Abstract: PURPOSE: To decrease the temp. differences between the flange parts and the web parts of shapes and effectively cool the flange parts by providing side guides with water dispersion plates having water permeability in the positions of the through-holes formed at these side guides corresponding to the fillet parts of the shapes. CONSTITUTION: The cooling water which is injected from spray nozzles 10 and passes above and below the water dispersion plates 11 passes the through- holes 8 without coming into contact with the water dispersion plates 11 and arrives at the upper parts and lower parts of the outside surfaces of the flange parts 2 which are areas to be cooled. On the other hand, the cooling water which is injected from the spray nozzles 10 and cools the central parts of the flange parts 2 partly passes the mesh openings of the water dispersion plates 11 so as to arrive at the fillet parts 5 and partly collides against the members constituting the water dispersion plates 11 thereby widely splashing and arriving at the flange parts 2. Thereby, the pattern of the cooling water is formed to a cruciform to enlarge the areas to be cooled.  The cooling capacity of the upper and lower parts of the flange parts 2 is controlled by changing the patterns of the water dispersion areas.
