When the piston rod 54 is pushed out toward the furnace by driving, the wheels 43 attached to the truck 40
, 43 , . 31 and bushing rod 32 move the raw material distribution plate 30 toward the furnace core through the gas seal devices 15, 15, 15 of the lid 14 attached to the opening 12 of the furnace wall 11, and this movement causes the raw material to be distributed. The plate 30 gradually contacts the side surface of the furnace core from the lower part to the upper part, and as the contact position changes, the falling direction of the raw material changes from the inside of the furnace wall 11 to the furnace core side, and the raw material is deposited in the furnace. It is deposited in an arbitrary mountain shape.
