Abstract
The chemical and phase compositions of rolling scale of low-carbon sheet steel at the Izhora Plant are studied experimentally. The results are compared to the data of the scale studies at various metallurgical enterprises reported by other authors. It is shown that the main chemical elements in the scale composition in all the cases are Fe and O plus some Mn, Cr, Al, Ca, and C. The phase compositions of the scale are also similar and contain hematite, magnetite, and wustite. However, the proportion of the phases over cross-section of the scale varies significantly and depends on the oxidation conditions. It is inferred that in order to reuse the scale in steelmaking, its preliminary study is required in each specific case.
实验研究了伊兹霍拉工厂低碳薄钢板轧制鳞片的化学成分和相组成。研究结果与其他作者报告的不同冶金企业的轧制鳞片研究数据进行了比较。结果表明，在所有情况下，轧制鳞片成分中的主要化学元素都是铁和 O 外加一些锰、铬、铝、钙和 C。不过，这些相在鳞片横截面上的比例差异很大，并取决于氧化条件。据此推断，为了在炼钢过程中重新利用鳞片，需要对每种具体情况进行初步研究。
