7TH EUROPEAN COKE AND IRONMAKING CONGRESS - ECIC 2016

The effect of the mineral matter on the reactivity of a coke analogue was examined through the addition of binary and ternary combinations of magnetite (Fe3O4), troilite (FeS) and quartz (SiO2). The use of coke at a laboratory scale has issues arising from it heterogeneity and complex nature. The coke analogue was developed to help alleviate these issues, being a laboratory tool that has a...

In this study, a novel measurement method for coal thermoplasticity was developed, where permeation distance of thermally plastic coal into glass beads layer placed on the coal sample was measured. The permeation distance was roughly correlated with MF, however large deviation was observed especially for high fluidity coals. The deviation clearly showed the difference of coke pore structure...

Briquette blend coking process (BBCP) is one of the coal pre-treating technologies. In this process, a part of coal charge is briquetted, and the briquettes thus produced are charged into a coke oven chamber with the fine coal. The briquette blend leads to an increase in a coal bulk density in the coke oven chamber, which contributes to the improvement of coke strength. In contrast, there have...

The superior coke is one of essential condition for blast furnace stable and anterograde operation. Thus,the goal of the coking process is producing high-quality coke. Under the current situation of the increasingly shortage of coking coal, how to get rid of the dependence on high quality coking coal in the coke making production is a serious problem that iron and steel must be confronted...

The area of the surface of a coke that is accessible to gas is one important predictor of its reactivity. During burnout the surface area of the coke increases, and the rate of this increase differs between cokes. This increase has been attributed to the presence of fine closed pores in cokes that open up on burnout. Although it is certain that such closed pores exist, much is unknown...
