新日铁公司名古屋钢铁厂1982年1月11日公布,该厂不久前确立了在转炉精炼停止吹氧后,不用进行成分和温度的测定便可以立即出钢的“直接出钢技术”。这种直接出钢技术把过去的“转炉动态控制方法”又向前推进一步,是炼钢界划时代的技术,在提高生产能力和降低成本两方面都收到很大效果。通常转炉精炼停止吹氧时由于钢水温度和成分不一定正好在要求值上,因此精炼后钢水要在炉内保持2分钟以上进行测定,断定
The Nippon Steel Company, Nagoya Steel Works, announced on January 11, 1982 that the plant recently established a “direct tapping technology” that enables tapping immediately after the converter has stopped blowing oxygen and without the need to perform compositional and temperature measurements. This direct tapping technology takes the past “dynamic converter control method” one step further and is an epoch-making technology in the steelmaking industry. It has achieved great results in both increasing production capacity and reducing costs. Usually converter to stop blowing oxygen blowing temperature and composition of the molten steel is not necessarily the required value, so after refining the molten steel to be kept in the furnace for 2 minutes or more to determine, determine
