Research and Application on Burden Movement Model for Bell-Less Top of BF

Abstract:

The mathematical model of burden movement for bell-less top of BF is described in detail, and the model of burden movement on rotating chute is improved combined with collision of burden to chute and effect of coriolis force. The influence degree of charging parameters on coke main striking position and stock flow width is investigated though establishing burden model. The research shows that: The changing of coke main striking point position is obvious under increasing decline angle of chute and length of chute, and for the stock flow width, the effects of decline angle of chute and depth of stock line are most important.
