Cold Drawn Steel - Cold Drawing

Cold Drawn Steel – Cold Drawing

The process of cold drawing is a procedure by which steel profiles are formed in order to achieve complex cross sections of excellent precision in these cold drawn steel shapes. After careful pre-treatment and de-scaling, the special profile bars are drawn through a forming die. This operation can be repeated up to three or four times.

Cold drawing of hot rolled and hot extruded special pre-shape steel profiles tightens the cross-sectional tolerances, thus leading to significant improvement in dimensional accuracy and surface quality. Cold drawn steel special profiles offer the same precision achieved by machining but without the waste.

Cold drawn special profiles offer extensive advantages, among other things:

  • Smooth and scale-free surface
  • Sharp edges
  • Uninterrupted grain orientation
  • Increased tensile strength and yield point

Applications include many cold drawn steel shapes such as both carbon and stainless steel fittings, various stainless steel shapes used in aerospace applications, linear motion and machinery applications.
The economical advantages of using cold drawn stainless steel profiles are so numerous that in most cases stainless steel profiles offer the best solution to custom engineered designs.


Hot Rolled Steel - Hot Rolling

Hot Rolled Steel Shapes – Hot Rolling

  • Hot Rolled Steel Shapes

During the production of special hot rolled steel profiles by hot rolling the input billet or slab is formed into lengths up to 70 m using two oppositely rotating cylindrical rolls. The hot rolled steel shapes of this forming technique are used in a multitude of industrial applications. Hot rolled special profiles offer innovative solutions whether it be for automotive, materials handling, railroad or thicker flange and web thickness structural steel shapes use. Finished hot rolled steel shapes are roller straightened and sheared into production lengths or sawn into fixed lengths according to customer wishes.

  • Targeted strengthening of highly stressed areas of component parts
  • Best mechanical properties through uninterrupted grain orientation
  • Best shape properties and fitting accuracy by maintenance of the tightest tolerances


Hot Extruding - Extruded Steel Shapes - Steel Extrusions

Hot extruding – Extruded Steel Shapes – Steel Extrusions

  • Extruded Stainless Steel
  • Stainless Steel Extrusions

During hot extrusion a round steel billet is pre-heated and, after leaving the furnace, is pushed through a forming die into a profile bar using a ram with an extrusion force of 2,200 ton. Hot extrusion offers substantial advantages in comparison to hot rolling forging or machining.
Hot extrusion can be used to make complex profile shapes even using metals which are difficult to form. In addition, small lot sizes can be produced economically.
Hot extruded profiles offer the benefit of:

  • Different material thicknesses within one profile cross-section
  • The possibility to use in highly sensitive areas, where the special profiles must withstand specific demands of temperature, pressure, aggressive media or hygienic requirements
  • Seamless structure of solid and hollow section

Cold Rolling - Cold Forming - Rool Forming

Cold Rolling – Cold Forming – Roll Forming Steel Shapes

  • Cold Rolling steel shapes
  • Cold Rolled steel shapes
  • Cold Formed steel shapes
  • Cold Forming steel shapes
  • Roll Forming steel shapes

Roll forming can be described as a continuous bending operation done at room temperature in which sheet or strip metal is plastically deformed along a linear axis. Tandem sets of rolls (known as roll stations) shape the metal stock in a series of progressive stages until the desired cross-sectional configuration is obtained by cold rolling.
Roll forming is ideal for producing parts with long lengths or in large quantities. It can also produce multiple length parts from the same set of tooling. Virtually any material that can be cold formed by sheet forming techniques can be roll formed.
The process is quite cost effective for large production runs, although sometimes roll-forming is utilized regardless of quantity, when dimensional consistency is of tantamount importance.

ROLL FORMING PROCESS
Roll forming is a metal fabrication process that utilizes sheet metal in coil form where the material is progressively shaped as it passes through a series of roller dies for cold rolling. During this process of producing a profile it is possible to pierce holes, slots, or notches in a component.  The process is continuous and very labor efficient. Virtually all materials can be roll formed.  Roll forming is a bending operation that is performed at room temperature.


Specially Engineered Milled

Specially Engineered Milled (SE-|M|®) Technology

Specially Engineered Milled (SE-|M|®)process for Tight Tolerance and Optimum Hardness for customers whose products require profiles with:

  • 0.2 mm tolerance in the key functional area
  • Harder surface as a result of removal of the decarburised surface layer
  • Cost savings resulting from increased wear resistance

The demands placed on industrial trucks are continuously increasing: they must be faster, higher and more efficient even when subjected to heavy loads. To put it briefly: mast profiles are subjected to extreme loads during use. For a long time, the profile manufacturers were barely able to keep up with the breathtaking pace at which the materials handling industry was developing. Mast profiles, which had remained almost unchanged for decades, forced the industrial truck manufacturers to develop a collection of complex measures to compensate for increased mast lift heights and load pressures. For this reason Hoesch Schwerter Profile GmbH, starting in 2003, carried out research to determine how mast profiles could be designed to achieve greater wear resistance and improved suitability for greater mast lift heights. The result of the years of research: combining the conventional hot rolling process using a suitable material with an efficient machining process makes it possible to meet the highest demands. The ”specially engineered milled process” was patented in 2008.
