Kev suav ntawm cov khoom siv raw yuav tsum tsim 75 ferrosilicon:
(1) Tus nqi ntawm Silica
Ntxiv Tus nqi ntawm silicon nkag mus rau ferrosilicon los ntawm 100 kilograms ntawm silica yog:
100 × SiO2% × molecular hnyav Si / molecular hnyav SiO2 × silicon rov ua haujlwm.
Txij li cov ntsiab lus silica ntawm silica yog 98%, silicon rov qab tus nqi yog 92%. Hloov hauv cov qauv saum toj no:
100 × 98% × 28/60 × 92% =42kg
Ntawd yog, tus nqi ntawm silicon nkag mus rau ferrosilicon thaum smelting 75 ferrosilicon ntawm 100 kilograms ntawm silica yog 42 kilograms.
Los ntawm 75 ferrosilicon, nws muaj peev xwm smelt:
42 ÷ 75%=56 kg.
Hauv lwm lo lus, txhawm rau smelt 56 kilograms ntawm 75 ferrosilicon, 100 kilograms ntawm silica thiab cov nqi sib xws ntawm coke thiab steel khib nyiab yog xav tau.
Tus nqi ntawm silica yuav tsum tau tsim ib tuj ntawm 75 ferrosilicon yog:
100/56 × 1000=1786≈1800kg
(2) Tus nqi ntawm Coke thiab Steel Chips
Ntxiv Rau 100 kilograms ntawm silica, 54 kilograms ntawm coke thiab 13.6 kilograms ntawm steel chips yuav tsum tau. Tus nqi ntawm coke yuav tsum tau tsim ib tuj ntawm 75 ferrosilicon yog:
1800 × 54 / {2}} kg.
Qhov xav tau ntawm steel chips yog:
1800 × 13.6 / 100=238≈240kg
Cov kev suav saum toj no qhia tau hais tias kwv yees li 1,800 kilograms ntawm silica, 990 kilograms ntawm coke, thiab 240 kilograms ntawm scraps ntawm hlau yuav tsum tau smelt ib tuj ntawm 75% ferrosilicon.
