| titleOfInvention | Rolling roll manufactured by process of dissimilar materials joint and pressure-impregnation and method of manufacturing the same |
| abstract | The present invention relates to a rolling roll manufactured using a dissimilar material bonding and pressure impregnation process, and a method of manufacturing the same, and more particularly, forming a preform having a hollow part from a powder including TiC; Filling the preform into a cavity provided in the impregnation mold to form an outer layer part; Inserting steel into the hollow part of the preform to form an inner layer part; A base material filling step of filling a base material on an upper portion of the preform filled in the cavity; And pressing and preliminary impregnating a dissimilar material in which the base material is impregnated into the preform by pressing the preform, the base material and the steel, and the preform and the steel are joined. According to the present invention, the steel impregnated with the outer layer portion of the press-impregnated base material and the preform during the pressure impregnation process prevents the movement of the base material to the hollow part, and can produce a roll roll having excellent workability and low cost. . |
