一、绪言一般用于厚板,热轧钢板的连铸,为了保证质量和操作顺利,均以镇静钢为前提。但是随着过剩脫氧,合金单耗增加,从而导致浸渍水口堵塞给连铸造成障碍。日本新日铁畑厂针对这些问题从事连铸热轧钢材弱脱氧化的研究,建立了新钢种的制造技术。 First, the introduction is generally used for thick slab, hot-rolled steel continuous casting, in order to ensure the quality and smooth operation, are based on the prerequisite to calm the steel. However, with excessive deoxidation, the unit consumption of the alloy increases, resulting in obstruction to the continuous casting due to blockage of the immersion nozzle. Japan’s Nippon Steel Works in response to these issues in the hot-rolled continuous casting of weak deoxidation research, the establishment of a new type of steel manufacturing technology.
