PURPOSE:To extend the service life of a cooling body and to improve the productivity of a quickly cooled thin strip by coating a composite material consisting of metal as matrix and embedded therein with carbon fibers, etc. as reinforcing fibers on the surface of the base material of the cooling roll. CONSTITUTION:A composite material 3 coated on the surface of a cooling body consists of metallic matrix 3a and reinforcing fibers 3b. The molten metal 5 stored in a vessel 4 for molten metal is supplied from a nozzle 6 to the part near the contact area of cooling rolls 1, 1, by which the molten metal is quickly cooled and solidified to a thin strip 7. In the case of coating the composite material on the surface of the rolls 1 by plating, the surface 2a of the cooling body of the base material 2 of the cooling roll is beforehand coated with the reinforcing fibers 3b and the metal to serve as the matrix is plated thereon. |
