Kusukela ekubunjweni kuye kwifomu, uhla lwezinto ezithinta izici zemikhiqizo yensimbi engagqwali.Okunye okucatshangelwayo okubaluleke kakhulu ukuthi yiliphi ibanga lensimbi okufanele lisetshenziswe.Lokhu kuzonquma ububanzi bezimpawu futhi, ekugcineni, kokubili izindleko nempilo yemikhiqizo yakho yensimbi engagqwali.
Ngakho wazi kanjani ukuthi ungaqala kuphi?
Nakuba zonke izinhlelo zokusebenza zihlukile, le mibuzo engu-7 igqamisa ukucatshangelwa okubalulekile ukuze ukusize unciphise izinketho zakho futhi uthole amamaki afaneleka kakhulu izidingo noma isicelo sakho.
1. YILUPHI UHLOBO LOKUMELANA Insimbi YAMI EYIDINGAYO?
Uma ucabanga ngensimbi engagqwali, izinto zokuqala ezifika emqondweni cishe ukumelana nama-asidi nama-chloride--njengalawo atholakala ezimbonini noma ezindaweni zasolwandle.Nokho, ukumelana nezinga lokushisa nakho kubalulekile.
Uma udinga ukumelana nokugqwala, uzofuna ukugwema izinsimbi ze-ferritic ne-martensitic.Amamaki ensimbi engagqwali afanelekile ezindawo ezigqwalile ahlanganisa ama-alloys e-austenitic noma ama-duplex afana namabanga 304, 304L, 316, 316L, 2205, kanye no-904L.
Ezindaweni ezinethempelesha ephezulu, amamaki e-austenitic avamise ukuhamba phambili.Ukuthola ibanga eline-chromium ephezulu, i-silicon, i-nitrogen, nezinto ezingavamile zomhlaba kuzophinde kuguqule ikhono lensimbi lokumelana nezinga lokushisa eliphezulu.Amabanga ajwayelekile ezindawo ezinezinga lokushisa eliphezulu ahlanganisa u-310, S30815, no-446.
Amabanga ensimbi ye-Austenitic nawo alungele izinga lokushisa eliphansi noma izindawo ze-cryogenic.Ukuze uthole ukumelana okwengeziwe, ungabheka amamaki ekhabhoni ephansi noma aphezulu e-nitrogen.Amabanga avamile ezindawo ezinezinga lokushisa eliphansi ahlanganisa 304, 304LN, 310, 316, kanye no-904L.
2. INGABE INSIMBA YAMI IDINGA UKUBUNJWA?
Insimbi engasebenzeki kahle izoba brittle uma isisebenza ngokweqile futhi inikeze ukusebenza okuphansi.Ezimweni eziningi, izinsimbi ze-martensitic azinconywa.Ngaphezu kwalokho, insimbi enokwakheka okuphansi ingase ingasigcini isimo sayo lapho kudingeka ukwakheka okuyinkimbinkimbi noma okuyinkimbinkimbi.
Uma ukhetha ibanga lensimbi, uzofuna ukucabangela uhlobo ongathanda ukuthi lilethwe ngalo.Ukuthi ufuna izinduku, ama-slabs, imigoqo noma amashidi kuzokhawulela izinketho zakho.Isibonelo, izinsimbi ze-ferritic zivame ukudayiswa ngamashidi, izinsimbi ze-martensitic zivame ukuthengiswa emigoqweni noma kuma-slabs, futhi ama-austentic steels atholakala ezinhlobonhlobo ezibanzi kakhulu zamafomu.Amanye amamaki ensimbi atholakala ngezindlela ezihlukahlukene ahlanganisa i-304, 316, 430, 2205, kanye ne-3CR12.
3. INGABE INTSIMBI YAMI IZODINGA UKUCHITHWA?
Ukumachine ngokuvamile akuyona inkinga.Nokho, ukuqina komsebenzi kungaveza imiphumela engahlosiwe.Ukwengezwa kwesibabule kungathuthukisa ukusebenza kahle kodwa kunciphisa ukwakheka, ukushisela kanye nokumelana nokugqwala.
Lokhu kwenza ukuthola ibhalansi phakathi kokuqina komshini kanye nokumelana nokugqwala kube ukucatshangelwa okubalulekile kwezinqubo eziningi zokwenziwa kwensimbi engenasici.Ngokuya ngezidingo zakho, amabanga 303, 416, 430, kanye no-3CR12 anikeza ibhalansi enhle ongakhetha kuyo ukuze unciphise.
4. INGABE NGIDINGA UKUSHIYELA INGQINISO YAMI?
Ukushisela insimbi engagqwali kungaholela enkingeni—okuhlanganisa ukuqhekeka okushisayo, ukuqhekeka kokugqwala kwengcindezi, nokugqwala kwe-intergranular—kuya ngebanga lensimbi esetshenziswayo.Uma uhlela ukushisela insimbi yakho engagqwali, ama-alloys e-austenitic alungile.
Amamaki ekhabhoni ephansi angasiza ngokuqhubekayo ngokushisela kuyilapho izithasiselo, njenge-niobium, zingazinzisa ama-alloys ukugwema ukukhathazeka kokugqwala.Amabanga adumile ensimbi engagqwali yokushisela afaka i-304L, 316, 347, 430, 439 kanye ne-3CR12.
5. INGABE UKWELASHWA OKUSHISA KUDINGEKA?
Uma isicelo sakho sidinga ukwelashwa okushisa, kufanele ucabangele ukuthi amamaki ahlukahlukene ensimbi aphendula kanjani.Izici zokugcina zezinsimbi ezithile zihluke kakhulu ngaphambi nangemva kokwelashwa kokushisa.
Ezimweni eziningi, izinsimbi eziqinisa i-martensitic nezimvula, ezifana no-440C noma 17-4 PH, zinikeza ukusebenza okungcono kakhulu lapho kuphathwa ukushisa.Izinsimbi eziningi ze-austenitic kanye ne-ferritic aziqinile uma sezelashiwe ukushisa ngakho-ke azizona izinketho ezifanele.
6. YIKUPHI AMANDLA ESAMBILI ANGINGAKUHLE EKUFAKA ISICELO SAMI?
Amandla ensimbi ayisici esibalulekile okufanele sicatshangelwe ukuze kwandiswe ukuphepha.Nokho, ukunxeshezelwa ngokweqile kungaholela ezindlekweni ezingadingekile, isisindo, nezinye izici ezimoshayo.Izici zamandla zisethwa ngokukhululekile umndeni wensimbi ngokuhlukahluka okwengeziwe okutholakala kumabanga ahlukene.
7. IYINI IINDLEKO EZIYINKOKHELO KANYE NEZINDLEKO ZONKE ZOKUPHILA KWALESI SESIGCAWU SAMI?
Konke ukucatshangelwa kwangaphambilini kugxila embuzweni obaluleke kakhulu ekukhetheni ibanga lensimbi engagqwali—izindleko zokuphila konke.Ukufanisa amamaki ensimbi engagqwali nendawo oyihlosile, ukusetshenziswa nezimfuneko, ungaqinisekisa ukusebenza okuhlala isikhathi eside kanye nenani eliyingqayizivele.
Qaphela ukuhlaziya ukuthi insimbi izosebenza kanjani esikhathini esihlosiwe sokusetshenziswa nokuthi yiziphi izindleko ezingase zihileleke ekunakekeleni noma ekushintsheni ngaphambi kokunquma.Ukukhawulela izindleko kusengaphambili kungaholela ekusetshenzisweni kwemali okuningi kakhulu empilweni yephrojekthi yakho, umkhiqizo, isakhiwo, noma olunye uhlelo lokusebenza.
Ngenani elikhulu lamamaki ensimbi engagqwali namafomu atholakalayo, ukuba nochwepheshe ozokusiza ukugqamisa izinketho kanye nezingibe ezingaba khona kuyindlela enhle kakhulu yokuqinisekisa ukuthi uthola inani eliphelele lokutshalwa kwensimbi engagqwali.Njengomhlinzeki oholayo wensimbi engagqwali iminyaka engaphezu kwengu-20, i-Jindalai Steel Group izosebenzisa ulwazi lwethu ukuze ikusize ukukuqondisa ohlelweni lokuthenga.Buka uhlu lwethu olubanzi lwemikhiqizo engagqwali ku-inthanethi noma shayela ukuze uxoxe ngezidingo zakho nelungu lethimba lethu.
