Casting spheridizing tus neeg sawv cev yog kev ntxiv ntxiv siv los txhawb cov spheroidization ntawm graphite hauv kev tsim cov hlau nplaum. Lub hom phiaj ntawm graphite spheroidization yog txhawm rau txhim kho cov khoom ntawm cov hlau cam khwb cia, tshwj xeeb yog ua kom muaj zog thiab cuam tshuam tsis kam. Los ntawm kev tswj hwm daim ntawv ntawm graphite hauv cam khwb cia hlau, tus neeg sawv cev sib xyaw los ntawm Firerical Graphite, yog li los txhim kho lub cam khwb cia thiab cov kws kho mob ntawm cov hlau cam khwb cia.
1. Lub hauv paus ntsiab lus ntawm spheridizing tus neeg sawv cev
Hauv cov hlau cam khwb cia, daim ntawv ntawm graphite feem ntau yog cub graphite, uas yuav ua rau rau cov khoom siv tsis zoo ntawm cov hlau cam khwb cia ntawm cov hlau cam khwb cia ntawm cov hlau cam khwb cia ntawm cov hlau cam khwb cia ntawm cov hlau cam khwb cia. Spheroiding tus neeg sawv cev tuaj yeem raug ntxiv los pov cov hlau thaum cov txheej txheem smelting los hloov cov ntawv loj hlob ntawm graphite rau spherical graphite. Spherical Graphite muaj cov khoom siv tshuab hluav taws xob zoo dua li flake graphite, tshwj xeeb tshaj yog nyob rau hauv lub zog tensile, cuam tshuam, ductility, ductility, ductility thiab li ntawd.
Spheroiding cov neeg sawv cev feem ntau muaj qee cov ntsiab lus nrog kev txo cov khoom, uas tuaj yeem ua rau cov pob cam khwb cia hauv cov pob core graphite thiab txhawb nqa kev loj hlob ntawm graphite.
2. Kev sib xyaw ntawm spheridizing tus neeg sawv cev
Cov neeg sawv cev ib txwm muaj feem cuam tshuam nrog cov hauv qab no:
- Tsis tshua muaj ntiaj teb cov ntsiab lus:xws li yttrium, cerium, cerium, thiab lwm yam, tsis tshua muaj cov xwm txheej ntawm cov hlau cam khwb cia ntawm cov nodulators.
- Magnesium:Magnesium yog ib qho ntawm cov ntsiab lus feem ntau siv nyob rau hauv spheroiding tus neeg sawv cev, tab sis nws siv yuav tsum tau ua kom muaj kev tswj hwm zoo heev vim tias muaj peev xwm ua ib qho kev ua haujlwm siab nyob rau hauv cov melt thiab yog ib qho yooj yim kom hnov mob nrog lwm yam.
- Calcium, strontium:Calcium thiab strontium tseem tuaj yeem txhim kho cov nyhav ntawm cov hlau cam khwb cia hauv qee qhov kev mob, tab sis lawv cov teebmeem tsis yog qhov tseem ceeb uas tsis tshua muaj neeg thiab cov magnesium.
3. Hom spheriding
Nyob ntawm lawv cov muaj pes tsawg leeg thiab siv, cov neeg sawv cev sib txawv tuaj yeem faib ua ntau hom:
- Cov hlau nplaum raws cov spheroidizers:Magnesium raws li lub ntsiab tivthaiv, feem ntau ua ke nrog lwm cov hlau hais (xws li calcium, strontium, thiab lwm yam). Haum rau spheroidization ntawm nruab nrab thiab tsawg cov pa roj carbon cam khwb cia hlau.
- Lub ntiaj teb tsis tshua muaj zog magnesium puag spheroidizing tus neeg sawv cev:Ntxiv lub ntiaj teb tsawg (xws li yttrium, cerium, cerium, cerium, cerium, cerium, cerium, cerium, cerium, cerium, cerium, cerium. Haum rau kev ua haujlwm siab pov cov hlau.
- Cov tshuaj calcium npias spheroidizing tus neeg sawv cev:Lub ntsiab tivthaiv yog calcium, uas tuaj yeem txhim kho kev ua haujlwm casting ntawm cam khwb cia hlau, tab sis cov nyhuv spheroiding feem ntau tsis zoo li cov hlau nplaum sib luag.
4. Kev siv ntawm spheriding tus neeg sawv cev
Spheroiding cov neeg sawv cev feem ntau yog ntxiv rau cam khwb cia hlau hauv ib ntawm ob txoj kev:
- Ntxiv Ntxiv Txoj Kev:Tus neeg sawv cev sab nrauv yog ncaj qha ntxiv rau cov melted cam khwb cia hlau, feem ntau yog siv cov hlau cam melting rauv los yog hluav taws xob cua sov.
- Alloy Ntxiv Txoj Kev:Tus neeg sawv cev sib txawv yog ntxiv rau cov hlau nplaum ua ke nrog lwm cov hlau hais ua ib feem ntawm cov alloy.
Tus nqi thiab sijhawm ntawm nodulating tus neeg sawv cev yog qhov tseem ceeb heev rau qhov kawg nodulating nyhuv. Feem ntau, tus nqi ntawm nodulating tus neeg sawv cev ntxiv yuav tsum tau txiav txim siab raws li cov kev sib xyaw ntawm cam khwb cia hlau, qhov loj me ntawm cov Casting thiab kev yuav tsum tau ua.
5. Tswj cov nyhuv spheroiding
Cov nyhuv spheroidization ncaj qha cuam tshuam qhov zoo ntawm cov hlau cam khwb cia. Tswjhwm cov txiaj ntsig spheroidiation yuav tsum tau mloog cov lus hauv qab no:
- Melting kub:Siab dhau los lossis qis heev melting kub yuav cuam tshuam cov nyhuv ntawm spheroiding tus neeg sawv cev. Feem ntau, qhov kub melted yuav tsum tau khaws cia tsis pub dhau ib qho.
- Tus nqi ntawm nodulating tus neeg sawv cev ntxiv:Ntau dhau los yog tsawg dhau nodulating tus neeg sawv cev yuav ua rau tsis zoo nodulating effections graphite, thiab tej zaum tseem yuav tsim graphite los yog graphite tsis tuaj yeem no bodulating.
- Sib tov thiab tuav lub sijhawm:Tom qab ntxiv cov nodulator, nws yog ib qho tsim nyog los xyuas kom meej tias cov no stirred thiab khaws cia sov kom cov nodulator tuaj yeem hnov mob nrog cov hlau cam.
6. Xaiv cov spheidesizing tus neeg sawv cev
Kev xaiv ntawm qhov tsim nyog nodulator feem ntau yog raws li cov hauv qab no:
- Composition ntawm cam khwb cia hlau:Ntau hom hlau cam khwb cia (xws li hlau cam khwb cia hlau, pawg hlau, zas xim dawb, thiab lwm yam) muaj cov kev xav tau sib txawv rau nodulators.
- Yuav tsum muaj rau kev siv cov duab xwm:Qhov sib txawv sib txawv yuav tsum muaj cov khoom sib txawv, thiab xaiv cov neeg sawv cev sib txawv, thiab cov neeg sawv cev ntawm cov neeg muaj lub zog ntawm lub zog thiab tawv ntawm castings.
- Qhov sib npaug ntawm tus nqi thiab kev ua tau zoo:Tus nqi sib txawv ntawm cov nodulators sib txawv yog loj, thiab nws yog ib qho tsim nyog los xaiv cov nqi siv hluav taws xob raws li kev lag luam.
Casting spheriding tus neeg sawv cev ua lub luag haujlwm tseem ceeb hauv kev txhim kho cov kev ua tau zoo ntawm cov hlau cam khwb cia, hnav tsis kam tiv thaiv hlau. Qhov zoo thiab kev ua tau ntawm cam khwb cia hlau tuaj yeem txhim kho kom txhim kho los ntawm kev xaiv nodulator thiab siv nws kom raug. Yog li ntawd, kev tshawb fawb thiab kev siv cov neeg sawv cev sib txawv ib txwm yog cov ncauj lus tseem ceeb hauv kev lag luam meting.
