Kubalulekile futhi ukukhetha izinga lokushisa lokucisha lensimbi yokucisha kanye nomugqa wokwelapha we-temering
Imvamisa ephakathi imishini yokushisa yokufakelwa kuvame ukusebenzisa ukucisha ukuskena lapho indawo yokushisa ye-workpiece inkulu futhi ukunikezwa kwamandla kukuncane. Ngalesi sikhathi, indawo yokushisa ebaliwe A ibhekisela endaweni ehlanganiswe yi-inductor. Ngokuminyana kwamandla okufanayo, umthombo wamandla odingekayo mncane, futhi izindleko zokutshala impahla ziphansi, ezifanele ukukhiqizwa kwenqwaba encane.
Ibha yensimbi yokucisha nokokusebenza yokwelapha ukushisa inebanga elithile lokushisa elicishayo lebanga ngalinye lensimbi. Kuphela ngokufudumeza nokucisha ngaphakathi kwalolu banga lokushisa kungatholwa isakhiwo nokusebenza okwanelisayo. Uma izinga lokushisa lihlala njalo, uma izinga lokushisa elikhethiwe lokucisha lingaphansi kwezinga lokushisa elilungile, ngenxa yokuthi ukuguqulwa kwesigaba akuphelele, isakhiwo esishisayo siyi-austenite plus ferrite, noma i-austenite plus spherite, i-quenched Isakhiwo siyi-martensite plus ferrite noma i-martensite plus pearlite, futhi ubulukhuni kuzokwehla. Uma izinga lokushisa lokushisa elicishayo liphakeme kunezinga lokushisa elilungile, izinhlamvu ezishisayo ze-austenite zizokhula, futhi umphumela uzotholakala ngemva kokucisha. Inaliti ephakathi noma i-martensite yenaliti ewugqinsi, uma iphezulu i-carbon steel, izogcinwa i-austenite, ezonciphisa ubulukhuni bobuso.
Ekukhiqizeni kwangempela, uma izinga lokushisa elilungile lokucisha lezinga elithile lensimbi linqunywa, kodwa ngenxa yokuthi izinga lokushisa (okungukuthi, amandla athile lapho ingxenye ishiselwa) likhulu noma lingaphansi kwezinga lokushisa elihambisanayo, alinangqondo noma alifiseleki. ukucima kuzophinde kwenzeke Inhlangano, uma izinga lokushisa lemishini yokushisa yokungeniswa lingaphansi kwezinga lokushisa elihambisanayo, i-workpiece izoshiswa ekushiseni okunqunyiwe kokucisha, futhi isakhiwo esishisayo sizotholakala ngemva kokucima. Uma ukusheshisa kukhulu kunezinga lokushisa elihambisanayo, i-workpiece izoshiswa ekushiseni okunqunyiwe kokucima, ngemva kokucisha Isakhiwo esicinyiwe esinokushisa okwanele sizotholakala. Ngakho-ke, lapho ukhetha izinga lokushisa lokucisha lensimbi yokucisha ibha yensimbi kanye nomugqa wokwelapha wokushisa, akufanele kucatshangelwe kuphela ukwakheka kwezinto ezibonakalayo kanye nesakhiwo sokuqala, kodwa ithonya lejubane lokushisa kufanele licatshangelwe.
