Description

22,4 -i- а5,б ,- , . , ,1. Экономическа  э(рфективность предлагаемого способа заключаетс  в выводе кокса из доменной шихты, повышенной интенсивностью плавки, св занной с выводом азота из состава печных газов, получением малоуглеродистого металла, исключением воздухонагревателей из состава оборудовани  доменных цехов.22.4 -i-a5, b, -,. , ,one. Economic efficiency (the efficiency of the proposed method consists in removing coke from the blast furnace charge, increased melting rate associated with the removal of nitrogen from the furnace gases, obtaining a low-carbon metal, excluding air heaters from the equipment of the blast furnaces.
