PURPOSE: A cooling apparatus for an H-beam rolling line is provided to reduce temperature differences of a product by lowering the entry temperature of an H-beam to a cooling bed. CONSTITUTION: A cooling apparatus for an H-beam rolling line comprises an intermediate cooling unit(110) which is formed between intermediate rolling mills to cool an H-beam, concentrating the middle portion of the flanges of the H-beam in an intermediate rolling process, and a rapid cooling unit which rapidly cools the H-beam in whole after the completion of a finish rolling process. The intermediate cooling unit comprises a cooling chamber, a plurality of cooling water inlets(114) formed in the cooling chamber to let cooling water in, and a plurality of nozzle holes(H1,H2) formed in the cooling chamber to spray cooling water in the cooling chamber to the flanges of the H-beam.
