7TH EUROPEAN COKE AND IRONMAKING CONGRESS - ECIC 2016

Inverse geometry heat transfer analysis using thermocouple data is often used to estimate the remaining refractory thickness in a blast furnace hearth. However, multiple combinations of refractory / skull thickness solutions exist for a single set of thermocouple data. The results of this method are also sensitive to the quality of thermocouple data. An alternative approach uses...

The objective of this paper is to develop the particle flow simulation in a charging process of a bell-less type blast furnace by using Discrete Element Method (DEM). The particles behaviour in a rotating chute was modelled, and the burden distribution was analysed. The measurement of the particle behaviour in a scaled-down experimental blast furnace was also carried out to validate the...

The future of the low emission blast furnace (BF) ironmaking might result in significant changes in the applied reductants. Today, majority of the Western Europe blast furnaces are operated with pulverized coal injection, but alternative renewable reductants such as torrefied biomass or charcoal could also be applied in BF injection. In addition, top gas recycling blast furnace (TGR-BF)...

Ironmaking blast furnace (BF) operation and control is quite a challenging task due to the “black box” nature of the process. The difficulty is further aggravated by the fact that the overall performance of the furnace is simultaneously influenced by both in-furnace and out-of-furnace processes. However, the difficulty can be somewhat mitigated through application of empirical knowledge,...
