Khoom siv tshwj xeeb Ferro Silicon 70

Ferro silicon 70alloy thiab industrial silicon belongs rau silicon alloy hauv kev lag luam ferroalloy, uas yog dav siv hauv steelmaking, casting, non-ferrous hlau thiab lwm yam kev lag luam. Kev tsim cov 70 ferrosilicon alloy thiab cov khoom siv silicon yog raws li silica li raw khoom, uas yog tov nrog carbonaceous txo tus neeg sawv cev thiab ntxiv rau lub submerged arc rauv tom qab ntxuav, thiab ferrosilicon alloy thiab silicon hlau yog tau los ntawm carbonaceous txo nyob rau hauv kub kub. .

1.Hauv kev tsim khoom ntawm70 ferro siliconalloys thiab industrial silicon, thiaj li yuav ua kom cov huab cua permeability ntawm tus nqi, tus nqi yuav tsum nyob rau hauv ib tug tej yam particle loj ntau yam. Thaum lub sij hawm silica ore tu txheej txheem, silica ore nrog ib tug particle loj ntawm<20 will be screened to avoid entering the submerged arc furnace and affecting the air permeability of the charge. g in a waste of silicon ore resources, and at the same time increasing the production cost of 70% ferrosilicon alloy and industrial silicon.

2.Cov roj flue generated nyob rau hauv cov txheej txheem ntau lawm ntawm70 ferro siliconalloy thiab industrial silicon yog nplua nuj nyob rau hauv ib tug loj npaum li cas ntawm silica hmoov, uas yog sau los ntawm cov khoom siv tshem tawm plua plav kom tau silica hmoov nrog silica cov ntsiab lus ntawm 80 los yog 5%. Rau txhua 5t ntawm ferrosilicon tsim los ntawm ferroalloy nroj tsuag nyob rau hauv Tuam Tshoj, nws silica fume yuav raug tsim; Rau txhua 3t ntawm kev lag luam silicon tsim, nws microsilica fume yuav raug tsim. Raws li kev txheeb cais, Tuam Tshoj tus ferrosilicon tso zis nyob rau hauv 2012 yog 4.78 lab tons, thiab cov zis ntawm industrial silicon yog 1.13 lab tons. Raws li txoj cai, hauv 2012 ib leeg, Tuam Tshoj yuav tsim 1.33 lab tons ntawm silica fume.
