Yintoni iNsimbi?
Intsimbi yi-alloy ye-Iron kwaye into ephambili (ephambili) yokudibanisa yiCarbon. Nangona kunjalo, kukho ezinye izinto ezingafaniyo nale nkcazo njengezintsimbi ezingenayo i-interstitial-free (IF) kunye nezintsimbi ezingenasici ze-ferritic type 409, apho ikhabhoni ithathwa njengento engcolileyo.
Yintoni i-Alloy?
Xa izinto ezahlukeneyo zixutywa ngobuninzi obuncinci kwi-base element, imveliso ephumayo ibizwa ngokuba yi-alloy ye-base element. Ngenxa yoko intsimbi yi-alloy ye-Iron kuba i-Iron yinto esisiseko (inxalenye ephambili) kwintsimbi kwaye into ephambili yokudibanisa yiCarbon. Ezinye izinto ezifana neManganese, iSilicon, iNickel, iChromium, iMolybdenum, iVanadium, iTitanium, iNiobium, iAluminium, njl. nazo zongezwa ngobuninzi obahlukeneyo ukuvelisa amanqanaba ahlukeneyo (okanye iintlobo) zeNtsimbi.
IJindalai (Shandong) Steel Group Co., Ltd. yingcali kwaye ikhokela umthengisi wentsimbi kunye neebha/iipayipi/iikhoyili/iipleyiti zentsimbi engagqwaliyo. Thumela umbuzo wakho kwaye siya kukuvuyela ukubonisana nawe ngobuchule.
Ziziphi iintlobo ezahlukeneyo zentsimbi?
Ngokusekelwe kwiikhemikhali ezisetyenzisiweyo, iNtsimbi inokwahlulwahlulwa ibe ziintlobo ezine (04) ezisisiseko:
● Intsimbi yeCarbon
● Intsimbi Engagqwaliyo
● Intsimbi ye-alloy
● Isixhobo Sentsimbi
1. Intsimbi yekhabhoni:
Intsimbi yekhabhoni yeyona isetyenziswa kakhulu kumashishini kwaye ibangela ngaphezulu kwe-90% yemveliso iyonke yentsimbi. Ngokusekelwe kumxholo wekhabhoni, iintsimbi zekhabhoni zahlulwe ngokwamaqela amathathu.
● Intsimbi Ephantsi Yekhabhoni/Intsimbi Encinci
● Intsimbi yeCarbon ephakathi
● Intsimbi yeCarbon ephezulu
Umxholo wekhabhoni unikwe kwitheyibhile engasezantsi:
| Hayi. | Uhlobo lwentsimbi yekhabhoni | Ipesenti yeKhabhoni |
| 1 | Intsimbi yeCarbon ephantsi/Intsimbi ethambileyo | Ukuya kuthi ga kwi-0.25% |
| 2 | Intsimbi yeKhabhoni ephakathi | 0.25% ukuya kwi-0.60% |
| 3 | Intsimbi yeCarbon ephezulu | 0.60% ukuya kwi-1.5% |
2. Intsimbi Engagqwaliyo:
Intsimbi engagqwali yintsimbi ye-alloy equlethe i-10.5% yeChromium (Ubuncinci). Intsimbi engagqwali ibonisa iimpawu zokuxhathisa ukugqwala, ngenxa yokwenziwa komaleko omncinci kakhulu weCr2O3 kumphezulu wayo. Olu maleko lukwaziwa ngokuba ngumaleko ongasebenziyo. Ukwandisa ubungakanani beChromium kuya kwandisa ngakumbi ukuxhathisa ukugqwala kwezinto. Ukongeza kwiChromium, iNickel kunye neMolybdenum zongezwa ukunika iimpawu ezifunwayo (okanye eziphuculweyo). Intsimbi engagqwali ikwanazo nezixa ezahlukeneyo zeCarbon, iSilicon, kunye neManganese.
Iintsimbi ezingenasici zihlelwa ngakumbi ngolu hlobo;
1. Iintsimbi ezingasebenziyo zeFerritic
2. Iintsimbi ezingasebenziyo zeMartensitic
3. Iintsimbi Ezingenasici zaseAustenitic
4. Iintsimbi eziNcinci zeDuplex
5. Iintsimbi Ezingenasici Zokuna kweNtlanzi (PH)
● Intsimbi Engagqwaliyo yeFerritic: Iintsimbi zeFerritic zenziwe ngee-alloys ze-Iron-Chromium ezinezakhiwo ze-cubic crystal (BCC) ezigxile emzimbeni. Ezi zihlala zinomtsalane kwaye azinakuqina ngonyango lobushushu kodwa zinokomelezwa ngokusebenza ngokubandayo.
● Intsimbi Engagqwaliyo E-Austenitic: Iintsimbi ze-Austenitic ziyakwazi ukumelana nokugqwala. Azinamagnethi kwaye azinyangeki kubushushu. Ngokubanzi, iintsimbi ze-austenitic ziyakwazi ukuthungelwa kakhulu.
● Intsimbi Engagqwaliyo yeMartensitic: Iintsimbi ezingqwaliyo zeMartensitic ziqinile kakhulu kwaye ziqinile kodwa azikwazi ukumelana nokugqwala njengezinye iindidi ezimbini. Ezi ntsimbi zisebenza ngomatshini kakhulu, zinamandla ombane, kwaye ziyanyangeka kubushushu.
● Iintsimbi Ezingenasici Ezimbini: Intsimbi Engenasici Embini inesakhiwo esincinci esinezigaba ezibini esiquka iinkozo zentsimbi engacinywanga ye-ferritic kunye ne-austenitic (oko kukuthi i-Ferrite + i-Austenite). Iintsimbi Ezimbini zinamandla aphindwe kabini kuneentsimbi ezingacinywanga ze-austenitic okanye ze-ferritic.
● Ukuqina Kwemvula (PH) Iintsimbi Ezingagqwaliyo: Ukuqina Kwemvula (PH) Iintsimbi Ezingagqwaliyo zinamandla aphezulu kakhulu ngenxa yokuqina kwemvula.
3. Intsimbi ye-alloy
Kwintsimbi ye-alloy, kusetyenziswa umlinganiselo owahlukeneyo wezinto ezixutyiweyo, ukufezekisa iipropati ezinqwenelekayo (eziphuculweyo) ezifana nokuxinana, ukuguquguquka, ukuqina, amandla, ukuqina kunye nokumelana nokugqwala, njl. Ezinye zezinto ezixutyiweyo ezisetyenziswa kakhulu kunye neziphumo zazo zezi zilandelayo;
● I-Manganese – Yonyusa amandla nokuqina, inciphisa ukuguguleka kunye nokudityaniswa.
● I-Silicon – Isetyenziswa njenge-deoxidizers esetyenziswa kwinkqubo yokwenza intsimbi.
● I-Phosphorus – Yonyusa amandla nobunzima kwaye inciphisa ukuguguleka kunye nokuqina kwentsimbi.
● I-Sulfur –Inciphisa ukuguguleka, ukuqina kwe-notch impact, kunye nokudityaniswa. Ifumaneka ngohlobo lwe-sulfide inclusions.
● Ithusi – ukumelana nokugqwala okuphuculweyo.
● I-Nickel – Yonyusa ukuqina kwayo kunye namandla eentsimbi.
● I-Molybdenum – Yonyusa ukuqina kwayo kwaye yonyusa ukumelana nokuqhekeka kweentsimbi ezine-alloy ephantsi.
4. Isixhobo sentsimbi
Iintsimbi zezixhobo zinomxholo ophezulu wekhabhoni (0.5% ukuya kwi-1.5%). Umxholo ophezulu wekhabhoni unika ubulukhuni namandla aphezulu. Ezi ntsimbi zisetyenziswa kakhulu ekwenzeni izixhobo kunye needayi. Iintsimbi zezixhobo ziqulathe ubungakanani obahlukeneyo be-tungsten, i-cobalt, i-molybdenum, kunye ne-vanadium ukwandisa ubushushu kunye nokumelana nokuguguleka, kunye nokuqina kwesinyithi. Oku kwenza iintsimbi zezixhobo zilungele kakhulu ukusetyenziswa njengezixhobo zokusika nezokomba.
