国内外高炉冶炼的实践证明,富氧鼓风可以强化高炉冶炼,大大提高高炉的生产能力,增加燃料喷吹量。根据我国的资源情况,采用富氧鼓风结合大量喷吹煤粉,是大量增产生铁的一项有力措施。初步计算表明,采用富氧鼓风比新建高炉节约投资和能源。建议安排适当高炉进行高浓度富氧鼓风的冶炼试验。
Blast furnace smelting practice at home and abroad proved that oxygen-enriched blast furnace can enhance blast furnace smelting, greatly enhance the production capacity of the blast furnace to increase the amount of fuel injection. According to China’s resources, the use of oxygen-enriched blast furnace with a large number of pulverized coal injection is a substantial increase in pig iron production is a powerful measure. Preliminary calculations show that the use of oxygen-enriched blast furnace to save investment and energy than the new blast furnace. It is advisable to arrange an appropriate blast furnace for high-concentration oxygen-enriched blast furnace smelting tests.
