Abstract: A crop prediction system performs various machine learning operations to predict crop production and to identify a set of farming operations that, if performed, optimize crop production. The crop prediction system uses crop prediction models trained using various machine learning operations based on geographic and agronomic information. Responsive to receiving a request from a grower, the crop prediction system can access information representation of a portion of land corresponding to the request, such as the location of the land and corresponding weather conditions and soil composition. The crop prediction system applies one or more crop prediction models to the access information to predict a crop production and identify an optimized set of farming operations for the grower to perform.

Abstract: The invention relates to a measuring device, a roll stand and a method for detecting the height of a roll gap between two working rolls in the roll stand. In order to ensure a high level of measurement accuracy of the roll gap transmitter even in the case of horizontal displacement of the working rolls in or against the rolling direction it is proposed in accordance with the invention to carry out adjusting the movement of the roll gap transmitter (110) with respect to the working rolls in the case of a displacement in or against the rolling direction so that even in a new or displaced end position of the working rolls a suitable relative position, which is required for a high level of measurement accuracy, between roll gap transmitter and the working rolls is guaranteed.

Abstract: The invention pertains to a rolling device (1) with at least two rolls that are respectively supported in a roll stand (3) by means of chocks (2), wherein the rolls are provided with axial displacement means (4) that serve for the axial displacement in a displacing direction (x) and make it possible to move the rolls into a desired position relative to the roll stand (3), as well as to hold the rolls in this position, and wherein the rolls are functionally connected to bending means (5) that make it possible to subject the rolls to a bending moment. In order to maintain the bending force losses caused by the weight of the axial displacement means at a minimum, the invention proposes that a first functional end (6) of the axial displacement means (4) is arranged on the roll stand (3) directly or indirectly by means of an articulated connection (7) and a second functional end (8) of the axial displacement means is arranged on the chock (2) by means of an articulated connection (9).

Abstract: A guiding device for the chocks of work rolls of a rolling stand comprising guides arranged fixedly or horizontally movably on the inner sides of the windows of the rolling stand, wherein the upper and lower bending blocks of each side are respectively assigned two guides arranged parallel to each other. Each bending block is assigned one of the guides, while it has a recess for the parallel running guide that extends around said guide, wherein the upper bending block is guided on one of the parallel guides and the lower bending block is guided on the other guide.

Abstract: A device for changing pairs of work rolls and/or pairs of backup rolls of roll stands, wherein the rolls are each supported in chocks and are movable out or in by a lower back up roll supported on a track and wheels. The work rolls on the drive side of the roll stand can be coupled to a hydraulic piston-cylinder actuator that is dimensioned in is stroke length for the removal or installation distance and can be uncoupled when it has been withdrawn by the required distance. A roll changing frame can be coupled to the actuator and, when the upper backup roll and the roll changing frame are supported on the lower backup roll, the pair of backup rolls can be moved out or back in. The actuator is coupled to a pusher with connecting arms aligned with ends of the rolls. The actuator is arranged on the drive side of the roll stand and is coupled to the pusher through a piston rod.

Abstract: The invention relates to a method and a device for changing pairs of working rolls (2) and/or pairs of back-up rolls (3) on roll stands (1), wherein a linear drive (7) for chocks (4) that are guided in supporting planes, in a direction perpendicular to the rolling direction, induces the pair of working rolls (2) mounted in the chocks (4) to withdraw or insert, and wherein a linear drive (7) withdraws or extends the pair of back-up rolls that is supported on a roll changing frame (11). In order to save time and effort, the pair of working rolls (2), after coupling to the linear drive (7) is extended and decoupled, and the same linear drive (7) is coupled to a roll changing frame (11) that is withdrawn between the back-up rolls (3a, 3b) and, when the roll changing frame (11) and the upper back-up roll (3a) are supported on the lower back-up roll (3b), is extended or withdrawn as a single unit.
