(57) Abstract :
The invention relates to the iron and steel industry, in particular to batch charging into shaft, mainly blast furnaces. The inventive
rotary batch distributor for shaft furnaces comprises an axle platform (1) and blades (2) which are equally spaced around the platform
and are fixed thereto by means of brackets (3). The surface of each blade is embodied in the form of an involute of a truncated cone
and consists of trapezoidal sections (4). The tilting angles of the trapezoidal sections with respect to the rotary batch distributor axis
and to a horizontal plane are defined by the involutes (5) of truncated cone which are focused at the same point of the rotary batch
distributor axis. The surface area of each blade is defined by the sector angle value ranging from 90 to 120° and by the radius of the
describe circle of the rotary batch distributor. The end part (6) of the blade whose surface area is equal to 0.05-0.10 of the blade
surface area is arranged at an angle of 125-140° with respect to the previous section. The tilting angle of a generator passing through
the base of the end part of the blade to the rotary batch distributor axis ranges from 88 to 90°. Said invention makes it possible to
provide any specified profile of the feedstock surface, starting from a cone-shaped whose tip is arranged on the blast furnace axis to a
peripheral, with a high circumferential uniformity.
