A cut-to-length steel coil processing line has an un-coiling reel, a temper mill, a stretcher leveler, a shearer, and a stacking apparatus arranged to sequentially process a continuous length of sheet metal. The line may be configured such that the continuous length of the sheet metal is directed from the uncoiling reel through the temper mill to the stacking apparatus without processing through the stretcher leveler when a determined thickness of the continuous length of sheet metal is at or below a selected measurement criteria. In the alternative, the line may be configured such that the continuous length of the sheet metal is directed from the uncoiling reel through the stretcher leveler to the stacking apparatus without processing through the temper mill when the determined thickness of the continuous length of sheet metal is greater than the selected measurement criteria.

A method and a device that bridge an interruption in production in a combined casting-rolling installation to provide a combined casting-rolling installation for producing a hot-rolled finished strip, in which, in the case of an interruption, also thick precursor material having a thickness of >30 mm can be separated in a rapid and reliable manner from the next precursor material.

The present invention relates to an intermediate blank connection system for hot-rolled strip headless rolling and a connection method, and belongs to the technical field of intermediate blank connection for strip steel headless rolling. The connection system and the connection method realize matching of an intermediate blank connection device and speed of a unit through a translation drive system. A mounting frame is used to provide support for cutting devices, and the cutting devices are divided into two groups arranged in the mounting frame to achieve clamping of a front slab and a rear slab respectively. Interlaced dovetail cutting edge structures are used to achieve cutting and ensure a good longitudinal stress state. Finally, a certain difference is set in sizes of width directions between cutting edges, to ensure that there is certain extrusion deformation in a process of forming dovetail cutting groove connection, and enhance a connection effect. At the same time of realizing a good intermediate blank connection effect finally, a structure of the connection device is greatly simplified, and investment and operating cost is reduced.

A combined casting and rolling installation and to a method for operating the combined casting and rolling installation. The combined casting and rolling installation comprises a rough-rolling mill train, a discharging device, a first transporting device, a quenching device, and at least one severing device. The rough-rolling mill train is configured to roll a continuously cast hot billet to form a rough-rolled strip. The discharging device is downstream of the rough-rolling mill train with respect to a conveying direction of the rough-rolled strip. The severing device is between the rough-rolling mill train and the discharging device and cuts up a first sub-portion of the rough-rolled strip into a rough-rolled strip piece. The discharging device discharges the rough-rolled strip piece. The first transporting device connects the severing device to the quenching device and transports the rough-rolled strip piece to the quenching device, which is configured to quench the rough-rolled strip piece.

The track shoe assembly may also include a grouser having a grouser body having a grouser attachment surface, and at least two tabs, integrally formed with the grouser body, the at least two tabs extending from the grouser attachment surface, and perpendicular to the grouser attachment surface, the at least two tabs of the grouser being configured to be positioned within the at least two slots of the shoe plate. In another aspect, a method of manufacturing a track shoe assembly may include forming a shoe plate as described above, forming a grouser as described above, and attaching the grouser to the shoe plate to thereby form a track shoe assembly.

Coils of sheet metal and individual sheets of sheet metal having a thickness of greater than 0.074 inches are descaled in a processing line. The processing line has a cut to length portion, a conveyor, a destacker, and an apparatus for descaling the sheet metal by propelling one of grit and slurry against the sheet metal using an impeller wheel. The descaling apparatus has pinch rollers in an interior of the descaling apparatus. The processing line is configurable for processing a coil format by directing the sheet metal from the cut to length portion of the processing line through the descaling apparatus via the conveyor without processing through the destacker. The processing line is alternatively configurable for processing individual sheets of the sheet metal by directing the sheet metal from the destacker through the descaling apparatus via the conveyor without processing in the cut to length portion.

In the case of a production plant which comprises in series a thin-slab continuous casting plant (1), which is arranged upstream of a roller hearth furnace (2), the roller hearth furnace (2) and a rolling mill (3), which is arranged downstream of the roller hearth furnace (2) and has an assigned reeling plant (21), wherein the continuous casting plant (1) and the rolling mill (3) can be operated in a continuous operating mode, the intention is to provide a solution that allows a slab buffer capacity to be provided for a continuously operated thin slab continuous casting plant when there is a fault causing a standstill in the transport of the slab or strip. This is achieved by the production plant having four slab or strip cutting devices (10, 14, 17, 24), which are arranged upstream and downstream of the roller hearth furnace (2), in a section along the length of the roller hearth furnace (2) and on the outlet side of a first separate roll line (12) of the rolling mill (3).
