Ukucisha kuyindlela ebalulekile ekwelapheni ukushisa kwensimbi, okushintsha izakhiwo ezingokomzimba nezomshini zezinto ngokupholisa ngokushesha. Phakathi nenqubo yokucisha, i-workpiece ingena ezigabeni ezinjengokushisa okuphezulu, ukufakwa kwe-insulation, nokupholisa ngokushesha. Lapho i-workpiece ipholiswa ngokushesha ekushiseni okuphezulu, ngenxa yomkhawulo wokuguqulwa kwesigaba esiqinile, i-microstructure ye-workpiece iyashintsha, yakhe izakhiwo zokusanhlamvu ezintsha kanye nokusabalalisa ukucindezeleka ngaphakathi.
Ngemva kokucisha, i-workpiece ngokuvamile isesimweni sokushisa okuphezulu futhi ayikapholi ngokugcwele ekamelweni lokushisa. Kuleli qophelo, ngenxa yomehluko obalulekile wokushisa phakathi kwendawo yokusebenza nendawo ezungezile, i-workpiece izoqhubeka nokudlulisa ukushisa kusuka phezulu kuya ngaphakathi. Le nqubo yokudlulisa ukushisa ingaholela kuma-gradients okushisa wendawo ngaphakathi kwendawo yokusebenza, okusho ukuthi izinga lokushisa ezindaweni ezihlukene ngaphakathi kwendawo yokusebenza akufani.
Ngenxa yokucindezeleka okusele kanye nezinguquko zesakhiwo ezikhiqizwa ngesikhathi senqubo yokucisha, amandla nobulukhuni bomsebenzi wokusebenza kuzothuthukiswa kakhulu. Kodwa-ke, lezi zinguquko zingase futhi zandise ukubola kwe-workpiece futhi zingase zibangele okunye ukukhubazeka kwangaphakathi njengokuqhekeka noma ukubola. Ngakho-ke, kuyadingeka ukwenza ukwelashwa kwe-temering ku-workpiece ukuze kuqedwe ukucindezeleka okusele futhi kufezeke ukusebenza okudingekayo.
I-Tempering iyinqubo yokushisisa i-workpiece ekushiseni okuthile bese uyipholisa, ngenhloso yokuthuthukisa i-microstructure kanye nezakhiwo ezikhiqizwa ngemva kokucisha. Izinga lokushisa elipholile ngokuvamile liphansi kunezinga lokushisa elicishayo, futhi izinga lokushisa elifanele lingakhethwa ngokusekelwe kuzici nezidingo zento. Imvamisa, lapho izinga lokushisa liphakeme kakhulu, kunciphisa ubulukhuni namandla ocezu lokusebenza, kuyilapho ukuqina nokuqina kwepulasitiki kukhuphuka.
Kodwa-ke, uma ucezu lokusebenzela lungakapholi ekamelweni lokushisa, okungukuthi, lusesezingeni lokushisa eliphezulu, ukwelashwa kokushisa akwenzeki. Lokhu kungenxa yokuthi ukufudumala kudinga ukushisisa i-workpiece ezingeni lokushisa elithile futhi uyibambe isikhathi esithile ukuze uzuze umphumela oyifunayo. Uma i-workpiece isivele isezingeni lokushisa eliphezulu, inqubo yokushisa kanye ne-insulation ngeke yenzeke, okuzoholela ekutheni umphumela wokushisa ungahlangabezani nokulindelwe.
Ngakho-ke, ngaphambi kokwenza ukwelashwa kokushisa, kuyadingeka ukuqinisekisa ukuthi i-workpiece ipholile ngokuphelele ekamelweni lokushisa noma eduze negumbi lokushisa. Kungale ndlela kuphela lapho ukwelashwa okuphumelelayo kokushisa kungenziwa ukuze kulungiswe ukusebenza kwe-workpiece futhi kuqedwe amaphutha nokucindezeleka okukhiqizwa ngesikhathi senqubo yokucisha.
Ngamafuphi, uma i-workpiece ecishiwe ingapholiswanga ekamelweni lokushisa, ngeke ikwazi ukubhekana nokwelashwa okushisayo. Ukushisa kudinga ukushisa i-workpiece ekushiseni okuthile nokuyigcina isikhathi esithile, futhi uma umsebenzi usuvele usezingeni eliphezulu lokushisa, inqubo yokushisa ayikwazi ukuqaliswa ngokuphumelelayo. Ngakho-ke, kubaluleke kakhulu ukuqinisekisa ukuthi i-workpiece ipholile ngokugcwele ekamelweni lokushisa ngaphambi kokushisa ngesikhathi senqubo yokwelashwa kokushisa ukuze kuqinisekiswe ukuthi i-workpiece ingafinyelela ukusebenza okudingekayo kanye nekhwalithi.
