Abstract

The paper shows the results of a study of the influence of the cut-off method of the slag by using destructible plugs on the quantitative indicators of the redistribution of slag and metal in the steel ladle during the metal tapping operation from the converter. The laboratory setup simulates a real 160-ton industrial top-blown oxygen converter, and a steel ladle at a scale of 1:18 has been used to fulfill the study. Water was chosen as a liquid steel imitator, and machine oil was chosen for slag with parameters that ensure the similarity of physical parameters in the metal-slag system. The physical modelling of the tapping process of a two-phase converter bath in the case of a destructible plug in the tap hole compared to the tapping option without it showed a significant positive effect of the presence of the plug in the initial period from the moment the converter is tilted.

碱性氧炉金属出丝特征的两相低温模型研究

本文介绍了在转炉出钢过程中，用可破坏塞堵截渣方法对钢包内渣和金属再分布定量指标影响的研究结果。实验装置模拟了一个真实的160吨工业顶吹氧转炉，并使用了一个1:18比例的钢包来完成研究。钢液模拟剂选用水，渣液模拟剂选用机油，参数保证金属-渣体系物理参数的相似性。对两相转炉熔池在有可破坏塞的情况下的攻丝过程进行了物理建模，与没有可破坏塞的攻丝相比，结果表明，从转炉倾斜的那一刻起，在初始阶段有塞的存在会产生显著的积极影响。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
