Tshuaj muaj pes tsawg leeg ntawm ferrosilicon

Ferrosiliconyog ib qho tseem ceeb ntawm cov khoom siv hlau, nrog rau ntau yam kev siv hauv steel, casting, metallurgy thiab lwm yam kev lag luam muaj lub luag haujlwm tseem ceeb heev. Cov tshuaj muaj pes tsawg leeg ntawm ferrosilicon feem ntau yog silicon thiab hlau, ntawm cov ntsiab lus ntawm silicon feem ntau yog ntau tshaj 70%, thiab cov ntsiab lus ntawm hlau yog li 20% mus rau 30%.

Ferrosilicon kuj muaj me me ntawm carbon, phosphorus, manganese, sulfur thiab lwm yam ntsiab lus, cov ntsiab lus ntawm cov ntsiab lus no muaj qee yam cuam tshuam rau kev ua haujlwm ntawm ferrosilicon. Piv txwv li, qhov siab dua cov ntsiab lus carbon, qhov siab dua lub zog thiab hardness ntawm ferrosilicon; Cov ntsiab lus ntawm phosphorus thiab manganese muaj qee yam cuam tshuam rau ductility thiab toughness ntawm ferrosilicon, thiab cov ntsiab lus ntawm sulfur kuj muaj qee yam cuam tshuam rau lub zog tensile thiab toughness ntawm ferrosilicon.

Ferrosilicon smelting

Ferrosiliconyog tsim los ntawm coke, steel chips, quartz (los yog silica) ua raw khoom, thiab yog refined los ntawm hluav taws xob rauv. Nyob rau hauv ib txwm refining ntawm ferrosilicon, silicon yog txo los ntawm silica uas muaj SI02. Smelting ferrosilicon feem ntau siv metallurgical coke li txo tus neeg sawv cev, thiab steel seem yog tus tswj hwm ntawm ferrosilicon.

Kev tsim tawm ntawm ib tuj ntawm ferrosilicon raw khoom thiab kev siv zog:

Silica:1780-1850kg

Coke:890-930kg

Hlau chips:220-230kg

Electrode muab tshuaj:45-55kg

Kev siv fais fab:8400-9000kw/t
