河北联合大学轻工学院 QINGGONG COLLEGE, HEBEI UNITED UNIVERSITY 毕业论文 论文题目：国丰Q195钢工艺研究 学生姓名： 学 号：200815 专业班级：08冶金 学 部：材料化工部 指导教师：王硕明 教授 2012年05月2日 摘 要 唐山国丰钢铁有限公司成立于1993年，是一家集制氧、烧结、炼铁、炼钢、轧钢为一体的大型钢铁联合企业，具备年产铁、钢、材各800万吨的综合生产能力。。为了进一步提高技术水平、增加品种、提高产品附加值、稳定产品质量，河北联合大学与国丰公司商定，广泛进行技术合作，充分发挥学校和企业在理论研究、技术开发和生产经营等方面的各自优势，对国丰所冶炼的典型钢种Q195进行系统研究，明确国丰生产水平与国际、国内先进钢厂相比所处的相对地位，以明了存在的差距和进一步提高的方向，并优化工艺与设备参数，稳定产品质量，保证生产顺行。通过研究，国丰钢铁公司生产的钢种中非金属夹杂物通过提出相应的改进措施非金属夹杂物Abstract Tangshan countries abundant steel Co., LTD. Was established in 1993, is a collection of oxygen generation, sintering, iron, steel, steel rolling as one of the major steel joint enterprise have annual iron, steel, the material the comprehensive production capacity of 8 million tons. In order to further improve the technical level, and increasing variety, improving the added value of the products, stable product quality, hebei union university and national abundant company agreed, widely for technical cooperation, give full play to the school and enterprise theory research, technology development and production management, and other aspects of the respective superiority, the kingdom of the typical steel smelting richly Q195 system research, production level and abundant clear countries advanced international and domestic steel mill in the relative position than describing the existing gap and further improve the direction, and optimization of process and equipment parameters, stable product quality, ensure the production line. During the experiment, the two countries abundant steel tudish optimized, and at the same time and tundish capacity expansion. Through the tundish slab before transformation, this paper analyzes countries abundant steel company in the production of steel non-metal inclusions, oxygen and nitrogen content in steel defects, through its transformation of production before and after the analysis of the data, and the corresponding improving measures and optimization scheme.
