Stainless steelmaking produces different types of slags which need to be cooled, stored, and pretreated before further use. In current practice, the slag is cooled in an air atmosphere, but water cooling has been envisaged to speed up cooling. The aim of this article is to simulate the cooling of argon‐oxygen decarburization (AOD) slag under the conditions of ambient cooling and water cooling. The effects of the thickness and initial temperature of the slag layer are also studied. Finally, practical means to improve the cooling practice are evaluated based on the model predictions.

氩氧脱碳炉渣冷却的数值模拟

不锈钢冶炼产生不同类型的炉渣,需要进一步冷却,储存和预处理。在当前实践中,炉渣在空气气氛中冷却,但是已经设想了水冷却以加速冷却。本文的目的是模拟在环境冷却和水冷条件下氩氧脱碳(AOD)炉渣的冷却。还研究了渣层厚度和初始温度的影响。最后,根据模型预测评估改进冷却实践的实用方法。
