Qhov zoo thiab cov yam ntxwv ntawm centrifugally cam khwb cia tooj liab
Centrifugal castings kuj feem ntau hu ua "kua forgings" vim hais tias thaum lub sij hawm centrifugal txheej txheem, cov hlau molten yog forged los ntawm lub siab compressive siab exerted los ntawm centrifugal quab yuam.
Lub cev muaj zog xws li tensile, creep thiab qaug zog yog txhim kho los ntawm 30% piv rau static thiab peev casting txoj kev.
Centrifugally cam khwb cia hlau purity tuaj yeem tiv taus ntau dua thiab cov kab mob tsis muaj kev tawg.
Ntau txhiab tus stencils muaj los tshem tawm cov nuj nqis ntawm kev yuav khoom, khaws cia, tswj thiab pov hwm cov qauv.
Cua pores, porosity thiab inclusions raug tshem tawm ua ntej ua tiav.
Lub sij hawm machining kim tsis yog nkim rau qhov tsis xws luag thiab cov khoom pov tseg tau txo qis.
Cov txheej txheem centrifugal casting muab kev lag luam ntawm ntau qhov ntau thiab tsawg, duab thiab ntau.
Cov nyhuv "molecular accumulation" yog ib qho tseem ceeb feature qhia los ntawm high-speed centrifugal casting txheej txheem:
Vim tias cov ntu no tau tsim kom muaj kev ntxhov siab ntau zaus lub ntiajteb txawj nqus, lawv nthuav tawm cov qauv denser, cov qauv hloov kho lub cev.
Thaum lub sij hawm spinning, cov hlau hnyav dua raug yuam tawm sab nraud, tshem tawm cov oxides thiab impurities thiab ua rau lawv "ntub" sab hauv mus rau hauv nruab nrab axis rau kev tshem tawm hauv kev ua haujlwm tho txawv tom qab.
Tsis zoo li ib txwm lub ntiajteb txawj nqus lossis zoo li qub castings, uas yog txias los ntawm sab hauv thiab sab nrauv, centrifugal castings khov los ntawm sab nrauv sab hauv. Qhov tshwm sim yog ib feem dawb ntawm shrinkage kab noj hniav, cua hnab ris thiab pores.
Muaj peev xwm ntau lawm:
Bronze centrifugal castings yog muaj rau feem ntau tooj liab alloys. Sab nraud txoj kab uas hla mus txog 3,150 mm (124 nti). Peb centrifugally cam khwb cia bronze raj cov khoom tau ntawv pov thawj machined rau qhov pom zoo ua tiav nyiaj pub dawb.
