摘要
根据试验结果分析了几种评价钢洁净度方法的特点,指出了各种方法的适用范围。建议不同工艺、不同品种需结合几种方法来评价钢的洁净度,对超低碳钢的洁净度评价应采用分析铸坯表面簇状夹杂物的方法。随着精炼技术的进步,钢中内生夹杂物的减少,应研究更适合的检测评价钢洁净度的方法。
Based on the experimental results characteristics of various evaluation methods are analyzed and application scope of every method is determined. It is recommended that several different methods have to be appropriately selected to evaluate the cleanliness of steel in light of the different process and different steel grade. For evaluation on the cleanliness of the super low carbon steel the appropriate method is to analyze the cluster shaped inclusions over the surface of the slab. With the development of refining technologies inclusions of steel come to be less than before, thus better evaluation methods should be developed for evaluating cleanliness of steel.
