摘 要

本说明书在实习和参考文献的基础上，对所学知识进行综合利用。讲述了华南地区设计一座年产780万吨钢全连铸转炉炼钢车间的方法和步骤，说明书中对车间主要系统例如铁水供应系统，废钢供应系统，散装料供应系统，铁合金供应系统，除尘系统等进行了充分论证和比较确定出一套最佳设计方案。并确定了车间的工艺布置，对跨数及相对位置进行设计，简述了其工艺流程，并在此基础上进行设备计算，包括转炉炉型计算，转炉炉衬计算及金属构件计算，氧枪设计，净化系统设备计算，然后进行车间计算和所用设备的规格和数量的设计，在此基础上进行车间尺寸计算，确定各层平台标高。最后对转炉车间设计的环境和安全要求进行说明。

为了更加详细说明转炉车间设计中的一些工艺及设备结构，本设计穿插了图形，为能够明确、直观的介绍了转炉炼钢车间的工艺布置。

关键词: 转炉 车间设计

Design an annual production capacity of 7.8 million tons full casting steelmaking plant in southern China

Abstract

This instruction manual is based on the practice and references, and comprehensive utilization of the learned knowledge. Design a converter workshop about the methods and procedures of the workshop manual major systems such as molten iron supply systems, scrap supply system, bulk material supply system, ferroalloy supply system, dedusting systems were fully demonstrated and compared to determine a set of best design solutions. And to determine the process layout of the workshop on the number and relative position of the cross design, outlining its process, and on this basis calculated on the device, including the calculation of the converter furnace, converter lining calculation and metal components calculated lance design purification system equipment calculations, then plant and equipment used in calculating the size and number of the design, conduct workshops on the basis of size calculations to determine the elevation of each layer platform. Finally converter workshop designed for environmental and safety requirements will be explained.

For a more detailed explanation of some of the converter plant design process and equipment structure, the design interspersed with graphics, to be able to clear, intuitive introduction to the steelmaking plant process layout.

Keywords: Converter; Workshop Design
