More specifically, the present invention relates to a slag removing method and a slag removing device that can be implemented as an alternative to the smashing work on the upper surface of molten steel, which has been performed at the time of measuring and sampling the temperature of molten steel in a ladle.

Description of the Related Art Slag and steel slag in iron making and refining, and slag such as entanglements in non-ferrous smelting solidify in a molten metal container or other auxiliary equipment, but these must be removed for work. In particular, when a slag having a composition of SiO 2 + CaO is once melted and then solidified, it becomes extremely hard. This is, for example, when the converter slag is mixed in the pan at the time of tapping,
It may also combine with subsequent added heat retention agents to form large lumps.

実に行う必要があった。FIG. 2 schematically shows, for example, a smashing operation that has been conventionally performed when sampling and temperature measurement from molten steel in a ladle. That is, in order to perform temperature measurement and sampling from the molten steel 6 in the ladle 7,
At least a part of the slag 5 which is solidified at the upper part of the molten steel 6,
For example, press the smashing machine head 8a of the smashing machine 8 to push the slag 5
By partially destroying the molten steel 7, the exposed portion of the molten steel 7 is formed, and by inserting the temperature measuring / sampling probe which is a part of the temperature measuring device 4 from the exposed portion, the temperature measurement / sampling of the molten steel 6 is performed. Was. In particular, the temperature measurement performed before the RH degassing process is extremely important for determining the subsequent processing conditions, and this temperature measurement needs to be performed particularly quickly and surely.

測温を行うことは容易ではなかった。However, in this technique, the smashing machine is mechanically operated, and therefore, for example, as shown in FIG.
The slagging machine head is caused by immersing the slag in the molten steel 6.
The metal 9 adheres to the tip of 8a. Therefore, in order to continuously use this device, the grinder machine head should be used regularly.
Since it was necessary to replace 8a, it was not easy to measure temperature continuously and quickly.

滓割り装置が大型化してしまうという問題があった。Further, in this device, a thrust of about 2 to 5 tons is usually required as a pressing force at the time of smashing, but since the smashing position and the temperature measuring / sampling position are at the same place, the devices are separated from each other. There is a problem that it is necessary to avoid interference and the size of the smashing device becomes large.

In Japanese Patent No. 53, a slag portion is provided in front of the temperature measuring / sampling probe, and the slag portion on the molten metal is divided by the slag portion,
A technique has been proposed in which the temperature measurement / sampling probe is inserted to allow the tip to reach the inside of the molten metal, and then the temperature measurement or sampling is performed. Conventionally, such a technique has been frequently used.

In the technology proposed by Japanese Patent No. 5153, since slag or molten metal adheres to the slag part, it is necessary to carry out repair work such as removal of slag and maintenance (especially clogging of internal holes) every time measurement is performed. is there. Since the repair work is difficult to automate, extra man-hours are required, and the labor-saving effect is lost.

の欠点があった。As described above, in the conventional slag removing method and slag removing apparatus, the scale of the slag removing apparatus is large because the slag removing device is mechanically removed, and the slag removing machine head is a consumable item. In addition, there are drawbacks such as the replacement frequency, the replacement work time, and the number of replacement steps.
