Cov kev zam lub log xa mus rau cov khoom ua haujlwm lossis qhov chaw tsis txaus siab uas tau los ntawm forging deformation ntawm hlau blanks. Los ntawm kev thov lub siab mus rau lub ntsej muag hlau kom ua rau yas deformation, nws cov cuab yeej muaj peev xwm hloov tau.
Forging khib kub ua kom kub hnyiab yog txheej txheem txheej txheem kom tau txais cov khoom siv martensite lossis bainite tom qab lub log forging tsim, thaum nws qhov kub siab dua qhov ntsuas kub, nws tau quenched rau hauv qhov nruab nrab quenching tsim nyog.
Tom qab forging pov tseg thaum tshav kub kub quenching thiab tempering, lub log zam tsis tau tsuas yog tau txais cov cuab yeej zoo dua qub, tab sis kuj txuag lub zog, kev yooj yim ntawm cov txheej txheem khiav, luv lub voj voog ntau lawm, txo cov neeg ua haujlwm thiab txuag nqi peev ntawm quenching rauv taws.
Tom qab lub forging ntawm lub log tau quenched thiab kub-kub ntawm qhov kub, lub zog thiab hardness ntawm lub log forging feem ntau siab dua li cov neeg quenching thiab tempering, thiab plasticity thiab toughness yog me ntsis qis dua li cov neeg quenching thiab tempering. (thaum huab cua sov siab zoo li qub). Yog hais tias lub forging khib pov tseg thaum tshav kub kub quenching yog ua tiav, tom qab siv lub siab dua qhov kub thiab txias (feem ntau 40 ~ 80 ° C siab tshaj qhov ntsuas kub ntawm quenching thiab tempering), nws cov yas thiab tawv yog sib npaug los yog siab dua cov ntawm quenching zoo tib yam. Tom qab forging pov tseg thaum tshav kub kub ntawm lub forging ntawm lub log, lub zog thiab hardness yog ho txhim kho nyob rau qhov chaw ntawm tswj plasticity thiab toughness. Tsis tas li ntawd, cov nplej ntawm lub log forging loj dua li ntawm cov quenching zoo tib yam, uas tuaj yeem txhim kho qhov txiav ua tiav ntawm cov khoom siv.
