Abstract (en)
[origin: GB2477779A] A shielding device for a furnace charging system having a movable chute 104 within a housing aperture 110, the device comprising a plurality of blades 108 arranged so that at any point in the chute movement at least one blade spans a portion of the space between the chute and housing. The blades are mounted parallel as annular rings around a frustro-conical shield 106, and their outer edges trace a spheroid profile as the chute moves. The blades are less likely to distort compared to a spherical shield, but can flex if they contact housing 102. In other embodiments the blades can be angled, radial, mounted on the housing 102, or formed from corrugations of the shield 106. Space between blades may contain heat resistant packing, such as ceramic wool. A nitrogen cooling curtain may also purge dust. The furnace may be a blast furnace.
