Abstract

To enhance the descent of droplets in the coke bed of a blast furnace, the sliding angle of the water droplet and the advancing and receding contact angles at the time of sliding were measured. Coke used as a reducing agent in a blast furnace was employed as a substrate. Because the shape of the coke surface varies with the gasification reaction with CO₂, the coke substrate was treated with heat (1 273 K) in a CO/CO₂ atmosphere. Irregularities of approximately several micrometers were formed on the coke surface by the gasification reaction, and the sliding angle of the droplet decreased.
