SHAFT FURNACE CHARGING APPARATUS |
摘要 |
The delivery of charge material to the hearth of a pressurized blast furnace under the influence of gravity is accomplished without the necessity of changing the direction of material flow at a point exterior of the furnace. The rate of flow of the charge material, which moves in a vertical stream, is controlled by a metering device including a pair of overlapping register elements which define a variable size aperture which remains generally symmetrical with respect to the stream axis. |
