Beschreibung
Zusammenfassung:	Provided is a high-temperature metal cooling method which, without using a device having a complicated configuration, improves cooling performance and enables uniform cooling by means of an injection liquid. The high-temperature metal cooling method according to the present invention is characterized by comprising cooling a high-temperature metal that is being conveyed, with a microbubble-containing cooling liquid by supplying the cooling liquid toward the high-temperature metal. Se proporciona un método de enfriamiento de un metal a alta temperatura por un líquido de rocío que puede mejorar suficientemente la capacidad de enfriamiento y conseguir un enfriamiento uniforme sin necesidad de utilizar un dispositivo de una estructura compleja . El método de enfriamiento de metal a alta temperatura comprende suministrar un refrigerante que contiene microburbujas a un metal a alta temperatura que se transporta, para enfriar el metal a alta temperatura mediante el refrigerante.
