Abstract. Toll services have been increased recently in the Japanese HIP market. This trend leads to larger HIP equipment and shorter cycle times for productivity improvement. In addition, longer life cycle of pressure vessels are demanded to reduce the costs in conformance with the requirements of the relevant laws and regulations of Japan. To meet such demands, KOBELCO has developed a new rapid cooling system and the first product was delivered in 2016. This new cooling system ensures a rapid cooling rate while achieving the design life cycle by low design temperature of the pressure vessel. At the development stage of the new cooling system, the numerical analysis of the heat flow during rapid cooling was conducted using new techniques including a real gas model and a new model for the thermal insulator. This article will introduce this new rapid cooling system and describe other related topics.
