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. Cam khwb cia hlau alloy. 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 khoom siv dav tshaj plawscam khwb cia hlau stainlessntawm steel foundries. 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.
Hauv kev tsim cov hlau castings, cam khwb cia hlau smelting yog txheej txheem tseem ceeb. Ua ntej txhua lub ncuav, yuav tsum muaj kev ntsuam xyuas ua ntej lub cub tawg. Qhov kev faib ua feem ntawm txhua yam tshuaj yuav tsum ua kom tau raws li cov neeg siv khoom xav tau thiab siv tau.
Txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau tshem tawm nws, nws yuav tsum tau ua tib zoo saib xyuas qhov zoo ntawm castings. Txawm li cas los xij, hauv Suav cov chaw tsim khoom, cov khoom siv hlau siv rau smelting tau muab faib ua ob hom: cov khoom siv rov ua dua tshiab thiab cov ntaub ntawv tshiab. Cov khoom siv rov ua dua yog hais txog cov txheej txheem nchuav thiab riser ntawm castings, seem castings, thiab lwm yam. Ua ntej siv, cov tshuaj muaj pes tsawg leeg thiab qib yuav tsum tau soj ntsuam kom meej, thiab cov impurities thiab oxide nplai yuav tsum raug tshem tawm los ntawm kev txhaj tshuaj blasting lossis sandblasting, thiab tom qab ntawd muab tso tseg. , los yog cov khoom siv rov ua dua yuav tsum tau smelted thiab nchuav rau hauv cov khoom siv rau kev siv.
Cov ntaub ntawv tshiab yog ingots ua los ntawm qee qib ntawm cov hlau tuav lossis cov khoom seem, nrog rau feem ntau siv ferroalloys thiab cov ntaub ntawv hlau ntshiab. Cov hlau tuav thiab cov ingots ntawm qee cov qib yuav tsum tau soj ntsuam rau qhov muaj pes tsawg leeg thiab ua tau raws li cov qauv, thiab qhov luaj li cas ntawm cov tuav yuav tsum tau ua raws li qhov ntau thiab tsawg ntawm lub cub hluav taws xob thiab crucible.
