Yuav Ua Li Cas Ntsuam Xyuas Kev Tiv Thaiv Corrosion ntawm Cov Yeeb Nkab Khoov thiab Cov Yam Ntxim Saib Ntxim Ua ntawm Cov Khoom Siv rau Induction Yeeb Nkab Khoov
Muab hais tias cov yeeb nkab khoov feem ntau tuaj rau hauv kev sib cuag nrog ib puag ncig sib txawv, nws nyuaj kom tsis txhob muaj kev cuam tshuam ntawm ib puag ncig thaum siv lawv. Txhawm rau tiv thaiv cov yeeb nkab corrosion, kev txhim kho corrosion kuj ntawm cov kav dej yog qhov tseem ceeb heev. Yog li, koj tuaj yeem kuaj qhov corrosion ntawm cov yeeb nkab dabtsi yog khoov?
1. Sib Nqus Flux Leakage Testing: Txoj kev no yog ua raws li qhov siab sib nqus permeability ntawm cov ntaub ntawv ferromagnetic. Nyob rau hauv cov cheeb tsam nrog corrosion tsis xws luag, lub magnetic permeability yog ho qis dua li ntawm cov khoom nyob ib puag ncig. Thaum raug rau sab nraud magnetic teb, qhov chaw corroded ua magnetized. Thaum tsis muaj qhov tsis xws luag, cov kab hlau nplaum feem ntau dhau los ntawm cov yeeb nkab steel, uas ua rau muaj qhov sib nqus sib nqus sib nqus. Nrog rau sab hauv tsis xws luag, cov kab hlau nplaum sib nqus khoov, thiab qee qhov kev khiav tawm ntawm cov yeeb nkab nto. Los ntawm kev kuaj pom cov hlau nplaum xau ntawm qhov chaw hlau nplaum, koj tuaj yeem txiav txim siab qhov muaj qhov tsis xws luag.
2. Ultrasonic Testing: Thaum lub sij hawm soj ntsuam ntawm cov yeeb nkab khoov, ultrasound pulses raug xa mus rau perpendicularly rau hauv lub puab phab ntsa ntawm qhov khoov. Lub ultrasonic sojntsuam pib tau txais kev xav ntawm pulses los ntawm sab hauv ntawm cov yeeb nkab phab ntsa, ua raws li tau txais kev xav ntawm sab nrauv ntawm cov yeeb nkab phab ntsa. Qhov kev ncua deb ntawm cov kev xav no qhia txog qhov tuab ntawm cov yeeb nkab phab ntsa. Hauv kev sim tiag tiag ntawm cov yeeb nkab khoov, kev tshuaj xyuas yuav tsum tau ua raws li cov kev ua tau zoo thiab cov lus qhia, ua raws li cov txheej txheem ultrasonic precisely.
Los ntawm kev siv cov txheej txheem no, koj tuaj yeem ntsuas qhov corrosion kuj ntawm cov yeeb nkab khoov. Ua raws li qhov yuav tsum tau muaj kev tiv thaiv corrosion kom ntseeg tau tias cov kav dej tuaj yeem siv tau zoo nyob rau hauv ib puag ncig hnyav, qhia txog lawv cov kev ua tau zoo.
Cov yam ntxwv ntawm cov khoom siv rau induction yeeb nkab khoov:
Qhov zoo ntawm cov yeeb nkab induction khoov tsis yog nyob ntawm cov txheej txheem tsim khoom nkaus xwb tab sis kuj nyob ntawm cov khoom siv. Cov yam ntxwv ntawm cov khoom ua si lub luag haujlwm tseem ceeb. Nov yog qee qhov tseem ceeb ntawm cov khoom siv rau induction yeeb nkab khoov:
1. Corrosion Resistance: Induction yeeb nkab khoov tau zoo heev corrosion kuj, feem ntau txiav txim los ntawm cov alloying ntsiab nyob rau hauv cov hlau. Cov ntaub ntawv siv rau hauv cov yeeb nkab induction khoov tuaj yeem tiv thaiv tsis muaj zog corrosive media xws li huab cua, chav, dej, nrog rau cov tshuaj lom neeg muaj zog xws li acids, alkalis, thiab ntsev. Cov ntaub ntawv no feem ntau hu ua stainless hlau los yog acid-resistant steels.
2. Chromium Cov ntsiab lus: Chromium yog lub hauv paus ntsiab lus uas cuam tshuam corrosion tsis kam rau induction yeeb nkab khoov. Thaum cov ntsiab lus chromium nyob rau hauv cov hlau ncav cuag ib ncig ntawm 1.2%, nws reacts nrog oxygen nyob rau hauv corrosive media, tsim ib tug tiv thaiv oxide txheej ntawm cov hlau nto. Cov oxide txheej no tiv thaiv corrosion ntxiv ntawm cov hlau substrate.
3. Distinguishing Stainless thiab Acid-Resistant Steels: Nyob rau hauv cov ntaub ntawv siv, steel resistant rau qaug zog corrosive xov xwm feem ntau hu ua stainless hlau, whereas steel resistant rau tshuaj lom neeg yog hu ua acid-resistant steel. Qhov txawv yog nyob ntawm qhov sib txawv ntawm cov tshuaj muaj pes tsawg leeg. Stainless hlau yuav tsis tiv thaiv corrosion los ntawm qee yam tshuaj lom neeg tawm tsam, thaum acid-resistant steel feem ntau tsis corrode los yog xeb.
Kev xaiv cov khoom siv yog ib qho tseem ceeb ntawm cov yeeb nkab induction khoov thiab ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa thiab txhawb kev loj hlob ntawm high-tech industries. Cov ntaub ntawv siv hauv cov yeeb nkab khoov yog qhov tseem ceeb hauv kev tshawb fawb cov ntaub ntawv tshiab, nrog cov ntaub ntawv hnav-tiv taus suav txog kwv yees li 85% ntawm cov ntawv thov no.
Cov yam ntxwv ntawm induction yeeb nkab khoov cov ntaub ntawv tau pom dav siv hauv kev lag luam xws li kev tsim hluav taws xob, roj av, tshuaj lom neeg, maritime, nuclear industries, thiab lwm yam.
