Kub dov steel phaj hardness yog tsawg, yooj yim ua, ductility yog zoo.Cov ntawv txias dov hardness yog siab, kev ua haujlwm yog qhov nyuaj, tab sis tsis yooj yim rau deformation, siab zog.Kub dov phaj lub zog yog qhov tsawg, qhov zoo yuav luag (tsis tshua muaj oxidation tiav), tab sis zoo plasticity, feem ntau nruab nrab tuab phaj, txias dov phaj: siab zog thiab siab hardness, siab nto tiav, feem ntau nyias phaj, tuaj yeem siv los ua stamping. phaj.Tsis tshua muaj txias kub dov steel phaj, cov khoom siv kho tshuab, tab sis kuj yog qhov ua tsis tau zoo rau kev ua haujlwm forging, tab sis muaj qhov zoo toughness thiab ductility txias-kuav los tiag steel ntawv vim muaj qee qhov kev sib tw hardening, toughness tsawg, tab sis tuaj yeem ncav cuag zoo dua, siv rau txias dabtsi yog khoov caij nplooj ntoos hlav daim thiab qhov chaw, nyob rau tib lub sij hawm vim lub yield point yog ze rau lub tensile lub zog, yog li tsis muaj foresight rau txaus ntshai, nyob rau hauv kev siv cov txheej txheem Thaum lub load tshaj lub load, kev huam yuaj yuav tshwm sim.Kub dov yog dov cov hlau phaj rau hauv cov phaj nyias nyias ntawm qhov kub siab dua.Txias dov yog dov steel phaj ntawm chav tsev kub.Feem ntau, kub dov yog nqa tawm ua ntej, thiab tom qab ntawd txias dov.Thaum lub phaj steel yog tuab, nws tsuas yog kub dov, thiab ces txias dov tom qab nws yog dov rau hauv nyias phaj.Kub dov steel phaj muab faib ua phaj tuab (thickness> 4mm) thiab nyias phaj (thickness 0.35 ~ 4mm).Txias dov steel phaj tsuas yog nyias phaj (thickness ntawm 0.2 ~ 4mm).Qhov ntsuas kub ntawm qhov kub dov feem ntau yog 800 ~ 900 ℃, thiab tom qab ntawd nws feem ntau txias hauv huab cua, yog li lub xeev kub dov yog sib npaug rau normalizing kev kho mob.Cov ntaub ntawv hlau xa tuaj rau hauv lub xeev kub dov yog them nrog ib txheej ntawm oxide zaj duab xis rau ntawm qhov chaw, yog li lawv muaj qee yam corrosion kuj.Cov kev cai rau kev khaws cia, kev thauj mus los thiab kev cia khoom tsis yog nruj raws li cov khoom xa tuaj rau hauv cov duab txias (dov).Piv txwv li, qhov loj thiab nruab nrab-qhov loj me thiab nruab nrab tuab steel phaj tuaj yeem khaws cia rau hauv qhov chaw qhib cov khoom thauj los yog npog nrog rayon.Piv nrog rau kub dov, txias dov hlau cov ntaub ntawv muaj siab dua qhov tseeb, zoo deg zoo, qis nto roughness thiab ntau dua txhua yam khoom.Tab sis nws yooj yim rau corrosion los yog xeb, nws cov ntim, cia thiab kev thauj mus los muaj cov kev cai nruj dua, yuav tsum tau khaws cia rau hauv lub tsev rau khoom, thiab yuav tsum tau xyuam xim rau kev tswj qhov kub thiab av noo hauv lub warehouse.
