| description | The invention discloses an oblique cube and chamfered steel avoiding rolling method for a cylinder-shaped electro slag steel ingot with the taper. The method comprises the following steps that firstly, hole patterns are designed, box type holes are adopted in all the hole patterns, three to five rolling grooves are designed, the notch size BK of the first groove is larger than the size of a maximum original blank by 100 mm-150 mm, the groove bottom size bk is reduced by 5 mm-10 mm compared with the notch size BK, and the groove depth HK is equal to 60 mm; the notch size BK of the second groove is larger than the size of a process rolled piece by 30 mm, the groove depth HK ranges from 160 mm to 200 mm, the groove bottom size bk is consistent with the size of the rolled piece, and the other rolling grooves are designed according to the common hole pattern design knowledge; and secondly, rolling of the first groove, the second groove and other grooves is conducted. The method has the beneficial effects that unde |
