A study on burden distribution of blast furnace with a bell‐less top

Abstract

The so‐called coke layer collapse phenomenon was observed on a blast furnace top model which was 1/4‐scale of No. 2 blast furnace of China Steel. A simulation program based on the Bishop simplified method of soil mechanics and the material balance was developed to identify the collapse occurrence and to predict the burden distribution after the collapse. A close agreement between the experimental results and the prediction of simulation program was found.

Key words:

• burden distribution
• coke layer collapse
• mixed layer
• blast furnace
• slope stability analysis
