PROBLEM TO BE SOLVED: To provide a furnace top charging apparatus in a bell-less blast furnace with which when charging a raw material into the blast furnace by using the furnace top charging apparatus having a swing chute, the dropping positional precision of the charged material can be improved and thus, coke can be charged into the center part of the blast furnace at good precision.;SOLUTION: The furnace top charging apparatus having the swing chute in the bell-less type furnace, in which the swing chute is a trough-shape and has a structure partially closed with a contracting flow plate in the trough-shaped opening part at the lower part and the contracting flow plate is arc-state in the cross-sectional shape and is inclinedly set so that the distance to the bottom surface of the swing chute shortens as the lower part of the bottom surface thereof, is used. It is desirable that the end part of the contracting flow plate protrudes from the lower end part of the swing chute.;COPYRIGHT: (C)2007,JPO&INPIT
