Inkqubo yonyango lobushushu lombhobho wentsimbi ikakhulu ibandakanya ezi ndidi zilandelayo ze-5:

1, ukucima + ubushushu obuphezulu bobushushu (ekwabizwa ngokuba kukucima kunye nokuthoba)

Umbhobho yentsimbi ifudunyezwe ubushushu ukucima, ukuze ulwakhiwo lwangaphakathi umbhobho yentsimbi iguqulwe ibe austenite, kwaye emva koko lupholile ngokukhawuleza ngaphezu isantya ebalulekileyo ukucima, ukuze ulwakhiwo lwangaphakathi umbhobho yentsimbi iguqulwe ibe martensite, kwaye ke ubushushu nobushushu obuphezulu, ekugqibeleni, isakhiwo umbhobho yentsimbi iguqulwa ibe yiyunifomu enomsindo sopranite. ukuqina kombhobho wentsimbi.

2, ukuqheleka (ekwabizwa ngokuba yinto eqhelekileyo)

Emva kokufudumeza umbhobho wensimbi kwiqondo lokushisa eliqhelekileyo, isakhiwo sangaphakathi sombhobho wentsimbi siguqulwa ngokupheleleyo sibe yisakhiwo se-austenite, kwaye ke inkqubo yonyango yokufudumala ipholile ngomoya njenge-medium.After normalizing, izakhiwo zetsimbi ezahlukeneyo zinokufumaneka, ezifana ne-pearlite, i-bainite, i-martensite, okanye umxube wabo.Le nkqubo ayikwazi ukucokisa kuphela ukutya okuziinkozo, ukubunjwa okufanayo, ukuphelisa uxinzelelo lwentsimbi kunye nokuphucula umbhobho onzima.

Ukulinganisa + ukuthoba

Umbhobho wentsimbi ufudunyezwa kwiqondo lokushisa eliqhelekileyo, ukwenzela ukuba isakhiwo sangaphakathi sombhobho wensimbi siguqulwe ngokupheleleyo sibe yisakhiwo se-austenite, kwaye emva koko sipholile emoyeni, kwaye emva koko siphelile. ubunzima.

4, ukuhlamba

Yinkqubo yonyango lobushushu apho ityhubhu yentsimbi ifudunyezwa kwiqondo lobushushu lokucoca kwaye igcinwe kangangexesha elithile, ize ipholiswe phantsi kwiqondo lobushushu elithile ngesithando somlilo. Nciphisa ubulukhuni bentsimbi yombhobho, uphucule iplastiki yayo, ukuququzelela ukucutshungulwa okulandelayo okanye ukuguqulwa okubandayo; Lungisa okuziinkozo, uphelise iziphene ze-microstructure, ulungelelwaniso lolwakhiwo lwangaphakathi olufanayo kunye nokwakheka kombhobho, ukuthintela uxinzeleko lombhobho wentsimbi; ukuguqulwa okanye ukuqhekeka.

5. Unyango lwesisombululo

Ityhubhu yentsimbi ifudunyezwe kwiqondo lobushushu isisombululo, ukuze i-carbides kunye nezinto ezixutywayo zinyibilike ngokupheleleyo kwaye ngokufanayo zinyibilike kwi-austenite, kwaye ke ityhubhu yentsimbi ipholile ngokukhawuleza, ukuze ikhabhoni kunye nezinto ezixutywayo zingabi naxesha lokuxinana, kwaye inkqubo yonyango lobushushu lwesakhiwo esisodwa se-austenite ifunyenwe. ukusetyenzwa koguqulo;Buyisela ukuxhathisa umhlwa kwentsimbi engatyiwayo.
