Kev suav cov ntaub ntawv raw xav tau rau 45 ferrosilicon:
(1) Tus nqi ntawm silica ntxiv
Cov nyiaj silica ntxiv ntawm 45 ferrosilicon yog qhov tseem ceeb tib yam li txoj kev suav ntawm 75 ferrosilicon, tshwj tsis yog tias silicon rov qab tus nqi yog xam li 96%.
Tus nqi ntawm silicon nkag mus rau ferrosilicon los ntawm 100 kilograms ntawm silica yog:
100 × 98% × 28/60 × 96% =43.7 kg
Tus nqi ntawm 45% ferrosilicon uas tuaj yeem smelted:
43.7 ÷ 45% =97kg
silica xav tau rau ib tuj ntawm 45 ferrosilicon yog:
100/97 × 1000=1040kg
(2) Ntxiv cov coke thiab steel chips
100 kg ntawm silica yuav tsum tau 52 kg ntawm coke thiab 54 kg ntawm steel chips (saib nplooj 25)
Tus nqi ntawm coke xav tau rau ib tuj ntawm 45 ferrosilicon yog
1040 × 52 / {2}}kg
Tus nqi ntawm steel chips yog:
1040 × 54 / {2}}kg
Cov kev suav saum toj no qhia tau hais tias smelting ib tuj ntawm 45 ferrosilicon yuav tsum tau 1040 kilograms ntawm silica, 550 kilograms ntawm coke, thiab 560 kilograms ntawm steel scraps.
