Kudzima, kunonziwo kuomesa ndiyo nzira yekudziya uyezve kutonhora kwesimbi (kana imwe alloy) nekumhanya kwakanyanya kuti kune kuwedzera kwakanyanya mukuoma, kungave kuri pamusoro kana kwese.Panyaya yevacuum Quenching, iyi nzira inoitwa muvacuum furnaces umo tembiricha dzinosvika 1,300°C dzinogona kusvikwa.Nzira dzekudzima dzichasiyana maererano nezvinhu zvinorapwa asi kudzima gasi uchishandisa nitrogen kunonyanya kuwanda.
Kudzima Gasi:
Munguva yevacuum gasi Kudzima, zvinhu zvinopiswa mukushaikwa kweokisijeni neconvection mukati meiyo inert gasi (N₂) uye / kana kupisa mwaranzi mukudzvinyirira.Simbi inoomeswa nerukova rwenitrogen, uko kutonhora kunogona kutariswa nekusarudza yakawandisa kudzvanywa.Zvichienderana neiyo workpiece chimiro zvinokwanisika zvakare kusarudza kutungamira uye nguva yekuvhuvhuta nitrogen.Optimization yenguva uye simbi tembiricha kutonga kunoitwa panguva yekushanda pamwe nekushandiswa kwepilot thermocouples iyo inogona kuiswa pane workpiece mukamuri yekudziya.Simbi inobatiswa kupisa muchoto chevacuum inowana iyo yakatsanangurwa zvimiro zvesimba uye kuoma mukati mese muchinjiko-chikamu, pasina pamusoro decarburization.Austenitic zviyo zvakanaka uye zvinoenderana nemitemo yenyika.
Zvinenge zvese zvemasimbi aloyi anonakidza, akadai sesimbi dzechitubu, simbi dzinotonhora, simbi dzakadzima uye dzakadzikama, simbi dzinodzivirira kukwesha, simbi dzinopisa dzinoshanda uye simbi dzemidziyo, pamwe nenhamba huru yesimbi isina tsvina uye yakakandwa. -iron alloys, inogona kuomeswa nenzira iyi.
Vacuum Oiri Kudzima
Vacuum Oil quenching inotonhodza zvinhu zvinopisa neVacuum oil.Sezvo kuendeswa kwechaji kuri kuitika pasi pevacuum kana inert-gasi kudzivirirwa mushure mekunge tatsvaira kuchenesa choto, chikamu chepamusoro chinogara chakachengetedzwa kusvikira chanyudzwa zvachose mumafuta.Kudzivirirwa kwepamusoro kwakafanana zvakanyanya kungave kudzima mumafuta kana gasi.
Mukana wakakura uchienzaniswa neyakajairwa mumhepo-kudzima oiri mhinduro ndiko kunyatso kudzora kwema paramita ekutonhodza.Nechoto chevacuum, zvinokwanisika kugadzirisa akajairwa quenching paramita - tembiricha uye kushushikana - uye kugadzirisa zvakare kudzvanywa pamusoro petangi rekudzima.
Kugadzirisa kudzvanywa kuri pamusoro petangi kunounza mutsauko mukumanikidza mukati mebhati remafuta, izvo zvinoshandura curve yekutonhora kwemafuta inotsanangurwa pamhepo yemhepo.Chokwadi, nzvimbo yekubikira ndiyo nhanho panguva iyo kumhanya kwekutonhora kwakanyanya.Iko kushanduka kwemafuta ekumanikidza kuchagadzirisa vaporization yayo nekuda kwekupisa kwemutoro.
Kudzikiswa kwekumanikidzwa kunomutsa iyo vaporization phenomena, iyo inotanga nhanho yekubikira.Izvi zvichawedzera kutonhodza kwemvura yekudzima uye kunatsiridza simba rekuomesa maringe nemamiriro emuchadenga.Nekudaro, chizvarwa chakakura cheutsi chinogona kukonzera sheath phenomenon uye chinokonzera deformation.
Kuwedzera kwekumanikidzwa mumafuta kunodzivisa kuumbwa kwemhute uye kudzoreredza kubuda.Iyo sheath inonamatira kune chikamu uye inotonhorera pasi zvakanyanya kufanana asi zvishoma zvakanyanya.Kudzima oiri muvacuum saka kwakawedzera yunifomu uye kunokanganisa kushomeka.
Vacuum mvura inodzima
Maitiro senge vacuum mafuta ekudzima,Ndiyo mhinduro yakanakira kuomesa kupisa kurapwa kwealuminium, titanium kana zvimwe zvinhu zvinoda kutonhodzwa nekukurumidza zvakaringana.
