The invention relates to a cast-rolling roller of a rolling mill with high binding resistance and high crack-diffusing resistance, and a process for manufacturing the same. The process comprises the following steps of: (1), putting a waste molten metal (a), an alloying element (b) and a plurality of chips (c) into a melting furnace; (2), melting the loaded materials at the temperature of between 1,200 and 1,500 DEG C; (3), performing chemical pre-analysis on a sample (d) of the loaded materials; (4) regulating the chemical components (by adding an iron alloy or a pure metal (e)); (5), adding sulfur (f) into the loaded materials; (6) performing another chemical pre-analysis on a new sample (g) of the loaded materials; (7) regulating the chemical components (h); (8), adding at least one rear earth metal (k) into a casting ladle (j); (9), transporting the molten metal from the melting furnace to the casting ladle (j); (10), transporting materials in the casting ladle to casting equipment; and (11) forming a half-finished product of the roller. |
