摘要

在实验室用碳管炉研究了含0.048%0.065%硫的中碳钢(%:0.46~0.57C

0.83~0.94Mn

0.21~0.24Cr

0.03~0.04Mo)钙处理时

加入Ca-Si和FeS先后顺序以及钢中Ca/S值对该钢硫化物形态和数量的影响。结果表明

先加FeS后加Ca-Si处理时

钢中硫化物的长度与数量均较先加Ca-Si后加FeS处理时有明显降低。随钢中Ca/S值增加

钢中颗粒状复合夹杂物的数量增加

同时长条状的塑性硫化物夹杂数量减少

但尺寸增大。采用Ca-Si复合处理时

钢中合理的Ca/S值约为0.03。

Abstract

The effect of Ca-Si and FeS adding order in Ca-treatment process and Ca/S ratio for steel on morphology and quality of sulphide in 0.048%～0.065% S medium-carbon steel(0.46～0.57C

0.83～0.94Mn

0.21～0.24Cr

0.03~0.04Mo)has been studied by a carbon tube fumnace in laboratory.the results showed that the length and quantity of sulphide in steel by treatment first adding FeS then adding Ca-Si were obviously lower than that first adding Ca-Si then adding FeS;and with increasing Ca/S ratio in steel

the quantity of spherical multi-phase inclusions increased while the quantity of strip-shapc MnS decreased

of which the size increased. The available Ca/S ratio for steel by compound treatment using Ca-Si is ～0.03.
