Ukuze kuphuculwe ubulukhuni bomphezulu kunye nokumelana nokunxibaumbhobho woxande, inokulungiswa ngomphezulu othile, oko kukuthi umphezulu welangatye lomlilo elisulungekileyo, phezulu, ukuqina komphezulu ophakathi kwamatyeli aphakathi kunye nonyango oluthile lwekhemikhali nokunye okunjalo.Ngokubanzi, umgangatho ophakathi wokuqina wokuqina kobuninzi, ufudunyezwa kubushushu obuyi-850-950.℃.Ngenxa yokungahambi kakuhle kwe-thermal, ngoko ke isantya sokufudumeza asikhawulezi kakhulu, kungenjalo siya kunyibilika kunye nezinye iziphene ezicima iintanda.Iimfuno zokuqiniswa lukhuni kweRectangular Pipe normalizing matrix umbutho ubukhulu becala yipearlite.Ukupholisa amanzi okutshiza okanye isisombululo esinamanzi sepolyvinyl yotywala, ubushushu bobushushu kuluhlu lwe-200-400℃, ubunzima be-40-50HRC, ubunzima kunye nokumelana nokugqoka ukuqinisekisa ubuso bombhobho weRectangular.

Unyango lobushushu lombhobho woxande lukwanazo ezi nzuzo zintathu zilandelayo:

(A) Uzinzo oluphezulu lwe-dimensional kumbhobho woxande oluchanekileyo, olufuna ukuchaneka okuphezulu, kufuneka lugcine uzinzo lwe-dimensional, ngenxa yoko isikolo sithe ngqo emoyeni, isantya sokupholisa siyacotha, ngoko indima ye-austenite izinzile iya kwandisa inani lokugcinwa. Umbhobho we-austenite tissue rectangular, kufuneka ibe unyango olubandayo;

(B) Nciphisa ukucima ukugqwetheka ngenxa yesikwere kunye ityhubhu yoxande, inkqubo elukhuni ngokulula ikhubazeke, kufuneka ilawulwe ngokungqongqo, unyango lobushushu linyathelo elibalulekileyo kwinkqubo yokucima, ukusetyenziswa kweplastiki ibe yi-supercooled austenite ulungelelwaniso ngexesha elifanelekileyo. Inyathelo eliphambili lokuqinisekisa izinga lokuhambelana kwabo, ekufuneka kucinywe ukuhlamba okushushu okanye ukupholisa ukulungiswa kobushushu kucetywayo ixesha elithile ngelixa ukufudumeza kufuneka kuxhonywe ekufudumezeni, ukunciphisa ukuqina kwe-oyile, umgaqo kaloliwe ochanekileyo, ukunciphisa ukuguqulwa. i-nitriding yegesi okanye i-plasma nitriding, njl.

(C) Ubunzima obuphezulu besikwere kunye netyhubhu enoxande ukumelana nemithwalo yokudinwa, kufuneka ibe nobunzima obuphezulu, kwaye ke ngoko kufuneka ibe lukhuni, okanye iqine okanye unyango lobushushu lwekhemikhali, lulandelwe yinkqubo yokuthambisa.
