ABSTRACT:
A method envisaging the use of a movable stand with shaped rolls featuring a working portion with the reversible rotation of said rolls being limited by an angle encompassing said working roll portion, and the rolling of an ingot being cast is effected by carrying the stand with the rotating rolls "forward" -- "backward".
With a stable rolling process the rolling cycle comprises the following steps: setting the rolls with their working portions to one of their extreme positions, carrying the stand with the standing rolls "backward" in the direction opposite to that of the ingot being cast into a position corresponding to the next reduction of the ingot, reducing the ingot between the rolls with the stand carried "backward," setting the rolls with their working portions to another extreme position, displacing the stand with the stopped rolls "backward" at a distance which is the function of the assigned shrinkage during the next "forward" stroke of the stand, reducing of the ingot between the rolls with the stand moving "forward," carrying the stand with the stopped rolls "backward" at a distance which is the function of the assigned shrinkage during the next "backward" stroke of the stand. Next the "backward" -- "forward" strokes are repeated until an ingot portion extracted from the mould over the withdrawal period is rolled out, whereafter the movable stand with the stoppeding rolls is carried "forward" at a distance equal to the ingot length extracted from the mould over the withdrawal period. Further, after the next extraction of the ingot being cast from the mould the rolling cycles are repeated for the next portions of the ingot being extracted from the mould. To provide the reciprocation of the stand and reversible rotary motion of the rolls the rolling mill is equipped with a gear made as hydraulic rams mounted on the movable stand and to ensure the displacement of the stand when the work rolls do not interact with the ingot being rolled the mill is furnished with the second transfer gear.
