鋳込み方向の振動（垂直振動）を与えることが一般的に
行われている。l. 3. Continuous casting involves pouring molten steel into a bottomless mold, coating the surface of the molten steel in the mold with powder, and performing primary cooling within the mold.
It is then solidified by primary cooling in the group of Guy 1/' rolls,
This is a method of manufacturing slabs by drawing them with drawing rolls. In order to avoid damaging the surface of the mold by the pulled slabs, the mold is lowered according to the speed at which the slab is pulled out, and then returned to its original position. It is common practice to raise the mold and repeat this process to apply vibrations in the casting direction (vertical vibrations) to the mold.

より高連鋳込を阻外する一因となっていた。Scene coating powder suppresses oxidation caused by contact between the molten steel surface and air, captures inclusions, etc., and also prevents rapid cooling of the surface of the slab due to the molten layer flowing into the gap between the slab and the mold. However, conventional vertical vibration alone deteriorates the quality of the slab due to insufficient penetration of the powder into the gap between the slab and the mold, and also causes breakouts due to seizure between the mold copper plate and the slab. In addition, corrosion of the copper plate of the mold, etc., was a factor that prevented continuous casting.

止には効をなさない。In order to solve this problem, in addition to the normally used oscillation device that only uses rectangular vibration, we installed a vibrator on the long side frame of the mold to vibrate the entire mold in a direction perpendicular to the casting direction. Horizontal vibration) has been considered, but in this case, not only the mold but also the molten steel and powder inside the mold are vibrated, so it is not effective in preventing poor powder penetration.

形或するのがよい。Since only the long side frame 4 vibrates horizontally in the opening/closing direction, the molten steel and powder in the mold do not vibrate horizontally, so the powder can be well melted into the gap formed between the side of the molten steel shell in the mold and the long side copper plate. can be set. From the viewpoint of cooling shrinkage of the slab, it is preferable to close the long side frames 4 when the mold 1 descends, and open the long side frames 4 when the mold 1 rises to form a gap.
