Cov cam khwb cia hlau yog hais txog cov hlau siv rau qhov ua khoom siv ntawm steel txhabCov. Cov hlau cam yuav tsum tau siv thaum lub zog ntawm kev nrum yog siab thiab siv cov hlau cam tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua. Txawm li cas los xij, qhov npliag ntawm molten steel ntawm cam khwb cia steel tsis zoo li qhov zoo ntawm cov cam khwb cia hlau, yog li tuab ntawm cov txheej txheem pouring yuav tsum tsis txhob muaj tsawg heev thiab cov duab yuav tsum tsis txhob nyuaj dhau. Thaum cov ntsiab lus silicon yog tswj hwm nyob rau sab saud, qhov fluidity ntawm molten steel tuaj yeem hloov kho.
Cov cam khwb cia hlau tuaj yeem muab faib ua cov hlau cam khwb cia hlau thiab cam khwb cia carbon hlau raws li nws cov tshuaj lom neeg, thiab tseem tuaj yeem muab faib rau cov khoom siv nrum hlau, nrum hlau tshwj xeeb, kev tsim vaj tsev thiab cov txheej txheem cam thiab cam khwb cia alloy hlau raws li nws cov yam ntxwv.
Los ntawm cov tshuaj lom neeg muaj pes tsawg leeg
1. Nrum cov hlau. Nrum cov hlau nrog cov pa roj carbon ua cov ntsiab lus alloying thiab ib qho me me ntawm lwm cov ntsiab lus. Cov cam khwb cia carbon hlau tuaj yeem muab faib rau cov cam khwb cia cov hlau tsis tshua zoo, nrum nruab nrab cov pa roj carbon hlau thiab nrum carbon hlau loj. Cov pa roj carbon cov ntsiab lus ntawm cov cam khwb cia cov pa roj carbon tsawg yog tsawg dua 0.25%, cov ntsiab lus carbon ntawm cov cam khwb cia carbon steel yog nruab nrab ntawm 0.25% thiab 0.60%, thiab cov ntsiab lus carbon ntawm cov nrum siab carbon steel yog nruab nrab ntawm 0.6% thiab 3.0%. Lub zog thiab tawv tawv ntawm cam khwb cia carbon steel nce nrog qhov nce ntawm cov ntsiab lus carbon. Cov cam khwb cia carbon hlau muaj qhov zoo li nram no: qis tus nqi tsim khoom, lub zog siab dua, zoo dua kev coj nruj thiab siab dua yas. Cov cam khwb cia carbon hlau tuaj yeem siv los tsim cov khoom uas muaj lub nra hnyav, xws li steel dov zeb sawv ntsug thiab hydraulic xovxwm puag hauv cov tshuab hnyav. Nws kuj tseem siv tau los ua cov khoom seem uas raug rau cov tub rog loj thiab cuam tshuam, xws li lub log, txuas, tsheb thaiv thiab sab ntug ntawm cov tsheb ciav hlau.
2. Nrum alloy hlau. Casting alloy hlau muaj peev xwm raug faib ua cov cam khwb cia tsawg alloy steel (tag nrho cov ntsiab lus alloy yog tsawg dua lossis sib npaug li 5%), cam khwb cia alloy hlau (tag nrho cov ntsiab lus hlau yog 5% txog 10%) thiab cam khwb cia siab alloy hlau (tag nrho cov alloy cov khoom muaj ntau dua lossis sib npaug 10%).
Los ntawm kev siv tus yam ntxwv
1.Cov cuab tam steel. Cov cuab yeej cam khwb cia steel tuaj yeem muab faib ua cov cuab tam casting thiab cov hlau casting pwm.
2. Nrum cov hlau tshwj xeeb. Casting tshwj xeeb steel tuaj yeem muab faib ua cov cam khwb cia steel hlau, cam khwb cia kub-resistant hlau, cam khwb cia coj-resistant hlau, nrum npib tsib xee-ua raws alloy, thiab lwm yam.
3. Nrum hlau rau engineering thiab cov qauv. Cam khwb cia hlau rau engineering thiab qauv yuav muab faib ua cam khwb cia cov yam ntxwv steel thiab cam khwb cia hlau yam ntxwv hlau.
4. Nrum cov hlau alloy. Nws muaj peev xwm raug faib ua cam khwb cia tsawg alloy steel, cam khwb cia nruab nrab alloy steel thiab cam khwb cia siab alloy steel.
304 thiab 316 cam khwb cia hlau yog qhov feem ntau siv cov hlau tsis muaj hlau nyob ntawm steel foundriesCov. Ob leeg yog cov hlau cam austenitic, tsis yog hlau nplaum lossis tsis muaj zog. Cov 430, 403, thiab 410 yog hlau austenitic-ferritic stainless hlau nrog cov khoom muaj hlau nplaum.
Hauv kev ua cov hlau cam, cam hlau smelting yog txheej txheem tseem ceeb. Ua ntej txhua qhov nchuav, ib qho kev soj ntsuam ua ntej npaj taws ua kom sov. Qhov kev faib ua feem ntawm txhua yam tshuaj yuav tsum ua kom tau raws cov kev cai ntawm cov neeg siv khoom thiab cov kev siv ua kom zoo
Txhawm rau txhawm rau txhim kho qhov kev nrawm nrawm thiab kom ntseeg tau cov khoom zoo ntawm cov neeg tuaj yeem, cov khoom noj nrog cov nplai tsim nyog muaj feem ntau siv rau txawv teb chaws. Txawm li cas los xij, hauv cov hauv paus hauv Suav, cov khoom siv hlau siv rau kev muab cov neeg sib tsoo tau faib ua ob hom: cov khoom siv rov ua dua tshiab thiab cov ntaub ntawv tshiab. Rov qab siv cov khoom siv yog hais txog qhov txheej txheem pouring thiab riser ntawm kev tso dag, kos seem, thiab lwm yam Ua ntej siv, cov tshuaj lom neeg thiab qib yuav tsum raug txheeb xyuas kom meej meej, thiab cov nplaim hluavtaws thiab oxide nplai yuav tsum tau tshem tawm los ntawm kev tua blasting lossis sandblasting, thiab tom qab ntawd teeb ib sab , lossis cov khoom siv rov ua dua tshiab yuav tsum tau muab txhuam thiab muab nchuav rau hauv cov khoom siv rau kev siv.
Cov ntaub ntawv tshiab yog cov khoom siv los ntawm qee qib ntawm cov hlau tuav lossis khoom siv, nrog rau cov khoom siv hlau thiab cov khoom siv hlau ntshiab. Cov hlau teeb thiab ntawm cov qib kawm yuav tsum tau ntsuas rau qhov muaj pes tsawg leeg thiab ua tau raws li cov qauv, thiab qhov loj me ntawm cov kab yuav tsum tau ua raws li qhov ntau thiab tsawg ntawm lub tshuab hluav taws xob thiab qhov cub tau tawg.
