3200m3高炉本体及渣铁处理系统设计

中文摘要

目前我国钢铁企业蓬勃发展，许多钢铁厂都在新建或扩建高炉，高炉逐渐向大型化发展，因此在原有高炉的基础上引进新技术对高炉适当的改造设计是必要的。由于设计的需要，某些数据采自施工现场工长、炉长和工人的经验数据，许多参数的设计以理论数据为参照、以实际地区实际原料条件下的情况进行选定、以实际应用参数为基准。

本说明书采用包头地区原料条件下，对3200ｍ3高炉本体进行设计，其设计内容主要包括：高炉炉型设计计算、高炉炉衬选择计算、高炉冷却系统设计、高炉钢结构及基础设计、出铁场设计、炉前设备的选择确定、铁水处理系统设计、炉渣处理系统设计、绘制高炉本体立剖图和高炉出铁场平面布置图。高炉设计主要参数如下：利用系数－2.3；焦比－370㎏；煤比－170㎏；炉渣碱度－1.03；高炉高颈比－2.19；高炉有效高度－29.98m；日产铁－7360吨。

本高炉本体以五段炉型为标准，以适应原料条件为前提，冶炼过程能够顺行为保障，日产量最大，质量最优，能耗最低，寿命最长为目标进行设计。为达到以上目标，与传统高炉相比，本高炉炉型驱于矮胖型。为进一步提高高炉寿命，炉底炉缸采用全碳砖结构，这是因为包头矿含有高氟，对炉缸炉底的侵蚀严重。炉底采用了5段低络铸铁光面冷却壁，炉腹、炉腰及炉身下部采用铜冷却壁冷却，它的冷却强度大、对砖衬支撑作用强、损坏后可更换。高炉钢结构采用炉体框架式结构, 它的优点在于取消了炉缸支柱，风口平台宽敞，炉前操作方便。出铁场为环形出铁场，设置四个铁口连续出铁，它的优点在于布置紧凑,占地面积少,场地有效利用率高,自然通风条件好。渣的处理采用目前我国大高炉都使用的热法INBA渣处理系统，其工作效率高，对环境污染少。

Abstract

At present, China's iron and steel industry is flourish, and many iron and steel plant is building or expansion of blast furnace, blast furnace is gradualateing developed to large-scale, and therefore the basis of the original blast furnace to introduce new technology on the blast transformation and the appropriate design is necessary. As the design needs of some of the datas collected from the plant and the works , a long furnace empirical data, many of the design parameters to the theoretical data for the reference to the actual areas of raw materials under the conditions of the actual situation in selected parameters in the practical application of basement.

Baotou region of the specification of raw materials used under the conditions of the blast furnace of 3200m 3 to design, its design includes ： Design and calculation of blast furnace、 Calculation and option of blast furnace lining、 Design of blast furnace cooling system、 Blast furnace and basic steel structure design、 Design of cast house、Determine the choice of steel equipment、 Iron water treatment system design、 Slag handling system design、 Draw essence of blast furnace autopsy charts and blast furnace Layout field. The main blast furnace design parameters are as follows: use of coefficient of －2.3; coke ratio －370㎏; coal than －170㎏; slag basicity －1.03; blast high neck than －2.19; highly effective －29.98; Day total of iron production －7360t.

The blast furnace ia design as five as the standard to meet the prerequisite conditions for raw materials, smelting process to shun acts of protection, the largest output, the quality of the optimal energy

consumption and the lowest life expectancy of up to design goals. To achieve these objectives, as compared with the traditional blast furnace, the blast furnace to reduce the ratio of height to diameter, or blast furnace in the squat-type flooding. To further enhance the life of a

blast furnace, hearth to adopt advanced technology ceramic cup with hot bricks small carbon composite structure, which is refractory hearth with an important progress. Bottom using a 5-walled gray cast iron cooling smooth, belly stove, stove and furnace are lower lumbar copper cooling stave, and its cooling intensity, supporting the role of the brick lining, and damage can be replaced. Market for the iron ring of iron field, set up four consecutive iron taphole, it is the layout of the advantages of compact, small area, high space utilization, natural ventilation conditions. The use of slag handling large blast furnace in China are used Hing Hong - INBA slag thermal processing system, its high efficiency and less environmental pollution
