Lub tshuab loj lub cuab yeej casting tu, txaj casting tu yog qhov tseem ceeb ntawm kev saib xyuas ntawm cov casting, lub hom phiaj ntawm kev tu yog ua kom lub casting nto zoo tuaj yeem txhim kho.
Casting melting thiab pouring hlau zoo nyob rau saum npoo zoo ntawm castings yog feem ntau xav txog nyob rau hauv ob yam, ib tug yog cov ntsiab lus ntawm impurities nyob rau hauv dej, tshwj xeeb tshaj yog cov ntsiab lus ntawm hlau oxide, uas yog heev yooj yim los tsim slag los yog slag pores nyob rau saum npoo ntawm cov dej. qhov casting; Qhov thib ob yog cov ntsiab lus roj hauv cov hlau, cov ntsiab lus roj siab yog ib qho yooj yim los ua cov casting hauv qhov chaw los yog subcutaneous pores. Lub ntsiab ntsuas peb coj yuav nce qhov kub ntawm cov hlau, tsim kom muaj qhov zoo tshaj plaws cov tshuaj pleev ib ce, thiab xyuas kom meej tias Cupola yog nyob rau hauv ib txwm mob.
"High kub so, tsis tshua muaj kub pouring" yog tswj cov txheej txheem ntawm pouring, thiaj li yuav txo tau cov casting porosity, shrinkage thiab nto xuab zeb tsis xws luag. Txhim kho qib ntawm kev siv tshuab casting, txhim kho kev xa tawm ntawm cov cuab yeej siv tshuab castings nto zoo
Tsim nyog txiav txim siab qhov chaw seem ntau npaum li qhov ua tau kom txo tau qhov kev sib cais kom txo tau qhov tsim ntawm qhov sib cais ntawm qhov ya ya, nto pob zeb thiab lwm yam khoom nto casting; txhim kho kev ncaj ncees ntawm cov tub ntxhais, txo cov pob qij txha ntawm cov tub ntxhais, txo qhov sib txawv ntawm cov tub ntxhais los yog cov tub ntxhais thiab hom, txhawm rau txhim kho qhov convexity thiab clarity ntawm contour ntawm loj castings.
Kev xaiv cov txheej txheem tsis muaj kev cuam tshuam zoo rau qhov tseeb qhov tseeb thiab contour clarity ntawm casting. Tom qab ntau cov txheej txheem kev xeem, txhua tus txheej txheem parameter yog ua tib zoo xaiv.
Kev siv ntau ntawm cov txheej txheem casting qhov tseeb los txhim kho qib ntawm cov cuab yeej casting kom txo tau qhov tsis xws luag, tshwj xeeb tshaj yog casting defects.
