Ukusuka ekubukeni ukuze kufomu, uhla lwezinto luthinta izici zemikhiqizo yensimbi engenasici. Enye yokucatshangelwa okubaluleke kakhulu yiliphi ibanga lensimbi okufanele lilisebenzise. Lokhu kuzocacisa uhla lwezimpawu futhi, ekugcineni, zombili izindleko nokuphila kwemikhiqizo yensimbi engagqwali.
Ngakho-ke wazi kanjani ukuthi uzoqala kuphi?
Ngenkathi zonke izinhlelo zokusebenza zihlukile, le mibuzo engu-7 igqamisa ukucatshangelwa okubucayi ukukusiza ukunciphisa izinketho zakho futhi uthole amamaki afanelekele izidingo zakho noma isicelo.
1. Uhlobo luni lokumelana nensimbi yami?
Uma ucabanga ngensimbi engenacala, izinto zokuqala ezifika engqondweni kungenzeka ukuthi zimelana nama-acid kanye nama-chlorides - njengalezo ezitholakala ezinhlalulweni zezimboni noma ezindaweni zasemanzini. Kodwa-ke, ukumelana nokushisa kungukucatshangelwa okubalulekile.
Uma udinga ukumelana nokugqwala, uzofuna ukugwema ama-Ferritic and Martititic Steel. Amabanga afanele ensimbi angenasici zamazinga awonakalisayo afaka ama-auntenitic noma ama-duplex alloys anjengeBangani 304, 304l, 316, 36L, 2205, no-904l.
Ngezindawo eziphakeme zokushisa, amamaki e-auntenitic avame kakhulu. Ukuthola ibanga nge-chromium ephezulu, i-silicon, i-nitrogen, kanye nezinto zomhlaba ezingavamile kuzoqhubeka nokushintsha amandla wensimbi wokubekezelela amazinga okushisa aphezulu. Amamaki ajwayelekile ezindawo eziphakeme zokushisa afaka ama-310, S30815, no-446.
Amabanga we-Autenitic ensimbi nawo alungele izindawo zokushisa eziphansi noma eziphansi ze-crygenic. Ngokumelana okungeziwe, ungabheka i-carbon ephansi noma amamaki aphezulu we-nitrogen. Amamaki ajwayelekile ezindawo zokushisa eziphansi afaka u-304, 304LN, 310, 316, no-904l.
2. Ngabe insimbi yami idinga ukwakheka?
Insimbi enokwakheka okungekuhle izoba brittle uma isebenza ngokweqile futhi inikezela ukusebenza okuphansi. Ezimweni eziningi, ama-martensitic steel awanconywa. Ngaphezu kwalokho, insimbi enokwakheka okuphansi kungenzeka ingabambeki ukwakheka kwayo lapho kwakhiwa okuyinkimbinkimbi noma okuyinkimbinkimbi.
Lapho ukhetha ibanga lensimbi, uzofuna ukubheka ifomu ongalithanda ngalo ukulethwe. Noma ngabe ufuna izinduku, ama-slabs, imigoqo noma amashidi azokhawulela izinketho zakho. Isibonelo, ama-Ferritic Steel ajwayele ukuthengiswa emashidini, ama-martensitic steel avame ukuthengiswa ngemigoqo noma kuma-slabs, futhi ama-autentic steel atholakala ezinhlokweni ezazibanzi kakhulu. Amanye amamaki ensimbi atholakala ezinhlobonhlobo zamafomu afaka 304, 316, 430, 2205, ne-3CR12.
3. Ngabe insimbi yami izodinga imishini?
Imishini ayifani nenkinga. Kodwa-ke, ukuqina kokusebenza kungakhiqiza imiphumela engahlosiwe. Ukungezwa kwesibabule kungathuthukisa ukusebenza kwemishini kepha kunciphisa ukwakheka, ukufudumala nokuphikiswa kokugqwala.
Lokhu kwenza ukuthola ukulinganisela phakathi kwemishini nokuphikiswa kokugqwala ukucatshangelwa okubucayi kwezinqubo zensimbi ezingenacala eziningi. Ngokuya ngezidingo zakho, amaBanga 303, 416, 430, futhi i-3CR12 anikele ngebhalansi enhle kusuka kulokho okukhethwa kukho okuncane.
4. Ngabe ngidinga ukwehluleka insimbi yami engenacala?
Insimbi engenacala engagqwali ingaholela enkingeni-kufaka phakathi ukuqhekeka okushisayo, ukuqhekeka kokugqwala okushisayo, ukuqhekeka kokugqwala kwengcindezelo, kanye nokugqwala kokunhlangothi - kuya ngebanga lensimbi elisetshenzisiwe. Uma uhlela ukwehluleka insimbi yakho engenacala, ama-aphoy auntenitic alungile.
Amamaki e-carbon aphansi angakusiza ngokuqhubeka nokushaywa ngokufudumala ngenkathi izengezo, njenge-niobium, kungazinza ama-alloys ukugwema ukukhathazeka kokugqwala. Amamaki athandwayo ensimbi engenasici yokufudumala afaka u-304L, 316, 347, 430, 439 ne-3CR12.
5. Ingabe ukwelashwa okushisa kuyadingeka?
Uma uhlelo lwakho lokusebenza ludinga ukwelashwa okushisa, kufanele ubheke ukuthi amabanga ahlukahlukene ensimbi aphendula kanjani. Izici zokugcina zensimbi ethile ziyehluka kakhulu ngaphambi nangemva kokwelashwa okushisa.
Ezimweni eziningi, ama-martensitic kanye ne-teresiture arrening steel, njenge-440c noma ngo-17-4 ph, anikeze ukusebenza okuhle kakhulu lapho ukushisa kuphathwe. Ama-auntenitic amaningi ase-Auntenitic kanye ne-Ferritic angenasisekelo awalondolozi lapho ukushisa okuphathwe ngakho-ke akuzona izinketho ezifanele.
6. Imaphi amandla ensimbi alungele ukusetshenziswa kwami?
Amandla wensimbi ayinto ebalulekile okufanele ucatshangelwe ukukhulisa ukuphepha. Kodwa-ke, ukunqoba kungaholela ezindlekweni ezingafuneki, isisindo, nezinye izinto ezichithekayo. Izici zamandla zibekwa ngokukhululekile ngumndeni wensimbi ngokuhlukahluka okutholakalayo kumabanga ahlukene.
7. Ithini izindleko ezingaphambilini nezindleko zokuphila kwale nsimbi esimweni sami?
Konke ukucatshangelwa kwangaphambilini okuphakelayo embuzweni obaluleke kakhulu ekukhetheni izindleko ze-stacken grade-life. Ukufanisa amamaki ensimbi angenasici endaweni yakho okuhlosiwe, ukusetshenziswa nezidingo, ungaqinisekisa ukusebenza okuhlala isikhathi eside nenani elihlukile.
Nakekela ukuhlaziya ukuthi insimbi izokwenza kanjani isikhathi esihlosiwe sokusetshenziswa nokuthi yiziphi izindleko ezingahileleka ekunakekelweni noma esikhundleni ngaphambi kokuthatha isinqumo. Ukunciphisa izindleko ngaphambili kungahle kube nokusebenzisa imali eningi ngokuphila kwephrojekthi yakho, umkhiqizo, isakhiwo, noma esinye isicelo.
Ngenombolo enkulu yamabanga angenasici namafomu atholakalayo, anochwepheshe wokusiza ukugqamisa izinketho nezingqinamba kuyindlela enhle kakhulu yokuqinisekisa ukuthi uthola inani elifanele lokutshala imali engagqwali. Njengomhlinzeki oholayo wensimbi engenasici iminyaka engaphezu kwengu-20, iJinganiai Steel Iqembu izothuthukisa ulwazi lwethu ukukusiza ukukuhola ngenqubo yokuthenga. Bheka uhlu lwethu olubanzi lwemikhiqizo engenacala online noma shayela ukuxoxa ngezidingo zakho nelungu leqembu lethu.
