Dab tsi yog qhov txawv ntawm kub dov steel thiab txias dov hlau?
Kub dov hlau: Kub dov tshwm sim ntawm qhov kub siab tshaj qhov recrystallization ntawm cov khoom, nce qhov kub ntawm cov hlau billet mus rau ntau tshaj 1000 degree ua ntej pub rau hauv lub tshuab dov. Nruam dov tuaj yeem tau txais cov ntawv hlau uas xav tau (3 hli thiab siab dua) lossis cov profiles.
Piv nrog rau txias-kuav los tiag steel, kub-kuav los tiag steel yuav ua tau nyob rau hauv ntau qhov ntau thiab nws cov nqi lag luam tseem nyob rau theem qis. Raws li cov hlau txias rau chav sov, nws hloov cov khoom siv microstructure, ua rau nws cov ductility thiab toughness.
Cold Rolled Steel: Kev ua haujlwm txias yog ib txoj kev tsim hlau uas muaj ntau yam zoo dua li kev ua haujlwm kub. Kev hais lus, kev ua haujlwm txias muaj xws li txias dov thiab kos duab txias. Cov qub yog siv rau kev tsim cov ntawv hlau, thaum lub sijhawm tom kawg tuaj yeem siv rau cov duab plaub thiab puag ncig steel tuav.
Nyob rau hauv sib piv rau kub dov, nyob rau hauv txias dov cov hlau kub yog qis dua nws recrystallization kub. Yog tias siv cov hlau me me, cov hlau tuaj yeem dov mus rau lub thickness ntawm {{0}} 5-3 hli; Yog tias siv cov hlau tsis muaj steel, cov hlau tuaj yeem dov mus rau lub thickness ntawm 0.5-5 hli. Thaum lub sij hawm dov txheej txheem, roj yog siv los ua kom txias cov khoom thiab kuj ua raws li ib tug lubricant. Yog tsis muaj roj zaj duab xis, cov khoom yuav hnav thiab deform. Yog li ntawd, txias dov hlau tuaj yeem txheeb xyuas los ntawm nws cov oiliness thiab du nto. Cov txiaj ntsig tseem ceeb ntawm kev ua haujlwm txias yog: cov khoom tiav tiav qhov loj, du nto, thiab cov khoom muaj zog dua.
