Yintoni ukucima i-High-frequency Quenching?

High-frequency quenchingisetyenziswa ikakhulu ukucima umphezulu iindawo zentsimbi zoshishino.Luhlobo lwendlela yonyango yobushushu besinyithi eyenza umphezulu womsebenzi uvelise umsinga othile owenziweyo, ngokukhawuleza ubushushu bomphezulu wamalungu, kwaye ngokukhawuleza ukucima izixhobo zokufudumeza. izixhobo.

Umgaqo wokufudumeza ngokungenisa:Isixhobo sokusebenza sifakwe emoyeni kunye nombhobho wobhedu ovulekileyo kwinzwa, emva kokufikelela kumaza omoya aphakathi okanye amaza ombane aphezulu atshintshatshintshayo (ac), abunjwe kumphezulu kunye nobuninzi bomsinga owenziweyo, umphezulu womsebenzi. okanye ukufudumeza okukhawulezileyo kwendawo (imizuzwana embalwa ukuya kumaqondo obushushu angama-800 ~ 1000 ℃, undoqo usekufutshane nobushushu begumbi) ngoko nangoko emva kwemizuzwana embalwa ngokukhawuleza ukutshiza (dipha) ukupholisa kwamanzi (okanye ukutshiza ukuntywiliselwa kwe-oyile ukupholisa) ukugqiba umsebenzi womlilo wokuntywiliselwa. umphezulu womsebenzi okanye wendawo ukufezekisa iimfuno ezihambelana nobulukhuni.

Xa kuthelekiswa nokucinywa kokufudumeza okuqhelekileyo, ine:

1. Isantya sokufudumeza sikhawuleza kakhulu, esinokwandisa uluhlu lweqondo lokushisa lomzimba we-A kunye nokunciphisa ixesha lokutshintsha.

2. I-cryptocrystalline martensite entle kakhulu inokufumaneka kumphezulu we-workpiece emva kokucima, kwaye ukuqina kuphezulu kancinane (2 ~ 3HRC) .I-brittleness ephantsi kunye namandla aphezulu okudinwa.

3. I-workpiece ephathwayo yinkqubo ayilula i-oxidize kunye ne-decarbonize, kwaye kunye nenye i-workpiece inokuhlanganiswa ngokuthe ngqo kwaye isetyenziswe emva kokucubungula.

I-4, umaleko wokuqina unzulu, kulula ukulawula ukusebenza, kulula ukuyiqonda i-mechanization, i-automation.

5, idangatye umphezulu ukufudumeza ukucima

Ukucinywa kwamatyeli aphezulu kusetyenziswa kwisixhobo sokusebenza esifuna ukuthwala isenzo sokutshintshana komthwalo onjenge-torsion kunye nokugoba.Ifuna umaleko womphezulu ukuba uthwale uxinzelelo oluphezulu okanye ukuxhathisa ukunxiba kunondoqo, kwaye umphezulu we-workpiece kufuneka uqiniswe.Ifanelekile kwintsimbi enomxholo wekhabhoni Thina = 0.40 ~ 0.50%.
