1.前言 高炉渣的出炉温度通常在1400℃以上,其含热相当于58kg标煤/t渣。高炉渣带走的显热在高炉热平衡中约占10％左右,即占钢铁工业总能耗的4％左右。 我国年产高炉渣约2200×10~4t,其含热相当于128×10~4t标煤。目前大部分高炉渣冲成水渣制作矿渣水泥,全国1/3的水泥产量是以水冲高炉渣为原料生产的。水冲渣时炉渣的显热转为40～60℃的热水,北
1. Introduction Blast furnace slag temperature is usually above 1400 ℃, its heat is equivalent to 58kg standard coal / t slag. The sensible heat taken by blast furnace slag accounts for about 10% of the blast furnace thermal balance, which accounts for about 4% of the total energy consumption of the steel industry. China’s annual output of blast furnace slag is about 2200 × 10 ~ 4t, and its heat content is equivalent to 128 × 10 ~ 4t standard coal. At present, most of the blast furnace slag is washed into slag to make slag cement, and 1/3 of the country’s cement output is produced by using blast furnace slag as raw material. Slag slag water when the sensible heat transferred to 40 ~ 60 ℃ hot water, north
