Calcium Silicon yog dab tsi?

Calcium silicon (CaSi) yog ferroalloy feem ntau ntawm calcium thiab silicon, nrog rau cov khoom me me ntawm lwm cov ntsiab lus. Nws qhov muaj pes tsawg leeg sib txawv nyob ntawm cov txheej txheem tsim khoom thiab cov ntawv thov. Nws yog ib qho tseem ceeb ntxiv nyob rau hauv ntau yam txheej txheem metallurgical vim nws muaj peev xwm hloov kho cov khoom ntawm cov hlau molten. Lub luag haujlwm tseem ceeb ntawm calcium silicon nyob rau hauv nws lub peev xwm deoxidizing thiab desulfurizing.

Chemical Composition thiab Properties

Cov tshuaj muaj pes tsawg leeg ntawm calcium silicon suav nrog feem pua ​​ntawm silicon (feem ntau ntawm 20% mus rau 70%) thiab cov calcium ntau (feem ntau ntawm 15% thiab 40%). Lwm cov ntsiab lus yuav muaj nyob rau hauv me me, xws li hlau, txhuas, thiab manganese. Cov khoom me me no tuaj yeem cuam tshuam tag nrho cov khoom thiab kev ua haujlwm ntawm cov hlau. Qhov muaj pes tsawg leeg yog qhov tseem ceeb hauv kev txiav txim siab nws qhov tsim nyog rau kev siv sib txawv. Piv txwv li, cov ntsiab lus calcium ntau dua tuaj yeem nyiam hauv qee cov txheej txheem steelmaking rau kev txhim kho desulfurization.

Cov txheej txheem tsim khoom

Calcium silicon feem ntau yog tsim los ntawm kev txo cov carbothermic hauv hluav taws xob arc rauv. Cov txheej txheem no suav nrog cua sov sib xyaw ntawm limestone (calcium carbonate), silica (silicon dioxide), thiab coke (carbon) kom kub siab. Qhov kub siab ua rau cov tshuaj tiv thaiv kab mob, ua rau kev tsim ntawm calcium silicon. Kev tswj xyuas qhov kub thiab txias, qhov sib piv ntawm cov khoom siv raw, thiab cov cua sov cua sov yog qhov tseem ceeb hauv kev ua tiav cov tshuaj lom neeg xav tau thiab qhov zoo ntawm cov khoom kawg. Cov tuam ntxhab sib txawv tuaj yeem siv cov kev hloov pauv ntawm cov txheej txheem no, ua rau muaj qhov sib txawv me ntsis ntawm qhov tshwm sim alloy.

Kev siv ntawm Calcium Silicon

Steelmaking

Ib qho ntawm cov kev siv tseem ceeb tshaj plaws ntawm calcium silicon yog nyob rau hauv steelmaking. Nws ua haujlwm ua lub zog deoxidizer, tshem tawm cov pa oxygen los ntawm cov hlau molten. Qhov no yog qhov tseem ceeb rau kev txhim kho cov cuab yeej cuab tam ntawm cov khoom siv hlau kawg, txhim kho nws lub zog, ductility, thiab weldability. Tsis tas li ntawd, calcium silicon pab txhawb rau desulfurization, ntxiv refining cov hlau thiab txo undesirable impurities.

Cast Iron Production

Hauv kev tsim cov hlau cam khwb cia, calcium silicon yog siv los txhim kho microstructure thiab mechanical zog ntawm cov castings. Nws pab ua kom zoo dua cov qauv graphite, ua rau txhim kho machinability thiab txhim kho txhua yam muaj zog. Qhov no ua rau calcium silicon ib qho tseem ceeb additive rau kev ua tau zoo cam khwb cia hlau Cheebtsam.

Lwm Daim Ntawv Thov

Tshaj li steel thiab cam khwb cia hlau ntau lawm, calcium silicon pom cov ntawv thov hauv ntau lwm cov txheej txheem metallurgical, suav nrog kev tsim cov aluminium alloys thiab lwm yam hlau tsis-ferrous. Nws muaj peev xwm hloov kho cov khoom hlau ua rau nws muaj ntau yam additive nyob rau hauv ntau hom kev siv.

Kev xav txog kev nyab xeeb

Thaum calcium silicon yog qhov tseem ceeb hauv ntau qhov kev lag luam, kev tiv thaiv kev nyab xeeb yog qhov tseem ceeb thaum tuav thiab siv. Nws yog ib qho tseem ceeb uas yuav tsum hnav cov khoom tiv thaiv tus kheej tsim nyog (PPE), nrog rau cov hnab looj tes, tsom iav kev nyab xeeb, thiab kev tiv thaiv ua pa, kom tsis txhob muaj cov tawv nqaij thiab ua pa ua pa. Kev khaws cia thiab tuav cov txheej txheem kom raug kuj tseem tsim nyog los tiv thaiv kev nqus plua plav thiab muaj peev xwm ua rau hluav taws kub. Nco ntsoov sab laj nrog daim ntawv qhia kev nyab xeeb (SDS) rau cov lus qhia tshwj xeeb uas muab los ntawm tus neeg muag khoom.

Xaiv txoj cai Calcium Silicon

Xaiv cov qib uas tsim nyog ntawm calcium silicon nyob ntawm qhov kev thov tshwj xeeb. Cov yam ntxwv xws li cov ntsiab lus calcium thiab silicon xav tau, theem ntawm impurities, thiab cov khoom xav tau ntawm cov khoom kawg tag nrho ua lub luag haujlwm hauv kev xaiv. Ua haujlwm nrog tus neeg muag khoom muaj npe nrov uas tuaj yeem muab cov ncauj lus kom ntxaws thiab kev lees paub zoo yog qhov tseem ceeb rau kev ua tiav ntawm koj daim ntawv thov. Sab hauv Mongolia Xinxin Silicon Kev Lag Luam Co., Ltd yog ib lub chaw muag khoom zoo tshaj plaws calcium silicon, muab ntau qib kom tau raws li kev xav tau ntawm kev lag luam sib txawv.
