High Efficient Solution for Hot-Rolled Blanks in Laser Quality

Kreuztal, Deutschland (PressExposure) March 02, 2012 -- The processing of blanks in laser quality with plasticity degrees of up to 80% inside the material to be leveled and a high relief of stresses for further processes represented the challenges to be mastered by Heinrich Georg GmbH Maschinenfabrik for Tata Steel Service Centre UK. Together with its daughter company Heinrich Georg UK Ltd GEORG finishing lines developed a new high performance leveler for hot-rolled steel blanks with an extremely rigid machine frame for the required high plasticity degrees. The maximum bending of the entire machine frame under highest load is 0,2mm. Thus GEORG ensures optimum leveling values in laser-quality for a sustainable blank production.

"Unfortunately we run into problems with our previous leveler. Due to the still remaining residual stresses the blanks could not be used for the subsequent laser-welding process. Deliveries were rejected by our customers. With the new leveler made by GEORG we could overcome such problems and increase the quality considerably" explains Mark Davenport, General Manager Tata Steel Service Centre UK.

Integrated problem solver for the cut-to-length line

Thanks to the intelligent GEORG technology steel strips with thicknesses between 3 - 6 mm and tensile strengths of up to 600 N/mm² and strip widths of 1.000 - 2.000 mm can be cut precisely. A leveling grade of laser quality has been achieved. That means the blanks are almost free from stresses.

"Our engineers succeeded to meet our customer's demand 100% by using latest finite element methods (FEM). The frame construction was optimized in detail and the entire line itself was designed in a way to cope with future demands too" explains Antonio Garcia, managing director GEORG finishing lines.

After completion an experienced service team of GEORG UK took over the replacement job and integrated the new leveler into the existing cut-to-length line. "Due to the existing and limiting space condition this represented another challenge which our specialists mastered within the given time frame. After only 2 training days the first sellable blanks could be produced" explains Antonio Garcia.

In order to reach maximum flexibility the leveler was built in the proven GEORG cassette-type design with semi-automatic exchange as per customer's requirements. With the overall technical view for the best result this new investment will ensure the production success at Tata Steel Service Center UK.
