摘要： PURPOSE: To permit taking-out of an intermediate product in a blast furnace in an airtight state by connecting seal chambers having respectively feeding-out valves and seal valves at the top and bottom to the bottom of the blast furnace and providing moving chambers via press contact device on the lower side of the lower seal valves.
CONSTITUTION: An upper seal valve 5a is opened and after an upper feeding-out valve 4a is opened to feed out an intermediate product of a high temp. at a specified rate from the discharging hole 3 in a furnace bottom 2 to the inside of a seal chamber 8a, the valve 4a then the valve 5a are closed. A control valve 9a in a hermetic piping 19a is opened to release the pressure in the chamber 8a in succession to the above-mentioned operation. The valve 9a is then closed and a lower seal valve 12a and a lower feeding-out valve 11a are successively opened to feed out the intermediate product into a moving chamber 16a. The valves 11a, 12a are successively closed finally and after the connection by a press contact device 19a is released, the chamber 16a is moved to the succeeding stage. The taking-out by the other system is performed simultaneously or with a time lag.

摘要： PURPOSE: To center the flow of high temp. gas and to apply effectively heat to the briquettes in a pipe by feeding the coke-contg. bauxite briquettes through a center feed pipe to the high temp. region at the top end of a raceway and charging coke on the circumferential wall side.
CONSTITUTION: The coke in a coke bunker 16 is supplied successively through a coke feed port 15 into the position in proximity to the furnace wall in a furnace mouth part 14 and forms a conical pile, from which the coke flows into the upper part of a raceway 3 and reacts with the O
2 from a tuyere 2, thus forming high temp. gas. Since the high temp. gas has the smaller pressure drop in the central part of the furnace than in the wall part thereof, the gas is easier to rise along a center feed pipe 4 at the center. On the other hand, the coke-contg. bauxite briquettes or aluminum ores in a briquette bunker 5 are preheated by the high temp. gas ascending through many small holes of the pipe 4 during falling in the pipe 4 and are reduced in the bottom end part of the pipe 4, by which the ores are made into a crude Al alloy. Said alloy drops onto a furnace bottom 24 without passing through the inside of the raceway 3.

摘要翻译：目的：使高温流动居中。气体，并通过喂食焦炭来有效地将热量施加到管道中的团块。铝土矿块通过中心进料管高温。在轨道顶端的区域和周壁上的充电焦炭。构成：将焦炭仓16中的焦炭依次通过焦炭进料口15供入到炉口部分14中的靠近炉壁的位置，并形成锥形桩，焦炭从该塔顶流入上部跑道3，并与风口2的O2反应，形成高温。加油站。由于高温气体的中心部分的压降比壁部的压降小，气体容易沿着中心的中心进料管4上升。另一方面，焦炭砖砌块5中的铝土矿块或铝矿石由高温预热。气体在管道4落下时通过管道4的许多小孔而上升，并且在管道4的底端部分被还原，由此将矿石制成粗Al合金。所述合金在不通过滚道3的内部的情况下滴落到炉底24上。
