Consult with us today at 313-570-5712 to discuss how our steel manufacturing process for Cold Drawn Steel - Cold Drawing, Hot Rolled Steel Shapes – Hot Rolling, Hot extruding – Extruded Steel Shapes – Steel Extrusions, and Cold Rolling – Cold Forming – Roll Forming Steel Shapes can be a cost effective solution when compared to machining, welding, forging, casting, powder metal and other steel forming processes including our Specially Engineered Milled (SE-|M|®)process for Tight Tolerance and Optimum Hardness.
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:
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.
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.
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.
Cold Rolling – Cold Forming – 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 PROCESS
Specially Engineered Milled (SE-|M|®)process for Tight Tolerance and Optimum Hardness for customers whose products require profiles with:
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.
