Yog li yuav ua li cas koj tiv thaiv cov khoom ntawm quenching kev nyuaj siab thaum lub sij hawm
txheem precision pwm puagtxias?
Lub tempering yuav tsum tau siv los tshem tawm kev ntxhov siab, thiab tom qab quenching ntawm tus qauv qauv, boil 30 ~ 60min ua ntej txias kev kho mob, tshem tawm 15% mus rau 25% quenching kev nyuaj siab, stabilizing residual aus, ces nqa tawm - 60 ° C pa cua txias kev kho mob los yog sib sib zog nqus txias. kev kho mob ntawm -120 ° C.
Qhov qis dua qhov kub, qhov ntau qhov seem ntawm austenite hloov pauv yog tus naj npawb ntawm martensite, tab sis nws tsis tuaj yeem hloov pauv. Cov txiaj ntsig kev sim qhia tau hais tias qhov seem ntawm austenite suav txog kwv yees li 2% mus rau 5%, thiab qhov me me ntawm cov austenite seem tuaj yeem ua rau muaj kev ntxhov siab thiab tsis muaj zog. Txij li cov residual austenite yog mos thiab tawv, nws tuaj yeem nqus tau lub zog ntawm lub zog ntawm lub zog nrawm, tshem tawm cov theem hloov kev ntxhov siab. Tom qab kev kho mob khaub thuas, tus qauv qauv raug coj tawm hauv dej kub kom sov qhov kub, thiab 40% -60% kev kho mob txias tuaj yeem tshem tawm. Thaum qhov kub nce mus rau hauv chav tsev kub, nws yuav tsum tau tempered nyob rau hauv lub sij hawm mus ntxiv tshem tawm cov kev kho mob khaub thuas kev nyuaj siab, tsis txhob sib sau ua mob khaub thuas kab mob, tau txais cov ntaub so ntswg ruaj khov thiab kev ua tau zoo, xyuas kom meej tias
txheem precision pwm puag tsis deformable thaum khaws cia thiab siv.
