【摘要】 经过对安钢4号高炉进行热平衡测试,计算出4号高炉的最低理论焦比为420kg/t铁。经过分析,提出了进一步节能降耗的方向:提高矿石品位、改善烧结矿的还原性、实行焦炭整粒、提高风温、改善冷却水质量、富氧喷吹煤粉、改进高炉操作、不加或少加废铁等。更多还原

【Abstract】 The theoretical lowest coke ratio of 420kg/tFe at No4 BF of Anyang Iron & Steel Co.was calculated according to the heat balance measurement result.To further reduce energy consumption,such measures could be adopted:raising the ore grade,improving the reductibility of sinter,carrying out the size preparation of coke,increasing the blast temperature,improving the quality of cooling water,injecting pulverized coal with oxygen-enriched blast and so on.更多还原
