摘要
对ER50-G生产过程中夹杂物的形成和演变规律进行了研究。结果表明，在使用铝铁脱氧后，钢水中生成大量Al2O3夹杂物，随后向镁、钙铝酸盐类夹杂物转变，并多数在精炼过程中上浮去除；RH处理中加入钛铁后，钢水中生成TiO2和TiN，其中TiO2或上浮去除或逐渐被铝还原，在后道工序中很难再被发现；而TiN则随氮含量的升高而增多，并保留至盘条中。
The formation and evolution of inclusions in ER50- G steel was studied. The results showed that a large amount of alumina inclusions forming after ferroaluminum deoxidation transformed to magnesium aluminate and calcium aluminate inclusions, most of which have been removed in the following refining process. Titanium oxides and titanium nitrides formed after ferrotitanium had been charged into hot metal during RH process. Titanium oxides have been removed or reduced by aluminum, thus could be hardly found in later procedures. The amount of titanium nitride increased with the increase of nitrogen content and retained in ER50-G wire rod.
