In order to increase the hot metal throughput of main trough, some reforms to the trough were carried out, and in order to realize zero-interval tapping and meet the needs for smooth operation and intensified smelting of BF, the management and maintenance of taphole were strengthened at Maanshan Steel's 2500 m~3 BF.

马钢2500m~3高炉通过对渣铁沟进行技术改造，增加了主沟通铁量；通过加强铁口管理与维护，实现了零间隔出铁，满足了高炉强化冶炼的需要。

The main reasons are: the reaction+=Fe+CO also occur during molten iron drop passing final slag, the slag has lowlevel of FeO ,but it still has strong decarburizing capability. In addition, during molten irondrop passing final slag, the dynamic conditions of decarburizing reaction is well, it makethe carbon content of liquid iron reduce.

主要是因为铁滴穿过终渣时也发生+=Fe+CO 反应，此时渣中含量虽少，脱碳反应的动力学条件很好，具有较强的脱碳能力。

Acidic aqueous ferric sulfate was abstained by heating maturating, dissolving and filtration process of mixture of pyrite cinders and sulfur acid.
