力の向上が制約される。This type of method is the subject of a prior patent application currently pending (unpublished). The method of carrying out most of the entire deformation process on the return stroke of the roll stand is already in practical use and has been used to significantly increase the production capacity when rolling pipes, as well as to significantly improve the tolerances of the product. However, the disadvantage of the above-mentioned prior invention compared to the conventional technology is that during the deformation process, the maximum horizontal rolling force that causes the ingot to come into contact with the stationary feed slide increases significantly. It is recognized that this is true. This rolling force limits possible deformation in the return stroke, which limits the improvement in production capacity.

である。Based on the above-mentioned problems and knowledge, an object of the present invention is to significantly reduce the maximum value of the elongation force, thereby reducing the load on the feed mechanism, which has been hitherto methodically constrained. The aim is to remove the limitations on production capacity that had previously existed.

成されたのである。According to the present invention, when rolling an ingot in the backward stroke of the a-roll stand, the horizontal reverse rolling force reaches a maximum value in a part of the chrysanthemum-shaped processing area of the pull bar and is constant. This was achieved by pulling and moving the inbot 1 backwards a distance of .

と理論的な研究とにより実証されている。As a result of experimentally adopting the method according to the present invention, we found that 2 to 8[
It has been revealed that when the feeder slide is pulled backward, the maximum value of the reverse rolling force can be reduced by about 70% compared to the value measured when the present invention is not applied. Ta. Moreover, with the implementation of the method according to the invention, the deformation area in which the ingot is pulled backwards can be necessarily reduced, which in practice does not lead to drawbacks such as cracks. Proven by measurements and theoretical studies.

る。Furthermore, the apparatus for carrying out the method of the invention may include a pre-biased spring element or similar means for storing mechanical force between the ingot and the feed slide or feed drive mechanism to control the rearward pulling movement of the ingot. A device is proposed which is characterized in that it is provided between. And when the rolling force is moderately large, compressing the spring element with K
This makes it possible to pull the ingot backwards by a predetermined distance depending on the spring properties of the spring element.

の知見に従って変更することを意味している。As another device for carrying out the method of the invention, it is proposed that the means for controlling the movement of the ingot are constituted by suitable means such as a cam disc, etc., in order to mechanically control the backward pulling movement of the ingot. . This means that, in accordance with the findings of the present invention, the feed drive mechanism of the ingot feed slide is modified so that the ingot can be mechanically moved backwards within the deformation processing region where the maximum value of horizontal rolling force can be expected. It means to do.
