设 计 两 座 300t高 效 转 炉 炼 钢 车间摘 要本文主要介绍了 300 吨高效顶底复吹吹转炉及炼钢车间设计。炼钢过程就是铁水向钢水转变的过程,这对加入料及产物的成分、数量都有严格要求。本设计简要介绍了我国炼钢技术的进展历程。然后从物料平衡和热平衡方面进行计算,以 100千克单位铁水量为基础进行计算确定了合理的原料成分及原料加入量,以确保物质和能量的守恒;再依给定的 300 吨氧顶底复吹转炉设计出其炉型及相应的氧腔及水冷装置等。然后对连铸的生产能力进行计算,采纳三炉连浇、一机二流的三台连铸机进行同时生产,使连铸生产能力达到了估计的产量要求,确定炼钢厂的布置,最后简单设计烟气净化系统及精炼设备,最终完成设计。关键词:物料平衡和热平衡,氧气顶底复吹转炉,氧枪,炼钢车间,精炼设备AbstractThis paper introduces 300-tonefficient avoidances the combined-blowing converter and steel-making plant design .Steel-making process is the process of transformation of hot metal to the molten steel, which materials and products by adding ingredients, quantity, there are stringent requirements. The design briefly describes the history of steelmaking technology. And from the material balance and heat balance calculation to 100 kg units of iron water, calculated on the basis to determine a reasonable raw material components and raw materials by adding volume to ensure that materials and energy conservation; then follow the given 300 tons of BOF and the corresponding design of the furnace chamber and the water of oxygen devices. Then calculated the production capacity of continuous casting, continuous casting furnace with three, three second-rate one machine simultaneously casting machine production, the production capacity of continuous casting production reached the expected requirements, determine the layout of steel mills, and finally simple flue gas purification system design and refining equipment, complete the design requirements.Key...
