一、前言高炉设计的最大问题是如何保持炉况稳定和怎样延长高炉寿命。对高炉寿命影响很大的炉身下部和炉缸的耐火砖衬及冷却系统,已经逐年得到改进。本文介绍了冷却壁和内衬改进研究的概况,并根据冷却壁高炉的生产数据,对应用到高热负荷的炉身下部的新型冷却壁和耐火材料的效果做了评价。首先介绍开发第三代冷却壁时有关热负荷试验的主要技术研究成果。然后介绍安装第三代冷却壁的高炉的热负荷分布和将这些结果反馈应用到冷却壁设
First, the foreword The biggest problem of blast furnace design is how to maintain a stable furnace condition and how to extend the life of the blast furnace. Refractory brick linings and cooling systems, which have a great influence on the life of the blast furnace, have been improved year by year. This paper presents an overview of improved research on cooling walls and linings and evaluates the effectiveness of the new cooling walls and refractory materials applied to the lower part of the shaft with high heat load based on the production data of the cooling wall blast furnace. First of all, introduce the main technical research results about the thermal load test when developing the third generation cooling stave. Then introduce the heat load distribution of blast furnace installed the third generation of stave and apply these results to the stave
