Abstract：In order to reduce production cost, Jinan Steel transformed three 4.3 m top charging coke ovens for stamping coke production. Because of relatively small shrinkage of the coal in coking process, imperfect transformation facilities, unreasonable operation and other reasons, some problems appeared in the production, for example, large coke pushing current, serious leaking of oven body and poor dedusting effect. By controlling the G value of mixed coal below 72, reducing the density of briquette heap, narrowing the width of briquettes and other measures, the existent problems were avoided or relieved. In view of different structure and production characteristics between top charging coke oven and tamping coke oven, caution should be taken in the top charging coke oven transformed to tamping coke production.
