A method has been proposed for using a blooming mill to roll semifinished products from big-end-down ingots of rimming and semikilled steels. In particular, the method can be used for alternatively charging ingots into the mill by the front end and the back end. Each ingot is rolled in several passes each on its face and on its edge. The initial pass made with the ingot face flat is done in such a way that the large base of the conical ingot is reduced first. The largest possible reductions are made in this case. The reductions are made as small as possible when the ingot is turned so that its small base enters the stand first. This is done so as to stably transfer rolled metal to the other side of the mill. Use of the method increases the productivity of blooming mills and lowers consumption coefficients. I. A. Sharapov, V. V. Dorofeev, V. I. Pribytkov, et al.

The method involves an initial heating, a first-stage extrusion of the distilled calcium to obtain semifinished products, a second heating, and a second-stage extrusion in the continuous regime. The successively fed semifinished products are welded together during the second extrusion operation. The outside surface of the distilled calcium is conditioned before the first heating, which entails heating the calcium to a temperature no higher than 0.12 of its melting point. In the second heating, the material is heated to a temperature no greater than 0.18 of its melting point. The first extrusion is done with an extrusion ratio of at least six, and during this operation the calcium is kept at a temperature no higher than 0.18 of its melting point. The second extrusion is done with an extrusion ratio of 130-200. Temperature in this operation is kept at a level no greater than 0.25 of the melting point of calcium. Both extrusions are done through a one-channel die, and the conditioning of the surface is performed with a metal brush. The method improves the mechanical characteristics of the sections of the wire that are welded in the deformation zone, increases the number of gages of wire that can be made by allowing the production of wire thinner than 10 mm, and increases the productivity of the manufacturing operation.

机译：已经提出了一种方法，该方法使用大方坯轧机来轧制大边倒角钢和半镇静钢锭的半成品。特别地，该方法可以用于通过前端和后端交替地将铸锭装入磨机中。每个铸锭在其表面和边缘均经过多次轧制。铸锭表面平坦的初始加工是通过首先减小圆锥形铸锭的大底进行的。在这种情况下，最大可能的减少量。当转动钢锭时，应将其尺寸减小得尽可能小，以使其较小的底部首先进入机架。这样做是为了将轧制的金属稳定地转移到轧机的另一侧。使用该方法可以提高大方坯轧机的生产率，并降低能耗系数。 I.
