摘要

确定了循环真空处理过程中熔体除碳的主要机理。研究表明，在金属加工的初始阶段，脱碳的主要机制是熔体中CO气泡的形成。随着碳浓度的降低，主要机理转变为注气除碳。为了实现低碳浓度（低于0.002%），有必要加强除碳机制，减少炼钢装置炉衬的溶碳量。

Dominant mechanisms of melt decarburization in a circulation vacuum degasser leading to rational technological solutions for decreasing carbon content in steel below 0.002%

The main mechanisms of carbon removal from the melt during circulation vacuum treatment have been identified. It has been shown that, at the initial stage of metal processing, the primary mechanism of decarburization is the formation of CO gas bubbles within the melt. As the carbon concentration decreases, the dominant mechanism shifts to carbon removal through gas injection. To achieve low carbon concentrations (below 0.002%), it is necessary to intensify the mechanisms of carbon removal and reduce the amount of carbon dissolving carbon from the lining of the steelmaking unit.
