws li nyob rau hauv cov kauj ruam thib ob, tus neeg teb xov tooj hloov cov square pads nrog lub suab nrov nrov, txhim kho lub sijhawm thiab ua tiav.
Tshem tawm 80-grit square ncoo thiab hloov nws nrog cov tsis-woven mandrel nrog agglomerated hais raws li 220-grit non-woven mandrel tso cai rau tus neeg teb xov tooj los tsim qhov xav tau sheen thiab tag nrho cov tiav thiab tshem tawm qhov xav tau ntawm cov kauj ruam kawg yog cov txheej txheem qub (siv lub log sib koom ua ke los kaw cov kauj ruam).
Ua tsaug rau kev txhim kho ntawm lub log flapper thiab cov cuab yeej siv tsis-woven, tus lej ntawm cov kauj ruam tau raug txo los ntawm tsib mus rau plaub, uas txo lub sijhawm ua tiav los ntawm 40% thiab txuag cov nqi zog thiab cov khoom lag luam.
Muaj kev nce qib tseem ceeb hauv cov abrasives siv los ua kom tiav cov txheej txheem saum npoo, pab cov tuam txhab tsim khoom ntau yam nyab xeeb, sai, thiab raug nqi.
WELDER, yav tas los siv vuam niaj hnub no, nthuav qhia cov neeg tiag tiag uas ua cov khoom uas peb siv thiab ua haujlwm nrog txhua hnub.Cov ntawv xov xwm no tau ua haujlwm rau cov koom haum vuam hauv North America rau ntau tshaj 20 xyoo.
