Research and Development
Salzgitter Mannesmann Forschung GmbH
(SZMF) is the central research company of the Steel and Tubes
divisions. The R&D activities are concentrated on materials development and processing, as well as
application, coating and testing technologies. In addition to the Salzgitter Group companies, customers
include external companies, for example from the steel processing industry, the automotive industry,
machinery and plant engineering, energy technology, as well as the construction industry.
SZMF's R&D expenses in 2013 are likely to remain at the year-earlier level.
New high vacuum melting and casting system
One of the fundamental challenges in steel research consists in identifying new alloy variants and in
advancing them from laboratory scale to industrial production. The vacuum induction melting and
casting system that was installed at the end of 2012 considerably enhances efficiency, thus significantly
accelerating the development of innovative high alloy steels at SZMF such as HSDŽ steel. As a result, up
to five different alloys each with a melting weight of two kilograms can now be produced in one single
Wavelet filtered eddy current array test for optimized product quality
At SZMF the mathematically extremely sophisticated wavelet filtering has been qualified for daily
operations for the first time. It enables test signals that occur in ultrasonic testing of rolled steel
products, for example, to be more effectively digitally processed than with conventional filtering
procedures. A favored area of application is signal denoising. A short while ago a process for denoising
eddy current array test signals was developed for the Salzgitter Mannesmann Precision Group (SMP
Group) to achieve another improvement in error detection and reduce pseudo-error display for this type
of testing as well.
Sustainable bottling of still water under ultra clean conditions
KHS GmbH (KHSDE) has developed a machine for filling PET bottles with water under ultra clean
conditions. This filling machine significantly reduces air consumption and the use of cleaning agents.
Additional advantages of the Innofill PET NV filling system for the customer include the closed, hygienic
design, space savings, cost-effective maintenance and the associated cost savings. The new product is
especially intended for blocking with a stretch blow machine. It is suitable for a wide range of bottle
sizes up to three liters and achieves a maximum performance of 72,000 receptacles an hour. Innofill PET
NV's non-contact filling of plastic bottles by means of a free-flow filling valve represents the highest
microbiological and hygienic safety. Thanks to impeller flow metering demineralized water can also be
