ことによって実現した。2. Description of the Related Art A typical prior art of a tap hole opening device is disclosed in Japanese Utility Model Publication No. 57-18420. According to the contents of this prior art, since the blast furnace tap hole opening device is configured to be able to be remotely operated, and set values are set for various operation amounts, it is possible to eliminate human differences due to operators. A device is made. That is, for remote operation, the main body of the perforator is moved back and forth, the metal rod for perforation is hit,

つながらなかった。Further, as a method for eliminating human error, a control valve is provided for each of the above-mentioned operations, and a comparison control section is provided for controlling the opening of the control valve so that the fluid pressure or flow rate matches the set value. Therefore, a constant striking force, rotating force, and feeding force are always obtained. However, in such means, since the striking force, the rotating force, and the feeding force are constant, when the mud material for hole closing is hardened by heat, the hole is not advanced and the set value is changed. Etc. extra operations are required. Another problem is that a detector for detecting the pressure or the flow rate is required for the pressure conduit corresponding to each operation, which increases the equipment cost. In order to realize further automation with such a device, a means for knowing the completion of opening is indispensable, but in this conventional means, the method of knowing the completion of opening is left to the judgment of the operator's eyes and ears. As a result, the problem of human error still remains, and automation does not lead to labor saving.

て自動運転の必要性が希求されていた。The tap hole of the blast furnace is closed by a mud material for closing the tap hole at the end of tapping. On the other hand, for the next tapping, there is a work to insert a holed gold rod into the tapped hole to open the tapped hole. At the time of inserting the gold rod, the holed gold rod is difficult to penetrate due to the heat curing of the mud material, and there is a problem that some drivers bend the gold rod. In addition, the judgment as to whether the holed gold rod has penetrated the tap hole is made by the human judgment involving the experience of the operator's eyes and ears. It was not possible to determine when to finish the proper opening work. In addition, since it is an operation near the taphole, which is dangerous, remote operation is desired from a safety point of view.
Moreover, the need for automatic operation has been sought after in order to save labor in front of the furnace due to the recent labor shortage.

An electromagnetic switching valve is provided so that each of the striking and rotating operations can be operated by an electric signal, enabling remote operation, so the driver does not have to go to the machine side for operation, and the environment is maintained in the cab. It became possible to operate in places such as. Further, although a series of operations can be automatically performed, as a problem at the time of opening, there are cases where it becomes difficult to proceed with the opening due to thermosetting of the mud in the taphole. At this time, for example, if the balance of the force of feeding, striking, and rotation is lost by an operation by a person, the holed gold rod will be bent. Further, in the conventional method, a pressure detector or a flow rate detector and a comparison adjusting unit are provided to adjust the opening degree of the power source supply control valve so that the pressure or the flow rate of the power source for feeding, striking and rotating becomes constant.

て済むようになる。Further, according to the present invention, as a method for determining the penetration of the metal rod for the opening, the depth of the opening changes each time depending on the length of the mud entering the furnace, but the method of stopping at the maximum settable depth of the opening is possible. And a method of stopping when the feed rate exceeds the set value even if it does not reach the maximum permissible set hole depth. Therefore, even if the operator does not judge the penetration state with his / her eyes and ears, the opening work can be automatically completed. That is, by making it possible to automatically operate the above-mentioned opening machine based on the set order, it is possible to further save the labor, and it is safe and the equipment cost is relatively low. .
