| titleOfInvention | Process for the production of rolling mill cast rolls and a rolling mill cast roll |
| abstract | The present invention is directed to a rolling mill cast roll with a higher resistance to adhesion and propagation of cracks, and the process for the manufacture thereof, said process comprising the steps of: introduction ( 1 ) of waste liquid metal (a), alloy elements (b) and a lot of scrap (c) into a melting furnace; next, melting ( 2 ) of the load at about 1,200° C. to 1,500° C.; next, chemical pre-analysis ( 3 ) of a sample (d) of the load in order to correct ( 4 ) the chemical composition (through the addition (e) of iron alloys or pure metals); next, addition ( 5 ) of sulfur (f) to the load and another chemical pre-analysis ( 6 ) of a new sample (g) of the load in order to correct ( 7 ) the chemical composition (h) is made; next, addition ( 8 ) of at least one rare earth metal (k) to the foundry ladle (j); transfer ( 9 ) of the liquid metal (i) from the melting furnace to the foundry ladle (j); and finally transfer of the content of the foundry ladle to the casting equipment ( 10 ), thus forming the semi-finished roll ( 11 ). |
