Abstract
PURPOSE: To improve accuracy of control of raw material feed to a hopper and discharge from the hopper, by making the raw material hopper open to atmospheric press. side while raw material being fed to the hopper, and open to furnace-top-gas side while the raw material being charged from the hopper to the furnace so as to make the hopper press. uniform.
CONSTITUTION: While raw material being fed to a raw material hopper I, the hopper I is opened to the atmosphere, and the gas contained in the hopper I is released in order to make the raw material feed smooth. Then furnace top gas is introduced into a raw material hopper II with a uniform press. valve 13b opened so as to make the press. of the hopper II equal to that of the furnace top 1. While raw material being charged to the furnace, furnace top gas in a volume equal to that of raw material is simultaneouly introduced through a rising pipe 12, press.- uniformizing pipe 14b and mutual gas pipe 2b to the hopper II to help the raw material flow down. When the hopper II is emptied, it is prepared for raw material feed with seal valve 16b and the press.-uniformizing valve 13b closed. Then the press. of the hopper I is made equal to that of the furnace top 1, and raw material charge to the furnace top 1 is started.
