Note that 5c is a water cooling jacket. With such a structure, the core material 13 is held between the opposing collar portions 5a, and the molten steel 12 is poured into the groove 5b closed by the core material 13 to form a pool, and both surfaces of the roll and the core material 13 are formed. During this period, molten steel can be continuously supplied and solidified.
