The New Salzgitter Mannesmann Forschung Technology Center Continuous R&D Process Chain - Systematic Product Development

Abstract

Since the commissioning of the new technology center in November 2007, the research facility at the Salzgitter site has been equipped to simulate the entire process chain, ranging from the manufacture to processing of steel on the lab scale. A cold‐rolled hot‐dip galvanized dual‐phase steel of grade HCT780XD is used to illustrate in detail the function (manufacture, optimization and processing) of the new technology center. This includes (i) a special laboratory rolling mill for cold rolling and skin passing samples under strip tension; (ii) an annealing simulator; (iii) a hot‐dip galvanizing simulator and (iv) a high‐speed‐tryout forming press.

Comparison of Numerical Simulation and Experiment for the Microstructure Development of a Cold-Rolled Multiphase Steel during Annealing

“…Sheets of 450 mm x 120 mm were annealed using the annealing simulator [4]. After annealing, tensile tests in longitudinal direction with standard A80 samples were conducted according to DIN EN ISO 6892-1.…”
