摘要

高炉炼铁是获得生铁的主要手段，高炉是炼铁的主要设备，高炉本体设计是炼铁厂设计的基础。本着优质、高产、低耗和对环境污染小的方针，长寿与高效是高炉设计与生产所追求的目标。本设计说明书进行的详细的设计及计算，同时结合国内外一些大型高炉的先进生产操作经验及相关的数据。力求设计的高炉做到高度机械化、自动化和大型化。以期达到最佳的生产效益。

本设计为1500m3高炉本体设计，所设计的炼铁高炉采用的高径比为2.78，高炉的有效利用系数为2.3t/(m3٠d)。车间采用岛式布置，出铁场采用圆形出铁场。其炉底和炉缸采用的先进的“陶瓷杯”技术来砌筑，从而达到了隔热保温、减少热损、保护炭砖的目的。炉腹部位用耐火度较高的铝碳转，炉腰和炉身下部用抗渣和防震较好的碳化硅砖，而炉身上部和炉喉用抗刷和抗侵蚀较好的高铝砖。高炉冷却方法采用了炉壳喷水冷却，和板壁结合的方式达到冷却效果，其中板壁结合中用到的冷却壁有光面冷却壁、第三代和第四代冷却壁。合适的钢结构和高炉基础设计保证了高炉的正常冶炼。

Abstract

Blast furnace iron making is the main means for pig iron, the main equipment of iron making is blast furnace, blast furnace design of ontology is the foundation of the iron mill design. In line with high quality, high yield, low consumption and pollution to the environment policy of small, long life and high efficiency is the goal of the design and production of the blast furnace. This design manual for detailed design and calculation, at the same time, combined with some large blast furnace at home and abroad advanced production operation experience and related data. Strive to design blast furnace of high mechanization, automation and large. In order to achieve the best production efficiency.

This design for 1500 m3 blast furnace body design, The design of the blast furnace high aspect ratio of 2.78,the effective utilization of blast furnace coefficient of 2.3t/(m3٠d).Workshop uses the island type layout cast house using circular cast house Blast furnace bottom and hearth uses advanced technology to building "ceramic cup", so as to achieve the heat insulation heat preservation, reduce heat loss and protect the carbon brick. Furnace belly with high refractoriness of aluminum carbon, bosh and furnace body with good slag resistance and shock-proof carborundum brick, The furnace body and brush with resistance and erosion resistance furnace throat good high alumina brick.Blast furnace cooling method USES a furnace shell water spray cooling, cooling effect and partition way, combined with the wooden partition used in cooling stave cooling wall has smooth surface, the third and fourth generation of cooling stave.Appropriate steel structure and foundation design guarantees the normal of the blast furnace smelting blast furnace.

Key word: blast furnace body;the lining;of blast furnace cooling system;steel structure
