Dab tsi yog qhov sib txawv thiab kev sib txuas ntawm ferrosilicon thiab manganese silicon?

1. Ferrosilicon thiab manganese silicon yog cov hlau alloys siv tshaj plaws hauv cov txheej txheem steelmaking, thiab qhov sib txawv loj tshaj plaws yog thawj zaug yog cov khoom siv raw. Thib ob, kev siv cov khoom siv sib txawv, cov hlau silicon tsuas yog siv los ua cov deoxidizer, silicon manganese tib lub sijhawm muaj cov nyhuv deoxidation desulfurization, ntxiv rau, silicon manganese kuj tuaj yeem ua kom huv si ua kua. Thib peb, qhov kev faib tawm ntawm thaj chaw tsim khoom sib txawv, thaj chaw tsim khoom ferrosilicon feem ntau yog faib rau sab qaum teb sab hnub poob, qhov ntws los ntawm sab qaum teb mus rau sab qab teb sab hnub tuaj, Hebei, Liaoning, Jiangsu thiab lwm lub xeev tsim steel; Manganese silicon ntau lawm cheeb tsam yog faib nyob rau hauv sab qaum teb thiab sab qab teb, qhia ib tug qauv ntawm kev hloov ntawm sab qab teb mus rau sab qaum teb.

2. Tus nqi tsim nyog.

① Tus nqi sib xyaw ntawm ferrosilicon: ntau lawm ntawm 1 ton ntawm ferrosilicon=(1.8 tons ntawm silica +8000 KWH ntawm hluav taws xob +1 ton ntawm carbon +0.2 tons ntawm pellets) * 1.13 (VAT) + depreciation 50+ lwm 200.

② Manganese silicon nqi muaj pes tsawg leeg: ntau lawm 1 tuj manganese silicon=(2 tons manganese ore +0.75 tons manganese nplua nuj slag +0.26 tons silica +0.55 tons coke +4000 degrees hluav taws xob) *1.13 (tax) +50 (depreciation) +200 (lwm yam).

3. Nqe sib txawv ntawm ferrosilicon thiab manganese silicon.

① Los ntawm kev txheeb xyuas tus nqi piv txwv, piv txwv tias tus nqi hluav taws xob tuav txog 0.6 yuan / tuj, txog 1800 yuan / ton ntawm carbon, 850 yuan / ton ntawm manganese ore, thiab txog 1125 yuan / ton ntawm manganese nplua nuj slag, tus nqi ntawm ferrosilicon yog siab tshaj li ntawm 1000 yuan / tuj ntawm manganese silicon.

Yog li ntawd, los ntawm tus nqi sab, tus nqi sib txawv ntawm ferrosilicon thiab manganese silicon yuav tsum tau khaws cia ntawm li 1000 yuan, thiab nyob rau hauv cov ntaub ntawv ntawm me ntsis hloov nyob rau hauv lwm yam, tus nqi ntawm ferrosilicon yog siab tshaj manganese silicon rau lub sij hawm ntev. Cov ntaub ntawv saum toj no tsuas yog siv rau kev siv xwb thiab tsis yog tsim los ua ib qho lus qhia txog kev nqis peev
