Rail-manufacturing equipment that performs forced cooling on at least a head of a hot rail hot-rolled at or heated to the austenite region temperature or higher. The rail-manufacturing equipment includes a head-cooling header configured to jet a cooling medium toward the head of the rail, a head thermometer configured to measure surface temperature of the head of the rail, and a controller configured to adjust jet of the cooling medium from the head-cooling header. The controller includes a temperature-monitoring unit configured to monitor measurement results by the head thermometer during the forced cooling, and a cooling-rate controller.

A cooling bar (1) for cooling rolled material (5) being moved in a transport direction (3) and in particular for reducing temperature differences in the temperature of the rolled material (5) transversely to the direction of transport (3). The cooling bar (1) has several full jet nozzles (11) by means of which a coolant beam of a coolant with an approximately constant jet diameter can be distributed to the rolling stock (5) in the direction of distribution (15). A cooling device has at least two cooling bars (1) of that type. The cooling bars extend transversely to a transport direction, one behind the other. Each cooling bar has a respective different pattern of jet nozzles and selection of applicable pattern of jet nozzles in their respective bars selectively cools the rolled material transversely to the transport direction.

Provided are an oil removal system and an oil removal method with which good oil removal can be achieved, and a superheated steam generation device which can be used in the execution thereof. An oil removal device imparts, from a discharge part, superheated steam obtained by a superheated steam generation device to a treatment object, which includes oil on the surface thereof. The treatment object is set so that the surface temperature thereof is cooled by a cooling part so as to be lower than the superheated steam. Dew condensation is produced on the surface of treatment object by the discharge of the superheated steam from the discharge part, and the dew condensation is blown off and removed from the surface of the treatment object by a removal part, and thereby oil on the surface is removed together with the dew condensation.

A rolling mill includes a frame, at least one pair of working cylinders capable of defining the air gap of the strip to be rolled, as well at least one line for spraying a lubricant and/or coolant fluid, arranged next to the plane of the strip to be rolled. The line is rigidly connected to the frame via a hinged mechanical link, the mechanical link including a resilient unit forcing the line into at least one operational position, toward the plane of the strip, and allowing, in the event that a force on the line tends to separate the line, greater than a threshold value, the deformation of the resilient unit against the return force thereof, and thus the retraction of the line toward a position separated from the at least one operational position.

A plurality of water removing nozzles of a water removing apparatus comprise one or more of a single far water removing nozzle and a far water removing nozzle group. The single far water removing nozzle forms a far end water removal single area that does not include one end but includes the other end in the width direction of a steel sheet conveyance plane. The far water removing nozzle group forms the far end water removal single area and one or more inner water removal single areas that do not include either end in the width direction of the steel sheet conveyance plane, in such a manner that the far end water removal single area and the one or more inner water removal single areas are aligned in order from the one end side to the other end side while overlapping with each other in the width direction of the steel sheet conveyance plane and aligned in order from the upstream side to the downstream side without overlapping in the conveyance direction.

The invention concerns a method for cold rolling bright aluminium rolled products and comprises: (a) Providing a first aluminium alloy rolled product (b) Rolling said first product with a rolling mill (1) having at least one work roll ground to a finish (11), with a roughness Ra less than 1 m, and using a rolling lubricant (51) from a first container (2) comprising less than 150 mg/L of aluminium debris to obtain a second aluminium rolled product having at least one bright surface, (c) Transferring at least a portion of said rolling lubricant to a second container (3) (d) Filtering the lubricant from said second container (52) by using cross flow filtration (4) through a membrane (41), to obtain a cleaned rolling lubricant (54) comprising less than 10 mg/L and preferably less than 5 mg/L of aluminium debris preferentially having a mean diameter of less than 2 m, (e) Returning said cleaned rolling lubricant (54) to the first container.

A hybrid rolling mill includes at least one work stand and a lubrication system. The at least one work stand includes an upper work roll and a lower work roll. The lubrication system includes a first lubricant applicator and a second lubricant applicator. The first lubricant applicator is configured to supply a first lubricant at an entry side of the work stand in a first rolling mode. The second lubricant applicator is configured to supply a second lubricant at the entry side of the work stand in a second rolling mode.

Provided herein are systems and methods for removing a viscous material from a material article. In particular, a viscous material removal system can include a seal and a biasing mechanism. The viscous material removal system can also serve as a viscous material containment system. The systems can provide viscous material removal from planar and non-planar articles, as well as articles having surface irregularities or a topography including ridges and valleys. A method for removing viscous materials can include contacting the seal to the material article, maintaining contact of the seal across a width of the material article via the biasing mechanism, and passing the material article over the seal, thus removing the viscous material from the material article.

Provided herein are systems and methods for containing a viscous material, such as a coolant, on a roll and/or a roll processed engineering material (e.g., a metal strip). In particular, a viscous material containment system can include a movable seal and a gas delivery device. A method for cooling a roll can include applying a viscous material, such as a coolant, to the roll and containing the viscous material on the roll using the viscous material containment system. In some cases, the viscous material containment system can be used to facilitate removal of the viscous material from the roll and/or the roll processed engineering material.

Systems and methods of quenching a metal substrate include cooling a top surface and a bottom surface of the metal substrate until a strip temperature is cooled to an intermediate temperature. Cooling of the top surface of the metal substrate is discontinued when the strip temperature reaches the intermediate temperature, and cooling of the bottom surface of the metal substrate continues until the metal substrate reaches a target temperature, where the target temperature is less than the intermediate temperature.
