2座80吨、年产良坯量为174万吨的氧气转炉炼钢车间设计 ? Abstract The design for the 2×80 tons, the annual output of 1.7 million tons of oxygen converter steelmaking workshop. The workshop of main systems for: the molten iron supply system, disperses the shape material supply system, scrap steel supply system, the ferroalloy supply system, flue gas purification system, pouring system, refining outside the furnace system, etc. These solutions are determined by comparing and the more reasonable for the design scheme, and adopted the advanced technology. This design includes bof model calculation, oxygen lance calculation, flue gas purification system calculation, the calculation of the workshop equipment and across the arrangement between. In addition, our design has also used the many new technologies such as: by slag splashing furnace technology, the molten iron the desulfurization, slab continuous casting and rolling technology, these technologies have reached the international advanced level. This design has two of the converter, the size of converter are for 80 t, average oxygen blowing time for 38 min, pure oxygen blowing for 15 min, machineries for 79.5% of converter, the main raw material of converter is metal, and scrap steel and other auxiliary materials. Good billet the yield of 99%. In addition, this workshop and refining outside the main thread feeding and vacuum deairing with the means. This workshop for continuous casting of casting way, workshop of the final product for billet. Through the design, whole master steelmaking process flow and workshop process arrangement, the further understanding of the world steel dynamics.
