Steelmaking yog kom tau cov hlau nrog ntau zog, hardness, toughness, corrosion kuj thiab lwm yam khoom.
Txhawm rau kom tau txais cov hlau nrog qee cov yam ntxwv, peb yuav tsum siv txoj kev sib txawv thiab ntxiv cov khoom siv hlau sib txawv kom tau txais hom hlau uas peb xav tau.
Cov txheej txheem tseem ceeb los txhim kho kev ua haujlwm ntawm cov hlau muaj xws li
1. Alloying: Ntxiv ib qho kev faib ua feem ntawm alloying ntsiab rau hlau, xws li manganese, chromium, vanadium, thiab lwm yam, cov ntsiab lus no tuaj yeem tsim cov tebchaw tshiab nrog hlau, yog li txhim kho lub zog thiab hardness ntawm hlau.
2. Kev kho cua sov: hloov cov qauv thiab cov khoom ntawm cov hlau los ntawm cua sov thiab cua txias, yog li txhim kho lub zog thiab hardness ntawm hlau. Feem ntau siv cov kev kho cua sov xws li quenching, tempering, quenching thiab tempering, thiab lwm yam.
3. Kev ua haujlwm txias: Los ntawm txias dov, txias forging thiab lwm txoj kev, cov hlau tsim elastic deformation zog thaum lub sij hawm yas deformation txheej txheem thiab hloov mus rau hauv lattice distortion zog, yog li txhim kho lub zog thiab hardness ntawm cov hlau.
4. Kev kho deg hardening: Txhim kho qhov tawv tawv los ntawm kev hloov cov tshuaj muaj pes tsawg leeg thiab microstructure ntawm cov hlau nto. Feem ntau siv txoj kev kho deg hardening xws li carburizing, nitriding, boronizing, thiab lwm yam.
5. Refining: Los ntawm refining technology, impurity ntsiab nyob rau hauv steel raug tshem tawm, lub purity ntawm steel yog zoo dua, thiab kev ua tau zoo ntawm steel yog zoo dua.
Dab tsi yog lub luag haujlwm 75 ferrosilicon ua si hauv steelmaking?
75 Ferrosilicon plays lub luag haujlwm ntawm deoxidizer hauv steelmaking.
Thaum lub sij hawm steelmaking txheej txheem, 75% ferrosilicon yog ntxiv rau cov hlau molten thiab melted ntawm qhov kub thiab txias kom siab react nrog cov hlau molten, zoo tshem oxygen los ntawm cov hlau molten thiab txhim kho cov purity thiab zoo ntawm cov hlau. Piv nrog rau lwm yam steelmaking additives, 75 ferrosilicon muaj qhov zoo ntawm cov nyhuv deoxidation siab, siab alloying kev ua tau zoo thiab ib puag ncig tus phooj ywg.
Nyob rau tib lub sijhawm, 75 ferrosilicon kuj tuaj yeem siv los ua cov khoom siv alloying ntxiv los txhim kho cov khoom ntawm cov hlau.
