利用浓差电池,对30t顶吹转炉冶炼的沸腾钢中含氧量进行了测定。测出了在吹炼终点、钢包和钢锭模中钢水的含氧量水平,确定了沸腾钢合适的含氧量,并得出了锰铁吸收率及焊条钢加铝量的经验公式,为控制沸腾钢的含氧量提供了依据。
Using the concentration of the battery, the oxygen content of the boiling steel smelting 30t top blown converter were measured. The oxygen content of molten steel in ladle and ingot mold was measured at the end of blowing, the suitable oxygen content of boiling steel was determined, and the empirical formula of ferromanganese absorption rate and adding amount of aluminum in welding rod was obtained Controlled boiling oxygen oxygen provides the basis.
