7TH EUROPEAN COKE AND IRONMAKING CONGRESS - ECIC 2016

Blast furnaces do not operate properly with fine-grained iron ore. To make use of such ores, they must be processed efficiently into pellets in high scale traveling grate pelletizing plants. Pellets are small balls of iron ore. Such furnaces are lined with thousands of tons of refractories that play an important role in operation stability and energy efficiency. Partition walls are a critical part of the design by dividing the process area above the grate into different temperature zones. These partition walls situated above the traveling grate and span across the width of the furnace walls. This paper describes the development of a new type of partition walls supported by finite element analysis of the thermo mechanical behaviour of those walls.
