Insimbi ye-X12 MF iyinsimbi yensimbi ehlanganisiwe, okwakhiwa kwayo okuyinto enquma izici zayo ezinhle kakhulu zobuchwepheshe. Lo mkhiqizo uzibonakalise kahle kokubili ekukhiqizeni amathuluzi omndeni kanye nezingxenye ezigxotshiwe ekukwakheni umshini nakwezinye izimboni. Ngezinzuzo nezindleko zensimbi ye-X12 MF ngemimese kuyokwaziswa kule ngqungquthela.
Izimpawu zemimese kusuka ensimbi Х12МФ
Noma iyiphi insimbi iyinsimbi yensimbi ne-carbon, kodwa isilinganiso sabo sephesenti, kanye nokuba khona kwezinye izingxenye, kunquma izindawo zomkhiqizo ophelile. Lokhu kuhlukahluka kukhiqizwa nge-welding ephindaphindiwe, futhi le alloy ihlanganisa vanadium, ithusi, i-silicon, i-manganese, i-molybdenum, i-phosphorus, i-nickel nesulfure. Baqaphela amandla omese wonke wensimbi owenziwe nge-X12MF ensimbi nezinye izinto, ukumelana nokubola, ukuqina nokukwazi ukusika. Ukukhiqizwa kwensimbi eshintshiwe enziwe ngokuhambisana ne-GOST no-TU. Iphelile ngo-950 ° C, enikeza ubunzima bezingxenye ezingu-64 ze-HRC.
Ukwenza kube nzima kakhulu, futhi ukwelashwa okushisa, kuhlanganise nokubeka ukushisa okuqondile, ukuguga, ukushisa kanye nezinye izilinganiso, kuyinkimbinkimbi emangalisayo. Noma kunjalo, kukhona abakhiqizi abakhulu abenza imimese kule nsimbi.
Insimbi yalesi banga yilapho eqala ukukhiqizwa:
- volokov;
- ukudweba amabhodi;
- ukugoba nokudala kufe;
- Ama-eyelets wokulinganiswa kwessimbi esenziwe nge-bar for thread rolling;
- izakhi eziyinkimbinkimbi zezitembu zomzimba.
Emishini kagesi kanye nezinhlelo zamandla kagesi zamapayipi kagesi, izingxenye ezivela kule nsimbi nazo zitholakala, kodwa maduzane kuye kwasetshenziselwa ukwenza imimese, ngokuvamile ukuzingela (okuncane kakhulu okuvakasha ).
I-pluses yilezi:
- Isidingo sokuqala esinikezwe emikhawulweni ubukhali obubukhali, kodwa okhaliphile ithuluzi, ngokushesha kunembile, kodwa lokhu akusebenzi emimese eyenziwe ngensimbi Х12МФ. Ukugxila kwekhabhoni kule alloy kuyinto engu-14.5-16.5%, okuhlinzeka ukwanda kokugqoka nokuphepha kwezingxenye zokusika, kodwa lokhu kunciphisa ukumelana nokushisa, ngakho-ke lo mkhwa awukwazi ukubizwa ngokuthi ungenasici, kodwa futhi nokugqwala "embonweni" wamanzi, njengeDamaseku , ayihlanganisiwe. Ukuze insimbi enjalo ingabi mnyama, idinga ukunakwa kahle.
- Inzuzo enkulu ye-X12MF yensimbi yemimese yukuthi ngisho nangobunzima bezinyunithi ezingama-50 buhlala bukhali ngemva kokusika izinto ezingekho eziyinkulungwane.
- I-Molybdenum ekubunjweni kwayo inikeza i-alloy ukuba ifane futhi ifane, okubaluleke kakhulu ithuluzi lokusika. I-vanadium ithuthukisa ubunzima namandla ensimbi, yandisa ukuhlala kwayo, futhi i-silicon inikeza amandla akhethekile. Phakathi nokuhlolwa okuningi kwafunyanwa ukuthi ngisho nangemva kokuba amathambo amaningi esika, ukuvulwa kwamathini amaningi ensimbi kanye namakhulu ezinsika ze-oak, umsi wommese uhlala ubukhali, ngaphandle kwama-serif futhi ukwazi ngisho nokusika iphephandaba ngaphansi kwesisindo salo.
Umthengi:
- Kodwa zonke lezi zinzuzo ziphikisana ne-single drawback - fragility. Ngakho-ke, imimese enjalo akufanele iphonswe, iphonswe, ihlolwe ukugoba, njll.
- Ngokuvamile imivimbo evela ku-alloy enjalo inezinhlamvu ezincane kanye nesiqondiso sokusika. Zithandwa ngabazingeli baseSiberia naseMpumalanga Ekude, ngoba ezimweni zezulu ezinzima kangaka kubalulekile ukuba ube nommese omuhle nawe. Ekusetshenzisweni okusemandleni nasekuqiniseni ikhwalithi yayo kudlula ikhwalithi yethuluzi lokusika kusuka kwezinye izinhlobo zensimbi. Ngakho-ke, ukufunwa kwabo eminyakeni yamuva, kanye nezinga lokuthengisa, likhulile kakhulu.
