Grey Cast Iron Investment Casting

Grey cam khwb cia hlau castings feem ntau yog tsim los ntawm cov xuab zeb casting txheej txheem, txawm li cas los xij, rau qee qhov castings uas xav tau qhov tseeb raug thiab muaj cov qauv tsim,peev casting txheej txheemkuj yog ib qho kev xaiv zoo.

Thaum peb nrum grey hlau, peb nruj me ntsis ua raws li cov tshuaj muaj pes tsawg leeg thiab txhua yam khoom raws li lub stardards los yog yuav tsum tau los ntawm cov neeg muas zaub. Tsis tas li ntawd, peb muaj peev xwm thiab cov khoom siv los kuaj seb puas muaj qhov tsis xws luag hauv cov xuab zeb grey hlau castings.

Txawm hais tias cam khwb cia hlau tuaj yeem muaj qhov feem pua ​​​​ntawm cov pa roj carbon monoxide ntawm 2 txog 6.67, qhov kev txwv tsis pub muaj feem ntau ntawm 2 thiab 4%. Cov no yog cov tseem ceeb vim lawv zoo heev casting zoo. Grey hlau yog pheej yig dua li cov hlau, tab sis nws muaj zog tensile thiab ductility ntau dua li cov hlau. Grey hlau tsis tuaj yeem hloov cov pa roj carbon steel, thaum cov hlau nplaum tuaj yeem hloov cov pa roj carbon steel hauv qee qhov xwm txheej vim muaj lub zog tensile siab, tawm dag zog thiab elongation ntawm cov hlau hlau.

Kev nqis peev (poob ciab) casting yog ib txoj hauv kev ntawm precision casting complex ze-net-puab cov ntsiab lus siv cov qauv ntawm cov qauv siv quav ciab. Kev nqis peev casting lossis poob ciab yog txheej txheem hlau casting uas feem ntau siv cov qauv siv quav ciab puag ncig los ntawm lub plhaub ceramic los ua cov pwm ceramic. Thaum lub plhaub dries, siv quav ciab yog melted tam sim ntawd, tawm tsuas yog cov pwm. Tom qab ntawd cov khoom siv casting yog tsim los ntawm cov hlau molten rau hauv cov pwm ceramic.

Silica sol casting txheej txheem yog lub ntsiab peev casting txheej txheem ntawm RMC peev casting foundry. Peb tau tsim cov thev naus laus zis tshiab ntawm cov khoom siv nplaum kom ua tiav cov khoom siv hluav taws xob ntau dua thiab siv tau zoo los tsim cov slurry plhaub. Nws yog ib qho kev sib tw dhau los uas Silica sol casting txheej txheem hloov cov txheej txheem dej iav tsis zoo, tshwj xeeb tshaj yog rau stainless hlau casting thiab alloy hlau casting. Dhau li ntawm cov khoom siv molding tshiab, silica sol casting txheej txheem kuj tau tsim kho kom ruaj khov thiab tsis tshua muaj cua sov.
