が低下するため、多連鋳化は連続鋳造にとって大きなメ
リットとなる。That is, the more the continuous casting is performed, the more the operating rate is dramatically improved, and the yield is improved because the ratio of the crop cutting loss at both ends is reduced. Also, regarding the material cost of refractory materials, since the amount of steel passing through a single material increases and the basic unit decreases, multiple casting is a great advantage for continuous casting.

片と鋳片をつなぐための連結用治具の挿入を必要とす
る。In order to carry out this multiple casting, it is necessary to quickly replace the ladle or tundish, and it is also necessary to insert a connecting jig for connecting the cast pieces.
この鋳片連結用治具は鋳片と鋳片の境界部に挿入する
もので、取鍋あるいはタンディッシュの交換時に鋳型内
溶鋼に一部が浴面より露出するように浸漬挿入する。This slab connecting jig is inserted at the boundary between the slab and the slab, and when the ladle or the tundish is replaced, it is immersed and inserted in the molten steel in the mold so that a part thereof is exposed from the bath surface.
この鋳片連結用治具の挿入は、従来人力で行なわれて
おり、重筋作業であるばかりでなく、場所的に非常に危
険な作業でもあり、機械化、自動化が望まれていた。The insertion of the slab connecting jig is conventionally performed manually and is not only a heavy-duty work but also a very dangerous work locally, and mechanization and automation have been desired.
