Cov pa roj carbon ntau ferromanganese tuaj yeem siv los ua cov khoom siv alloy hauv cov txheej txheem steelmaking. Nws lub luag haujlwm tseem ceeb yog txhawm rau nce cov ntsiab lus ntawm manganese hauv cov hlau molten, txhawb cov carburization hauv cov hlau molten, thiab sib npaug faib cov ntsiab lus carbon hauv cov hlau molten, yog li txhim kho cov hlau zoo thiab txhim kho cov hlau zoo. mechanical zog thiab corrosion kuj.
Nyob rau tib lub sijhawm, cov pa roj carbon ferromanganese siab kuj tseem tuaj yeem tshem tawm cov khoom tsim tawm thaum lub sijhawm ua cov txheej txheem steel thiab txhim kho qhov zoo ntawm cov hlau molten.
Dab tsi yog lub luag haujlwm siab carbon ferromanganese ua si hauv steelmaking?
Nws daim ntawv thov nyob rau hauv steelmaking yog feem ntau xav txog nyob rau hauv cov nram qab no yam:
1. Txhim kho lub purity ntawm molten hlau
Cov khoom manganese nyob rau hauv siab carbon ferromanganese tuaj yeem txo cov pa oxygen hauv cov hlau molten, yog li txo cov ntsiab lus oxide hauv cov hlau molten thiab txhim kho cov purity ntawm molten steel.
2. Ua kom lub zog thiab hardness ntawm cov hlau
Cov pa roj carbon monoxide nyob rau hauv high-carbon ferromanganese tuaj yeem txhim kho lub zog thiab hardness ntawm hlau, thaum lub ntsiab manganese tuaj yeem txhim kho lub zog thiab hardness ntawm hlau.
3. Txhim kho corrosion kuj ntawm hlau
Cov khoom manganese nyob rau hauv siab carbon ferromanganese tuaj yeem txhim kho corrosion kuj ntawm steel, tshwj xeeb tshaj yog cov corrosion kuj ntawm acids xws li sulfuric acid thiab nitric acid.
4. Txhim kho qhov kev ua tau zoo ntawm cov hlau
Cov khoom manganese nyob rau hauv siab carbon ferromanganese tuaj yeem txhim kho cov khoom zoo ntawm cov hlau, nrog rau cov tawv tawv, qaug zog, thiab lwm yam.
