一、前言硫化物是钢中的主要夹杂物之一、它的组成、形态、大小、分布情况和数量对钢材性能有很大的影响、我国这方面研究尚少,特别是连铸坯更少,为此我们对武钢和上钢连铸板坯中硫化物的情况作了调查,并从钢的化学成分、脱氧程度和凝固组织方面、对硫化物的形态、数量、分布情况等作了初步探讨,希望能为今后提高连铸坯质量提供一些依据。 I. Preface Sulfide is one of the main inclusions in steel. Its composition, shape, size, distribution and quantity have a great influence on the properties of steel. In our country, there is still little research on it, especially for the billets For this reason, we investigated the situation of sulfide in WISCO and Shangang continuous casting slabs and made preliminary preliminary studies on the morphology, quantity and distribution of sulfide from the aspects of chemical composition, degree of deoxidation and solidified structure of steel Explore and hope to provide some basis for improving the quality of continuous casting billet in the future.
