Dab tsi yog Electropolished (EP) Stainless Steel Seamless Tube
Kev siv hluav taws xobyog ib qho txheej txheem electrochemical uas tshem tawm ib txheej nyias nyias ntawm cov khoom los ntawm qhov chaw ntawm lub raj hlau tsis xeb. LubEP Stainless Hlau Seamless Rajraug muab tso rau hauv cov kua electrolytic, thiab cov hluav taws xob raug hla dhau nws. Qhov no ua rau qhov chaw du thiab zoo nkauj dua, tshem tawm cov qhov me me uas tsis zoo, cov kab nrib pleb, thiab cov pa phem. Cov txheej txheem no pab txhim kho qhov chaw tiav ntawm lub raj los ntawm kev ua kom nws ci dua thiab du dua li kev txhuam hniav ib txwm muaj.
Cov Txheej Txheem Ua Haujlwm ntawm EP Stainless Seamless Steel Tubes yog dab tsi?
Cov txheej txheem tsim khoom rauEP Cov Rajmuaj ntau theem, uas zoo ib yam li kev tsim cov kav hlau tsis muaj hlau tsis muaj hlau, nrog rau kev ntxiv cov kauj ruam electropolishing los txhim kho qhov chaw tiav thiab kev tiv thaiv corrosion. Nov yog cov lus piav qhia txog cov kauj ruam tseem ceeb hauv kev tsim cov kav hlau tsis muaj hlau EP electropolished seamless:
1. Kev Xaiv Khoom Siv Raw
Cov hlau tsis xeb zoo (cov hlau tsis xeb khov kho) raug xaiv raws li lawv cov tshuaj lom neeg sib xyaw. Cov qib feem ntau rau cov hlau tsis xeb seamlesscov raj suav nrog 304, 316, thiab lwm yamcov hlau nplaum uas muaj kev tiv thaiv corrosion zoo heev.
Cov billets yuav tsum ua tau raws li cov qauv tshwj xeeb kom ntseeg tau tias lawv muaj cov khoom siv kho tshuab thiab tiv taus corrosion rau cov ntawv thov hauv kev lag luamzoo li tshuaj, khoom nojkev ua haujlwm, thiab cov khoom siv hluav taws xob.
2. Tho los yog Extrusion
Cov hlau tsis xeb billets raug cua sov kom kub heev ua ntej, ua rau lawv yooj yim khoov tau. Tom qab ntawd lub billet raug tho rau hauv nruab nrab siv lub tshuab tsoo kom ua ib lub raj khoob.
Ib lub mandrel (ib tug pas nrig ntev) raug thawb mus rau hauv nruab nrab ntawm lub billet, tsim ib lub qhov pib, tsim qhov pib ntawm lub raj seamless.
Kev rho tawm: Lub billet hollow raug thawb los ntawm lub pwm nyob rau hauv lub siab siab, ua rau lub raj seamless nrog qhov loj me xav tau.
3. Kev mus ncig tebchaws
Tom qab tho qhov, lub raj txuas ntxiv mus thiab zoo li los ntawm kev rho tawm lossis kev tsav tsheb:
Kev Pilgering: Ib tug series ntawm dies thiab rollers yog siv los maj mam txo lub raj txoj kab uas hla thiab phab ntsa thickness, thaum tseem ntev nws. Cov txheej txheem no ua rau lub raj qhov tseeb ntawmtxoj kab uas hla, phab ntsa tuab, thiab qhov tiav ntawm qhov chaw.
4. Kev Kos Duab Txias
Tom qab ntawd lub raj xa dej raug dhau los ntawm cov txheej txheem kos duab txias, uas cuam tshuam nrog rub lub raj los ntawm lub pwm kom txo nws txoj kab uas hla thiab phab ntsa tuab thaum nce nws qhov ntev.
Cov kauj ruam no txhim kho qhov tseeb ntawm lub raj thiab qhov chaw tiav, ua rau nws du thiab sib npaug ntau dua.
5. Kev Ua Kub
Tom qab cov txheej txheem kos duab txias, lub raj raug cua sov hauv lub cub tawg uas tswj tau huab cua rau kev annealing, uas txo cov kev ntxhov siab sab hauv, ua rau cov khoom mos, thiab txhim kho kev ductility.
Lub raj feem ntau raug annealed nyob rau hauv ib qho oxygen-free (inert gas lossis hydrogen) huab cua kom tsis txhob oxidation. Qhov no yog qhov tseem ceeb vim tias oxidation tuaj yeem ua rau lub raj zoo li cas thiab nws qhov corrosion puas tsuaj.kev tiv thaiv.
6. Kev siv hluav taws xob (EP)
Cov kauj ruam txhais ntawm electropolishing yog ua tiav ntawm theem no, feem ntau tom qab pickling thiab annealing, los txhim kho lub raj nto.
Electropolishing yog ib qho txheej txheem electrochemical uas lub raj raug muab tso rau hauv lub dab dej electrolyte (feem ntau yog qhov sib xyaw ntawm phosphoric acid thiab sulfuric acid). Ib qho tam sim no raug dhau los ntawmcov tshuaj, ua rau cov khoom yaj ntawm qhov chaw ntawm lub raj hauv txoj kev tswj hwm.
Yuav Ua Li Cas Electropolishing Ua Haujlwm
Thaum lub sijhawm ua haujlwm, lub raj txuas nrog lub anode (positive electrode) thiab lub electrolyte txuas nrog lub cathode (negative electrode). Thaum tam sim no ntws, nws yaj cov microscopic peaks ntawm qhov chaw ntawm lub raj, ua rau du, ci ntsa iab, thiab zoo li daim iav tiav.
Cov txheej txheem no ua kom zoo tshem tawm ib txheej nyias nyias ntawm qhov chaw, tshem tawm cov qhov tsis zoo, burrs, thiab txhua qhov oxides ntawm qhov chaw thaum txhim kho kev tiv thaiv corrosion.
