Ukuze kuthuthukiswe ubulukhuni obungaphezulu nokugqoka ukumelanaipayipi elingunxande, ingacutshungulwa enye indawo, okungukuthi ingaphezulu lelangabi lomlilo, ukuphakama, ukuqina kwemvamisa ephakathi nendawo kanye nokwelashwa ngamakhemikhali nokunye okunjalo.Imvamisa, ukuqina kwendawo ephakathi nendawo ephakathi nendawo enkulu, kushisiswe ezingeni lokushisa elingu-850-950.℃.Njengoba kunikezwe ukungahambi kahle kwayo okushisayo, ngakho-ke ijubane lokushisa alisheshi kakhulu, ngaphandle kwalokho lizoncibilika ngokukhubazeka okuthile okucisha imifantu.Izidingo zokuqina kokungeniswa kokungeniswa kwe-Rectangular Pipe normalizing matrix inhlangano ngokuyinhloko yi-pearlite.Ukupholisa amanzi okufutha noma isixazululo esinamanzi se-polyvinyl alcohol, izinga lokushisa elishisayo ebangeni lama-200-400.℃, ubulukhuni 40-50HRC, ubulukhuni nokumelana nokugqoka ukuqinisekisa ubuso bePipe Rectangular.
Ukwelashwa kokushisa kwepayipi elingunxande nakho kunezinzuzo ezintathu ezilandelayo:
(A) Ukuzinza okuphezulu kwe-dimensional yepayipi elinemba elingunxande, elidinga ukunemba okuphezulu, kufanele ligcine ukuqina kohlangothi, ngenxa yalokho isikole siqonde emoyeni, izinga lokupholisa lihamba kancane, ngakho-ke indima ye-austenite uzinzile izonyusa inani eligciniwe. austenite izicubu ipayipi elingunxande, kufanele kube ukwelashwa okubandayo;
(B) Nciphisa ukuhlanekezela okucisha ngenxa yesikwele esinwetshiwe kanye neshubhu elingunxande, inqubo eqinile ikhubazeka kalula, kufanele ilawulwe ngokuqinile, ukwelashwa kokushisa kuyisinyathelo esibalulekile ekucimeni, ukusetshenziswa kwepulasitiki kube ukuguquguquka kwe-austenite okufika ngesikhathi, okuyisinyathelo esibalulekile. isinyathelo esibalulekile sokuqinisekisa izinga labo lokuvumelana, okufanele kube ukucisha okugeza okushisa okushisayo noma ukulungiswa kokushisa okupholisayo okuhlongozwayo isikhathi esithile ngenkathi ukushisisa kufanele kulengiswa ekushiseni, ukunciphisa ukuwohloka kokuqina emafutheni, ngomzila wesitimela onembayo, ukunciphisa ukuwohloka. i-nitriding yegesi noma i-plasma nitriding, njll;
(C) Ukuqina okuphezulu kwesikwele esikhulu kanye neshubhu elingunxande limelana nemithwalo yokukhathala, kufanele libe nobulukhuni obuphezulu, ngakho-ke kufanele libe ukuqina, noma ukuqina noma ukwelashwa kwamakhemikhali, kulandelwe inqubo yokuthambisa.
