Cov txheej txheem melting tau sau tseg raws li hauv qab no

• xaiv raw cov ntaub ntawv xws li manganese ore, coke, limestone thiab lwm yam raw khoom thiab pre-kho lawv; them lub cub tawg nrog proportional batching thiab sib tov; yaj cov ntaub ntawv raw ntawm qhov kub thiab txias nyob rau hauv hluav taws xob arc rauv los yog blast furnaces, thiab hloov manganese oxides rau hauv manganese hlau nyob rau hauv ib tug txo qhov chaw los tsim alloys; kho cov alloy muaj pes tsawg leeg thiab desulfurize cov alloys; cais cov slag hlau thiab nrum cov molten alloys; thiab tom qab txias, cov alloys raug kuaj xyuas kom ua tau raws li cov qauv. Cov txheej txheem hais txog kev siv hluav taws xob thiab kev tiv thaiv ib puag ncig, suav nrog cov thev naus laus zis los txo cov pa phem thiab txhim kho kev ua haujlwm.
