1.概要 随着钢铁材料向新领域发展,对耐加工细钢线、薄板的质量要求逐渐严格。为此,不仅要净化钢水,而且,在轧制过程中,还必须控制住不妨碍加工的延性夹杂物形态。日本京浜钢铁厂采用二次精炼设备,控制熔渣成份,以此来达到上述要求。现将控制夹杂物形态技术介绍如下。 1. Outline With the development of steel materials in new fields, the quality requirements of thin steel plates and thin plates are becoming increasingly stringent. To this end, not only to clean the molten steel, but also in the rolling process, but also must be controlled without affecting the processing of ductile inclusions morphology. Japan Keihin Iron and Steel Plant with secondary refining equipment, slag control components, in order to achieve the above requirements. Now control the inclusion of morphological techniques are described below.
