  • Patent number: 5927634
    Abstract: A method of coiling steel rod arriving continuously comprises the steps of rotating about an upright axis a coiling basket defining a space centered on the axis and defined by an annular inner wall, an annular outer wall, and a floor between the walls, and feeding the rod into the space to form a coil resting on the floor and formed by a multiplicity of turns. The coil is, once formed, raised out of the space and simultaneously axially compacted and is also stabilized. More particularly the coil is stabilized by spraying an outer surface of the coil with a coolant while raising the coil out of the space. Normally the coil is rotated about the axis as the coil outer surface is being sprayed.

  • Patent number: 5902422
    Abstract: A method of coiling or placing bar steel or wire in coils, wherein the rolling stock is reeled from rolling heat in a basket or is placed by a coiler in the form of coils onto a conveyor and is collected at the end of the conveyor over a mandrel into a coil, wherein the rolling stock is cooled during coiling and the rolling stock is further cooled after the coiling process or the formation of coils. Cooling of the rolling stock from rolling heat prior to coiling into the transformation range characterized by the Ar.sub.3 line or Ar.sub.1 line of the transformation time-temperature diagram corresponding to the type of steel to be cooled is extended, such that, depending on the type of steel, the rolling stock is transformed immediately after cooling prior to, during or after coiling, uniformly over the entire length and entire cross-section thereof essentially isothermally from the austenite phase into the ferrite phase or pearlite phase and, as required, into the bainite phase.

  • Patent number: 5830293
    Abstract: A method of cooling steel sections which are hot from rolling by means of shock-like cooling following the rolling process so as to form a martensitic surface layer, and by subsequently autogenously tempering this surface layer by means of core heat to obtain a tough-resistant structure with an austenitic remaining cross-section, wherein the method is used in connection with types of steel which, with uncontrolled cooling in air, would directly transform from the austenitic phase into martensite because of their alloying elements from the group Cr, Mn, Mo, Ni and other suitable elements.

  • Patent number: 5440889
    Abstract: A method for cooling of profiled rolled material hot rolled in roll stands, especially rails on a cooling bed by natural convection or by forced air cooling, which includes conveying the rails across the cooling bed with the rail heads oriented downwards. The apparatus for effecting the method includes a cooling bed having support elements which support the rails in a suspended state with the rail heads oriented downwards.
