A method of cooling a rolled stock and including providing a cooling bed having entrance, middle, and end sections, transporting the rolled stock along the cooling bed in a direction transverse to the rolled stock longitudinal axis, air-cooling of the rolled stock in the entrance section of the cooling bed, spray-cooling of the rolled stock in the middle section of the cooling bed by spraying water onto the rolled stock, and air-cooling and air-drying of the rolled stock in the end section of the cooling bed.

Method of cooling a rolled stock and a cooling bed for effecting the method

An apparatus for the controlled cooling of hot-rolled sections, particularly beams, directly from rolling heat includes cooling sections or zones, wherein, seen with respect to the section to be cooled, a cooling section each is arranged above the section and on both sides of the section and below the section, and the cooling sections can be used individually or in combination, wherein each cooling section is composed of at least one nozzle or a group of interconnected nozzles, and wherein the nozzles can be controlled individually or together.

Apparatus for the controlled cooling of hot-rolled sections, particularly beams, directly from the rolling heat

A method of cooling section steel, particularly sectional steel girders, from rolling heat, wherein, prior to a final air cooling, a water cooling process is carried out in such a way that section steel portions with material concentrations are cooled at outwardly projecting portions of the steel sections over a width of application and a duration of application which are variable and subject to a predetermined cooling strategy supported by a process computer to a value which is at least still slightly above the transformation temperature Ar1.

Method of cooling sectional girders

A runout and braking device, particularly for medium steel rolled sections, includes a run-in roller table and a braking device arranged laterally offset and parallel to the run-in roller table, wherein the run-in roller table and the braking device form a runout and braking system. The runout and braking device of the above-described type includes a braking device with a rigidly arranged braking trough with a bottom which is outwardly inclined relative to the horizontal direction. The run-in roller table includes a lifting bottom forming a plane, wherein conveying rollers mounted below the lifting bottom protrude above the plane of the lifting bottom. Pivoting devices are provided for pivoting the run-in roller table together with the lifting bottom and the conveying rollers arranged below the lifting bottom about a laterally offset pivoting point into an inclined position toward the braking trough.

Runout and braking device particularly for medium steel rolled sections

A method and an arrangement for severing and controlled cooling of individual rods from a rolled section, particularly from a section of preferably high-grade steel which emerges hot from rolling at final speed from the rolling line of a finishing train, wherein the section is divided during its passage through parting shears into cut lengths and wherein a cut length each is conveyed after severing to an annealing strip or an annealing furnace. The rolled section is supplied to parting shears whose knives rotate on both sides of the section in a horizontal plane and which, when severing the section, displace the resulting section ends in the horizontal plane laterally relative to each other by a certain distance.

Method and arrangement for severing and controlled cooling of individual

Device to separate without gaps the trailing end of a leading individual length of rolled stock and the leading end of a following length, which are parted from a rolled billet by cross-cutting shears, in the live-roller feed bed upstream of cooling beds, comprises a separate trough section disposed downstream of a switch in the form of a separating diverter subdivided into two parallel longitudinal sections, one with a fixed trough section and one vertically displaceable trough section which forms a depressed portion at a lower level. The switch and the trough section are jointly displaceable in the same direction transversely to the conveying direction in a horizontal plane by a displacement device in such a way that the leading end passes over the trough section in a curved path directed in an inclined manner towards the outer lateral wall of the fixed trough section and after the switch has been shifted the trailing end of the length is drawn in through the trough section disposed at a lower level and forming a depressed portion avoiding lashing of the trailing end of the length discharged from the switch and resultant surface damage even at high run-up speeds.
