Umahluko omkhulu phakathi kwe-annealing kunye ne-normalizing:

1. Izinga lokupholisa lokupholisa okuqhelekileyo likhawuleza kancinci kunelo lokupholisa, kwaye inqanaba lokupholisa okukhulu likhulu.
2. Ulwakhiwo olufunyenwe emva kokuqhelekileyo lulungile, kwaye amandla kunye nobunzima buphezulu kunoko-annealing.

Ukhetho lwe-annealing kunye nokuqhelekileyo:

1. Kwimibhobho yensimbi ephantsi ye-carbon enomthungo enomxholo wekhabhoni engaphantsi kwe-0.25%, i-normalization idla ngokusetyenziswa endaweni yokuqhawula. Ngenxa yokuba isantya sokupholisa esikhawulezayo sinokuthintela umbhobho wentsimbi ophantsi wekhabhoni ongenamthungo ekuwisweni kwesamente yasimahla ephezulu kumda weenkozo, ngaloo ndlela uphucula ukusebenza kogutyulo olubandayo lweendawo zokungqisha; i-normalization inokuphucula ubulukhuni bentsimbi kunye nokusebenza kokusika kombhobho wensimbi ophantsi wekhabhoni. ; Xa ingekho enye inkqubo yonyango lobushushu, i-normalization inokucoca iinkozo kunye nokuphucula amandla emibhobho yentsimbi ephantsi yekhabhoni.

2. Umbhobho wensimbi ongenamthungo wekhabhoni otsalwa yikhabhoni kunye nomxholo wekhabhoni ophakathi kwe-0.25% kunye ne-0.5% nawo unokumiselwa njengesiqhelo endaweni yokufunxa. Nangona i-medium-carbon steel ebandayo-intsimbi engenamthungo umbhobho wentsimbi kunye nomxholo wekhabhoni kufuphi nomda ophezulu unobunzima obuphezulu emva kokuqhelekileyo, kusekho Inokunqunyulwa, kwaye ixabiso eliqhelekileyo liphantsi kwaye imveliso iphezulu.

3. Imibhobho yentsimbi engenamthungo epholileyo enomthungo enomxholo wekhabhoni phakathi kwe-0.5 kunye ne-0.75%, ngenxa yomxholo wekhabhoni ephezulu, ukuqina emva kokuqhelekileyo kuphezulu kakhulu kunoko, kwaye kunzima ukwenza ukucutshungulwa kokusika, ngoko ke i-annealing epheleleyo. ngokuqhelekileyo isetyenziselwa ukunciphisa Ubulukhuni kunye nokuphuculwa kobuchule.

4. Ikhabhoni ephezulu okanye isixhobo sentsimbi esinomxholo wekhabhoni> 0.75% wombhobho wentsimbi ongenamthungo otsalwa ngokubanda ngokuqhelekileyo uthatha i-spheroidizing annealing njengonyango lokuqala lobushushu. Ukuba kukho i-meshed yesibini ye-cementite, kufuneka ibe yinto eqhelekileyo kuqala. Ukufakwa kwe-Anealing yinkqubo yonyango lobushushu apho umbhobho wentsimbi ongenamthungo otsalwayo ufudunyezwa kubushushu obufanelekileyo, ugcinwe ixesha elithile, uze upholiswe kancinane. Ukupholisa okucothayo lolona phawu luphambili lwe-annealing. Imibhobho yentsimbi epholileyo etsalwa ngokubanda engenamthungo ipholiswa ngokubanzi ibe ngaphantsi kwama-550 ℃ ngeziko kunye nokupholiswa ngumoya. I-Anealing lunyango lobushushu olusetyenziswa ngokubanzi. Kwinkqubo yokwenziwa kwezixhobo, isikhunta okanye iinxalenye zemishini, njl., ngokuqhelekileyo icwangciswa njengonyango lokuqala lobushushu emva kokuphosa, ukubunjwa kunye ne-welding, nangaphambi kokusika (ngokukrakra) ukucutshungulwa kokuphelisa ezinye zeengxaki ezibangelwa yinkqubo yangaphambili. iziphene, kwaye ulungiselele imisebenzi elandelayo.

Injongo yokuHlola:

① Ukuphucula okanye ukuphelisa iziphene ezahlukeneyo zesakhiwo kunye noxinzelelo olushiyekileyo olubangelwa yintsimbi kwinkqubo yokuphosa, ukubumba, ukuqengqeleka kunye ne-welding, kwaye uthintele ukuguqulwa kunye nokuqhekeka kwendawo yokusebenza;
② thambisa icwecwe lokusika;
③ Cokisa iinkozo kwaye uphucule ubume ukuphucula iimpawu zoomatshini bomsebenzi;
④ Lungiselela umbutho kunyango lokugqibela lobushushu (ukucima, ukuthambisa).
