I-Faq Encane Engaziwa Yensimbi Engagqwali

1. Akumele kube yinsimbi engagqwali uzibuthe ongayikhanga.

Lokhu kungukungaqondi okukhulu emqondweni wabantu! Kungashiwo ukuthi uma uya kunoma yimuphi umthengisi wehadiwe, umphathi uzokutshela kanjalo. Uma uyakukholwa, empeleni ngabe unephutha. Yimaphi odonsa angaheha akuyona insimbi engagqwali. (Qaphela, kukhona amagama amathathu hhayi kulo musho) Insimbi engagqwali ingahlukaniswa ngezigaba eziningi, phakathi kwazo izindlela ezisetshenziswa kakhulu zokuhlukanisa i-austenite, ferrite, duplex, martensite, ukuqina kwezulu nezinye izigaba ezinhlanu. Phakathi kwabo, insimbi engagqwali ye-austenitic kuphela ayinamandla kazibuthe, kepha lolu hlobo lwensimbi engagqwali lubanga iningi lemakethe yensimbi engenasici (phambilini, ibingaphezu kwama-70%, manje kulinganiselwa ukuthi ingama-60%, futhi kuzoba ngaphansi kwama-50% ngokuzayo), futhi isetshenziswa kakhulu. Ezinye izinto zensimbi zinamandla kazibuthe, yingakho imakethe yasekhaya yaseChina isebenzisa uzibuthe ukuhlukanisa insimbi engagqwali. Kodwa ezinye izinhlobo zensimbi engenasici zinamandla kazibuthe. Isibonelo, ezikhathini eziningi uya ezindaweni zokudlela ezisezingeni eliphakeme ukuzama lezo zicucu zensimbi engagqwali ezicwebezelayo ngomazibuthe. Zivame ukuba kazibuthe. Eqinisweni, kungenzeka ukuthi ziyinsimbi engenasici ye-martensitic, futhi insimbi engagqwali yamapayipi wokukhipha imoto nayo inamandla. Kuyi-ferritic.

I-Ni ivame ukungezwa ku-austenitic insimbi engagqwali, futhi intengo yomhlaba yamanje ye-Ni iphezulu kakhulu. Ngakho-ke, umkhuba omkhulu wokuthuthuka wensimbi engagqwali uyonga kanjani i-nickel. Enye yezindlela ezinhle ukuthuthukisa insimbi engagqwali ye-ferritic ne-duplex. Ngakho-ke, ngokuzayo kuzoba khona insimbi engagqwali eningi engadonswa odonsa.

2. Insimbi engagqwali ngeke igqwale?

Umphakathi usenokungaqondi okukhulu, okungukuthi, insimbi engagqwali ngeke igqwale. Eqinisweni, ngithathe izinto eziningi kakhulu mayelana nokugqwala kwensimbi engagqwali. Futhi ingxenye enkulu yazo zonke lezi zingozi zensimbi engagqwali engizithathile kungenxa yokuthi abasebenzisi bebengazi ngokwanele ngensimbi engagqwali. Abazange bacabangele izici zezinto zensimbi ezingenasici lapho bekhetha izinto zokwakha. Ukuhlukunyezwa kwensimbi engagqwali kudale ukugqwala okungavamile kwensimbi engagqwali.

Njengoba sonke sazi, esimweni somkhathi jikelele, inqobo nje uma ifanelekile (ngokuvumelana nezinga likazwelonke) insimbi engagqwali, ngeke igqwale. Lokhu kungenxa yokuthi insimbi engagqwali iqukethe into ebalulekile yokuhlanganisa i-Cr (okuqukethwe ngu-Cr ngensimbi engagqwali kufanele kube ngaphezu kuka-13%, ngaphandle kwalokho ukumelana kwayo nokugqwala akunakuqinisekiswa). UCr angakha ifilimu yokungena eminyene ebusweni bensimbi engagqwali ukuvikela insimbi engagqwali ayonakalisi kalula.

Kodwa-ke, ezimweni eziningi, insimbi engagqwali isaqhubeka nokugqwala kwasendaweni ngenxa yomonakalo kwifilimu yokwenziwa ebusweni. Kunezinhlobo eziningi zokugqwala kwendawo, kufaka phakathi i-pitting corrosion, crevice corrosion, intergranular corrosion, corrosion corrosion (lokhu okungenhla kubizwa ngokuthi ukugqwala okuyisihlanu kwendawo yensimbi engagqwali). Phakathi kwazo, okuhlangatshezwana nazo kakhulu (imishini yasendlini, izimboni zokuhlobisa kanye nezetafula) kubhoboza ukugqwala nokugqwala kwemifantu. Izimbangela zalezi zinhlobo ezimbili zokugqwala ziyefana, futhi zombili azinakwehlukaniswa neCl-. Ukukugwema, okokuqala zama ukugwema insimbi engagqwali endaweni yaseCl- isikhathi eside, okwesibili, naka inhlanzeko yendawo yokusetshenziswa kwensimbi engagqwali ukugwema ukungcola, futhi unake nokugwema ukuklwebheka ebusweni bensimbi engagqwali. Ifilimu elisha le-passivation lingahle lakhiwe ebusweni bensimbi engagqwali ngemuva kokuklwebheka, kepha ifilimu esanda kwakhiwa evela ekuklwebhekeni imvamisa intekenteke, futhi imihuzuko kulula ukwakha izikhala zejometri, ezijwayele ukugqwala nokugqwala.

Ngoba kunezinhlobo eziningi zensimbi engagqwali nezinhlobo eziningi zokugqwala, uhlobo ngalunye alufani, ngakho-ke akunakwenzeka ukukhiqiza. Kodwa-ke, uma kufanele unikeze indawo ethambekele ekugqonyeni, nginganikeza iseluleko esisebenzayo kepha hhayi esesayensi nesinzima:

• 1) Uma le ndawo isho indawo enendawo. Ngokuvamile, izindawo ezine-Cl eningi zivame ukugqwala, futhi izindawo ezimanzi zivame ukugqwala. Isibonelo, iShanghai, eduze nolwandle, ine- Cl- eningi, futhi inomswakama kakhulu, ithambekele ekugqweleni.
• 2) Uma kubhekiswa kunoma iyiphi ingxenye yomkhiqizo. Ngokuvamile, ingxenye yokuxhuma yomkhiqizo ithambekele ekugqoleni ngenxa yensika yengxenye yokuxhuma; ingxenye ekhubazekile ivame ukugqwala ngenxa yokushintsha kwesigaba okubangelwe yingcindezi eyinsalela kanye nokusonteka; ingxenye eshiselwe ivame ukugqwala ngenxa yenqubo ye-welding engenangqondo; indawo lapho kugcinwa khona kalula ukungcola nokungcola kulula ukugqwala. Ukugqwala kwenzeka esikhaleni esiphakathi kokushoda komoya-mpilo nokungcola nensimbi engagqwali; indawo eklwebhekileyo igcwele ukugqwala; indawo evamise ukukhiwa futhi ishaywe yizinto ezilukhuni ivame ukugqwala ngenxa yokuguguleka nokugqwala.

3. Iyiphi insimbi engagqwali eyinsimbi enhle kunazo zonke?

Isizathu esenza lo mbuzo uphinde uphakanyiswe njengokungaqondi ngukuthi empeleni, ukubuza lo mbuzo uqobo kunokungaqondi. Okusho ukuthi, kufanele kube khona insimbi engagqwali engcono kakhulu engabhebhethekiswa yinoma yini. Eqinisweni, lo mbono awulungile, okungenani, ngokwazi kwami, ayikho insimbi engenasici ephelele. Uhlobo ngalunye lwensimbi engagqwali lunendawo yalo yokufaka isicelo nenhloso yalo yokuklama. Lapho izinto zithuthukiswa futhi zenzelwe, akunakwenzeka ukulinganisa konke. Izindleko, ukumelana nokugqwala, ukwakha, kanye nokushisela imvamisa kunzima ukulinganisa. Noma sibheka ukumelana nokugqwala kukodwa, akunakwenzeka ukuthi ubheke zonke izinhlobo zokugqwala ekwakhiweni kwezakhi zokukhiqizwa komkhiqizo. Kepha ingakhetha ukugxila kuphela, njengokukhuphula i-Mo ukuze ithuthukise ukumelana nokugqwala kokugqwala, nokwandisa i-Ti ne-Nb ukuze kuthuthukiswe ukumelana nokugqwala kwangaphakathi. Eqinisweni, ngokwahluka kwalezi zingxenye, kunamabanga amaningi wensimbi engagqwali, amaningi angamakhulu. Phakathi kwazo, lezo esihlangabezane nazo kakhulu yilezi ezilandelayo:

• I-304 iyinsimbi engenasici yakudala kakhulu, sihlangabezane nayo kakhulu, i-17% -19% Cr, 8-11% Ni, intengo yamanje yemakethe icishe ibe yi-3-4W / t.
• I-316 iyamelana nokugqwala kwamanzi olwandle. Uma kuqhathaniswa ne-304, i-Mo iyanda, futhi intengo ingaphezulu kwe-6W. I-301 ne-302 inokuqukethwe okuphezulu kwe-C kune-304, kanye nokumelana nokugqwala okuphansi ngokufanayo.
• I-321 Ukungeza i-Ti ne-Nb ukukhulisa i-weldability, ebidume kakhulu e-China phambilini, iye yaphela kancane kancane. Kulinganiselwa ukuthi lezi yizo ohlangane nazo kakhulu.

4. Ungazikhomba kanjani izinhlobo ezahlukene zensimbi engagqwali

Lo mbuzo nawo awuqondwa kahle? okulungile. Ngoba kunzima kuwe ukuhlukanisa phakathi kwezinhlobo ezahlukahlukene zensimbi engagqwali ngeso lenyama. Cishe akunakwenzeka. Ngaphezu kokukwazi ukuhlukanisa nje ukuthi ngeyensimbi engenasici i-austenitic noma ezinye izinhlobo ezisuselwa kuzakhi zayo zikazibuthe, ngisho nochwepheshe wensimbi engagqwali, ngisho nochwepheshe ongumakadebona obesebenza impilo yonke, akakwazi ukuhlukanisa. Kungabonakala kuphela ngemishini ekhethekile. Vele, abantu abakule mboni bangathola umbono onzima ngokususelwa enanini, noma ngabe kukhona uzibuthe, indawo yokukhiqiza, njll., Kepha abasoze bakunikeza impendulo ecacile neqinisekisiwe.

Yiziphi izinhlobo zensimbi engagqwali okufanele zigwenywe uma kungenzeka?

• Insimbi engagqwali eshibhile kakhulu. Yize lesi sitatimende sidlulela ngokweqile, kodwa kunengqondo. Thatha ukuthenga usinki wensimbi engagqwali njengesibonelo. Uma insimbi engagqwali icwila ngamakhilogremu angaphezu kwayi-10 esandleni sakho (akunjalo? Angisazi isisindo sompompi), uma inani lokuthengisa lingaphansi kwama-yuan angama-300, futhi umphathi ekutshele ukuthi akunamandla kazibuthe, isiqiniseko ukuthi insimbi engagqwali. Ngemuva kwalokho, awusoze wathenga. kungani? Angikutshelanga intengo yamanje yemakethe engu-304? . uma ungathengi amakhulu amathani. Kuyi-yuan engama-3 ngekhilogremu (ibiza kangaka, uyazi ukuthi kungani i-hardware yensimbi engagqwali ibiza kangaka?), Ke, izindleko zezinto zokukhanya, amakhilogremu ayi-30 kasinki ovame kakhulu, zizobiza ama-yuan angama-10, kanye nokulahleka, ukucutshungulwa izindleko, ezokuhamba, Izintela, inzuzo ezotholwa ngumphathi, imali yokuphatha, njll., kungenzeka ukuthi uyithenge ngemali engaphansi kwama-yuan angama-300? Ngakho-ke, kunendlela eyodwa kuphela, ukuphinga.
• Musa ukuthenga insimbi engagqwali engu-200. Kusukela ngo-2000, ngenxa yokusebenza kwamandla kazibuthe wabasebenzisi bokudoba, kube nezinsimbi eziningi ezingenasici eziphansi ze-Ni eChina. Babizwa ngama-200 (empeleni, kufanele babizwe ngochungechunge olusha lwama-200). Lezi zinsimbi ezingenazinsimbi ziqukethe i-Ni ephansi kakhulu. Uma okuqukethwe kwe-Ni kuphansi, kuzoba nenkinga. Uma okuqukethwe kwe-Ni kuphansi, insimbi engagqwali izophenduka i-ferrite kalula (izinsimbi ezingenazinsimbi ze-ferritic ziqukethe i-Ni encane noma ayikho), ngakho-ke awukwazi ukusebenzisa uzibuthe wakho. I-Psychology ithuthukisiwe. Ngenxa yalokho, abakhiqizi kufanele bathathe esinye isinyathelo-ukunciphisa okuqukethwe kwe-Cr futhi bandise okuqukethwe kwe-C no-N, ngoba ngale ndlela, isakhiwo se-austenite singatholakala futhi (ubuchwepheshe obuhle, uma ungabuqondi, Akudingeki ukuthi uphenye ukuthi kungani kunjalo., ngingakuchaza kahle lokhu, kepha angicabangi ukuthi kuyadingeka). Kodwa-ke, lokhu kuveze inkinga enkulu kakhulu. Ukumelana nokugqwala kwensimbi engagqwali (okungenzeka kungabi ngokwesayensi kakhulu, kepha ngoba kungashiwo) kuhlobene kakhulu nokuqukethwe kwe-Cr. Ukuphakama kokuqukethwe kwe-Cr, kungcono ukumelana nokugqwala. Ngaphezu kwalokho, i-C% ephezulu nayo izoba nomthelela omubi omkhulu ekumelaneni nokugqwala kwensimbi engagqwali, kuyilapho okuqukethwe kwe-N% kunzima ukukhuphuka (okuphezulu kuzoba ukugcwala kwe-nitrogen, kunjalo, i-N ephezulu iyindlela ebalulekile yokuthuthuka yensimbi engagqwali ), futhi Ukuqina okuphezulu akukuhle. Ngale ndlela, ukumelana nokugqwala kwalolu hlobo lwensimbi engagqwali kuphansi (kuzoba ngcono kakhulu kunensimbi ejwayelekile, kepha kubi kakhulu kunokwedlule 304), kepha ngenxa yokwehla kokuqukethwe kwe-Ni (iningi lolu hlobo lwensimbi engagqwali inokuqukethwe kwe-Ni cishe ngaphansi kwe-1%) Ngakho-ke, izindleko zalolu hlobo lwensimbi engenasici ziphansi kakhulu, futhi intengo yefektri yakudala ingaba cishe yi-1.5w kuphela.
