炼钢过程中非金属夹杂物的形成是不可避免的，如果控制不当，可能会导致性能和生产问题。炉渣是可用于进行这种控制的资源之一。在炼钢过程中，一般认为，当浮选充分时，夹杂物自然被炉渣吸收。然而，分离和溶解可能决定渣的夹杂物吸收能力。本文的讨论解释了钢/夹杂物界面分离与接触角之间的关系，从而区分了液体和固体夹杂物的分离机制。虽然液体颗粒在实验观察中表现出更可预测的行为，但为了描述固体颗粒的去除，热力学分析是必要的。在其他研究结果中，很明显，渣粘度和夹杂物/渣界面处化合物的形成强烈影响夹杂物溶解能力。在文献中的调查结果的详细描述，这篇评论认为最有影响力的因素，以帮助优化渣夹杂物吸收。
The formation of non-metallic inclusions during steelmaking is inevitable and, when not properly controlled, can cause performance and production problems. Slag is one of the resources available to carry out this control. In steelmaking, it is generally understood that inclusions are naturally absorbed by slag when flotation is sufficient. However, separation and dissolution may define the inclusion absorption capacity of slag. The discussion in this review explains the relationship between separation and the contact angle at the steel/inclusion interface, which differentiates the mechanism from liquid and solid inclusions. Whereas liquid particles show more predictable behavior in experimental observations, thermodynamic analysis is necessary in order to describe the removal of solid particles. Among other findings, it is evident that slag viscosity and the formation of compounds at the inclusion/slag interface strongly influence inclusion dissolution capacity. Following a detailed description of findings in the literature, this review considers the most influential factors to aid in optimizing slags for inclusion absorption.
