Abstract
In the sintering shop at OAO Ural’skaya Stal’, industrial trials are conducted with a view to improving the pelletization by wetting the sintering batch with water-soluble organic surfactants. The use of surfactants improves the granulometric composition of the batch, its gas permeability, and hence the sintering efficiency. The use of surfactant is most effective with optimal wetting of the batch (7–8%), with consumption of the experimental binder at a rate of 1.2–1.6 L/h. (The surfactant concentration in aqueous solution is 0.3⎯0.4 mL/L.)
