The blastcups have local effects on the coke descent and have little effects on whether the cokes flow smoothly or not in case that cokebed has enough height.
Simulation research on the EAF dust online recycling and zinc oxide separation with cokebed filter was carried out by heating coke/dust samples in CO/CO2 gas mixture.
Different heat transfer coefficients have been obtained from a series of experiments aimed to simulate the heat transfer to molten iron droplets in the cokebed of a cupola.
