COOLING ROLL OF THIN SLAB CONTINUOUS CASTING MACHINE |
摘要 |
PROBLEM TO BE SOLVED: To extend life of a roll and to prevent generation of crack of a slab by efficiently arranging recessed parts of prescribed depth on the peripheral face of a cooling roll of a continuous casting machine to produce a thin slab and preventing deformation and wear of the recessed parts. SOLUTION: In a cooling roll 6 of a continuous casting machine to produce a thin slab, a Ni layer 9 and Co layer 10 of 10-500μm thickness are formed in sequence on the peripheral face of the cooling roll 6, a sum of thickness of the Ni layer 9 and Co layer 10 is 500μm-2mm, recessed parts (d) having 30-150μm average depth are formed on the surface of the Co layer 10.
