Abstract
A charge metering system for a shaft furnace is disclosed. The furnace charging apparatus includes means for continuously measuring the charge material in a supply hopper and a metering valve for controlling the material flow rate from the supply hopper. In order to permit accurate charge weight measurement the supply hopper is isolated from dimensional displacements which may be induced in the furnace and associated equipment during operation by means of an articulated suspension system comprising a three hinged arch construction.
