This is the result of the reaction progress in step 1 up to that point, that is, the change over time of the gas composition, temperature, etc. due to the surrounding air. However, with the method of inserting the charge into the furnace through the furnace wall and collecting the charges and gas, it was difficult to simply measure or sample 70 sweetfish, and it was difficult to fully grasp the actual state of the reaction inside the furnace. I had a problem.

An observation window J6 is installed, and the fiberscope 12 is inserted into the fiberscope 12. The observation window 16 is valved so that the charge to be collected inside the furnace, that is, into the charge collection container 20, is observed and collected. In the figure, 5 is an N2 supply hole for purging.

捷わりを上昇し、ガス吸引孔」８に達することはない。The observation window 16 according to the invention is a glass plate, and a gap is provided around the glass plate so that the debris can pass through. Therefore, by sending nitrogen gas through the N2 supply hole 5 in a part of the main body, the dust near the glass plate is removed, but the nitrogen gas flows out from the observation window 16 into the furnace. On the other hand, the gas in the furnace is taken in from the waste suction hole 18, and the gas sampling pipe]
5, the gas is sampled from the gas sampling hole 6 and guided to a gas analyzer. This gas sampling hole (8) is made to protrude sufficiently outward from the observation window (6), so that the nitrogen gas flowing out from the observation window rises along the bends of the main body along with the gas inside the blast furnace. , the gas suction hole 8 is never reached.

炉内の正しいガス採取と正確な炉内測温が可能である。The thermometer]-9 passes through the gas sampling tube 15 and reaches the gas suction hole 18-4, so it is not directly affected by the water that cools the main body. Because of this configuration, it is possible to collect the correct gas inside the furnace and accurately measure the temperature inside the furnace.

ると、ワイヤーロープを緩め本体を自重で降下させる。Measurements and sample collection inside the furnace using the device of the present invention are carried out as follows. The main body of the sonde 1 shown in Figures 1, 2, and 3 is hung semi-vertically with a wire rope, and its lower end is suspended vertically.
After being inserted into the sealing device 3 shown in the figure, the valve 4 is opened to lower it into the furnace. When the tip of the main body reaches the surface of the charge inside the furnace, the wire rope is loosened and the main body is lowered by its own weight.

２１により停止する。At this time, the charge collection container 20 is pressed against the bottom of one body, so that no charge can enter therein. In this state, the main body slowly descends together with the contents in the furnace. In the process, by measuring the temperature inside the furnace and sampling the gas inside the furnace, changes in the anti-core atmosphere that the charge near the tip of the main body comes into contact with as it descends can be detected. reaction time is 6t
! I decide. After the tip of the main body reaches the level of 91, the wire rope is tightened to stop the main body from descending. Then, only the charge collection container 20 is lowered to a predetermined depth together with the contents in the furnace, and is stopped by the stopper 21.

ことも可能である。The charge collection container 20 is now open and the charge in the furnace flows into it. , and then pull up the main body 7- with a wire rope to a position where the valve 4 can be closed, and after cooling the charge sufficiently here, the valve 4 is closed.
It is possible to completely pull out the main body from the seal part 3 by closing it and test it completely. At this point, it is effective to flow nitrogen gas through the fiber tube 11 for sample disposal.
If a fiber tube and fiberscope are not installed, it is also possible to use the drive shaft tube 13 to flow cooling nitrogen.

In addition, a method of burying it in the furnace charge by reheating is adopted, and furthermore, in the process of descending into the furnace, changes in the reaction mass in contact with the charge near the tip of the device are measured, The charge can then be harvested.

体の損傷が少ない点も有利である。In an operating blast furnace, the charge is charged into the furnace from the top of the furnace, and at the same time drying and preheating begins, and the reaction in the furnace begins soon. The condition of the furnace atmosphere that causes such a change in the material can be understood as the entire process from the time the charge first enters the furnace to the time point 1 when it is sampled. It is possible to interrupt the measurement at various stages of the reaction process or temperature raising process, sample the 11 self-luminous charges, and examine their properties. This series of information has not been previously available and will greatly contribute to the elucidation of the reactions inside a live h-reactor. 1. If you manage the operation by looking at the daily conditions inside the furnace, it will be possible to take appropriate operational actions, which will stabilize the operation of the cylinder furnace.
A significant effect can also be expected in terms of lowering the fuel ratio. Also,
The device is easy to operate, and since it is naturally buried vertically in the furnace, it does not require great structural strength and is advantageous in that the main body is less likely to be damaged.
