- Kinetic modelling of coking coal fluidity development
The coal sample can melt steadily with the temperature increase, achieving the maximum fluidity (Fmax) when the total amount of metaplast available turns into the plastic state Coal behaviour while it is being heated can be described by two mechanisms
- Ironmaking Steelmaking fluence of coal particle composition © The . . .
Fluidity development in coal particles depends on particle size and the extent of association between constituent maceral grains As such, determining the com- position of coal particles is crucial to understanding the drivers of thermoplastic fluidity
- New Evaluation and Blending Technique of Coking Coal Based on Surface . . .
Gieseler maximum fluidity (MF, JIS M 8801) is used as an index of the caking property The optimum range of MF is 200 to 1 000 ddpm Since coke strength tends to decrease when MF is outside this range, the development of techniques which make it possible
- Exploring the Coking Process: Insights into the Structural . . . - SSRN
These parameters are closely related to the degree of coal metamorphism, reflecting the cohesiveness, fluidity, and plasticity of the plastic layers The properties of the plastic layer in coking process are fully characterized and quantified by the results obtained
- THE INFLUENCE OF PLASTIC PROPERTIES OF COAL BLENDS ON EVOLUTION OF . . .
Correlation between cokes anisotropy and fluidity of initial blends was detected Keywords: coal blends, coke, optical texture, plasticity Introduction Cokes manufactured at high temperatures (HTs) are used in the steel industry for the reduction of iron ore to pig iron in blast furnaces
- Plastic Properties
Several authors have published methods to predict coke strength using the plastic temperature range and or maximum fluidity as determined by the Gieseler test The maximum fluidity determined by the Gieseler is very sensitive to weathering (oxidation) of the coal
- Fluidity development of coking coal - Nottingham ePrints
Limited correlations were found for single coals between rheometry and 1H NMR, where G” and η* exhibited R2 values of between 0 8 – 0 9 with the %fluid H However, good correlations were found between G” (0 90 – 0 99) and η* (0 89 – 0 98) with %fluid H for medium fluidity coal blends
- Influence of Geology on CSR (Coke Strength After Reaction With C02)
CSR, or coke strength after reaction with C02, has become the more important means of evaluating the quality of coking coal and of controlling blast furnace performance within Pacific rim steel-producing countries, and is now a principal criterion by which coals are selected to make blast furnace coke
- Kinetic modelling of coking coal fluidity development - Springer
The coal sample can melt steadily with the temperature increase, achieving the maximum fluidity (Fmax) when the total amount of metaplast available turns into the plastic state Coal behaviour while it is being heated can be described by two mechanisms
- Metallurgical Coal – IspatGuru
The Gieseler plastometer test measures the fluidity or plasticity of coking coal in a cylinder with a stirrer inserted inside The cylinder of coal is heated at a constant rate as steady torque is applied to the stirrer
