Yog vim li cas yog lub nto hardness ntawm cov khoom siv ntau zaus steel tom qab induction quenching siab tshaj qhov zoo tib yam quenching?

Cov khoom siv high-frequency quenching Lub hardness ntawm steel qhov chaw tom qab induction quenching yog siab dua li ntawm qhov zoo tib yam quenching vim hais tias lub hardness ntawm steel qhov chaw tom qab induction quenching yog siab tshaj qhov zoo tib yam quenching, uas yog tus yam ntxwv ntawm steel induction quenching, thiab yog qee zaum hu ua superhard phenomenon. Muaj ntau yam kev piav qhia rau nws cov txheej txheem: ib qho kev piav qhia yog tias lub sijhawm cua sov induction yog luv luv thiab cov xwm txheej rau kev loj hlob ntawm austenite nplej tsis muaj, ua rau cov nplej nplua nuj ntawm quenched steel; Lwm qhov kev piav qhia yog tias qhov txias ceev ntawm induction quenching yog qhov siab heev, , muaj qhov loj residual compressive kev nyuaj siab nyob rau hauv quenched nto txheej. Yog li ntawd, qhov saum npoo hardness zoo dua.

Lub square steel quenched los ntawm high-frequency quenching khoom raug txiav, thiab piv nrog rau hardness ua ntej txiav, hardness tom qab txiav yog txo los ntawm ntau tshaj 2HRC nyob rau hauv nruab nrab, uas ua pov thawj hais tias lub hardness yuav txo tom qab lub residual compressive kev nyuaj siab raug tshem tawm. Lwm qhov kev sib cav uas tuaj yeem piav qhia txog qhov nce ntawm qhov tawv tawv los ntawm qhov seem ntawm qhov kev ntxhov siab yog qhov nyuaj ntawm induction hardened steel txo ntau dua li qhov qub quenching thaum nws yog tempered ntawm qhov kub thiab txias.
