摘要
肥气煤在700~800℃的温度下煅烧后,用于矿热炉中还原碱土合金,并且可以代替木炭(木块)、石油焦、冶金焦等价格昂贵的炭素材料,尤其是在混合加料法中,由于活性碳多,比电阻大,延长了冶炼周期,提高了产量,降低了电耗.
Reducing alkaline alloy in a ore smelting electric are furnace with calcined fat gas coal at the temperature 700 - 800℃) can replace expensive carbon materials such as charcoal (or pieces of wood)、 petroleum coke, metallurgy coke etc., and can prolong smelting period, increase output and reduce electricity consumption because of more activated carbon, higher specific resistivity, especially with mixed charging process.
