Umehluko omkhulu phakathi kwe-annealing kanye nokujwayelekile:

1. Izinga lokupholisa lokujwayelekile lishesha kancane kunalelo lokupholisa, futhi izinga lokupholisa okukhulu likhulu.
2. Isakhiwo esitholwe ngemva kokujwayelekile silungile, futhi amandla nobulukhuni buphakeme kunobu-annealing.

Ukukhethwa kwe-annealing kanye nokujwayelekile:

1. Emapayipini ensimbi engenamthungo ekhabhoni ephansi anokuqukethwe kwekhabhoni engaphansi kuka-0.25%, ukujwayelekile kusetshenziswa esikhundleni sokudonsa. Ngenxa yokuthi izinga lokupholisa elisheshayo lingavimbela ipayipi lensimbi engenamthungo ekhabhoni ephansi ekutholeni usimende wamahhala wemfundo ephakeme emngceleni wokusanhlamvu, ngaleyo ndlela kuthuthukiswe ukusebenza kokuguga okubandayo kwezingxenye zokugxiviza; i-normalization ingathuthukisa ubulukhuni bensimbi kanye nokusebenza kokusika kwepayipi eliphansi le-carbon seamless steel. ; Uma ingekho enye inqubo yokwelapha ukushisa, ukujwayela kungacwenga okusanhlamvu futhi kuthuthukise amandla amapayipi ensimbi engenamthungo ekhabhoni ephansi.

2. Ipayipi lensimbi engenamthungo elikhabhoni elikhabhoni eliphakathi nendawo elinokuqukethwe kwekhabhoni phakathi kuka-0.25% no-0.5% nalo lingenziwa libe lijwayelekile esikhundleni sokudonsa. Nakuba i-medium-carbon steel ebandayo ipayipi yensimbi engenamthungo enokuqukethwe kwekhabhoni eseduze nomkhawulo ophezulu inobunzima obuphezulu ngemva kokujwayelekile, isengasikwa, futhi izindleko ezijwayelekile ziphansi futhi ukukhiqiza kuphezulu.

3. Amapayipi ensimbi adonswa ngokubanda angenamthungo anokuqukethwe kwekhabhoni phakathi kuka-0.5 no-0.75%, ngenxa yokuqukethwe okuphezulu kwekhabhoni, ubulukhuni ngemuva kokujwayelekile buphezulu kakhulu kunobokucwiliswa, futhi kunzima ukwenza ukucutshungulwa kokusika, ngakho-ke ukucwiliswa okuphelele ngokuvamile esetshenziselwa ukunciphisa Ukuqina kanye nokusebenza okuthuthukisiwe.

4. Ikhabhoni ephezulu noma insimbi yamathuluzi enokuqukethwe kwekhabhoni > 0.75% wepayipi lensimbi engenamthungo elidonsayo elidonsayo ngokuvamile lithatha i-spheroidizing annealing njengokwelashwa kokushisa kokuqala. Uma kukhona usimende wesibili onemeshed, kufanele ube ojwayelekile kuqala. I-Annealing inqubo yokwelapha ukushisa lapho ipayipi lensimbi engenamthungo elidonsa ukubanda lishisiswe libe izinga lokushisa elifanele, ligcinwe isikhathi esithile, bese lipholiswa kancane. Ukupholisa kancane kuyisici esiyinhloko se-annealing. Amapayipi ensimbi angenamthungo adonswe ngokubanda adonswe nge-anneal ngokuvamile apholiswa abe ngaphansi kuka-550 ℃ ngesithando somlilo kanye nokupholiswa komoya. I-Anealing iyindlela yokwelapha yokushisa esetshenziswa kakhulu. Enqubweni yokukhiqiza amathuluzi, isikhunta noma izingxenye zemishini, njll., kuvame ukuhlelwa njengokwelashwa kokushisa kokuqala ngemuva kokubunjwa, ukubumba nokushisela, nangaphambi kokusika (okubi) ukucubungula ukuze kuqedwe ezinye zezinkinga ezibangelwa inqubo yangaphambilini. amaphutha, futhi ulungiselele imisebenzi elandelayo.

Inhloso Yokuhlanganisa:

①Thuthukisa noma uqedele ukukhubazeka okuhlukahlukene kwesakhiwo kanye nengcindezi eyinsalela ebangelwa insimbi ngesikhathi sokubunjwa, ukubumba, ukugingqika nokushisela, futhi uvimbele ukuwohloka nokuqhekeka kwendawo yokusebenza;
② thambisa umsebenzi wokusika;
③ Cwenga okusanhlamvu futhi uthuthukise isakhiwo ukuze uthuthukise izakhiwo zemishini ye-workpiece;
④ Lungiselela inhlangano ukwelashwa kokushisa kokugcina (ukucisha, ukuthambisa).
