Thaum ib tug hais Alloy 4 nyob rau hauv ib lub tsev lag luam lossis lub khw muag khoom, koj feem ntau tau txais ib qho ntawm ob qhov kev tshwm sim: kev paub txog ntawm ob txhais tes qub, lossis saib tsis meej pem los ntawm cov neeg uas xav tias nws tsuas yog lwm yam tsis zoo. Nws tsis yog. Hauv kuv peb lub xyoos dhau los nyob ib ncig ntawm lub plhaub pwm thiab CNC txaj, kuv tau pom cov khoom no tau txais pigeonholed, underutilized, thiab qee zaum cem rau qhov ua tsis tiav uas yog cov txheej txheem tiag tiag. Nws tsis yog ib qho txuj ci tseem ceeb, tab sis nws qhov kev sib npaug tshwj xeeb ua rau nws nyob ntsiag to, txhim khu kev qha rau cov khoom siv uas yuav tsum tau tiv thaiv qee yam kev tsim txom - thermal cycling, nruab nrab corrosion, thiab kev ntxhov siab tsis tu ncua - tsis muaj tus nqi ntawm superalloy. Qhov tsis meej pem pib nrog lub npe nws tus kheej; nws tsis yog tus qauv tsim qauv zoo li 316 lossis 17-4PH, uas ua rau muaj ntau qhov kev xav, thiab cov kev xav tau kim.
Kev muaj tiag nyob rau hauv Foundry Floor
Ntawm peb qhov chaw, uas tau hloov mus rau Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), peb tau khiav Alloy 4 los ntawm ob qho tib si peev thiab plhaub pwm casting txheej txheem ntau zaus tshaj qhov kuv suav tau. Thawj qhov koj kawm yog tias nws qhov fluidity yog qhov zoo, tsis zoo. Nws tsis nchuav zoo li qee qhov ntawm cov pa roj carbon monoxide ntau dua, yog li koj yuav tsum tau ua tib zoo nrog koj lub rooj vag thiab riser tsim, tshwj xeeb tshaj yog rau cov phab ntsa nyias. Yog tias koj kho nws zoo li tus qauv cam khwb cia hlau, koj yuav xaus nrog mistruns lossis porosity ntau dhau. Peb tau kawm qhov no txoj kev nyuaj ntawm kev txiav txim ntxov rau cov khoom siv ntawm lub valve. Cov ntawv luam tawm hu rau txoj hauv kev nyuaj, thiab peb siv peb cov txheej txheem steel gating layout. Cov txiaj ntsig tau txaus ntshai - tej zaum 60%. Cov khib nyiab khib nyiab tag nrho ntawm cov khoom tsis tiav. Nws tsis yog qhov ua txhaum ntawm alloy; nws yog peb li tsis hloov cov txheej txheem rau cov khoom siv.
Qhov twg Alloy 4 tiag tiag pib qhia nws tus cwj pwm yog post-cast. Nws machinability zaum nyob rau hauv qhov nthuav nruab nrab hauv av. Nws tsis yog npau suav phem zoo li qee cov npib tsib xee, tab sis nws kuj tsis zoo li buttery li cov hlau lead. Koj xav tau kev teeb tsa nruj thiab cov cuab yeej ntse. Peb pom tau hais tias siv ib tug me ntsis ntau zoo rake thiab kom ntseeg tau zoo heev coolant xa ntawm lub txiav ntug drastic txhim kho lub neej thiab nto tiav ntawm peb CNC machining chaw.
