Abstract

In the production of ultra-low carbon electrical steel, a significant increase in carbon content is observed after the introduction of alloying elements. One of the sources of carbon is ladle slag. This study describes the mechanism of carbon transfer from oxidizing slag to metal during the deoxidation of steel. A thermodynamic model of carbon solubility in basic oxidizing and reducing slags is proposed, considering the conditions of steelmaking in a converter and subsequent ladle treatment. The influence of ladle slag composition on carbon solubility is analyzed. Recommendations are developed to minimize the carburization of ultra-low carbon metal by slag-derived carbon.

超低碳电工钢在二次炼钢过程中的渗碳

在超低碳电工钢的生产中，引入合金元素后，其含碳量明显增加。碳的来源之一是钢包渣。本文研究了钢在脱氧过程中碳从氧化渣向金属转移的机理。考虑转炉炼钢和随后的钢包处理条件，提出了碱性氧化还原性炉渣中碳溶解度的热力学模型。分析了钢包渣成分对碳溶解度的影响。提出了建议，以尽量减少超低碳金属的炉渣衍生碳的渗碳。
