Yintoni iNsimbi?
Intsimbi yi-alloy ye-Iron kunye nenqununu (engundoqo) ye-alloying element yiCarbon.Nangona kunjalo, kukho izinto ezingafaniyo kule nkcazo efana ne-interstitial-free (IF) iintsimbi kunye nohlobo lwe-409 ferritic stainless steels, apho i-carbon ithathwa njengento engcolileyo.
Yintoni iAlloy?
Xa izinto ezahlukeneyo zixutywe ngamanani amancinci kwisiseko, imveliso ephumayo ibizwa ngokuba yi-alloy yesiseko.Yiyo loo nto intsimbi iyingxubevange ye-Iron kuba i-Iron yeyona nto isisiseko (engundoqo) kwintsimbi kwaye eyona nto iphambili yokuhlanganisa yiCarbon.Ezinye izinto ezinje ngeManganese, iSilicon, iNickel, iChromium, iMolybdenum, iVanadium, iTitanium, iNiobium, iAluminiyam, njl.
I-Jindalai (i-Shandong) ye-Steel Group Co., Ltd. yingcali kunye nomthengisi ohamba phambili wentsimbi kunye nemivalo yentsimbi / imibhobho / iikhoyili / iipleyiti.Thumela umbuzo wakho kwaye siya kukuvuyela ukubonisana nawe ngobuchule.
Zeziphi iintlobo ezahlukeneyo zentsimbi?
Ngokusekwe kulwakhiwo lweekhemikhali, intsimbi ingahlelwa ngokweendidi ezine (04) ezisisiseko:
● Intsimbi yeCarbon
● Intsimbi engatyiwa
● Intsimbi yentsimbi
● Isixhobo sentsimbi
1. Intsimbi yeCarbon:
Intsimbi yeCarbon yeyona isetyenziswa kakhulu kumashishini kwaye ibalelwa ngaphezulu kwe-90% yemveliso yentsimbi iyonke.Ngokusekwe kumxholo wekhabhoni, iintsimbi zeCarbon zikwahlulwa kwakhona zibe ngamaqela amathathu.
● Intsimbi yeCarbon ephantsi/intsimbi ethambileyo
● Intsimbi yeCarbon ePhakathi
● Intsimbi yeCarbon ephezulu
Umxholo wekhabhoni unikiwe kwitheyibhile engezantsi:
| Hayi. | Uhlobo lwentsimbi ye-carbon | Ipesenti yeCarbon |
| 1 | Intsimbi yeCarbon ephantsi / intsimbi ethambileyo | Ukuya kuthi ga kwi-0.25% |
| 2 | Intsimbi yeKhabhoni ePhakathi | 0.25% ukuya ku-0.60% |
| 3 | Intsimbi yeCarbon ephezulu | 0.60% ukuya kwi-1.5% |
2. Intsimbi engatyiwa:
Insimbi engenasici yintsimbi ye-alloy equkethe i-10.5% yeChromium (Ubuncinci).Insimbi engenasici ibonisa iipropati zokuxhathisa ukubola, ngenxa yokwakheka kwe-Cr2O3 encinci kakhulu kumphezulu wayo.Lo maleko ukwabizwa ngokuba yi-passive layer.Ukwandisa inani leChromium kuya kwandisa ngakumbi ukuxhathisa ukubola kwezinto.Ukongeza kwiChromium, iNickel kunye neMolybdenum nazo zongezwa ukunika iimpawu ezinqwenelekayo (okanye eziphuculweyo).Intsimbi engenastainless ikwaqulethe izixa ezahlukeneyo zeCarbon, iSilicon, kunye neManganese.
Iintsimbi ezingenastainless ziphinda zihlelwe njenge;
1. Iintsimbi zeFerritic eziNgatyiwayo
2. Iintsimbi ze-Martensitic
3. Iintsimbi zeAustenitic ezingatyiwayo
4. Iintsimbi zeDuplex eziNgatyiwayo
5. I-Precipitation-Hardening (PH) Iinsimbi ezingenasici
● I-Ferritic Stainless Steel: Iintsimbi ze-Ferritic ziquka i-Iron-Chromium alloys kunye ne-body-centered body-centered cubic crystal structures (BCC).Ezi ngokuqhelekileyo zimagnetic kwaye azinakwenziwa lukhuni ngonyango lobushushu kodwa zingomelezwa kukusebenza okubandayo.
● I-Austenitic Stainless Steel: Iintsimbi ze-Austenitic zezona zikwazi ukumelana nomhlwa.Ayinamagnetic kwaye ayinyangeki ngobushushu.Ngokubanzi, iintsimbi ze-austenitic zikwazi ukuwelda kakhulu.
● I-Martensitic Stainless Steel: Iintsimbi ze-Martensitic stainless zomelele ngokugqithisileyo kwaye zomelele kodwa azikwazi ukumelana nomhlwa njengezinye iindidi ezimbini.Ezi ntsimbi zisebenza kakhulu, zimagnetic, kwaye ziyanyangeka ngenxa yobushushu.
● I-Duplex Stainless Steels: I-Duplex stainless steel iquka i-microstructure enezigaba ezimbini ezibandakanya iinkozo ze-ferritic kunye ne-austenitic stainless steel (oko kukuthi iFerrite + Austenite).Iintsimbi ze-Duplex zomelele ngokuphindwe kabini njenge-austenitic okanye i-ferritic stainless steels.
● Iintsimbi ze-Precipitation-Hardening (PH): Iintsimbi ze-Precipitation-Hardening (PH) zinamandla aphezulu ngenxa yokuqina kwemvula.
3. Intsimbi yentsimbi
Kwinsimbi ye-alloy, imilinganiselo ehlukeneyo yezinto ezixutywayo zisetyenzisiweyo, ukufezekisa izinto ezinqwenelekayo (eziphuculweyo) ezifana ne-weldability, ductility, machinability, amandla, ukuqina kunye nokumelana nokubola, njl njl.
● I-Manganese – Yongeza amandla kunye nobulukhuni, yehlisa i-ductility kunye ne-weldability.
● I-Silicon - Isetyenziswe njenge-deoxidizers esetyenziswa kwinkqubo yokwenza intsimbi.
● I-Phosphorus - Yongeza amandla kunye nobulukhuni kwaye yehlise i-ductility kunye ne-notch impembelelo yokuqina kwentsimbi.
● Isulfure -Yehlisa ukudumba, impembelelo yenotshi yokuqina, kunye nokuwelda.Ifunyenwe ngendlela ye-sulfide inclusions.
● Ubhedu - ukuxhathisa okuphuculweyo kokutya.
● I-Nickel - Yandisa ukuqina kunye namandla e-Impact yeentsimbi.
● I-Molybdenum - Yandisa ukuqina kunye nokwandisa ukunyanzeliswa kwe-creep of low-alloy steels.
4. Isixhobo sentsimbi
Iintsimbi zesixhobo zinomxholo ophezulu wekhabhoni (0.5% ukuya kwi-1.5%).Umxholo wekhabhoni ophezulu unika ubunzima obuphezulu kunye namandla.Ezi zintsimbi zisetyenziswa kakhulu ukwenza izixhobo kwaye ziyafa.Isixhobo sensimbi sinezixa ezahlukeneyo ze-tungsten, i-cobalt, i-molybdenum, kunye ne-vanadium ukunyusa ubushushu kunye nokumelana nokunxiba, kunye nokuqina kwesinyithi.Oku kwenza ukuba izixhobo zentsimbi zilungele ukusetyenziswa njengezixhobo zokusika kunye nokugrumba.
Iqela le-Jindalai Steel lihlala ligcwele i-inventory engcono kakhulu yeemveliso zentsimbi kwishishini.I-Jindalai inokukunceda ukhethe izinto ezifanelekileyo zentsimbi ukuqinisekisa ukuba ufumana into oyifunayo ngokukhawuleza xa ilixesha lokuthenga.Ukuba ukuthengwa kwezinto zentsimbi kukwikamva lakho elikufutshane, cela ikowuti.Siza kubonelela ngeyona ikufumana kanye iimveliso ozifunayo ngokukhawuleza.
