Hot slabs after the slabbing mill are at a mean temperature of 1000℃ and have the sensible heat of 160×10^3 kcal/t-slab. The main features of a Slab Cooling Boiler (SCB) are the recovery of the sensible heat to steam (16kg/cm^2G) by mean of heat radiation from the surface of hot slabs, and continuation of cooling process of almost every kind of slab. The first installation of an SCB was completed at Slabbing Mill No.2 in Mizushima Works of Kawasaki Steel Corporation and it has been operating successfully since March, 1976. The capacity of the heat recovery in this SCB is 72000kcal/t-slab. It is equal to or greater than the heat consumption of rimmed and semikilled steel in the soaking pit. This paper discusses the basic heat transfer experiments performed under this development, the basic planning of the installation, the outlines of the system, and some results of the operations.
