II年产 100 万吨电炉炼钢车间设计摘 要当前电弧炉正朝着大型电弧炉、超高功率供电技术、采用各种炉外精炼、发展直接还原法炼钢、逐步扩大机械化自动化及用电子计算机进行过程控制等的发展，所以我们进行了电炉炼钢的设计，以适应潮流的发展。电炉的主要产品是钢材，而钢的质量取决于电炉冶炼技术和工艺，目前我国钢铁产业大量整合趋向于集中，整合资源优化升级。本设计根据指导老师的课题范围，查阅相关资料，结合重庆地区实际条件，优化设计年产为 100 万吨的电炉间。本次设计查阅国内大型电炉车间设计的相关内容和文献资料，明确本次设计的目的、方法，并向老师请教可行性方案。结合炼钢设备及车间设计. 、 炼钢厂设计原理 、 炉外处理等资料进行设计提纲的书写。对电炉进行配料计算，计算出电炉炼钢的原料配比。对电炉电气设备、炉外精炼、连铸系统、车间烟气净化系统、炼钢车间布局，结合国内大型电炉进行设定并向田老师探讨可行的方法和数据。绘制电弧炉平面图和电炉炼钢车间平面布置图。关键字关键字：电弧炉 车间设计 连铸 炉外精炼ABSTRACTIIIABSTRACTThe current is moving large electric arc furnace electric arc furnace, high-power power supply technology, using a variety of refining, the development of direct reduction steel making, and gradually expand the use of mechanization and automation and process control computer for the development, so we were EAF designed to fit the trend of development. The main products are steel furnace, and the quality of steel depends on the electric furnace smelting technology and techniques, present a large number of integrated steel industry in China tend to focus on integrating resources for optimization and upgrading. The design of the subject areas under the guidance of teachers, access to relevant information, combined with the actual conditions in Chongqing, optimal design capacity of 100 tons of furnace plant.The design of access to large domestic electric furnace workshop content and related design documents, specifically designed for this purpose, methods, feasibility of the program to the teacher for help. With “steel-making equipment and plant design.“, “Steel design principles“, “ outside the furnace processing “, etc. to design the outline of the writing. Calculated on the EAF ingredients to calculate the ratio of electric steelmaking raw materials. Electrical equipment on the furnace, secondary refining, continuous casting system, the plant flue gas purification systems, steel plant layout, IVcombined with the large EAF set to Tian to explore feasible approaches and data.
