一、前言 钢铁工业能耗占我国总能耗的15—16％。高炉炼铁,占钢铁联合企业总能耗的70—80％。其中太部分是高炉燃料。 降低高炉燃料比是高炉操作技术的最高目标。本公司为了降低燃料比,广泛比较择用有关新技术,改善原料性质,控制炉料分布,稳定炉况操作制度,实现了高炉的低燃料比操作。千叶6号高炉大幅度降低燃料比就是一例。以下介绍该炉概况。
I. INTRODUCTION The steel industry consumes 15-16% of the total energy consumption in China. Blast furnace ironmaking, accounting for 70-80% of the total energy consumption of iron and steel complexes. Most of them are blast furnace fuel. Lowering the blast furnace fuel ratio is the highest goal of blast furnace operating technology. In order to reduce the fuel ratio, the Company extensively compares and selects the relevant new technologies, improves the properties of raw materials, controls the distribution of charge and stabilizes the operating conditions of the furnace, and realizes the low-fuel ratio operation of the blast furnace. Chiba No. 6 blast furnace significantly reduce the fuel ratio is an example. The following description of the furnace.
