Abstract

PURPOSE:To prevent reduction in breadth of water membrane in lateral direction of a nozzle so as to cool steel plate uniformly by making the sectional area of cooling water slit nozzle for steel plate cooling apparatus agree with, or smaller than, the sectional area of water flowing down within the nozzle.
