随着钢铁工业的不断发展,炼铁对入炉原料的质量要求越来越高。改善原料条件,提高入炉原料品位,是强化高炉生产的重要关键。烧结矿品位提高后,渣量相应减少了,这是高炉增产节焦的直接原因。同时由于减少了渣量,必然会改善高炉下部料柱透气性,使下部压差降低,有利于顺行;可以允许提高冶炼强度和加大喷吹量,使高炉生产得到进一步强化。据报道,入炉原料品位提高1%,焦比降低1.5%,高炉生产能力增加2.5%。据鞍 With the continuous development of the iron and steel industry, the quality of raw materials for ironmaking is getting higher and higher. Improve the raw material conditions, improve the quality of raw materials into the furnace, is to strengthen the production of blast furnace an important key. After the sinter grade is increased, the amount of slag is correspondingly reduced, which is the direct reason for increasing coke yield in the blast furnace. At the same time as reducing the amount of slag, will inevitably improve the lower part of the blast furnace gas permeability, so that the lower pressure drop is conducive to the line; can increase the intensity of smelting and increase the amount of injection, the blast furnace production has been further strengthened. It is reported that raw materials into the furnace increased by 1%, coke ratio decreased by 1.5%, blast furnace capacity increased by 2.5%. According to the saddle
