Abstract
A method for the controlled delivery of ore charges to a shaft furnace is disclosed. The method employs apparatus including a plurality of sensors on which an intermediate charge storage hopper is supported whereby continuous measurement of charge weight is permitted. The apparatus also includes means for establishing hermetic coupling of the storage hopper to the furnace whereby compensation for temperature and pressure induced positional displacements and biasing of the sensors is permitted.
