Raws li cov xuab zeb casting foundry los ntawm Tuam Tshoj, RMC tuaj yeem cam khwb cia hlau los ntawmxuab zeb casting. Cam khwb cia hlau tuaj yeem muab faib ua cam khwb cia hlau thiab cam khwb cia carbon steel raws li nws cov tshuaj muaj pes tsawg leeg, thiab tseem tuaj yeem muab faib ua cov cuab yeej cam khwb cia, cam khwb cia tshwj xeeb steel, engineering thiab cov qauv casting thiab cam khwb cia hlau raws li nws cov yam ntxwv.
Los ntawm tshuaj muaj pes tsawg leeg
1. Cam khwb cia carbon steel. Cam khwb cia hlau nrog carbon ua lub ntsiab alloying caij thiab ib tug me me ntawm lwm yam ntsiab. Cam khwb cia carbon steel yuav muab faib ua cam khwb cia uas tsis muaj carbon steel, cam khwb cia nruab nrab carbon steel thiab cam khwb cia siab carbon steel. Cov ntsiab lus carbon ntawm cam khwb cia qis carbon steel yog tsawg dua 0.25%, cov ntsiab lus carbon ntawm cam khwb cia carbon steel yog nruab nrab ntawm 0.25% thiab 0.60%, thiab cov ntsiab lus carbon ntawm cam khwb cia siab carbon steel yog nruab nrab ntawm 0.6% thiab 3.0%. Lub zog thiab hardness ntawm cam khwb cia carbon steel nce nrog nce cov ntsiab lus carbon. Cam khwb cia carbon steel muaj qhov zoo hauv qab no: cov nqi tsim khoom qis dua, muaj zog dua, zoo dua toughness thiab ntau dua plasticity. Cam khwb cia carbon steel tuaj yeem siv los tsim cov khoom uas dais hnyav, xws li steel dov zeb sawv thiab hydraulic xovxwm hauv cov tshuab hnyav. Nws kuj tseem tuaj yeem siv los tsim cov khoom uas raug rau lub zog loj thiab cuam tshuam, xws li lub log, txuas txuas, bolsters thiab sab thav duab ntawm cov tsheb ciav hlau.
2. Cam khwb cia hlau alloy. Casting alloy steel tuaj yeem muab faib ua cov hlau tsis tshua muaj hlau (tag nrho cov ntsiab lus alloy tsawg dua lossis sib npaug li 5%), cam khwb cia hlau hlau (tag nrho cov ntsiab lus alloy yog 5% mus rau 10%) thiab cam khwb cia siab alloy steel (tag nrho cov hlau alloy. cov ntsiab lus ntau dua lossis sib npaug 10%).
Los ntawm kev siv cov yam ntxwv
1. Casting cuab yeej steel. Cam khwb cia hlau tuaj yeem muab faib ua cov cuab yeej casting steel thiab casting pwm steel.
2. Casting tshwj xeeb hlau. Casting tshwj xeeb hlau tuaj yeem muab faib ua cam khwb cia hlau stainless, cam khwb cia kub-resistant steel, cam khwb cia hnav-resistant steel, cam khwb cia npib tsib xee-raws li alloy, thiab lwm yam.
3. Cam khwb cia hlau rau engineering thiab qauv. Cam khwb cia hlau rau engineering thiab qauv yuav muab faib ua cam khwb cia carbon structural steel thiab cam khwb cia hlau structural steel.
4. Cast alloy steel. Nws tuaj yeem muab faib ua cov hlau tsis tshua muaj hlau, cam khwb cia nruab nrab alloy steel thiab cam khwb cia siab alloy steel.
304 thiab 316 cam khwb cia hlau stainless yog cov feem ntau siv stainless hlau. Ob leeg yog austenitic cam khwb cia hlau, uas tsis yog-magnetic los yog tsis muaj zog hlau nplaum. 430, 403, thiab 410 yog austenitic-ferritic stainless hlau nrog cov khoom sib nqus.
