Iyini insimbi?
Insimbi iyingxubevange ye-Iron futhi into eyinhloko (eyinhloko) ehlanganisa i-Carbon. Kodwa-ke, kukhona okuhlukile kule ncazelo njengezinsimbi ze-interstitial-free (IF) kanye nohlobo lwezinsimbi ezingenasici ze-ferritic ezingu-409, lapho ikhabhoni ibhekwa njengokungcola.
Iyini i-Alloy?
Uma izakhi ezihlukene zixutshwa ngamanani amancane ku-elementi yesisekelo, umkhiqizo owumphumela ubizwa ngokuthi i-alloy ye-base element. Ngakho-ke insimbi iyingxube ye-Iron ngoba i-ayoni iyingxenye eyisisekelo (ingxenye eyinhloko) ensimbi futhi into eyinhloko ehlanganisa i-Carbon. Ezinye izakhi ezifana ne-Manganese, i-Silicon, i-Nickel, i-Chromium, i-Molybdenum, i-Vanadium, i-Titanium, i-Niobium, i-Aluminium, njll. nazo zengezwa ngamanani ahlukahlukene ukuze kukhiqizwe amabanga ahlukene (noma izinhlobo) Zensimbi.
I-Jindalai (Shandong) Steel Group Co., Ltd. iyingcweti futhi ingumhlinzeki oholayo wezinsimbi/amapayipi/amakhoyili/amapuleti ensimbi nensimbi engagqwali. Thumela uphenyo lwakho futhi sizokujabulela ukubonisana nawe ngobuchwepheshe.
Yiziphi Izinhlobo Ezihlukene Zensimbi?
Ngokusekelwe ekwakhiweni kwamakhemikhali, insimbi ingahlukaniswa ngezinhlobo ezine (04) eziyisisekelo:
● Insimbi Yekhabhoni
● Insimbi Engagqwali
● Insimbi ye-alloy
● Insimbi Yensimbi
1. Insimbi Yekhabhoni:
I-Carbon steel iyinsimbi esetshenziswa kakhulu ezimbonini futhi yenza ngaphezu kwama-90% okukhiqizwa kwensimbi okuphelele. Ngokusekelwe kokuqukethwe kwekhabhoni, izinsimbi zeCarbon ziphinde zihlukaniswe ngamaqembu amathathu.
● Insimbi Yekhabhoni Ephansi/Insimbi Emaphakathi
● Insimbi Yekhabhoni Emaphakathi
● Insimbi Ephakeme Yekhabhoni
Okuqukethwe kwekhabhoni kunikezwa kuthebula elingezansi:
| Cha. | Uhlobo lwensimbi ye-carbon | Iphesenti Lekhabhoni |
| 1 | Insimbi Yekhabhoni Ephansi/Insimbi Emaphakathi | Kufika ku-0.25% |
| 2 | Insimbi Yekhabhoni Emaphakathi | 0.25% ukuya ku-0.60% |
| 3 | High Carbon steel | 0.60% ukuya ku-1.5% |
2. Insimbi Engagqwali:
Insimbi engagqwali iyinsimbi eyingxubevange equkethe u-10.5% weChromium (Okungenani). Insimbi engagqwali ibonisa izakhiwo zokumelana nokugqwala, ngenxa yokwakheka kongqimba oluncane kakhulu lwe-Cr2O3 ebusweni bayo. Lesi sendlalelo saziwa nangokuthi isendlalelo sokwenziwa. Ukwenyusa inani le-Chromium kuzothuthukisa ukumelana nokugqwala kwento. Ngokungeziwe ku-Chromium, i-Nickel ne-Molybdenum nazo zengezwa ukuze kudluliselwe izakhiwo ezifiselekayo (noma ezithuthukisiwe). Insimbi engagqwali futhi iqukethe amanani ahlukahlukene eKhabhoni, iSilikoni, neManganese.
Izinsimbi ezingenasici zihlukaniswa futhi ngokuthi;
1. Izinsimbi Ezingenasici zeFerritic
2. I-Martensitic Stainless Steels
3. I-Austenitic Stainless Steels
4. I-Duplex Stainless Steels
5. Izinsimbi ezingagqwali (PH) zokuzinza kwemvula
● I-Ferritic Stainless Steel: Izinsimbi ze-Ferritic zihlanganisa ama-alloys e-Iron-Chromium anezinhlaka zekristalu ezimaphakathi nomzimba (BCC). Lezi ngokuvamile zikazibuthe futhi azikwazi ukwenziwa lukhuni ukwelashwa kokushisa kodwa zingaqiniswa ukusebenza okubandayo.
● I-Austenitic Stainless Steel: Izinsimbi ze-Austenitic zimelana nokugqwala. Ayinazibuthe futhi ayilaphekeki. Ngokuvamile, izinsimbi ze-austenitic zikwazi ukushisela kakhulu.
● I-Martensitic Stainless Steel: Izinsimbi ezingenasici ze-Martensitic ziqine ngokwedlulele futhi ziqinile kodwa azikwazi ukumelana nokugqwala njengezinye izigaba ezimbili. Lezi zinsimbi zikwazi ukusebenza kahle kakhulu, zikazibuthe, futhi ziyakwazi ukwelapheka.
● I-Duplex Stainless Steels: Insimbi engagqwali e-Duplex iqukethe i-microstructure enezigaba ezimbili ehlanganisa izinhlamvu zensimbi engagqwali ye-ferritic ne-austenitic (okungukuthi, i-Ferrite + Austenite). Izinsimbi ze-Duplex cishe ziqine ngokuphindwe kabili njengezinsimbi ezingenasici ze-austenitic noma ze-ferritic.
● Izinsimbi Ezingenazimvula Zemvula (PH): I-Precipitation-Hardening (PH) Izinsimbi Ezingenasici zinamandla aphezulu kakhulu ngenxa yokuqina kwemvula.
3. I-alloy Steel
Ensimbi ye-alloy, izilinganiso ezihlukene zezakhi ze-alloying zisetshenziswa, ukuze kuzuzwe izici ezifiselekayo (ezithuthukisiwe) ezifana nokushisela, i-ductility, machinability, amandla, ukuqina nokumelana nokugqwala, njll Ezinye zezinto ezisetshenziswa kakhulu ze-alloying kanye nemiphumela yazo kanje;
● I-Manganese - Yandisa amandla nobulukhuni, yehlisa i-ductility kanye nokushisela.
● I-Silicon - Isetshenziswa njengama-deoxidizer asetshenziswa enqubweni yokwenza insimbi.
● I-Phosphorus - Yenyusa amandla nobulukhuni futhi yehlise ukudumba kanye nokuqina komthelela wenotshi wensimbi.
● Isibabule -Yehlisa i-ductility, ukuqina komthelela we-notch, kanye nokushisela. Itholakala ngesimo se-sulfide inclusions.
● Ithusi – ukumelana nokugqwala okuthuthukisiwe.
● I-Nickel - Yenyusa ukuqina namandla Omthelela ezinsimbi.
● I-Molybdenum - Yenyusa ukuqina futhi ithuthukise ukumelana nokunyakaza kwezinsimbi ezine-alloy ephansi.
4. Insimbi Yensimbi
Izinsimbi zamathuluzi zinokuqukethwe okuphezulu kwekhabhoni (0.5% kuya ku-1.5%). Okuqukethwe kwekhabhoni ephezulu kunikeza ubulukhuni obuphakeme namandla. Lezi zinsimbi zisetshenziswa kakhulu ukwenza amathuluzi futhi ziyafa. Insimbi yamathuluzi iqukethe amanani ahlukahlukene e-tungsten, i-cobalt, i-molybdenum, ne-vanadium ukukhulisa ukumelana nokushisa nokugqoka, nokuqina kwensimbi. Lokhu kwenza izinsimbi zamathuluzi zilungele ukusetshenziswa njengamathuluzi okusika nawokubhoboza.
I-Jindalai Steel Group ihlala igcwele i-inventory ehamba phambili yemikhiqizo yensimbi embonini. I-Jindalai ingakusiza ukuthi ukhethe izinto zensimbi ezifanele ukuze uqiniseke ukuthi uthola okudingayo ngokushesha okukhulu uma sekuyisikhathi sokuthenga. Uma ukuthengwa kwezinto zensimbi kusesikhathini esizayo esiseduze, cela isaphulelo. Sizohlinzeka ngeyokutholela yona kanye imikhiqizo oyidingayo ngokushesha.
