3-roll-cross rolling mill

Owner:

GMT mbH, 13086 Berlin
EAI Elektro- und Automatisierungstechnik GmbH Ilsenburg, 38871 Ilsenburg
Hüttner Maschinenfabrik GmbH, 06507 Rieder

Content:

Special design features of a 3-roll cross rolling mill of conventional design which permit a defined roll adjustment under load and thus enable the production of round bars with variable diameters over the bar length if required.

Thermomechanical treatment of round steel bars heated above the recrystallization temperature useful in the thermomechanical and heat treatment of steel

Owner:

GMT mbH, 13086 Berlin
ThyssenKrupp Automotive AG, 44793 Bochum

Content:

Process for thermomechanical treatment of round steel bars through the controlled formation of the microstructure to enables a targeted improvement of the property parameters in line with the load profile of the end product.

DE10315419B3
Production of screw springs or stabilizers made from steel comprises comparing the heating temperature over the rod lengths and maintaining between the rollers

Owner:

GMT mbH, 13086 Berlin
ThyssenKrupp Automotive AG, 44793 Bochum

Content:

Production of screw springs or stabilizers made from steel comprises. A predetermined torsion of the material in the edge region and a required deforming gradient are achieved over the cross-section. After exceeding the critical degree of deformation of the edge recrystallization processes take place so that post heating above Ac3 is carried out, the rods are wound to form a screw spring or bent to form a stabilizer, hardened and tempered.

DE102005014221B4
Method for ensuring uniform deformation in open die forging

Owner:

GMT mbH, 13086 Berlin

Content:

Method for ensuring uniform through-forming of heavy forgings, in which objectively present forming characteristics are optically recorded in the form of the so-called forging cross and the image data are evaluated by a process computer in such a way that the intensity and distribution of the forming can be determined therefrom and, in this basis, the design of the subsequent bite offset can be derived.

DE20302547U1
Device for online determination of surface temperature of working roller in hot-rolling mill

Owner:

GMT mbH, 13086 Berlin
EKO Stahl GmbH, 15890 Eisenhüttenstadt

Content:

Device for online determination of the surface temperature of a working roller in a hot-rolling mill comprises heat-insulating, shielded temperature sensors for measuring the temperature of the roller cooling water. The temperature sensors are integrated in the wiper girder of the working roller.

DE102008036237B3 / EP000002157194B1 / AT000000528413E
Method and assembly for inline reforming, treatment and alignment of rod-shaped metal parts

Owner:

GMT mbH, 13086 Berlin

Content:

Process and plant with all the necessary process steps from heating the starting material to forming temperature via the forming process, the quenching and tempering process, the straightening of the heat-treated steels to the machining finishing in an inline production line. Hot-rolled, scale free bars in quenched and tempered steel quality are used as starting material.

DE102017003200A1
Process for producing plated round bars

Owner:

GMT mbH, 13086 Berlin

Content:

Process for the thermomechanical treatment of steel, in which the starting material is heated to a temperature above the recrystallisation temperature, austenitised, maintained in a temperature-compensating manner and then rolled.
