Yintoni i-Electropolished (EP) ye-Stainless Steel Seamless Tube
Electropolishingyinkqubo ye-electrochemical esusa umaleko omncinci wezinto ezivela kumphezulu wetyhubhu yensimbi engenasici. IEP Stainless Steel iThubhu engenamthungountywiliselwa kwisisombululo se-electrolytic, kwaye umsinga wombane udlula kuwo. Oku kubangela ukuba umphezulu ube mtyibilizi, ususa ukungafezeki kwe-microscopic, i-burrs, kunye nongcoliseko. Inkqubo inceda ekuphuculeni umphezulu womphezulu wetyhubhu ngokuwenza uqaqambe kwaye ube mpuluswa kunendlela eqhelekileyo yokupolisha ngoomatshini.
Yeyiphi iNkqubo yoKwenza yeeMibhobho zentsimbi ezingenamthungo zeEP?
Inkqubo yemveliso yeEP Imibhobhoibandakanya izigaba ezininzi, ezifana nokuveliswa kweetyhubhu zentsimbi ezingenamthungo ezisemgangathweni, kunye nokongezwa kwesinyathelo se-electropolishing ukuphucula umphezulu wokugqiba kunye nokumelana nokubola. Nantsi isishwankathelo samanyathelo aphambili ekwenzeni i-EP electropolished seamless steel stainless tubes:
1. UKhetho lweMathiriyeli ekrwada
Iibhilidi zetsimbi ezikumgangatho ophezulu (iintsimbi eziqinileyo ezingenasici) zikhethwa ngokusekelwe kwimichiza yazo. Amabanga aqhelekileyo entsimbi engenamthungoiityhubhu ziquka 304, 316, kunye nezinyeiialloyi ezinokumelana nokugqwesa okugqwesileyo.
Iibhilithi kufuneka zihlangabezane nemigangatho ethile ukuqinisekisa ukuba zineempawu ezifunekayo zoomatshini kunye nokuchasana nokubola kwezicelo kumashishini.njengamachiza, ukutyaukusetyenzwa, kunye ne-electronics.
2. Ukugqobhoza okanye Ukukhupha
Iibhilithi zensimbi ezingenasici ziqala ukufudunyezwa kwiqondo lobushushu eliphezulu, zibenza zibe lula. Ibillet ke igqojozwe embindini kusetyenziswa ilitye lokusila ukwenza umbhobho ongenanto.
I-mandrel (intonga ende) ityhilwa embindini we-billet, idala umngxuma wokuqala, okwenza isiqalo setyhubhu engenamthungo.
I-Extrusion: I-billet egobileyo ityhalwa kwidayizi phantsi koxinzelelo oluphezulu, okukhokelela kwityhubhu engenamthungo enemilinganiselo efunekayo.
3. Ukuphanga
Emva kokugqobhoza, ityhubhu iye yolulwa ngakumbi kwaye ibunjwe nge-extrusion okanye i-pilgering:
I-Pilgering: Uthotho lwee-dies and rollers zisetyenziselwa ukunciphisa kancinci kancinci ubukhulu betyhubhu kunye nobukhulu bodonga, ngelixa ikwandiswa. Le nkqubo inyusa ukuchaneka kombhobho ngokwemiqathangoububanzi, ubukhulu bodonga, kunye nokugqitywa komphezulu.
4. Umzobo obandayo
Umbhobho ke udlula kwinkqubo yokudweba ebandayo, ebandakanya ukutsala ityhubhu ngokufa ukunciphisa ububanzi kunye nobukhulu bodonga ngelixa ukwandisa ubude bayo.
Eli nyathelo liphucula ukuchaneka komgangatho wetyhubhu kunye nokugqitywa komphezulu, kuyenza ibe mtyibilizi kwaye ifane ngobukhulu.
5. Ukucoca
Emva kwenkqubo yokudweba ebandayo, ityhubhu ifudunyezwa kwisithando somlilo esilawulwayo ukuze i-annealing, ekhulula uxinzelelo lwangaphakathi, ithambisa izinto eziphathekayo, kwaye iphucule i-ductility.
I-tube isoloko ifakwe kwi-oxygen-free (igesi ye-inert okanye i-hydrogen) emoyeni ukuphepha i-oxidation. Oku kubalulekile kuba i-oxidation inokuphazamisa inkangeleko yetyhubhu kunye nokuhlwa kwayoukuxhathisa.
6. I-Electropolishing (EP)
Inyathelo elichazayo le-electropolishing lenziwa kweli nqanaba, ngokuqhelekileyo emva kokucholwa kunye nokufakwa kwe-annealing, ukunyusa ngakumbi umphezulu wetyhubhu.
I-Electropolishing yinkqubo ye-electrochemical apho ityhubhu ibhaptizwa kwindawo yokuhlambela i-electrolyte (ngokuqhelekileyo umxube we-phosphoric acid kunye ne-sulfuric acid). Umsinga udlula kwiisisombululo, esibangela ukuba izinto zinyibilike kumphezulu wombhobho ngendlela elawulwayo.
Indlela i-Electropolishing esebenza ngayo
Ngethuba le nkqubo, ityhubhu ixhunywe kwi-anode (i-electrode enhle) kunye ne-electrolyte kwi-cathode (i-electrode engalunganga). Xa iqukuqela langoku, inyibilikisa iincopho ze-microscopic kumphezulu wetyhubhu, okukhokelela kwisiphelo esigudileyo, esicwebezelayo nesifana nesipili.
Le nkqubo isusa ngokufanelekileyo umaleko obhityileyo ukusuka kumphezulu, isusa ukungafezeki, i-burrs, kunye nayo nayiphi na i-oxides yomhlaba ngelixa iphucula ukuxhathisa kwe-corrosion.
Ziziphi izinto eziluncedo ze-EP Stainless Steel Tubes?
Zeziphi ii-aplikeshini ze-EP ye-Stainless Steel Tubes?
Ukwenziwa kweMichiza kunye noKutya: Imibhobho engenamthungo yombaneziqhele ukusetyenziswa kwiinkqubo ezifuna indawo ecocekileyo nengenazintsholongwane, njengokuthuthwa kweekhemikhali, ukutya, okanye iimveliso zamayeza.
Ishishini leSemiconductor:Kwinkqubo yokuvelisa i-semiconductor, ukucoceka kunye nokugudiswa kwezinto zibalulekile, ngoko ke iibhubhu zensimbi ezingenasici ze-EP zihlala zisetyenziswa kwizicelo eziphezulu.
Izixhobo zeBiotech kunye nezoNyango:Umphezulu ogudileyo kunye nokumelana nokubola kulungele ukusetyenziswa kwizixhobo zonyango kunye ne-biotech, apho ubunyumba kunye nokuphila ixesha elide kubalulekile.

Umbhobho weZR sele ithatha imilinganiselo engqongqo yemathiriyeli ekrwada, inkqubo ye-electropolishing, ukucocwa kwamanzi acocekileyo, kunye nokupakishwa kwigumbi lokucoca ukuthintela ngokufanelekileyo iintsalela ezingcolisayo kunye nokufezekisa uburhabaxa obungcono, ukucoceka, ukuxhathisa ukubola kunye ne-weldability ye-tubing yensimbi engenasici ye-EP. I-ZR Tube yensimbi engenasici ye-EP tubing isetyenziswa ngokubanzi ekucocekeni okuphezulu kunye ne-ultra high purity fluid systems kwi-semiconductor, amayeza, iikhemikhali ezintle, ukutya kunye nokusela, ukuhlalutya kunye namanye amashishini. Ukuba uneemfuno ze-EP ityhubhu kunye nokufakwa, wamkelekile ukuba uqhagamshelane nathi.
