Is Nrias teb tus nqi FOB ntawm silicon manganese thaum Lub Peb Hlis 1

Silicon manganese yog ib qho alloy uas muaj manganese, silicon, thiab hlau. Nws yog siv rau hauv kev tsim cov hlau los txhim kho nws cov khoom, xws li lub zog, hardness, thiab tsis kam mus rau corrosion. Kev tsim cov silicon manganese feem ntau suav nrog cov kauj ruam hauv qab no:

Mining thiab tau txais txiaj ntsig ntawm manganese ores: Thawj kauj ruam hauv kev tsim silicon manganese yog kev rho tawm ntawm manganese los ntawm nws cov ore. Manganese ores feem ntau yog mined los ntawm qhib-qhov mines los yog underground mines thiab ces ua kom tshem tawm impurities.

Smelting: Cov manganese ore yog ces smelted nyob rau hauv lub cub tawg nrog silicon thiab hlau los tsim silicon manganese alloy. Cov txheej txheem smelting suav nrog cua sov cov ore thiab txo nws nrog tus neeg sawv cev txo qis, xws li coke, kom tshem tawm cov hlau.

Refining: Cov silicon manganese alloy yog tom qab ntawd ua kom zoo kom tshem tawm cov impurities thiab kho nws cov muaj pes tsawg leeg kom tau raws li cov kev cai tshwj xeeb.

Casting: Cov kauj ruam kawg hauv kev tsim cov silicon manganese yog cov hlau casting rau hauv cov duab uas xav tau, xws li ingots, slabs, lossis billets.
