PROCESS FOR ACTUATING AN OSCILLATING SPOUT IN AN ENCLOSURE UNDER PRESSURE, APPARATUS FOR THE PERFORMANCE OF THIS PROCESS AND CHARGING INSTALLATION FOR A SHAFT FURNACE EQUIPPED WITH SUCH AN APPARATUS

摘要

METHOD AND APPARATUS FOR CONTROLLABLY CHARGING A FURNACE The position of the discharge end of a tubular member, supported from its first end so as to be rotatable about a first axis and pivotal about a second axis which intersects and is transverse to the first axis, is controlled from a remote location. The controllable tubular member may be the distribution spout of a shaft furnace charging installation which is mounted between the branches of a suspension fork which is rotatable about its own longitudinal axis. A motion transmission mechanism extends through the suspension fork and, in cooperation with the movements of the fork itself, transmits the movements imparted to a control device, which is caused to undergo precisely the same movements as it is desired to have the spout perform, to the spout.
