二次精炼技术(With the advent of secondary refining techniques and the drive toward steels of significantly improved properties and quality, the tundish has become a tertiary refiner. 随着二次精炼技术的出现和大幅度提高钢的性能和质量的推动,中间包已变成了三次精炼器。)
【钢】 溅渣护炉技术(【技】转炉出钢后用高速氮气射流冲击残留在转炉内的高熔点炉渣,使之溅起并附着在转炉炉衬表面形成保护层,以提高炉衬寿命的一种技术。: Slag splashing technique has been used successfully in many basic oxygen furnaces (BOFs) to enhance the campaign life. 为了提高炉龄,许多氧气顶吹转炉现已成功使用了溅渣护炉技术。)
表面处理技术(One of the latest surface treatment techniques is laser surface hardening which has the big advantage that selected areas can be hardened without treating the whole part. 激光表面硬化是最新发明的表面处理技术之一。其最大优点是不必对整个部件,而只对所选定的区域进行硬化处理。)
