A method of cooling on a cooling bed hot-rolled steel sections from rolling heat, wherein the sections, particularly rails, have section parts of different masses arranged at a distance from each other over the cross-section of the section, and an apparatus for carrying out the method. Initially, the heat quantities to be proportionally removed from the different section parts in dependence on their mass and temperature and the quantity of cooling medium required for this removal are determined and computed by using measuring equipment together with a computing unit by means of a computer program. Subsequently, cooling of the different section parts or their masses is carried out in a controlled manner in such a way that the section parts reach with as little time delay as possible the transformation line A /A during the decomposition of the gamma-mixed crystal into ferrite and/or pearlite while releasing the transformation heat.

Method and apparatus for cooling hot-rolled sections

A method of heat treatment of wire including cooling the wire stock immediately after the stock leaves the rolling heat region to a temperature below the starting temperature of martensite formation and, thereafter, forming wire coils.

Method of heat treatment of wire

A water cooling device for a controlled cooling of wire, small sections, and ribbed concrete wire guided along a wire rod guiding line out of the rolling heat has a support frame that is parallel-slidable or rotatable. Parallel, adjacently arranged cooling water pipelines are provided each having a different inner diameter and mounted on the support frame. Each cooling water pipeline has arranged thereat water boxes. The cooling water pipelines have cooling water pipes having an inner pipe diameter matching the inner diameter of the correlated cooling water pipeline. The cooling water pipes are arranged in the water boxes. Each cooling water pipeline has guide grooves positioned between the water boxes for connecting the cooling water pipes of each cooling water pipeline with one another. The cooling water pipelines are configured such that, by parallel-sliding or rotation of the support frame in a direction perpendicular to the wire rod guiding line, each cooling water pipeline is positionable in the wire rod guiding line so that the wire rod is guidable in all of the cooling wire pipes.

Water cooling device for wire

A method and an arrangement for operating a rotating starting shear operating in a start-stop operation on rolling stock travelling at different speeds in wire mills, light-section mills, medium plate mills and billet mills, wherein the shear, whose gear system is connected through a coupling to a drive motor, is accelerated from the position of rest to approximately rolling speed and, after the cut has been carried out, is stopped again. A gear machine is arranged between the gear unit of the shear and the drive motor, wherein torsion-proof couplings are arranged between the gear unit or the shear and the gear mechanism and between the gear mechanism and the drive motor.
