Iikhonsepthi ezininzi eziqhelekileyo zonyango lobushushu

1. Ukulungelelanisa:
Inkqubo yokushisa ukushisa apho intsimbi okanye iinxalenye zetsimbi zifudumala kwiqondo lokushisa elifanelekileyo ngaphezu kwendawo ebalulekileyo ye-AC3 okanye i-ACM, igcinwe ixesha elithile, kwaye ipholile emoyeni ukuze ifumane isakhiwo esifana ne-pearlite.

2. Ukudibanisa:
Inkqubo yonyango lobushushu apho i-hypoeutectoid workpieces yentsimbi ifudunyezwa ukuya kutsho kwi-20-40 degrees ngaphezu kwe-AC3, igcinwe ishushu kangangexesha elithile, ize ipholiswe kancinane eziko (okanye ingcwatywe esantini okanye ipholiswe kwikalika) ukuya kutsho ngaphantsi kwama-500 degrees emazikweni. umoya.

3. Unyango oluqinileyo lwesisombululo sobushushu:
Inkqubo yonyango lobushushu apho i-alloy ifudunyezwa kwiqondo lokushisa eliphezulu kwaye igcinwe kwiqondo lokushisa rhoqo kummandla wesigaba esisodwa ukutshabalalisa ngokupheleleyo isigaba esigqithisiweyo kwisisombululo esiqinileyo, kwaye sipholile ngokukhawuleza ukuze sifumane isisombululo esiqinileyo se-supersaturated.

4. Ukuguga:
Emva kokuba i-alloy ifumene isisombululo esiluqilima sonyango okanye i-deformation yeplastiki ebandayo, iipropati zayo zitshintsha ngexesha xa ibekwe kwiqondo lokushisa okanye ngaphezu kweqondo lokushisa.

5. Unyango lwesisombululo esiluqilima:
Ukunyibilikisa ngokupheleleyo izigaba ezahlukeneyo kwi-alloy, ukomeleza isisombululo esiqinileyo kwaye uphucule ukuqina kunye nokumelana nomhlwa, ukuphelisa uxinzelelo kunye nokuthambisa, ukuze uqhubeke nokusebenza kunye nokwenza.

6. Unyango lokwaluphala:
Ukufudumeza nokubamba kwiqondo lokushisa apho isigaba sokuqinisa sinciphisa, ukwenzela ukuba isigaba sokuqinisa siqhube kwaye siqine, siphucule amandla.

7. Ukucima:
Inkqubo yonyango lobushushu apho intsimbi iqinisekiswa khona kwaye emva koko ipholile ngesantya esifanelekileyo sokupholisa ukwenzela ukuba i-workpiece ihambe inguqu yesakhiwo engazinzanga njenge-martensite kuzo zonke okanye ngaphakathi koluhlu oluthile lwecandelo lomnqamlezo.

8. Ukufudumeza:
Inkqubo yonyango lobushushu apho i-workpiece ecinyiweyo ifudunyezwa kwiqondo lokushisa elifanelekileyo elingaphantsi kwendawo ebalulekileyo ye-AC1 kwixesha elithile, kwaye ipholile ngokusebenzisa indlela ehlangabezana neemfuno zokufumana isakhiwo esifunekayo kunye neempawu.

9. Carbonitriding yentsimbi:
I-Carbonitriding yinkqubo yokungeniswa kwekhabhoni kunye ne-nitrogen ngaxeshanye kwinqanaba lentsimbi. Ngokwesiko, i-carbonitriding ikwabizwa ngokuba yi-cyanidation. Okwangoku, i-carbonitriding yegesi ephakathi kunye ne-low-temperature gas carbonitriding (okt, i-gesi soft nitriding) isetyenziswa ngokubanzi. Injongo ephambili yobushushu obuphakathi kwegesi carbonitriding kukuphucula ukuqina, ukunyamezela ukunxiba kunye namandla okukhathala kwentsimbi. I-carbonitriding yegesi ephantsi yobushushu ininzi i-nitriding, kwaye injongo yayo ephambili kukuphucula ukunyanzeliswa kokunxiba kunye nokuxhathisa ukubanjwa kwentsimbi.

10. Ukucima kunye nokuthoba:
Ngokuqhelekileyo kuyinto yesiko ukudibanisa ukucima kunye nobushushu obuphezulu njengonyango lobushushu olubizwa ngokuba ngukucima kunye nokuvutha. Ukucima kunye nonyango lokufudumala lusetyenziswa ngokubanzi kwiindawo ezahlukeneyo ezibalulekileyo zesakhiwo, ngakumbi ezo zidibanisa iintonga, iibholithi, iigiya kunye neeshafti ezisebenza phantsi kwemithwalo etshintshanayo. Emva kokucinywa kunye nokunyangwa kwonyango, isakhiwo se-sorbite esivuthayo sifunyenwe, kwaye iimpawu zayo zomatshini zingcono kunezo zakhiwo eziqhelekileyo ze-sorbite ezinobunzima obufanayo. Ukuqina kwayo kuxhomekeke kwiqondo lobushushu eliphakamileyo lobushushu kwaye lihambelana nokuzinza kwentsimbi kunye nobungakanani becandelo lomnqamlezo lomsebenzi, ngokubanzi phakathi kwe-HB200-350.

11. Ukutshisa:
Inkqubo yonyango lobushushu esebenzisa imathiriyeli yokubrawuza ukudibanisa izinto ezimbini zokusebenza kunye.
