Unyango lobushushu lusetyenziselwa ukuguqula ipropathi ebonakalayo yeimixokelelwane yentsimbi engqukuva, ngokuqhelekileyo ukwandisa amandla kunye neempawu zokunxiba zekhonkco elijikelezayo lokuhambisa ikhonkco ngelixa ugcina ukuqina okwaneleyo kunye ne-ductility yesicelo. Ukunyanga ukushisa kubandakanya ukusetyenziswa kokufudumeza, ukupholisa ngokukhawuleza (ukucima), kwaye ngamanye amaxesha kunye nokupholisa amacandelo kumaqondo okushisa aphezulu ukufumana umphumo oyifunayo.
Zonke iintsimbi zibandakanya uhlobo oluthile lwe-microstructure. Iimolekyuli zitshintsha indawo xa zishushu. Xa isinyithi sicinywa, iimolekyuli zihlala kwi-microstructure entsha, kunye namanqanaba obunzima obuninzi kunye nokulindela amandla kunye nokuxhatshazwa kokugqoka kwecandelo. Amacandelo ekhonkco aphathwa ngokutshisa ngokwahlukileyo ngaphambi kokuhlanganisana, okunceda ukubeka ipropati ekujoliswe kuyo yecandelo ngalinye kwimeko efanelekileyo. Zininzi iindlela ezahlukeneyo zonyango lobushushu ezingasetyenziselwa ukulungisa amanqanaba obulukhuni kunye nobunzulu. Ezona ndlela zintathu zixhaphakileyo zonyango lobushushu kumacandelo ekhonkco zezi:
Ngokuqiniswa
Ngokuqiniswa yinkqubo yokufudumeza, ukucima kunye nokuthoba amakhonkco ekhonkco elijikelezayo. Le nkqubo iqinisa kwaye yomeleza izinto ngokulinganayo kulo lonke icandelo lamakhonkco ekhonkco, ngokungafaniyo nezinye iindlela eziqinisa kuphela umaleko wangaphandle. Isiphumo yintsimbi epholileyo eqinile kwaye yomelele, kodwa isenayo i-ductility eyaneleyo kunye nokuqina.
Carburizing - Ukuqina kwetyala
I-Carburizing yinkqubo yokubeka intsimbi kwikhabhoni ukuze iqine ngelixa isinyithi sifudunyezwa. Ukongeza ikhabhoni kumphezulu wentsimbi kutshintsha ukwakheka kweekhemikhali ukwenza ukuba iphendule ngakumbi kunyango lobushushu ngelixa igcina ukuqina okuthambileyo, okubambekayo. Ikhabhoni ifunxwa kuphela kwindawo evezisiweyo yekhonkco lekhonkco, kwaye ubunzulu bokungena kwekhabhoni bulingana nexesha elichithwe ezikweni, kungoko kubizwa ngokuba bukuqina kwetyala. Ukuqina kwetyala kwenza ukubakho kweentsimbi eziqinileyo kunezinye iindlela zokuqina, kodwa ukuqina kwetyala elinzulu kunokuthatha ixesha elininzi kwaye kubiza kakhulu.
Ukwenziwa lukhuni
Ngokufana nokuqina, kufuna inkqubo yokufudumeza kwaye emva koko kucinywe, kodwa ukusetyenziswa kobushushu kuqhutyelwa ngendlela elawulwayo ngokusebenzisa inkqubo yokungeniswa (intsimi yamagnetic enamandla). Ukuqina kwe-induction ngokuqhelekileyo kuqhutyelwa njengenkqubo yesibini ukongeza ngokuqina. Inkqubo yokungenisa ulawulo iyanciphisa ubunzulu kunye nepateni yokutshintsha kobulukhuni. Ukuqina kwe-induction kusetyenziselwa ukwenza lukhuni icandelo elithile lenxalenye, kunokuba inxalenye yonke.
Ngelixa unyango lobushushu yindlela esebenzayo kunye nebalulekileyo yokuphucula umgangatho wekhonkco elijikelezayo, ukuvelisa umgangatho ophezulu, amakhonkco okuhambisa ixesha elide afuna ezinye iinkqubo ezininzi zokuvelisa ezifana nokugoba kunye ne-welding.
