摘要
为了通过净化钢质,控制其夹杂物的形态,来提高管线钢的各项性能,对20管线钢稀土La变性硫化物夹杂进行了实验研究.实验结果表明,经稀土处理后的硫化物夹杂有多种产物形式,且形态发生改变,尺寸变小,对改善钢的性能非常有利.
The sulphide inclusion in the 20 steel modified by RE-element-La were researched, indicating several kinds of production after treating 20 steel with RE. The appearance of the sulphide inclusion changed already and its shape became smaller. These changes has brought a great deal of benefits to the capabilities of 20 steel.
