Casting steel casting system yam ntxwv Cam khwb cia steel yam ntxwv ntawm siab melting point, Hlau Casting tsis zoo mus, shrinkage, yooj yim oxidation, cov yuav tsum tau ntawm cov hlau ua kua ceev thiab du filling.
Lub pouring system muaj cov yam ntxwv hauv qab no: ⑴. Cast steel lub cev shrinkage, casting yooj yim los tsim shrinkage, shrinkage, tawg thiab deformation tsis xws luag. Steel Casting Thick thiab tuab phab ntsa thickness ntawm cov castings nrog lub hauv paus ntsiab lus ntawm kev taw qhia solidification teeb tsa lub riser system, cov kua ntws los ntawm riser rau hauv kab noj hniav, ntxiv dag zog rau lub riser ntawm lub peev xwm filling; kom yooj yim los tsim cov kab nrib pleb, deformation ntawm lub plhaub castings, Cov neeg khiav dej num sab hauv yuav tsum tau muab faib rau hauv cov phab ntsa nyias ntawm cov casting thiab txo cov neeg kho tshuab kev cuam tshuam ntawm tus khiav mus rau lub casting.
Cam khwb cia hlau casting kub yog siab, yooj yim rau oxidize, feem ntau yog siv pob ntawv to. Cov txiaj ntsig zoo ntawm lub hnab ntim slag yog qhov zoo, cov txheej txheem pouring slag nyhuv tsis siab, Steel Casting yog li cov txheej txheem pouring cross -sectional cheeb tsam yog loj qhib, tsis xav tau siab slag muaj nuj nqi, tab sis yuav tsum ceev thiab du tag nrho cov pwm. Nthuav lub pouring siab, Steel Casting yooj yim rau rushing khiav, yog li ntawd, lub casting system yuav tsum siv zog rau cov qauv yooj yim, muaj zog tej yam kuj. Loj thiab nruab nrab castings ntawm sprue thiab steel ntws ntau tshaj 1T ntawm tus khiav thiab khiav, yuav tsum muaj li ntawm refractory cib. Me me cam khwb cia hlau casting system yuav siv tau dej iav, Hlau Casting resin xuab zeb los yog tag nrho cov kev siv ntawm cov xuab zeb muaj pes tsawg leeg, thiab kom muaj zog txaus.
Casting nyob rau hauv cov txheej txheem ntau lawm feem ntau tshwm sim nyob rau hauv ntau yam ntawm casting defects, Steel Casting yuav ua li cas los tiv thaiv cov tsis xws luag, casting manufacturers tau txhawj txog qhov teeb meem. Kab lus no feem ntau qhia txog qee qhov kev nkag siab thiab kev ua haujlwm hauv daim teb no.
Nyob rau hauv lub sij hawm ntev - ntau lawm, pom tias lub ntsiab cam khwb cia hlau casting tsis xws luag, trachoma, nplaum xuab zeb, pores, qhov, xuab zeb caws pliav, o cov xuab zeb, thiab lwm yam, lub ntsiab ntau lawm ntawm cov thawj ntub xuab zeb casting txheej txheem.
Nyob rau hauv lub casting, nto los yog nyob ze ntawm qhov chaw, Steel Casting muaj ntau qhov sib txawv ntawm cov qhov du, cov duab ntawm ib puag ncig, ntev thiab tsis sib xws, muaj ib leeg, tab sis kuj sib sau ua ke. Cov xim yog dawb los yog nrog ib txheej tsaus nti, qee zaum npog nrog ib txheej ntawm oxide. Vim muaj qhov sib txawv thiab ua rau muaj roj, qhov tshwm sim ntawm stomata kuj sib txawv, nrog cov porosity invasive, nag lossis daus porosity thiab reactive stomata.
Invasive porosity loj dua, Steel Casting zoo li cov pear-zoo li tus, feem ntau tshwm nyob rau hauv lub Upper ib feem ntawm lub casting nyob ze ntawm lub core phab ntsa los yog pouring txoj hauj lwm, feem ntau yog vim cov xuab zeb core gas generated nyob rau hauv cov hlau tsis tuaj yeem khiav, pear-zoo li lub qhov me me Txoj hauj lwm qhia tau hais tias cov roj nkag mus rau hauv cov cam khwb cia cov tswv cuab los ntawm qhov ntawd.
Cov nag lossis daus nkig thiab tawg, feem ntau nyob rau hauv qhov chaw casting, feem ntau tib lub cub tawg casting yuav luag txhua qhov tshwm sim, feem ntau yog vim cov hlau hauv cov txheej txheem melting ntawm kev nqus ntawm cov pa ua ntej lub solidification ua tsis tau tejyam rau tag nrho cov nag lossis daus, Hlau Casting nyob rau hauv lub casting los ua ntau tawg me me pores.
Cov pores reactive yog vim cov tshuaj tiv thaiv ntawm cov hlau - mus rau - pwm interface, uas yog hu ua subcutaneous stomata vim lawv cov yam ntxwv faib thiab feem ntau tshwm sim ntawm 1-3 hli hauv qab ntawm daim tawv nqaij ntawm casting (qee zaum nyob rau hauv ib txheej ntawm nplai). Thiab vim hais tias cov pores yog feem ntau elongated pinholes, Hlau Casting qhov ntev axis thiab casting nto perpendicular, tab sis kuj hu ua pinholes.
