Puas yog FeSi70 yog ib qho kev lees paub kev lag luam- qib khoom? Nws ua raws li ASTM/GB tus qauv? - Kev Paub

Kev lees paub tias yog kev lag luam-Qib khoom

FeSi70 yog cov khoom siv tseem ceeb hauv kev lag luam metallurgical, tshwj xeeb tshaj yog nyob rau hauv steelmaking thiab foundry ua haujlwm. Nws cov xwm txheej raws li tus qauv kev lag luam yog cemented los ntawm ntau yam:

Kev siv thoob ntiaj teb:Nws yog tsim thiab siv nyob rau hauv ib tug loj teev nyob rau hauv lub ntiaj teb no, tshwj xeeb tshaj yog nyob rau hauv lub teb chaws uas tseem ceeb steel thiab foundry industries xws li Tuam Tshoj, Russia, Norway, Brazil, thiab lub tebchaws United States.

Standardized ntau lawm:Cov neeg tsim khoom loj tsim nws raws li cov lus qhia tshwj xeeb tshuaj kom tau raws li qhov xav tau ntawm cov neeg siv khoom loj.

Txoj Cai Ua Raws Cai:Nws siv tau teev nyob rau hauv cov ntaub ntawv qhia txog cov qib steel thiab cov txheej txheem casting, txhais tau tias nws qhov zoo yog qhov yuav tsum tau ua raws li kev cog lus hauv ntau cov saw hlau.

Muaj cov ntaub ntawv pov thawj:Nws yog niaj hnub muab nrog aCertificate of Analysis (CoA)uas txheeb xyuas nws cov muaj pes tsawg leeg tiv thaiv tus qauv lees paub.

Ua raws li ASTM Standards

ASTM International (yav tas los American Society for Testing and Materials) muab cov qauv rau ntau yam ferroalloys, suav nrog ferrosilicon. Tus qauv tseem ceeb rau FeSi70 yog:

ASTM A1008/A1008M - Txuj Specification rau Steel, Sheet, Txias-Rolled, Carbon, Structure, High-Strength Low-Alloy, High-Strength Low-Alloy nrog Txhim Kho Formability, Hardened, Required B.

(Ceeb Toom: Thaum qhov no yog steel spec, nws hais txog kev siv ferroalloys zoo li FeSi rau deoxidation thiab alloying.)

Txawm li cas los xij, tus qauv ncaj qha rau covferroalloy nws tus kheejyog:

ASTM A1025 - Txuj Specification rau Ferroalloys.

Qhov kev qhia tshwj xeeb no suav nrog ntau yam ferroalloys, suav nrog ferrosilicon, thiab tso cai rau kev yuav khoom ntawm cov khoom siv tshuaj tshwj xeeb uas tau pom zoo los ntawm tus neeg yuav khoom thiab tus muag khoom. Thaum nws tsis sau "FeSi70" raws li qib taag, nws muab lub hauv paus rau kev txiav txim qib 70% silicon. Hauv kev xyaum, North American mills thiab foundries qhia FeSi70 los ntawm kev xa muscov ntaub ntawv tsim tawmlos yogkev cog lus yuav khoomuas lav qhov tsawg kawg nkaus ntawm 70% Si, feem ntau ua raws cov tshuaj lom neeg muaj nyob hauv cov lus teb dhau los.

Nyob rau hauv Teb Chaws Asmeskas kev lag luam, koj yuav nquag pom cov ntaub ntawv sau npe"60-14"los yog"75-20", qhov twg thawj tus lej yog Si% thiab qhov thib ob yog Al% (piv txwv li, 60% Si, 14% Al). A 70% Si qib yuav yog qhov kev cai zoo sib xws.

Ua raws li GB Standards (Suav National Standards)

Tuam Tshoj yog ib qho ntawm cov neeg tsim khoom loj tshaj plaws thiab cov neeg siv khoom ntawm ferrosilicon, thiab nws cov qauv hauv lub tebchaws muaj kev cuam tshuam loj heev hauv ntiaj teb. Tus qauv tseeb rau FeSi70 hauv Suav teb yog:

GB/T 2272 - Ferrosilicon

Cov qauv no qhia meej meej cov tshuaj muaj pes tsawg leeg rau ntau qib ntawm ferrosilicon, suav nrog FeSi70.

Raws liGB/T 2272, tus qauv rauFeSi 70qhia cov hauv qab no:

Qib	Chemical Composition (%), Tsawg dua lossis sib npaug los yog Ntau dua lossis sib npaug
	Si	Al	Ca	C	P	S	Mn
	Ntau dua lossis sib npaug	Tsawg dua los yog sib npaug	Tsawg dua los yog sib npaug	Tsawg dua los yog sib npaug	Tsawg dua los yog sib npaug	Tsawg dua los yog sib npaug	Tsawg dua los yog sib npaug

Lus Cim rau GB / T 2272:

Tus qauv guarantees aTsawg kawg ntawm 70.0% Silicon.

Nws teevqhov siab tshaj plawsrau cov impurities tseem ceeb xws li Aluminium (Al), Calcium (Ca), Carbon (C), Phosphorus (P), thiab Sulfur (S).

Cov ntsiab lus hlau (Fe) yog qhov sib npaug, feem ntau nyob ib ncig ntawm 25-28%.

Kuj tseem muaj qib zoo liFeSi75(min. 75% Si) thiabFeSi65 (min. 65% Si) them raws li tus qauv qub.

Tus qauv GB no yog tus qauv siv rau cov khoom muag hauv Suav teb hauv kev lag luam thiab rau kev xa tawm. Thaum nrhiav los ntawm cov neeg muag khoom hauv Suav teb, thov cov khoom siv uas ua rawsGB/T 2272 FeSi70yog tus qauv.

Lwm Cov Txheej Txheem Thoob Ntiaj Teb ntsig txog

ISO (International Organization for Standardization): ISO 5445: 1980 yog tus qauv qub thoob ntiaj teb rau ferrosilicon, tab sis nws tau raug hloov pauv los ntawm cov qauv hauv tebchaws xws li GB / T 2272 lossis tus tsim khoom- tshwj xeeb tshwj xeeb hauv Tebchaws Europe thiab Asmeskas.

DIN (Lub koom haum German rau Standardization):Lub teb chaws Yelemees muaj nws tus kheej cov qauv (piv txwv li, DIN 17560), tab sis dua, GB / T 2272 yog ntau thoob ntiaj teb siv rau qib no hauv kev lag luam thoob ntiaj teb niaj hnub no.
