发明名称 Distribution chute control apparatus and method
摘要 Control over the direction and inclination of a charge distribution chute within a blast furnace is accomplished with a compact and reliable drive mechanism. The drive mechanism includes a rigid control rod for varying chute inclination angle and a gear drive which translates angular position commands in the form of rotation about a vertical axis to reciprocation of the control rod. The control rod and its gear drive rotate with the chute while simultaneously varying the inclination angle.
