High Carbon Silicon (High Carbon Silicon) yog cov khoom siv hlau uas muaj cov pa roj carbon siab (C) thiab silicon (Si), uas yog siv hauv hlau thiab hlau smelting thiab foundry kev lag luam. Nws yog ib qho tseem ceeb additive nyob rau hauv metallurgical kev lag luam vim hais tias ntawm nws cov nqi qis thiab deoxidizing zoo heev thiab carbon-txhim kho zog.
siab carbon silicon tseem ceeb nta
1. Deoxygenation thiab txhim kho
High-carbon silicon tuaj yeem siv los ua cov deoxidizer zoo heev hauv cov txheej txheem steelmaking. Nrog nws cov ntsiab lus silicon siab, nws tuaj yeem hnov mob nrog oxygen hauv cov hlau los tsim cov oxides ruaj khov (xws li SiO₂), tshem tawm cov pa oxygen impurities ntawm hlau thiab txhim kho cov purity ntawm hlau.
2. Carbonizer
High-carbon silicon kuj tseem siv tau los ua carburizer, tshwj xeeb tshaj yog siv tau zoo hauv cov hlau cam khwb cia grey thiab cov hlau ductile. Ntxiv cov pa roj carbon ntau tuaj yeem muab silicon thaum nce cov ntsiab lus carbon, yog li ua tiav cov txiaj ntsig ntawm kev tswj cov tshuaj muaj pes tsawg leeg ntawm castings thiab txhim kho cov khoom siv kho tshuab.
3. Txo cov nqi smelting
Piv nrog rau cov khoom siv ntxiv uas siv cov pa roj carbon thiab silicon ib leeg, cov pa roj carbon ntau silicon tuaj yeem muab ob qho tib si, ua kom yooj yim rau cov txheej txheem smelting thiab txo cov nqi khoom. Nws tus nqi feem ntau yog qis dua li cov ntshiab silicon alloys, ua rau nws xaiv ntau lub tuam txhab steel los txo cov nqi tsim khoom.
4. Kev ua haujlwm ruaj khov
High-carbon silicon muaj zoo solubility nyob rau hauv molten steel thiab tsis yooj yim los tsim slag los yog inclusions, uas yuav pab tswj lub purity thiab stability ntawm molten steel. Tsis tas li ntawd, kev siv cov roj carbon silicon siab kuj tuaj yeem txo lub sijhawm melting, yog li kev txhim kho cov smelting efficiency.
5. Kev txhim kho hauv casting zoo
Thaum lub sij hawm casting txheej txheem, siab carbon silicon tuaj yeem txhim kho cov qauv graphite ntawm castings thiab nce cov ntsiab lus ferrite, yog li txhim kho qhov cuam tshuam thiab cov khoom siv ntawm cov khoom siv hlau, uas yog tshwj xeeb tshaj yog tsim rau kev tsim cov hlau cam khwb cia siab.
high carbon silicon siv
- Steelmaking deoxidizer: Nws yog siv rau deoxidizing thiab txhim kho cov purity thiab toughness ntawm hlau;
- Casting carbonizer: siv los txhim kho carbon thiab silicon cov ntsiab lus hauv grey cam khwb cia hlau thiab hlau ductile;
- Alloy hloov pauv: hloov ib feem ntawm cov hlau-silicon alloys lossis carbon enhancers kom txo cov nqi.
Zuag qhia tag nrho, high-carbon silicon yog cov khoom siv tau zoo hauv cov hlau thiab cov khoom lag luam, pab txhim kho kev ua haujlwm ntawm cov txheej txheem smelting thiab cov khoom zoo thaum txo cov nqi tsim khoom.
