Muaj roj nyob rau hauv cov kav dej huv stainless hlau tom qab lawv ua tiav, thiab lawv yuav tsum tau ua tiav thiab ziab ua ntej cov txheej txheem tom ntej tuaj yeem ua tiav.
1. Ib qho yog nchuav cov tshuaj ntxuav roj ncaj qha rau hauv pas dej, tom qab ntawd ntxiv dej thiab muab tso rau hauv. Tom qab 12 teev, koj tuaj yeem ntxuav nws ncaj qha.
2. Lwm txoj kev ntxuav yog muab cov yeeb nkab stainless hlau tso rau hauv roj diesel, muab nws tsau rau 6 teev, tom qab ntawd muab tso rau hauv pas dej ua ke nrog cov tshuaj ntxuav, muab nws tsau rau 6 teev, thiab tom qab ntawd ntxuav nws.
Cov txheej txheem thib ob muaj qhov zoo pom tseeb. Nws huv dua los ntxuav cov kav dej huv stainless hlau.
Yog tias kev tshem tawm roj tsis huv heev, nws yuav muaj qhov cuam tshuam loj heev rau cov txheej txheem polishing tom ntej thiab cov txheej txheem nqus tsev annealing. Yog tias kev tshem tawm roj tsis huv, ua ntej tshaj plaws, kev polishing yuav nyuaj rau ntxuav thiab kev polishing yuav tsis ci.
Qhov thib ob, tom qab qhov ci ntsa iab ploj mus, cov khoom yuav yooj yim tev tawm, uas tsis tuaj yeem lav qhov khoom zoo.
Kev ncaj ntawm cov yeeb nkab stainless hlau yuav tsum tau ncaj
Ci ntsa iab, qhov sab hauv du:
Cov yeeb nkab ua tiav-dov huv stainless hlau sab hauv thiab sab nraud qhov roughness Ra≤0.8μm
Qhov roughness ntawm sab hauv thiab sab nraud ntawm lub raj polished tuaj yeem ncav cuag Ra≤0.4μm (xws li daim iav nto)
Feem ntau hais lus, cov khoom siv tseem ceeb rau kev txhuam cov kav dej stainless hlau huv yog lub taub hau txhuam, vim tias qhov roughness ntawm lub taub hau txhuam txiav txim siab qhov kev txiav txim ntawm kev txhuam ntxhib.
BA:Kev Ci Ntxuam Ci. Thaum lub sijhawm kos duab ntawm cov yeeb nkab hlau, nws yuav tsum tau siv roj nplua nyeem, thiab cov noob kuj yuav raug deformed vim yog kev ua tiav. Yuav kom tiv thaiv cov roj no kom tsis txhob nyob hauv cov yeeb nkab hlau, ntxiv rau kev ntxuav cov yeeb nkab hlau, koj tuaj yeem siv cov roj argon ua huab cua hauv lub cub tawg thaum lub sijhawm kub siab annealing kom tshem tawm deformation, thiab ntxiv ntxuav cov yeeb nkab hlau los ntawm kev sib xyaw argon nrog cov pa roj carbon thiab oxygen ntawm qhov chaw ntawm cov yeeb nkab hlau kom hlawv. Qhov chaw tsim cov nyhuv ci, yog li txoj kev no ntawm kev siv cov argon ntshiab annealing kom sov thiab sai sai txias qhov chaw ci hu ua glow annealing. Txawm hais tias siv txoj kev no los ua kom qhov chaw ci tuaj yeem ua kom cov yeeb nkab hlau huv si, tsis muaj kev sib kis sab nraud. Txawm li cas los xij, qhov ci ntawm qhov chaw no yuav zoo li qhov chaw matte yog tias piv nrog lwm txoj kev polishing (mechanical, chemical, electrolytic). Tau kawg, qhov cuam tshuam kuj cuam tshuam nrog cov ntsiab lus ntawm argon thiab tus lej ntawm lub sijhawm ntawm kev cua sov.
EP:Kev siv tshuab electrolytic polishing (Electro Polishing), electrolytic polishing yog kev siv anode kho, siv lub hauv paus ntsiab lus ntawm electrochemistry los kho qhov voltage, tam sim no, acid composition, thiab polishing lub sijhawm, tsis yog tsuas yog ua rau qhov chaw ci thiab du, qhov kev ntxuav tu kuj tseem tuaj yeem txhim kho qhov corrosion tsis kam ntawm qhov chaw, yog li nws yog txoj hauv kev zoo tshaj plaws los ua kom qhov chaw ci. Tau kawg, nws tus nqi thiab thev naus laus zis kuj nce ntxiv. Txawm li cas los xij, vim tias electrolytic polishing yuav qhia txog lub xeev qub ntawm cov yeeb nkab hlau, yog tias muaj qhov khawb loj, qhov, slag inclusions, precipitates, thiab lwm yam ntawm cov yeeb nkab hlau, nws yuav ua rau electrolysis tsis ua haujlwm. Qhov sib txawv ntawm tshuaj polishing yog tias txawm hais tias nws kuj tau ua nyob rau hauv ib puag ncig acidic, tsis yog tsuas yog yuav tsis muaj ciam teb xeb ntawm qhov chaw ntawm cov yeeb nkab hlau, tab sis qhov tuab ntawm chromium oxide zaj duab xis ntawm qhov chaw kuj tuaj yeem tswj tau kom ua tiav qhov zoo tshaj plaws corrosion tsis kam ntawm cov yeeb nkab hlau.
