、緊急処置時に問題があり、完全なる装置とは云えず、
実用化は困難であった。Conventionally, there are several types and mounting methods of antioxidants, such as a bolt mounting method in which the joint part of the antioxidant is bolted, and a notch and an engaging convex part that can be fitted into each other on the circumference of the joint part. This has been done using the so-called bayonet method, in which the device is installed and fitted and then rotated to engage, or the screw-in method, in which it is directly screwed together, but both methods require time and effort to attach and detach, and emergency measures are required for handling. There are occasional problems and it is not a perfect device.
Practical implementation was difficult.

続してなる酸化防止器取付装置の構造である。A flange 4 is provided at the lower end around the spout on the bottom surface of the ladle that accommodates molten steel or the open nozzle 3 on the bottom surface 2 of the tundish 1.
A cylindrical fixing frame 5 is fixedly installed, and a flange 7 facing the flange 4 is provided at the upper end of a flexible cylindrical diaphragm 6 made of a heat-resistant mineral material that does not easily pass molten steel. An antioxidant 9 with an upper frame 8 attached thereto is provided, and an inert gas blowing port 10 is formed on the side of the upper frame 8 of the antioxidant 9 to which an inert gas blowing hose 11 is connected inside the cylindrical diaphragm 6. death,
Further, the opposing surfaces of the flange 7 of the oxidation preventer 9 and the flange 4 of the fixed frame 5 are finished flat so that there are no significant irregularities, and one of the opposing surfaces of the flanges 4 and 7 is coated with a magnetic material 1.
2, a magnet 13 is attached to the other side, a heat-resistant backing 14 is embedded in the upper frame flange part 1 to ensure sealing, and both flanges 4 and 1 are removably connected by the magnet 13. This is the structure of the preventer mounting device.

When the upper frame flange 7 is aligned with the flange 4 of the fixed frame 5 provided on the bottom surface 2 of the tundish 1, the mutual flanges 4
, 7 by the magnetic body 12 and magnet 13 of both flanges 4, 7.
are suction-adhered, and the backing 14 maintains the airtightness of the connecting flange 4.7, and the lower end of the flexible cylindrical diaphragm 6 is attached to the upper surface of the mold 15, which moves up and down in the continuous casting machine. The injected molten steel 16 from the nozzle 3 of the tundish 1 to the mold 15 is surrounded and sealed by the cylindrical diaphragm 6 and is passed from the inert gas injection hose 11 to the inert gas injection port 10. By continuously feeding the inert gas 17 into the cylindrical diaphragm 6, the inside is filled with the inert gas and a positive pressure is maintained, so the injected molten steel 16 is completely isolated from the atmosphere and its oxidation is prevented. It can be prevented.

である。In addition, in the continuous casting apparatus, a receiving trough (lounter) 18 is installed between the tundish 1 and the mold 15 so as to be able to pivot freely around a pivot point so that the pouring of molten steel can be stopped and poured outside in case of an emergency. However, mold 15
In the event of an emergency such as a breakout or overflow, when the receiving gutter 18 is moved to the downstream position of the injected molten steel 16, the antioxidant 9 is pushed by the receiving gutter, overcomes the magnetic force, and is removed from the fixed frame 5. The injected molten steel 16 is blown away and falls into the receiving trough 1.
