Unyango lobushushu bomphezulu lubhekiselele kwinkqubo yokunyanga ubushushu kuphela umaleko ongaphezulu wentsimbi. Unyango lobushushu bomhlaba lunokufumana ubume bemetallographic obufunekayo kunye neempawu zomatshini.
Iindlela zonyango oluqhelekileyo olusetyenziswa kumphezulu wobushushu zezi: induction ukufudumeza quenching, idangatye ukufudumeza quenching, laser unyango ubushushu, contact ukumelana ukufudumeza quenching, electrolyte quenching, ipulse ukufudumeza unyango ubushushu, njl. Ngokusebenzisa unyango ubushushu phezu komhlaba, castings kunye nezinye iindawo zentsimbi banokufumana umaleko womphezulu. ehlangabezana neemfuno zokusebenza.
Emva kokuba umaleko wokuqina womphezulu ufunyenwe ngokufudumeza komphezulu kunye nokucima, undoqo wokuphosa usenakho ukugcina i-microstructure yasekuqaleni kunye nokusebenza, ukuze kufezekiswe ukusebenza okugqwesileyo okubanzi kokuphucula amandla okudinwa, ukuphucula ukumelana nokunxiba kunye nokugcina ukuqina. Ngexesha elifanayo, unyango lobushushu bomhlaba lunokunciphisa ukusetyenziswa kwamandla kwaye kwangaxeshanye lunciphise ukucima i-deformation.
Ukuqiniswa kwe-induction yinkqubo yonyango lobushushu esebenzisa isiphumo sobushushu esiveliswa yi-induction current ngokusebenzisa i-workpiece ukutshisa umphezulu wokuphosa, kwindawo okanye ngokubanzi, kwaye emva koko wenze ukupholisa ngokukhawuleza. Imigaqo esisiseko yokufudumeza kwe-induction yile: i-electromagnetic induction, isiphumo solusu kunye nokuqhuba ubushushu.
Iimpawu zokucinywa koMfudumalo:
I-1) Ukucima i-induction ine-superplasticity. Ubunzima bomphezulu we-workpiece yi-2-3 HRC ephezulu kunokucima okuqhelekileyo. Emva kokufudumeza kwe-induction kunye nokucima, i-martensite ye-casting incinci kwaye i-carbides iyahlakazeka.
I-2) Ukuxhatshazwa kokugqoka ukuphosa emva kokucima ukushisa kwe-induction kuphezulu kunokucima okuqhelekileyo.
3) Ngenxa yokuba umphezulu we-workpiece ulungile i-cryptocrystalline martensite kwaye kukho uxinzelelo olucinezelayo, amandla okudinwa kwe-workpiece aphuculwe kakhulu.
4) Umgangatho we-workpiece uzinzile kwaye i-deformation incinci.
5) Isantya sokufudumala ngokukhawuleza kunye nokusebenza kakuhle kwe-thermal
6) Imveliso ephezulu, kulula ukuyiqonda imveliso eyenziwe ngoomatshini
