Thawj yog tus tsim craftsmanship ntawm tooj liab castings.
Thaum tsim, ntxiv rau kev txiav txim siab txog geometry thiab qhov loj ntawm qhov chaw raws li kev ua haujlwm thiab cov khoom siv hlau, qhov kev tsim nyog ntawm tus tsim yuav tsum tau txiav txim siab los ntawm kev xav ntawm casting alloy thiab casting txheej txheem cov yam ntxwv, uas yog, pom tseeb qhov loj me. thiab solidification thiab shrinkage. , kev ntxhov siab thiab lwm yam teeb meem kom zam lossis txo qhov tshwm sim ntawm qhov tsis xws luag xws li kev sib cais sib cais, deformation, thiab tawg ntawm tooj liab castings.
Tooj liab castings
Qhov thib ob, yuav tsum muaj cov cuab yeej tsim nyog casting.
Ntawd yog, raws li cov qauv, qhov hnyav thiab qhov loj ntawm tooj liab castings, casting alloy yam ntxwv thiab cov yam ntxwv ntawm kev tsim khoom, xaiv qhov tsim nyog parting nto thiab cov duab, core ua txoj kev, thiab tsim nyog tsim cov tuav, txias hlau, risers thiab gating systems. Los xyuas kom zoo castings.
Qhov thib peb yog qhov zoo ntawm raw cov ntaub ntawv siv rau casting.
Qhov zoo ntawm cov nqi hlau, cov ntaub ntawv refractory, fuels, fluxes, modifiers, casting xuab zeb, molding xuab zeb binders, coatings thiab lwm yam ntaub ntawv yog substandard, uas yuav ua rau tsis xws luag xws li pores, pinholes, slag inclusions, thiab xuab zeb sticking nyob rau hauv castings. zoo li tooj liab castings. Kev ua tau zoo thiab sab hauv zoo, hauv cov xwm txheej hnyav, cov castings yuav raug muab pov tseg.
Qhov thib plaub yog cov txheej txheem ua haujlwm.
Nws yog ib qho tsim nyog los tsim cov txheej txheem kev ua haujlwm tsim nyog, txhim kho cov txheej txheem kev ua haujlwm ntawm cov neeg ua haujlwm, thiab xyuas kom meej tias cov txheej txheem txheej txheem raug coj los siv.
