Qhov zoo ntawm kev ci annealing rau stainless hlau leeg
Stainless hlau tubes yog ib qho tseem ceeb cov khoom siv dav siv hauv petrochemical, kev tsim kho, tshuaj, thiab khoom noj khoom noj khoom haus. Txhawm rau txhim kho cov kev ua tau zoo thiab kev ua haujlwm ntev ntawm cov roj hlau stainless leeg, kev sib tw ci ci tau dhau los ua cov txheej txheem kev kub ntxhov. Ci annealing tsis tsuas yog txhim kho cov tshuab ua haujlwm ntawm cov hlau hlau stainless leeg tab sis kuj txhim kho lawv cov corrosion tsis kam thiab zoo. Kab lus no yuav tham txog qhov zoo ntawm kev ci annealing rau cov hlau hlau stainless hauv kev nthuav dav.
1. Txhim kho corrosion tsis kam
Thaum lub sij hawm cov txheej txheem kub-ntsuas kub, stainless hlau leeg yog rhuab rau high kub (feem ntau ib yam nkaus li 1050 ° C) thiab tom qab ntawd txias. Qhov no tau zoo heev carbides thiab lwm cov ntsiab lus hauv stainless hlau, kom muaj kev faib tawm ntawm cov ntsiab lus tsis pub dhau ntawm cov qauv sib txawv. Cov qauv coj no tau txhim kho txoj hlab corrosion tsis kam ntawm stainless hlau leeg, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig nrog acids, alkalis, thiab ntsev.
2. Txhim kho cov khoom siv kho tshuab
Cov kws kho tshuab cov khoom siv ntawm cov hlau stainless leeg tau txhim kho tom qab ci annealing. Cov txheej txheem cua sov thiab cov txheej txheem txias nrawm kom zoo tso tawm sab hauv kev ntxhov siab thiab ua kom cov qauv grain, yog li nce cov khoom sib dhos thiab lub zog ntawm cov khoom. Tsis tas li ntawd, kev ncaim plig ci tuaj yeem tshem tawm cov haujlwm hnyav, ua cov hlau stainless yas yooj yim los ua cov txheej txheem tom ntej.
3. Nce saum npoo ci
Ci annaling yog ua nyob rau hauv cov huab cua tiv thaiv (xws li hydrogen lossis ammonia decomposition roj), uas zoo tiv thaiv oxidation thiab tswj hwm lub stainless hlau leeg lub ci ci. Qhov chaw zoo ntawm stainless hlau leeg yog qhov cuam tshuam loj dua tom qab ci annealing, uas ua rau muaj kev zoo nkauj heev thiab huv si. Qhov chaw zoo nkauj no tsis yog ua kom zoo nkauj dua kev thov kom zoo nkauj ntawm lub stainless hlau leeg tab sis kuj txo cov nqi tom tsev txuas ntxiv thiab ntxuav tu.
4. Txhim kho qhov seem ruaj khov
Los ntawm tshem tawm cov kev ntxhov siab ntawm lub taub hlau stainless, ci annealing tseem ceeb dua txhim kho qhov seem ruaj khov txhim kho qhov ruaj khov ntawm cov khoom. Qhov no yog qhov tshwj xeeb tshaj yog rau cov ntawv thov cov kev ntsuas siab ntau, xws li cov khoom siv kho mob thiab cov cuab yeej siv kho mob thiab cov khoom siv thev naus laus zis. Hauv cov teb no, txawm tias qhov kev hloov pauv me me tuaj yeem cuam tshuam rau kev ua haujlwm zoo ntawm cov khoom siv, ua kom muaj kev ruaj ntseg ruaj khov.
5. Txuas Ntxiv Lub Neej
Los ntawm kev txhim kho lub corrosion tsis kam, cov khoom siv neeg siv tshuab, thiab cov khoom lag luam saum cov stainless hlau, ci ntsa iab annealing fundsally cov khoom siv lub neej kev pabcuam. Hauv kev siv cov tswv yim, stainless hlau leeg uas tau undergone ci annaling tuaj yeem ua tau zoo dua ntawm kev saib xyuas thiab hloov, yog li txo tus nqi kho.
6. Cov kev pab ib puag ncig
Kev sib tw ci ci kuj muaj qhov zoo ib puag ncig. Cov kev xaiv pickling thiab polishing txheej tsim kom muaj cov tshuaj pov tseg cov tshuaj pov tseg thiab cov khib nyiab ci, whereas ci ntsa iab ua haujlwm yuav luag tsis muaj dej lossis khib nyiab, sib ntsib txhua yam kev xav tau ib puag ncig. Tsis tas li ntawd, antheLing ci tuaj yeem txo cov txheej txheem kev ua tiav, ntxiv cov khoom lag luam tsawg dua thiab cov khoom siv pov tseg.
Hauv kev xaus, ci anegerting rau stainless hlau leeg muaj cov khoom siv corrosion, txhim kho kev ruaj khov, nce lub neej kev pabcuam, thiab cov txiaj ntsig ib puag ncig. Nrog kev nce qib txuas ntxiv thiab kev nthuav dav ntawm cov ntawv thov, kev txhawb nqa ci yuav ua rau lub luag haujlwm tseem ceeb hauv kev tsim cov hlau stainless leeg.
Txhua zaus lub raj tais tiav yog dov, nws yuav tsum dhau ntawm kev kho cov kev daws teeb meem. TA xyuas kom meej tias kev ua tau zoo ntawm cov yeeb nkab steel ua tau raws li cov kev xav tau. thiab los muab kev lees paub rau cov txheej txheem tom qab ua lossis siv. Txoj kev kho cov txheej txheem huab cua kev kho mob ntawm ultra-ntev seamless steel yeeb tau ib txwm muaj qhov nyuaj nyob rau hauv kev lag luam.
Khoom siv ib txwm muaj hluav taws xob cov khoom hluav taws xob yog qhov loj, muaj hluav taws xob loj, muaj kev siv roj loj, yog li nws nyuaj rau kev paub meej. Tom qab xyoo ntawm kev ua haujlwm nyuaj thiab kev txhim kho kev tsim kho tshiab, kev siv cov thev naus laus zis ua haujlwm hloov tshiab thiab DSP fais fab. Kev tswj hwm kev kub kub kom ntseeg tau tias qhov ntsuas kub yog tswj tau nyob rau hauv T2C, los daws cov teeb meem kev kub ntxhov ntawm kev ntsuas kub tsis raug qhov kub. Lub rhuab steel yeeb nkab yog txias los ntawm 'cua sov canuction yog qhov sib txawv kaw qhov chaw, uas tau txo cov roj hloov roj thiab yog ib puag ncig ntau dua.
