- a well-known slide valve device (hereinafter referred to as an SV device) includes a plurality of plate bricks and a housing mounted on the bottom of a molten metal container for storing the plate bricks. And a sliding plate drive mechanism and a sliding plate drive mechanism that support an appropriate surface pressure between the contact surfaces of the plate bricks.
- the plate bricks are replaced with new ones when they reach the end of their service life.
- the replacement work is done after opening the SV unit online and removing each plate JL one by one.
- One new plate brick is set, the surface pressure is applied by the surface pressure, and the replacement is completed.

- the molten steel leak and the external air entrained in the molten steel It is currently considered as a large plate brick because it is necessary to prevent it from becoming large.
- the plate brick replacement work which is performed online after the installation is completed, is performed 20 to 30 minutes after the installation is completed. This work takes about 15 minutes, so it is a very hot heavy reinforcing work, and because it is a very hot heavy reinforcing work, the work itself is easy to get rid of. It causes troubles such as steel leakage accidents due to tomis, etc. Also, it is difficult to mechanize because refractories are set one by one.
- the working atmosphere is poor because dust is removed due to air blow or the like because the slide valve device is cleaned after removing the refractory after use.
