Tsawg carbon ferromanganese ua txoj kev
Muaj ob txoj hauv kev tseem ceeb rau kev ua cov pa roj carbon tsawg ferromanganese: blast furnace method thiab hluav taws xob rauv txoj kev.
Txoj kev blast furnace yog smelted nyob rau hauv high-kub moj tej tawg rauv thiab mas smelts manganese los ntawm tsawg-carbon ferromanganese. Feem ntau, nws tsim nyog thaum cov ntsiab lus manganese nce mus txog 45-65%.
Txoj kev siv hluav taws xob siv hluav taws xob siv hluav taws xob hloov mus rau hauv lub zog hluav taws xob kom smelt ferromanganese, hlau ore thiab lwm yam khoom siv raw rau hauv cov pa roj carbon tsawg ferromanganese.
Ob txoj kev yuav tsum tau pretreatment ntawm raw cov ntaub ntawv, xws li crushing, sib tsoo, sib nqus sib cais thiab lwm yam kauj ruam kom tshem tawm impurities thiab txhim kho qhov zoo ntawm ZhenAn Tshiab Khoom ferromanganese.
Cov txheej txheem tshwj xeeb tuaj yeem muab faib ua cov kauj ruam xws li batching, furnace loading, smelting, slag tshem tawm, muaj pes tsawg leeg kho thiab casting.
Cov yam ntxwv ntawm qis carbon ferromanganese
1. Cov ntsiab lus carbon tsawg
Cov ntsiab lus ntawm cov pa roj carbon tsawg ferromanganese feem ntau yog qis dua 1.0%, thiab qee lub npe tuaj yeem ua tiav hauv qab 0.4%. Cov ntsiab lus qis dua ua rau cov hlau tsis huv, txo cov impurities hauv cov hlau, thiab txhim kho cov khoom siv tshuab thiab corrosion kuj.
2. Cov ntsiab lus siab manganese
Cov ntsiab lus ntawm manganese ntawm qis carbon ferromanganese feem ntau yog nyob nruab nrab ntawm 65-90%, thiab manganese yog cov ntsiab lus alloying hauv cov hlau. Manganese muaj kev tiv thaiv zoo corrosion thiab kub tsis kam, tuaj yeem txhim kho hardness thiab toughness ntawm alloy, thiab ua rau kom hnav tsis kam thiab kub tsis kam. Cov ntsiab lus siab manganese ua rau qis carbon ferromanganese cov khoom siv zoo tagnrho.
3. Kev ua haujlwm kub zoo
Tsawg carbon ferromanganese muaj cua sov zoo dua vim nws cov ntsiab lus ntau dua manganese. Nws tuaj yeem tswj xyuas cov khoom zoo thiab lub cev nyob rau hauv qhov kub thiab txias, tsis yooj yim rau yaj thiab deform, thiab tsim nyog rau kev siv nyob rau hauv qhov kub thiab txias ua haujlwm.
