应用电解法与常压氯化法相结合的方法,成功地解决了含铬钢与碳含量高于0.5％的钢中非金属夹杂物的定量问题。简化了低压氯化法的设备与操作,并应用于滚珠钢中夹杂物的测定。对于在大气下电解的硫酸亚铁电解法的实用性,也进一步得到肯定。
By using the normal-pressure chlorine method in conjunction with the electrolytic method,the problem of the quantitative determination of non-metallic inclusions in low-chromium steelsand steels with carbon content more than 0.5％ was successfully solved. With the arrangementand procedures being simplified, the low-pressure chlorine method has also been found successfulin the determination of non-metallic inclusions in ball-bearing steel. The practicability of ferrous-sulfate electrolytic method has been further comfirmed.
