行うときは、注湯の量が少量であるために、前記の影響
が更に鋳片に生じ易くなる問題がある。That is, at the start of pouring, the solidified shell formed on the continuously driven mold and the solidified shell formed on the side seal plate are integrated with each other, so that a problem such as breakage of the cast piece is likely to occur. In order to prevent this problem, conventionally, the side seal plate is heated at another position, and the heated seal plate is inserted into the continuous casting machine and installed, and then pouring is started. However, in this method, the side seal plate heated as shown by the broken line in FIG. 3 is cooled by the time it is installed in the continuous casting machine and the pouring is started. There was a problem that plate breakage, leaking of water, etc. due to abnormal growth of the. Further, at this time, when performing continuous casting of a thin plate, there is a problem that the above-mentioned influence is more likely to occur in the cast piece because the amount of pouring metal is small.
