説明

<p>This research aimed to investigate the production of ferro coke with high strength by cold pressing without adding binder, to meet the requirements of the metallurgical industry and avoid the environmental pollution problems caused by the hot pressing process. The effects of pressure and proportion of iron ore powder on the preparation of ferro coke from a weakly caking coal and a strongly caking coal were studied. The results show that when no binder is added, the ferro coke made from weakly caking coal has the highest compressive strength of 5.13 KN, while the ferro coke made from strongly caking coal has the highest compressive strength of 4.93 KN.</p><p>The relationship between the strength of ferro coke and the rate of dissolution loss was studied, and it was found that weakly caking coal produced under high forming pressure had good performance.</p>
