Kev kho mob kub hnyiab thiab lub cev muaj hlau

Kev kho cua sov kev kho kom haum: quenching 870 ℃ ± 20 ℃, roj txias; tempering 480 ℃ ± 50 ℃ (tshwj xeeb xav tau, 30 ℃).

Crystal qauv: tempered tus.

Kev Nyab Xeeb: Cov kub kub kub rau kub los yog cov khoom kub tsis yog cua sov, muab cov cua txias sib tw los rhaub cov tshuaj.

Txoj kev kho cua sov

60Si2Mn kev kho kom sov yog kev sib sib zog nqus thiab sib quas zawg, kub kub quenching thiab kub kub, deformation cov txheej txheem kho kub. Cov txheej txheem tuaj yeem txhim kho lub zog thiab kev ua haujlwm ntawm 60Si2Mn caij nplooj ntoos hlav steel. 60Si2Mn belongs rau lub caij nplooj ntoos hlav steel, tsim los ua vaj tsev nplooj ntawv caij nplooj ntoos hlav. 60Si2Mn caij nplooj ntoos hlav steel cua sov kev kho mob yog kev sib sib zog nqus thiab ntsuas quenching, sub kub quenching thiab kub kub tempering, deformation kho cov txheej txheem kho kub. Cov txheej txheem tuaj yeem txhim kho lub zog thiab kev ua haujlwm ntawm 60Si2Mn caij nplooj ntoos hlav steel.

Kev kho mob kub txheej txheem

Spheroidizing kev nplaum: kev siv ntawm 850 degrees cua sov, roj quenching, luv luv tshuab isothermal pob tshuab (790 degrees cua sov 25Min, quenching rau 680 degrees rwb thaiv tsev 1H, cua txias rau 500 degrees baked), yuav tau txais qhov zoo tshaj plaws spheroidal lub koom haum. 60Si2Mn steel quenching kub feem ntau siv 850 degrees ~ 870 degrees, roj txias. Tempering kub li ntawm cov kev xav tau ntawm cov pwm, xws li 400 degrees tempering, hardness 46HRC; 500 degree tempering, hardness 40HRC; 600 degree tempering, hardness 34HRC. Nyob rau hauv 150 ~ 160 degrees ntawm kev ua kom kub zoo kom tau qhov zoo tshaj plaws haum, yuav tsum saib xyuas kom zoo txog 300 degrees tempering brittle cheeb tsam. Yuav tsum muaj qhov muaj zog dua ntawm lub pwm, uas yuav tsum muaj kev ruaj ntseg zoo ntawm qhov ntsuas, kub kub tau nce mus txog 250 degrees, qhov hardness ntawm 55 ~ 60HRC, tau zoo dua toughness. A230 ~ 860C-cua txias-HBS303 quenching; 870C-roj-thiab-dej txias-HBS≤220, Ar3 = 700, Ar3 = 770, Ms-300 mus rau 305, HRC> 61 Hardness tom qab tempering ntawm txawv txias HRC: 150C-61,200C-60,300C-56,400C-51,500 C-43,550C-38,600C-33,650C-29 Cov kub kub 430 ~ 480C, dej los yog cua, HRC45 ~ 50 Cov nram qab no yog qhov ntsuas ntawm kev kho cua kub ntawm cov yas hlau nplooj hlav lub caij nplooj ntoos hlav quenching thiab cua sov sijhawm thiab thickness: mm / min , 6.5 / 2,8 / 3,8.5-10 / 4,12 / 5 tempering tuav lub sij hawm Thiab thickness: mm / min, <10 25-30,="" 10-15="" 30-35,="" 15-20="" 40-45="" ,="" 20-25="">
