Embodiment 1
[0048] The E2 vertical roll is produced by the above process, and its specifications are: φ1360×720×2875mm. The specific forging process is as follows:
[0049] S11: Ingot heating, the heating temperature range is 1210-1230°C.
[0050] S12: out of the furnace, the whole ingot is upsetting H≤1200mm, and the FM method is drawn to 1200mm 2 , return to the furnace for homogenization, the homogenization temperature is 1220°C, and the time is 10h to obtain one upsetting and one drawing billet;
[0051] S12: out of the furnace, upsetting H≤1100mm, FM method drawing to 1400mm 2 , and then flatten the anvil and pull it to 1200mm 2 , return to the furnace for homogenization, the homogenization temperature is 1200 ° C, and the time is 2 to 4 h to obtain two upsetting and two drawing billets;
[0052] S13: out of the oven, upsetting H≤1100mm, FM method drawing to 1400mm 2 , and then flatten the anvil and pull it to 1200mm 2 , return to the furnace for homogenization, the homogenizatio...
