Hlau castingstau siv dav hauv kev lag luam thiab tshuab txij li niaj hnub nrhiav tau tsim. Txawm tias nyob rau lub sijhawm tam sim no, cov hlau castings tseem ua lub luag haujlwm tseem ceeb hauv cov tsheb thauj khoom, tsheb thauj mus los, tsheb laij teb, kev tsim kho tshuab, khoom siv hnyav ... thiab lwm yam. Cam khwb cia hlau muaj xws li grey hlau, ductile hlau (nodular), hlau dawb, compacted graphite hlau thiab malleable hlau. 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.
Carbon hlau castingsyog siv nyob rau hauv ntau daim ntawv thov kev lag luam thiab ib puag ncig ib yam nkaus. Nrog rau lawv cov qib ntau, carbon steel tuaj yeem kho cua sov los txhim kho nws cov txiaj ntsig thiab lub zog tensile, hardness lossis ductility rau tus engineer daim ntawv thov xav tau lossis xav tau cov khoom siv kho tshuab. Qee qib qis ntawm cov cam khwb cia hlau tuaj yeem hloov tau los ntawm cov hlau nplaum, tsuav yog lawv lub zog tensile thiab elongation ze txaus. Rau kev sib piv lawv cov khoom siv kho tshuab, peb tuaj yeem xa mus rau cov khoom siv tshwj xeeb ASTM A536 rau cov hlau ductile, thiab ASTM A27 rau carbon steel.

Ductile hlau casting Cheebtsammuaj kev poob siab zoo dua li carbon steel, thaum carbon steel castings muaj qhov zoo dua weldability. Thiab rau qee qhov, cov ductile iorn castings tuaj yeem muaj qee qhov kev ua yeeb yam ntawm kev hnav thiab xeb. Yog li cov hlau nplaum hlau tuaj yeem siv rau qee lub twj tso kua mis lossis cov khoom siv dej. Txawm li cas los xij, peb tseem yuav tsum tau ceev faj tiv thaiv lawv ntawm kev hnav thiab xeb. Yog li feem ntau hais lus, yog tias cov hlau nplaum tuaj yeem ua tau raws li koj qhov yuav tsum tau ua, cov hlau nplaum tuaj yeem yog koj thawj qhov kev xaiv, es tsis txhob carbon steel rau koj cov castings.

Cov txheej txheem steel niaj hnub no tau muab faib ua ob pawg tseem ceeb: kev siv tau thiab tsis siv tau. Nws tau tawg ntxiv los ntawm cov khoom siv pwm, xws li xuab zeb casting, poob ciab casting lossis hlau pwm casting. Raws li ib yam ntawm precision casting txheej txheem, lubpeev castinguas siv cov tshuaj silica thiab dej iav bonded casting los yog lawv daim ntawv cog lus raws li lub plhaub tsev cov ntaub ntawv feem ntau yog siv nyob rau hauv RMC Casting Foundry los tsim carbon steel castings. Txawv precision casting txheej txheem kuj muaj raws li qhov yuav tsum tau precision qib ntawm cov casting qhov chaw. Piv txwv li, dej iav thiab silica sol ua ke peev txheej txheej txheem tuaj yeem siv rau qib qis lossis nruab nrab precision qib steel castings, thaum silica sol casting txheej txheem yuav tsum tau siv rau stainless hlau castings nrog rau qib precision.
