Dab tsi yog Electropolished (EP) Stainless Hlau Seamless Tube
Electropolishingyog cov txheej txheem electrochemical uas tshem tawm cov txheej nyias ntawm cov khoom siv los ntawm qhov chaw ntawm lub raj stainless hlau. CovEP Stainless Hlau Seamless Tubeyog immersed nyob rau hauv ib qho kev daws teeb meem electrolytic, thiab ib qho hluav taws xob tam sim no dhau los ntawm nws. Qhov no ua rau lub ntsej muag smoother, tshem tawm cov microscopic imperfections, burrs, thiab cov kab mob. Cov txheej txheem yuav pab txhim kho lub raj ntawm qhov chaw tiav los ntawm kev ua kom nws ci ntsa iab thiab smoother dua li cov neeg kho tshuab polishing.
Dab tsi yog Txoj Kev Ua ntawm EP Stainless Seamless Steel Tubes?
Cov txheej txheem ntau lawm rauEP Tubeskoom nrog ntau theem, uas zoo ib yam li kev tsim cov txheej txheem seamless stainless hlau raj, nrog rau qhov sib ntxiv ntawm cov kauj ruam electropolishing los txhim kho nto tiav thiab corrosion kuj. Nov yog cov ntsiab lus ntawm cov kauj ruam tseem ceeb hauv kev tsim EP electropolished seamless stainless hlau raj:
1. Kev xaiv raw khoom
High-quality stainless hlau billets (khoom stainless hlau tuav) raug xaiv raws li lawv cov tshuaj muaj pes tsawg leeg. Common qib rau seamless stainless hlaucov raj muaj xws li 304, 316, thiab lwm yamalloys nrog zoo heev corrosion kuj.
Cov billets yuav tsum ua tau raws li cov qauv tshwj xeeb kom ntseeg tau tias lawv muaj cov khoom siv kho tshuab uas xav tau thiab tiv thaiv corrosion rau cov ntawv thov hauv kev lag luamxws li tshuaj, khoom nojua, thiab electronics.
2. Piercing lossis Extrusion
Stainless hlau billets yog thawj rhuab mus rau ib tug kub kub, ua rau lawv malleable. Tom qab ntawd lub billet yog pierced nyob rau hauv nruab nrab siv ib tug tho zeb los tsim ib tug hollow raj.
Ib tug mandrel (ib tug pas nrig ntev) yog thawb los ntawm qhov chaw ntawm lub billet, tsim ib tug thawj lub qhov, tsim qhov pib ntawm seamless raj.
Extrusion: Lub hollow billet raug thawb los ntawm kev tuag nyob rau hauv kev kub siab, uas ua rau lub seamless raj nrog qhov xav tau qhov ntev.
3. Pilgering
Tom qab tho, lub raj txuas ntxiv elongated thiab zoo li tus extrusion los yog pilgering:
Pilgering: Ib qho kev tuag thiab cov chais yog siv los maj mam txo cov raj txoj kab uas hla thiab phab ntsa thickness, thaum tseem lengthening nws. Cov txheej txheem no ua rau kom lub raj qhov tseeb ntawm cov ntsiab lustxoj kab uas hla, phab ntsa thickness, thiab nto tiav.
4. Kev kos duab txias
Lub raj yog tom qab ntawd dhau los ntawm cov txheej txheem kos duab txias, uas cuam tshuam nrog rub lub raj los ntawm kev tuag kom txo nws txoj kab thiab phab ntsa tuab thaum nce nws qhov ntev.
Cov kauj ruam no txhim kho lub raj qhov tseeb qhov tseeb thiab qhov chaw tiav, ua kom nws smoother thiab ntau yam sib xws hauv qhov loj.
5. Annealing
Tom qab cov txheej txheem kos duab txias, lub raj yog rhuab nyob rau hauv ib qho chaw tswj cua sov rau annealing, uas relieves kev nyuaj siab, softens cov khoom, thiab txhim kho ductility.
Lub raj yog feem ntau annealed nyob rau hauv ib tug tsis muaj oxygen (inert gas los yog hydrogen) cua kom tsis txhob oxidation. Qhov no yog qhov tseem ceeb vim tias oxidation tuaj yeem ua rau lub raj tsis zoo thiab nws cov corrosiontsis kam.
6. Electropolishing (EP)
Lub ntsiab lus ntawm electropolishing yog nqa tawm nyob rau theem no, feem ntau tom qab pickling thiab annealing, ntxiv txhim khu lub raj nto.
Electropolishing yog txheej txheem electrochemical uas lub raj yog raus rau hauv lub da dej electrolyte (feem ntau yog sib xyaw ntawm phosphoric acid thiab sulfuric acid). Ib qho tam sim no dhau los ntawmkev daws, ua rau cov khoom tawg ntawm lub raj ntawm qhov chaw nyob rau hauv kev tswj hwm.
Electropolishing ua haujlwm li cas
Thaum lub sij hawm txheej txheem, lub raj txuas nrog lub anode (zoo electrode) thiab electrolyte rau cathode (tsis zoo electrode). Thaum tam sim no ntws, nws dissolves microscopic peaks nyob rau saum npoo ntawm lub raj, uas ua rau ib tug du, ci, thiab daim iav zoo li tag.
Cov txheej txheem no tshem tawm cov txheej nyias nyias ntawm qhov chaw, tshem tawm qhov tsis zoo, burrs, thiab txhua qhov chaw oxides thaum txhim kho corrosion.
Dab tsi yog qhov zoo ntawm EP Stainless Seamless Steel Tubes?
Dab tsi yog cov ntawv thov ntawm EP Stainless Seamless Steel Tubes?
Pharmaceutical thiab Food Processing: Electropolished Seamless Tubesfeem ntau yog siv rau hauv cov tshuab uas xav tau qhov chaw huv thiab tsis muaj menyuam, xws li kev thauj cov tshuaj, khoom noj, lossis cov khoom siv tshuaj.
Kev lag luam semiconductor:Hauv cov txheej txheem tsim khoom semiconductor, purity thiab smoothness ntawm cov ntaub ntawv yog ib qho tseem ceeb, yog li EP stainless hlau raj feem ntau siv nyob rau hauv high-tech daim ntaub ntawv.
Biotech thiab Medical Devices:Lub npoo du thiab corrosion kuj yog qhov zoo tagnrho rau siv hauv kev kho mob thiab biotech li, qhov twg tsis muaj menyuam thiab kev ua haujlwm ntev yog qhov tseem ceeb.
