A method for manufacturing a steel component from a blank is provided. Firstly, a blank is placed in a conveyor system. Then, at least a preselected zone of the blank is preheated while the blank is retained at a predetermined preheating location. Finally, the blank is conveyed through a furnace. A preheating system for heating blanks in a production line is also provided.

The present disclosure relates to a furnace roller and to a roller furnace having such a furnace roller. The furnace roller has a hollow-cylindrical roller body with an interior space. A stopper is arranged in each end-side length portion of the roller body. The stopper is composed of a geopolymer, such as an alkali-activated aluminosilicate.

A cooling roll including an axle and a sleeve, the sleeve having a length and a diameter and being structured as follows: an inner cylinder, a plurality of magnets disposed along at least a portion of the inner cylinder length, each magnet being defined by a width, a height and a length, a cooling system surrounding at least a portion of the plurality of magnets, the cooling system and the plurality of magnets being separated by a gap defined by a height, the gap height being the smallest distance between a magnet and the cooling system above, the magnets having a width such that the following formula is satisfied: gap height x 1.1 magnet width gap height×8.6.

A roller for a roller hearth furnace, the roller including a water-cooled, rotatably mounted carrying axle on which a plurality of support rings are arranged at a spacing from one another. In the axial region between and next to the support rings, the carrying axle is provided with insulation composed of a fiber material and configured with protection of the outer circumference of the fiber material from the environment. In the case of insulation constructed from ring-shaped punched parts, the insulation arranged in the axial region between and next to the support rings is composed of circular or ring-shaped punched fiber parts. The protection is configured as ring-shaped insulating disks composed of a more resistant material than that of the punched fiber parts, and at least one punched fiber part is provided in each case between two insulating disks.

A transport roller brush assembly that includes a base that is constructed to support a plurality of brush wires such that the plurality of brush wires are oriented to extend in a radial direction relative to an axis of rotation of an underlying material transport roller. The base is preferably split into at least two arcuate portions that can be removeably secured to one another preferably via cooperation of a plurality of collar or collar portions and such that the respective and preferably two arcuate portions generally circumscribe a transport roller when the base is secured thereto. Discrete brush assemblies are preferably provided in a plurality of inner and outer radial dimensions such that roller brush assemblies as disclosed herein can be used with transport rollers of various outer radial dimensions.

A vacuum coating device for a flexible substrate is provided, including a vacuum coating chamber and a transition chamber which are connected to each other. The vacuum coating chamber and the transition chamber communicate with each other through a slit. The vacuum coating device further includes a cooling roller, which is fixed in the transition chamber through a tension adjusting component. The cooling roller includes a roller body and a shaft, the roller body is fixedly installed on the shaft, and the roller body and the shaft are coaxial. Multiple heat dissipation passages are provided in the roller body along an axial direction of the roller body. Good cooling function is achieved and the flexible substrate is prevented from generating winkles.

A conveyance roller for a heating furnace includes: a roller body constituted by a metal tube made of a heat-resistant alloy; at least one holding protrusion provided on an outer circumferential surface of the roller body for holding an object to be heated in the heating furnace, and protruding from the outer circumferential surface of the roller body in a plurality of positions at a given interval in a longitudinal direction of the roller body; and at least one shielding member provided to be adjacent to the at least one the holding protrusion in the longitudinal direction, and covering the outer circumferential surface of the roller body. The at least one shielding member has a thickness not larger than a height of the holding protrusion from the outer circumferential surface of the roller body.

A furnace roller assembly having a fluid-cooled shaft that is covered by an interface performance material comprising both ceramic millboard and a wire brush bristled-material is disclosed. The roller assembly can be used as part of a conveyance system in a finishing mill to support and transport steel sheet through an annealing furnace. The fluid-cooled shaft and the ceramic millboard plus wire brush interface performance material arrangement provide the means to provide effective insulation for the shaft while preventing degradation of the covering on the shaft.

A roller transport assembly includes a cart assembly and a roller carriage assembly. The roller carriage assembly is slidably mounted to the cart assembly and has at least one chamber for housing a roller. Each of the chambers includes a linear rail extending along a first axis and a roller coupling device attached to and slidable along the linear rail. The roller coupling device is operable to couple to the roller and move the roller along the first axis adjacent and parallel with the linear rail.

A roller for a roller hearth furnace, the roller including a water-cooled, rotatably mounted carrying axle on which a plurality of support rings are arranged at a spacing from one another. In the axial region between and next to the support rings, the carrying axle is provided with insulation composed of a fiber material and configured with protection of the outer circumference of the fiber material from the environment. In the case of insulation constructed from ring-shaped punched parts, the insulation arranged in the axial region between and next to the support rings is composed of circular or ring-shaped punched fiber parts. The protection is configured as ring-shaped insulating disks composed of a more resistant material than that of the punched fiber parts, and at least one punched fiber part is provided in each case between two insulating disks.
