Ductile hlau xuab zeb casting yog ib tug precision manufacturing txheej txheem uas tsim high-zog, complex hlau Cheebtsam los ntawm pouring molten ductile hlau rau hauv xuab zeb pwm. Txoj kev no sib txuas cov castability ntawm grey hlau nrog cov neeg kho tshuab lub zog thiab ductility ntawm hlau, ua rau nws zoo tagnrho rau kev siv tseem ceeb xws li hydraulic systems, twj tso kua mis vaj tse, thiab engineering tsheb qhov chaw. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., peb tshwj xeeb hauv OEM thiab kev cai ductile hlau kev daws teeb meem, kev koom ua ke siab tshaj xuab zeb casting nrog CNC machining kom xa cov khoom uas ua tau raws li cov qauv nruj thiab kev ua tau zoo rau kev lag luam thoob ntiaj teb.
Dab tsi yog Ductile Iron Sand Casting?
Ductile hlau, tseem hu ua nodular cam khwb cia hlau los yog spheroidal graphite hlau, yog ib hom cam khwb cia hlau qhov twg cov graphite qauv tsim raws li spherical nodules es tsis flakes. Qhov sib txawv microstructural no yog ua tiav los ntawm kev ntxiv me me ntawm magnesium los yog cerium thaum lub sij hawm melting txheej txheem. Cov khoom ua tau zoo tshaj plaws tensile zog, cuam tshuam tsis kam, thiab qaug zog durability piv rau cov tsoos grey hlau.
Xuab zeb casting tseem yog cov khoom siv ntau yam thiab siv dav siv los ua cov khoom siv hlau. Cov txheej txheem cuam tshuam nrog kev tsim pwm los ntawm silica xuab zeb sib txuas nrog av nplaum lossis tshuaj resins. Molten hlau yog nchuav rau hauv cov pwm no, qhov twg nws solidifies rau hauv cov duab uas xav tau. Thaum txias lawm, cov xuab zeb pwm tau tawg, nthuav tawm cov ntxhib casting, uas tom qab ntawd ua kom huv, kho cua sov, thiab kev ua kom zoo.
Qhov kev sib xyaw ua ke ntawm cov khoom siv thiab kev tsim ua kom yooj yim tso cai rau cov kws ua haujlwm tsim cov geometries nyuaj uas yuav nyuaj lossis raug txwv tsis pub tsim los siv forging lossis vuam. Rau kev lag luam uas xav tau cov khoom siv muaj zog nyob rau hauv kev kub siab lossis kev ua haujlwm hnyav, cov hlau hlau xuab zeb casting muab qhov kev pom zoo ntawm kev ua tau zoo thiab kev ua haujlwm zoo.
