2. Yuav ua li cas yog cored hlau?
Cored hlau muaj ib tug tiv thaiv steel sheath nyob ib ncig ntawm ib tug tseem ceeb muaj xws li ua tib zoo xaiv alloys, minerals thiab hais xws li calcium, silicon, txhuas thiab carbon.
3. Lub luag haujlwm ntawm cored hlau ua si hauv steel ntau lawm?
Flux-cored hlau pab qhia cov ntsiab lus tseem ceeb thiab cov alloys rau hauv cov hlau molten, tso cai rau kev tswj xyuas cov hlau cov tshuaj muaj pes tsawg leeg thiab cov khoom. Nws txhim kho cov khoom siv kho tshuab, ua kom zoo dua cov qauv nplej, txo cov impurities, thiab ua kom zoo dua cov hlau kho cua sov teb.
4. Dab tsi yog qhov zoo ntawm kev siv cored hlau hauv steelmaking?
Siv cov cuab yeej siv cored hlau muaj ntau qhov zoo, xws li txhim kho cov peev txheej alloying, nce kev tswj hwm ntawm steel muaj pes tsawg leeg, thiab nce kev ua tau zoo thiab tus nqi ntawm cov txheej txheem steelmaking.
5. Dab tsi yog qhov txawv ntawm cored hlau siv hauv steelmaking?
Qhov sib txawv ntawm cored hlau feem ntau siv hauv steelmaking muaj xws li calcium cored hlau, ferroalloy cored hlau thiab carbon cored hlau.
6. Yuav ua li cas cored hlau pab rau ib tug tshwj xeeb steelmaking txheej txheem?
Cored hlau plays lub luag haujlwm tseem ceeb hauv desulfurization, deoxidation, suav nrog kev hloov pauv thiab lwm yam txheej txheem hauv cov txheej txheem steelmaking. Nws tuaj yeem txo cov impurities, txhim kho cov khoom siv kho tshuab, thiab txhim kho tag nrho cov khoom siv hlau.
7. Yuav ua li cas cored hlau txo impurities thiab tsis xws luag nyob rau hauv steel?
Flux-cored xaim tso cai rau kev tswj hwm ntawm cov hlau muaj pes tsawg leeg, ua rau cov qauv zoo dua thiab zoo dua qub. Qhov no txo cov impurities xws li sulfur, phosphorus thiab oxygen, yog li txo qhov tsis xws luag xws li pores thiab suav nrog.
8. Yuav ua li cas cored hlau txhim kho cov cuab yeej ntawm cov hlau?
Cov khoom siv kho tshuab ntawm cov hlau tuaj yeem raug kho kom tau raws li cov kev xav tau tshwj xeeb los ntawm kev qhia tshwj xeeb alloying ntsiab lus los ntawm flux-cored hlau. Qhov no suav nrog kev txhim kho toughness, ductility, hardness, lub zog thiab corrosion kuj.
9. Yuav ua li cas cored hlau txhim kho tag nrho cov kev ua tau zoo ntawm cov hlau?
Flux-cored hlau tso cai kom meej thiab muaj txiaj ntsig kev tswj hwm ntawm qhov sib ntxiv ntawm cov ntsiab lus alloying, txo qhov xav tau ntawm phau ntawv tuav thiab qhov hnyav. Qhov no txuag lub sijhawm, txo tib neeg kev ua yuam kev, thiab ua kom cov nqi ua haujlwm tau zoo los ntawm kev txo cov khoom pov tseg.
