Silicon Barium yog cov khoom siv hlau siv hauv kev lag luam metallurgical, feem ntau yog tsim los ntawm cov khoom silicon (Si) thiab barium (Ba). Nws feem ntau yog siv rau hauv cov txheej txheem hlau thiab hlau smelting, nrog rau qee yam deoxidizing thiab alloying teebmeem, thiab nws txoj kev siv tseem ceeb yog los txhim kho cov hlau thiab hlau zoo, tshwj xeeb tshaj yog hauv kev txhim kho cov hlau thiab txo cov ntsiab lus ntawm impurities xws li sulfur thiab phosphorus.
silicon barium siv lub ntsiab
1. Hlau smelting
- Deoxidizer: Silicon barium feem ntau yog siv los ua deoxidizer hauv steel smelting. Ntxiv barium silica rau hlau tuaj yeem tshem tawm cov pa oxygen hauv cov hlau zoo, yog li txo cov qib ntawm oxidation ntawm hlau thiab txhim kho cov hlau zoo.
- Alloying element: Raws li cov khoom siv alloying, barium silicate tuaj yeem txhim kho lub zog, toughness thiab corrosion kuj ntawm steel, tshwj xeeb tshaj yog nyob rau hauv zus tau tej cov uas tsis muaj sulfur, tsawg-phosphorus hlau, nws muaj peev xwm tswj tau cov impurity ntsiab nyob rau hauv steel.
2. Founding kev lag luam
Silicon barium kuj tau siv dav hauv kev lag luam hauv kev lag luam, tshwj xeeb tshaj yog nyob rau hauv kev tsim tshwj xeeb cam khwb cia hlau. Nws pab txo cov kab nrib pleb thiab porosity hauv castings, kom ntseeg tau tias casting zoo thiab ruaj khov.
3. Metallurgical decontamination
Silicon barium tuaj yeem tshem tawm cov teeb meem tsis zoo uas tsim tawm thaum lub sij hawm smelting txheej txheem, tshwj xeeb tshaj yog nyob rau hauv high-kub smelting ib puag ncig, qhov twg nws cov tshuaj muaj zog ua rau nws tsim cov tebchaw nrog cov ntsiab lus xws li sulfur thiab phosphorus, uas precipitate tawm ntawm cov hlau.
Cov yam ntxwv ntawm silicon barium
1. Deoxygenation thiab impurity tshem tawm cov khoom
Silicon barium tuaj yeem tshem tawm cov pa oxygen, sulfur, phosphorus thiab lwm yam impurities hauv cov hlau, txhim kho cov purity thiab kev ua tau zoo ntawm cov hlau, tshwj xeeb tshaj yog tsim rau kev tsim cov hlau xav tau.
2. Txhim kho kev ua haujlwm ntawm cov hlau
Raws li cov khoom siv ntxiv, barium silicate tuaj yeem txhim kho lub zog ntawm cov hlau, txhim kho nws lub zog, hardness, hnav tsis kam, thiab lwm yam.
3. Kub stability
Silicon barium muaj qhov kub siab ruaj khov hauv cov txheej txheem smelting, tuaj yeem hloov mus rau qhov kub thiab txias ib puag ncig, thiab muaj zog antioxidant zog kom txo tau qhov tshwm sim ntawm qhov tshwm sim tsis zoo.
4. Kev txhim kho ntawm cov hlau huv
Silicon barium tuaj yeem txo cov kev suav nrog hauv cov hlau thiab txhim kho kev huv ntawm cov hlau, uas yog tsim rau precision casting thiab tsim cov hlau zoo.
silicon barium zoo
- Kev txuag nqi: Piv nrog rau lwm cov deoxidizers, barium silica yog tus nqi qis dua, tab sis tseem muab cov deoxidation zoo thiab tshem tawm cov kev suav nrog.
- Txhim kho kev ua haujlwm zoo: Nws tuaj yeem txhim kho qhov ua tau zoo ntawm cov txheej txheem smelting thiab txo cov sijhawm ua haujlwm thiab cov peev txheej pov tseg.
- Ib puag ncig tus phooj ywg: Siv barium silicate ua cov khoom siv alloy thiab deoxidizer pab txo qis cov pa phem thiab cov pa phem ib puag ncig.
Silicon barium yog ib qho tseem ceeb metallurgical alloy khoom, dav siv nyob rau hauv hlau thiab hlau smelting thiab casting industries. Nws zoo heev deoxidation, impurity tshem tawm thiab alloying zog ua rau nws tuav ib tug tseem ceeb txoj hauj lwm nyob rau hauv hlau thiab steel ntau lawm, tshwj xeeb tshaj yog nyob rau hauv cov txheej txheem ntawm high-zoo steel muaj lub luag hauj lwm irreplaceable.
