Calcium silicon granules yog tsim los ntawm silicon, calcium thiab me me ntawm impurities xws li hlau, txhuas, carbon, sulfur thiab phosphorus. Ntawm lawv, cov ntsiab lus silicon feem ntau yog nyob nruab nrab ntawm 55% -65%, thiab cov ntsiab lus calcium nyob nruab nrab ntawm 24% -31%. Silicon thiab calcium yog cov khoom xyaw tseem ceeb, uas ua lub luag haujlwm tseem ceeb hauv nws daim ntawv thov hauv steelmaking, casting thiab lwm yam kev lag luam, thaum lub ntsiab lus ntawm impurity ntsiab yuav tsum tau tswj nruj me ntsis kom ntseeg tau qhov zoo thiab kev ua tau zoo.calcium silicon granules.

Silicon calcium granules nyob nruab nrab ntawm 0.2-2 hli loj, uas yog ib daim ntawv me me. Nws qhov loj me yog qhov sib xws. Qhov kev faib tawm zoo sib xws no ua rau cov khoom sib txuas tau zoo dua thiab hnov mob nrog lwm yam tshuaj thaum siv. Piv txwv li, nyob rau hauv cov txheej txheem steelmaking, nws muaj peev xwm muab faib ua ntau tusyees nyob rau hauv lub molten steel los ua lub luag hauj lwm nyob rau hauv deoxidation thiab desulfurization. Cov tsos mob feem ntau yog grey los yog grey-dub hais nrog ib tug kuj ntxhib nto, uas yuav pab tau kom nws cov kev sib txhuam thiab adhesion nrog lwm yam tshuaj thiab txhim kho cov tshuaj tiv thaiv efficiency.

Tsis zoo li qub 0-2mm CaSi granules, peb 0.2-2mm granules tshem tawm cov hmoov ultrafine me dua 0.2mm. Dab tsi yog cov teeb meem nrog ultrafine hmoov?

Yooj yim rau clumping:Nws hloov mus rau hauv av nkos sib xws thaum raug cov dej noo, ua rau tsis ruaj khov los ntawm cov hlau feeder.

Flowability:Qhov siab ntawm cov hmoov zoo ua rau lub Hall nyhuv qeeb qeeb, yooj yim clogging cov yeeb nkab.

Haus luam yeeb thiab pov tseg:Cov hmoov zoo yog nqus tau yooj yim los ntawm cov plua plav collector thaum pub mis.

Cored hlau yog tsim los ntawm wrapping hmoov nyob rau hauv steel sawb los ua ib tug hlau, uas yog ces muab tob rau hauv molten hlau. Qhov loj ntawm cov hmoov yog yuav tsum nruj heev.

Calcium silicon granules siv

Steelmaking deoxidizer:

Thaum lub sij hawm steelmaking txheej txheem, silicon thiab calcium nyob rau hauv silicon -calcium granules muaj ib tug muaj zog affinity nrog oxygen nyob rau hauv molten steel, thiab muaj peev xwm hnov mob sai sai nrog oxygen kom tshem tawm cov pa oxygen, yog li txo cov pa oxygen hauv cov hlau, txo qhov tsis xws luag xws li pores thiab inclusions nyob rau hauv cov hlau, thiab kev txhim kho qhov zoo thiab kev ua tau zoo ntawm steel. Nyob rau tib lub sijhawm, lubdeoxidationcov khoom yog yooj yim rau ntab thiab tso tawm, ua rau cov hlau molten purer.

Steelmaking alloying tus neeg sawv cev:

Silicon thiab calcium ntxiv rau cov hlau raws li cov ntsiab lus alloying los kho cov tshuaj muaj pes tsawg leeg ntawm cov hlau, txhim kho lub zog, hardness, toughness, plasticity thiab lwm yam khoom siv ntawm cov hlau, txhim kho kev ua haujlwm thiab kev siv cov hlau, thiab ua tau raws li cov kev xav tau ntawm cov qib steel sib txawv.

Casting inoculant:

Hauv kev tsim khoom, calcium silicon granules tuaj yeem siv los ua inoculants, uas tuaj yeem txhim kho cov graphite morphology thiab faib cov hlau cam khwb cia, ua graphite finer thiab ntau yam zoo, yog li txhim kho lub zog, toughness, hnav tsis kam thiab lwm yam khoom siv ntawm cov hlau cam khwb cia, txo qhov tsis xws luag, thiab txhim kho qhov zoo thiab yield ntawm castings.

Lwm qhov chaw:

Ntxiv nrog rau kev lag luam metallurgical, SiCa granules kuj tau siv hauv qee qhov chaw. Piv txwv li, hauv kev ua liaj ua teb, nws tuaj yeem siv los ua calcium silicon chiv rau kev txhim kho av, txhim kho av fertility thiab dej thiab chiv tuav peev xwm, thiab txhawb kev loj hlob thiab kev loj hlob ntawm cov qoob loo; hauv kev tsim cov ntaub ntawv hauv tsev, nws tuaj yeem siv los tsim cov cement, pob zeb, thiab lwm yam, los txhim kho lub zog thiab durability ntawm cov ntaub ntawv.

FAQ

Q: Qhov txawv ntawm 0.2-2mm thiab 0-2mm yog dab tsi? Nws kim npaum li cas?

A: 0-2mm muaj cov hmoov ultrafine me dua 0.2mm, uas yooj yim clumps thiab clogs cov hlab. Peb sieve tawm cov hmoov ultrafine, uas ua rau tus nqi nce me ntsis, tab sis ua rau muaj kev ruaj ntseg ntawm cov hlau zoo dua. Cored hlau manufacturers txhua tus qhia qhov no.

Q: Qhov feem pua ntawm koj 0.2-2mm calcium silicon hmoov yog tsawg dua 0.2mm?

A: Peb tswj nws kom tsis pub dhau 3%. Cov qauv kev lag luam feem ntau tsawg dua lossis sib npaug li 5%, tab sis peb nruj dua. Daim ntawv qhia txog qhov loj me yog suav nrog cov khoom xa tuaj.

Q: Cov hmoov puas tseem siv tau yog tias nws ntub dej?

A: Cov calcium hauvSiCa hmoovyog heev reactive thiab clumps thaum damp, txo nws flowability. Peb pom zoo kom tsis txhob siv nws, txwv tsis pub cov hlau feeder yuav muaj kev noj tsis ruaj khov thiab tej zaum yuav ua rau cov hlau tawg. Peb cov hmoov yog lub tshuab nqus tsev- ntim lossis khaws cia hauv cov dej noo- cov ntaub ntawv pov thawj, thiab yuav tsum khaws cia rau hauv qhov chaw qhuav.

Q: Qhov kev txiav txim yam tsawg kawg nkaus yog dab tsi? Koj puas tuaj yeem xa cov qauv ua ntej?

A: Yam tsawg kawg nkaus kom muaj nuj nqis yog 25 tons (ib lub thawv). Cov qauv muaj pub dawb; koj tsuas yog yuav tsum them tus nqi shipping.
