Kwakhona kubalulekile ukukhetha ubushushu bokucima intsimbi yentsimbi yokucima kunye nomgca wonyango wokushisa

Ukuhamba rhoqo izixhobo zokufudumeza ihlala isebenzisa ukucima ukuskena xa indawo yokufudumala yendawo yokusebenza inkulu kwaye unikezelo lwamandla luncinci. Ngeli xesha, indawo yokufudumala ebalwayo A ibhekisela kwindawo ehlanganiswe yi-inductor. Ngoxinaniso lwamandla afanayo, umthombo wamandla ofunekayo uncinci, kwaye iindleko zotyalo-mali zezixhobo ziphantsi, ezilungele ukuveliswa kwebhetshi encinci.

Ukucima ibha yentsimbi kunye nezixhobo zonyango lokufudumala kunomlinganiselo othile wokucima ubushushu bokushisa kwibakala ngalinye lentsimbi. Kuphela ngokufudumeza kunye nokucima ngaphakathi kolu luhlu lweqondo lokushisa kunokufumaneka ulwakhiwo olwanelisayo kunye nokusebenza. Xa izinga lokufudumeza lihlala lihlala, ukuba ubushushu obukhethiweyo bokucima bungaphantsi kobushushu obufanelekileyo, ngenxa yokuba ukuguqulwa kwesigaba akuphelelanga, isakhiwo esishushu yi-austenite kunye ne-ferrite, okanye i-austenite kunye ne-spherite, ukucima Isakhiwo yi-martensite kunye ne-ferrite okanye i-martensite. kunye nepearlite, kwaye ubunzima buya kuncipha. Ukuba ubushushu bokucima ubushushu buphezulu kunobushushu obuphezulu, i-grains eshushu ye-austenite iya kukhula, kwaye umphumo uya kufumaneka emva kokucima. Inaliti ephakathi okanye i-martensite yenaliti eshinyeneyo, ukuba iphezulu intsimbi yekhabhoni, kuya kugcinwa i-austenite, eya kunciphisa ubunzima bomhlaba.

Kwimveliso yokwenyani, ukuba ubushushu obuphezulu bokucima inqanaba elithile lentsimbi luchongiwe, kodwa ngenxa yokuba izinga lokufudumeza (oko kukuthi, amandla athile xa inxalenye ifudunyezwa) likhulu okanye lingaphantsi komlinganiselo wokufudumeza ohambelanayo, awukho ngqiqweni okanye awunqweneleki. ukucima kuya kwenzeka kwakhona Umbutho, ukuba izinga lokufudumeza kwesixhobo sokufudumeza kwe-induction lingaphantsi kwexabiso elihambelanayo lokufudumeza, i-workpiece iya kufudumeza kwiqondo lokushisa elimisiweyo lokucima, kunye nesakhiwo esishushu kakhulu siya kufumaneka emva kokucima. Ukuba ukukhawuleza kukhulu kunomlinganiselo wokufudumala ohambelanayo, i-workpiece iya kutshiswa kwiqondo lokushisa elimiselweyo, emva kokucima Isakhiwo esicinyiweyo kunye nokufudumala okwaneleyo kuya kufumaneka. Ngoko ke, xa ukhetha ubushushu bokucima kwi-bar yensimbi yokucima kunye nomgca wonyango wokushisa, kungekhona nje ukubunjwa kwezinto eziphathekayo kunye nesakhiwo sokuqala kufuneka siqwalaselwe, kodwa impembelelo yesantya sokufudumala kufuneka iqwalaselwe.
