Abstract: A high-speed shear for transversely cutting rolled strip with knife carriers which can be driven for rotation and are arranged in pairs opposite each other. The knife carriers are supported on shafts of gear wheels arranged at a fixed axial spacing in pairs opposite each other in a shear cassette. The shear cassette is mounted within an outer frame and the shear cassette is provided with a lifting device for raising or lowering the shear cassette within the outer frame. In a method for operating the shear, the two knife carriers are moved into a horizontal position for allowing the strip end to enter or travel through, and the shear cassette is moved within the outer frame into a raised transfer position.

Abstract: A high-speed shear for transversely cutting a rolled ship having a small thickness and including at least one blade provided on one of two oppositely located drums, and a controllable device for displacing the two drums between a cutting position, in which the strip is cut, and an open run-through position in which the strip can be freely advanced between the two drums, with the two drums being synchronized in their open cutting position by respective tooth elements provided on the two drums and engaging each other, and with the tooth elements being so formed that they insure synchronization in the open position of the drums when they engaged each other with, a large tooth backlash and engaged each other substantially backlash-free in the cutting position of the drums.

Abstract: A continuous casting method and apparatus in which a distributor deposits a strand of molten steel upon a cooled surface of casting roll to a thickness of 1.0 to 6.0 mm, the cooling strand passes through the nip or gap between a fist counterroll and the casting roll and hardening strip is then passed through at least a first further nip between one or more further counterrolls and the surface of the casting roll. The height of the molten metal in the distributor is controlled to be constant by detecting the surface of the melt and regulating the outflow from an intermediate receptacle into the distributor and/or from the casting ladle into the intermediate receptacle so that the peripheral speed of the casting roll is matched to the speed with which the strand emerges from the distributor onto the casting roll.

Abstract: A high-speed shear for transversely cutting rolled strip with knife carriers which can be driven for rotation and are arranged in pairs opposite each other. The knife carriers are arranged with a fixed distance between each other on both sides of the strip in a common shear cassette. The shear cassette is mounted within an outer frame and the shear cassette is provided with a lifting device for raising or lowering the shear cassette within the outer frame. In a method for operating the shear, the two knife carriers are moved into a horizontal position for allowing the strip end to enter or travel through, and the shear cassette is moved within the outer frame into a raised transfer position.
