Kev tshuaj xyuas qhov zoo thiab qhov tsis zoo ntawm stainless hlau precision casting txheej txheem:
Cov phooj ywg hauv kev lag luam casting paub tias cov khoom siv ntawm stainless hlau precision casting yog siab dua li ntawm cov hlau cam khwb cia, tab sis nws qhov kev ua tau zoo tshaj plaws ntawm cov hlau cam khwb cia. Nws yog hu ua peev casting lossis precision casting. Nws cov ntsiab lus melting yog qhov siab, thiab cov kua hlau yog ib qho yooj yim rau oxidize, lub fluidity ntawm molten hlau tsis zoo thiab lub shrinkage loj. Nyob rau hauv qhov tseeb, los ntawm cov tswv yim taw tes ntawm view, lub casting ntawm stainless hlau precision yeeb nkab tsis yog tsuas yog haum rau lub casting ntawm ntau yam thiab alloys.
Tom ntej no, Xiaobian yuav piav qhia txog qhov zoo thiab qhov tsis zoo ntawm stainless hlau precision casting txheej txheem rau koj: ua ntej, vim qhov tsis zoo ntawm cov kua hlau tsis zoo, txhawm rau tiv thaiv cov rwb thaiv tsev txias thiab tsis txaus ntawm cov hlau castings, phab ntsa tuab ntawm cov hlau tsis tuaj yeem ua tsis tau. tsawg dua 8mm; Cov qauv ntawm lub rooj vag system yuav tsum yooj yim thiab cov ntu loj yuav tsum loj dua li cov hlau cam khwb cia; Cov pwm qhuav lossis pwm kub yuav tsum tau txais yuav; Ua kom qhov kub thiab txias, feem ntau yog 1520 ° ~ 1600 ℃, vim tias qhov kub thiab txias yog siab, superheat ntawm molten steel yog loj, cov kua tuav lub sij hawm ntev, thiab fluidity tuaj yeem txhim kho.
Txawm li cas los xij, qhov kub siab dhau lawm yuav ua rau muaj qhov tsis xws luag xws li coarse grain, kub tawg, porosity thiab xuab zeb nplaum. Yog li ntawd, lub pouring kub ntawm me me, nyias-walled thiab complex castings yog hais txog lub melting point kub ntawm steel + 150 ℃; Lub pouring kub ntawm loj thiab tuab phab ntsa castings yog hais txog 100 ℃ siab tshaj nws melting point.
Txhawm rau tiv thaiv qhov tshwm sim ntawm shrinkage kab noj hniav thiab kab nrib pleb nyob rau hauv stainless hlau precision castings, peb yuav tsum tau siv cov kev ntsuas no kom nws cov phab ntsa thickness uniform thiab tsis txhob ntse ces kaum thiab txoj cai kaum. Tsis tas li ntawd, sawdust yuav tsum tau ntxiv rau hauv pwm rau casting, coke yuav tsum tau ntxiv rau hauv cov tub ntxhais, thiab thaum kawg hollow core thiab roj xuab zeb core yuav tsum tau siv los hloov cov concession thiab huab cua permeability ntawm xuab zeb pwm los yog core. Tsuav peb ua raws li qhov uas Xiaobian tau hais, peb tuaj yeem ua tiav qhov kev xav tau.
