    Abstract: A method and apparatus for finish rolling long products such as bars, rods and the like, comprising: in a first operational mode, rolling the products through a finishing block (14) and a reducing sizing mill (20) arranged on a primary pass line (P 1 ); and in a second operational mode, diverting the products from the primary pass line to a secondary pass line (P 2 ), bypassing the finishing block and then back to the primary pass line for rolling in the reducing sizing mill. Optionally and preferably, a cooling unit (16) is shifted between the primary and secondary pass lines to cool products being rolled in each operational mode.

    Abstract: A method and apparatus for continuously hot rolling ferrous long products which employs a "post finishing" block of roll stands downstream from the finishing stands of the mill. Water boxes or other like cooling devices are preferably interposed between the last mill finishing stand and the postfinishing block. The post finishing block includes at least two reduction stands followed by at least two sizing stands. The reduction stands have an oval-round pass sequence, and the sizing stands have a round-round pass sequence. Clutches or other equivalent means are employed in the drive train to permit changes to be made between the interstand drive speed ratios of at least the reduction stands, and also between some or all of the remaining sizing stands. A fixed rolling schedule is provided for all roll stands in advance of the finishing stands. Thus, the finishing group is supplied with a first process section having a substantially constant cross sectional area and configuration. The first process section is passed through the finishing group and rolling occurs in either none, some, or all of the finishing roll stands, depending on the size of the desired end product. The product then continues through water cooling boxes to the post finishing block as a second process section. The interstand drive speed ratios of the roll stands in the post finishing block are appropriately adjusted to accommodate rolling of the second process section. The total reductions affected in the initial reduction stands of the post finishing block are well above 14%, thereby producing an increased energy level in the product sufficient to create a substantially uniform distribution of fine grains. Typically, such total initial reductions will be on the order of about 20-50%. Significantly lighter reductions on the order of 2-15% are taken in the final round-round pass sequences of the post finishing block to obtain the desired close sizing tolerances in the finished product. The time interval between the higher reduction affected in the oval-round pass sequence and the lighter reductions affected during sizing in the round-round pass sequence is such that the resulting grain size throughout the product cross section will not vary by more than 2, and in most cases by less than 1 ASTM grain size number.

    Abstract: The invention relates to a method for reverse thermomechanically rolling an aluminium plate in a rolling process involving a plurality of rolling passes. In the method, identifying data (4) are determined for thermally guiding the rolling process; a value of a state variable (3), from which a temperature of the aluminium plate can be deduced, is continuously measured, and a pass schedule (5) is determined for the rolling process on the basis of the value of the measured state variable (3) and of the identifying data (4). The pass schedule (5) provides for a rolling pause between at least two successive rolling passes, during which rolling of the aluminium plate is interrupted for cooling purposes.

    Abstract: The invention relates to a roller table (1, 1') for transporting a rolled product (5, 5') in a rolling train, wherein the roller table (1, 1') comprises at least two drive segments operated via converters (2a, 2b). According to the invention, at least one sub-segment (c) of the roller table (1, 1') can be switched by means of a switchover unit (3) on a first converter (2a) and/or on a second converter (2b). According to the invention, the rolling train is made more flexible compared to known solutions while having the same number of converters.
