    Rheology of coal is a key consideration in a coking operation. Coking coals swell, soften and then re-solidify to form coke when heated in the absence of air. The Gieseler Plastometer and Arnu Dilatometer are industry standard rheology tests used to evaluate the plasticity or rheological properties of coal.
