Dab tsi yog qhov sib txawv ntawm DC01 thiab DC03?
DC: Cov khoom txias-cov khoom ntim cov khoom lag luam rau kev txias, qhov twg "d" sawv rau kev kos duab zoo. DC01: Txheem kos duab zoo, zoo tagnrho rau kev siv cov kev siv txias. DC03:: Nqus kev nqus cov khoom zoo, tso cai rau kev tsim muaj ntau dua. DC04, DC05: Tshwj xeeb sib sib zog nqus daim duab zoo rau cov qauv nyuaj.
Dab tsi yog qhov sib txawv ntawm DC04 thiab DC05?
DC04 - Qib qib no yog qhov tsim nyog rau cov kev tsim nyog. DC05 - QUCUCT-TXAUS SIAB-TXAUS SIAB RAU TSIM NYOG RAU GRERD GROUSE YUAV TSUM TAU. DC06 - Qhov kev sib sib sib nqus me me tshwj xeeb yog qhov tsim nyog rau txoj kev xav tau zoo tshaj plaws. DC07 - Qhov kev sib sib zog nqus super-daim duab sib sib zog yog qhov haum rau txoj kev tsim kom muaj.
Dab tsi yog microstructure ntawm DC04 hlau?
Micructure ntawm DC04 Hlau muaj cov ferrite nrog ntshiab segregation shearing kab, uas yog qhov tshwm sim ntawm cov yas deformation thaum lub sij hawm steel coil dov, Daim duab
DC03 qib steel yog dab tsi?
Me-carbon steel rau kev sib tsoo txias
Qib DC03 Cov khoom pov thawj kev sib sib zog nqus ntawm cov duab sib sib zog nqus nyob rau hauv txhua hom kev deformation. Qeb no yog qhov tsim nyog rau kev tsim kev cai xws li sib sib zog nqus thiab muaj kev sib zog.
DC05 khoom siv yog dab tsi?
Qib kawm DC05 yog qhov zoo, ultra-tsawg cov pa roj carbon, sib sib zog nqus hlau. Nws yog feem ntau siv hauv cov ntawv thov uas xav tau superior fircability thiab cov xim zoo.
