300平米烧结机烧结厂设计

摘要

烧结矿在高炉炼铁生产中是很重要的一种含铁原料，它的质量好坏和产量的高低直接影响高炉的冶炼效果。因此，设计一个合理的烧结工艺流程是非常重要的。

在整个设计过程中吸收了很多国内外先进厂家的经验和技术，根据所学的专业知识，设计一台300 m2的烧结机。其技术指标为年产烧结矿307.48万吨，R=1.8，T Fe≥57%，成品矿粒度50-5 mm，转鼓指数≥70%。

本设计说明书中对所设计的烧结厂工艺进行了简要的介绍，并进行了物料平衡及工艺流程的计算，设备选择计算，确定了含铁原料、熔剂、燃料等需要量，并选择了与之相应的设备配置。全文分为：绪论；原料、熔剂和燃料；生产规模，工作制度及产品方案；烧结工艺流程及物料平衡；烧结物料平衡与热平衡计算；环境保护与综合利用六个部分。

本设计中，充分考虑了设备自动化控制及环境保护等方案的需要，选择了当前先进的工业设备。在计算基础上又绘制了图纸说明并编写了设计说明书。

Abstract

In blast furnace ironmaking, the sinter is an important iron material. The productivity and quality of the sinter have directly effect on blast furnace ironmaking. So it is very important to design a sensible singtering craft.

In the design prossess, Some advanced experience and technology of domestic and foreign manufactures has adopted. According to the study of expertise, the requirement is to design a 300 m2of sintering craft. The technical indicators is following: the year quantity of sinter is 307.48 ten thousand ton, R=1.8, TFe≥57%, drum index is no less than 70%, finished mine size is from 50 mm to 5 mm.

It is introduced the process of the sintering plant in the design specification. And calculation in material balance, process and equipment selection, determine the ferrous materials, flux, fuel and other requirements, and selection of the corresponding fitness equipment configuration are displayed. The thesis is composed of six sections: introduction; material of iron ores, fluxes, flues; capacity, working rules and production program of the sinter plant; process and material balance calculation; sintering material balance and thermal equilibrium calculation; environment protection and comprehensive utilization.

The equipment autocontrol and environmental protection are fully considered in the design. The current advanced craft equipment was used. On the base of calculation,the drawings were drawn and the design specification was complied.
