Kwihlabathi lanamhlanje lemizi-mveliso, iintambo zentsimbi engagqwaliyo zidlala indima ebalulekileyo ekuqinisekiseni ukomelela, ukhuseleko, kunye nokuqina kumacandelo ahlukeneyo - ukusuka kubunjineli baselwandle ukuya ekucutshungulweni kweekhemikhali kunye nokuhlolwa kweoyile elwandle. Phakathi kweendlela ezininzi zentsimbi engagqwaliyo ezikhoyo,Intambo yocingo lwentsimbi engagqwaliyo ye-2205 Duplexifumene ingqwalasela emangalisayo ngenxa yokwahluka kwayoisakhiwo se-micro-phase esinezigaba ezimbini.
Olu yilo lukhethekileyo lwesinyithi lunika intambo ye-2205 Duplex ibhalansi ebalaseleyo yamandla kunye nokumelana nokugqwala, nto leyo eyenza ukuba ibe ngcono kunemigangatho yesiqhelo ye-austenitic efana ne-304 kunye ne-316.I-SakySteel, sigxile ekuveliseni iintambo zentsimbi engagqwaliyo ezimbini ezisebenza kakuhle ezihlangabezana neemfuno ezingqongqo zamashishini ehlabathi.
Yintoni i-2205 Duplex Stainless Steel?
I-2205 Duplex Stainless Steel, echazwe njengeI-UNS S32205 / EN 1.4462, yi-alloy enamanqanaba amabini eyenziwe ngomlinganiselo olinganayo wei-austenitekwayei-ferriteOlu lwakhiwo lulungeleleneyo lungundoqo kwigama lalo — “duplex.”
-
Isigaba se-Austenitic:inika ukuqina, ukuguquguquka, kunye nokumelana nokugqwala.
-
Isigaba seFerritic:inika amandla, ubulukhuni, kunye nokumelana nokuqhekeka koxinzelelo lokugqwala.
Izinto eziphumayo zibonisa iipropati zoomatshini kunye nokumelana nokugqwala ezidlula ezo zentsimbi ezisemgangathweni ezingenasici ngelixa zigcina iindleko zisebenza kakuhle.
Ingcaciso yeNzuzo yeSimo seMikroskopu
Amandla okwenyaniIntambo yocingo lwentsimbi engagqwaliyo ye-2205 Duplexikwisakhiwo sayo esincinci. Makhe sihlolisise indlela le nkqubo yesigaba esiphindwe kabini ephucula ngayo ukusebenza kwayo:
1. Umlinganiselo oPhezulu wamandla ukuya kubunzima
Isigaba se-ferritic sibonelela ngesivuno esiphezulu kunye namandla okutsalwa, ngelixa isigaba se-austenitic siqinisekisa ukuguquguquka kunye nokuqina. Olu dibaniso lunika i-2205 Duplex phantseamandla okuvelisa kabiniyentsimbi engagqwaliyo engama-304 okanye engama-316, evumela abayili ukuba basebenzise iintambo ezinobubanzi obuncinci ngaphandle kokubeka emngciphekweni amandla okuthwala umthwalo.
2. Ukumelana Nokugqwala Okuphuculweyo
Isakhiwo esincinci sithintela ukugqwala kwendawo ethile, ngakumbiukugxushakwayeumhlwa womqolomba, ezihlala zisenzeka kwiindawo ezityebileyo zekloridi ezifana namanzi olwandle okanye izityalo zeekhemikhali. Ubukho obulinganayo be-chromium (22%) kunye ne-molybdenum (3%) kunceda ukugcina ifilimu ekhuselayo phezu komhlaba, nokuba kwiimeko ze-asidi okanye ze-saline.
3. Ukuxhathisa ukuqhekeka koxinzelelo (SCC)
Enye yezona ngxaki zinkulu kwintsimbi engagqwaliyo kwiindawo zaselwandle nakwiindawo zeoyile yi-SCC ebangelwa yi-chloride. Ngenxa yesigaba sayo se-ferrite, imiboniso ye-2205 Duplexukumelana okubalaseleyokolu hlobo lokusilela, okuqinisekisa uzinzo lwexesha elide kuzo zombini izicelo zoxinzelelo kunye nokushukuma.
4. Ukumelana nokudinwa
Kwiindawo ezitshintshayo, ezinje ngee-elevator, ii-cranes, okanye iinkqubo zokuphakamisa ulwandle, iintambo zentambo zichatshazelwa kukugoba nokulayisha okuphindaphindiweyo. Isakhiwo se-duplex microstructure sinika ukumelana nokudinwa okugqwesileyo, okwenza ukuba ihlale ixesha elide phantsi koxinzelelo olujikelezayo kuneentsimbi ezingenasici zesigaba esinye.
5. Ukuphuculwa kokudityaniswa kunye nozinzo lwesakhiwo
Nangona ukuwelda kunokutshintsha ibhalansi yesigaba see-alloys ezininzi, i-2205 Duplex igcina isakhiwo esizinzileyo xa sicutshungulwa ngokuchanekileyo. Amandla ayo okumelana nokuhlukana kwesigaba ngexesha lokuwelda aqinisekisa ukusebenza okuzinzileyo kunye namandla kulo lonke isakhiwo sentambo.
Indlela iMicrostructure echaphazela ngayo ukusebenza kwentambo yentambo
Ukudibanisa izigaba ze-ferrite kunye ne-austenite kunikaIntambo yocingo lwentsimbi engagqwaliyo ye-2205 Duplexintsebenziswano ekhethekileyo eguqulela kwiingenelo ezinokulinganiswa ekusebenzeni kwehlabathi lokwenyani.
