SUMMARY:Gasification and mechanical strength of metallurgical coke
DESCRIPTION:A blast furnace (BF) is the dominant process for making iron in the world. The blast furnace is charged with coke and iron burden materials including iron ore pellets, sinter and/or lump ore. Coke has several functions in blast furnace process. Coke acts as a fuel in the blast furnace, it acts as a reducing agent for iron bearing materials and it provides support for the charge material inside the blast furnace providing permeability structure that enables gases to flow upwards. Compression strength of coke is one way to describe coke’s ability to act as a skeleton of the blast furnace charge. This work focuses on the compression strength of two different coke types after gasification.

The gasification experiments were conducted in two different dynamic atmospheres acquired from an actual industrial blast furnace (CO-CO2-N2 and H2-H2O-CO-CO2-N2). Compression strength after reaction was studied with Gleeble 3800 thermochemical simulator. Light optical microscopy was used together with image analysis to gather information about pore area. Differences were found in pore areas as well as in compression strengths between the coke types as expected. Furthermore, the differences in atmospheres (with/without H2 and H2O) also yielded different results making strain at breaking point happen to a narrower scale when hydrogen and water vapor were presence at the atmosphere.
