防止機能および自己潤滑機能の両方を備えている。The baked VJ earthen plate 4 attached to the inner surface of the support cooling member 11 is made of a so-called cerment-based material, which is a high melting point metal eutectoided with graphite, molybdenum disulfide, boron nitride, etc., and has a thickness of 1. It is composed of a thin plate with a thickness of .oms or less, and has both a function of preventing burning of the solidified shell and a self-lubricating function due to the combined effect of a high melting point metal and a eutectoid.

い。The unsolidified slab 12 cast in this manner is continuously pulled out from the nozzle 2 in synchronization with the upper and lower endless belts 5. At this time, the unsolidified slab 12 in scraping contact with the anti-seizure plate 14 of the support cooling section 1'], 1 smoothly slides on the anti-seizure plate 14 due to the self-lubricating function of the anti-seizure plate 14, thereby preventing seizure. No phenomenon occurs. Therefore, no breakout will occur.
