Abstract:
1. A distribution chute for a charging device that is configured for rotating said chute about a rotational axis and pivoting said chute about a pivoting axis, in particular for a charging device of a shaft furnace, said chute comprising: an upstream mounting head and a chute body having an elongated downstream chute portion with a longitudinal axis, said downstream chute portion defining a sliding surface, on which charge material can slide, and an outlet, through which charge material can leave said chute body during operation; at least two lateral suspensions on said mounting head for mounting said chute to at least two corresponding support flanges of the charging device, said support flanges being pivotable about said pivoting axis in a raising sense for raising said outlet to a radially outermost charging position and in an opposite lowering sense for lowering said outlet to a radially innermost charging position with respect to the rotational axis; wherein said chute has a center of gravity and said suspensions define a first and a second tilt point, respectively, about which the weight of said chute exerts jamming torque onto the support flanges of the charging device when said chute is mounted to the charging device; wherein the ratio of the distance between each one of said tilt points and said pivoting axis to the distance between the first and second tilt points amounts to 0.25 at most; and wherein said suspensions are arranged so that an oriented acute angle from said longitudinal axis to a plane through said tilt points and said center of gravity has an angular measure in the raising sense comprised in the range from −5° to 15°.
