78. HärtereiKongress + Steel Innovation 2022

Trade fair

Place Köln
Location Koelnmesse GmbH
Time all day

Parallel to the AWT Hardening Congress (HK), the new Steel Innovation Conference (SI) of AWT and DGM will be held for the first time in 2022.

Thus, for the first time, two symposia and a trade fair will be held under one roof. Meet the GMH speakers at both trade fairs.

Lecture SI 2022 – Inka Meyer (Process assurance & process technology GMH)

Lecture title: Improving the homogeneity of case-hardened steels by using advanced continuous casting technologies.

A uniform distribution of alloying elements and a resulting homogeneous microstructure in steel is essential for processing and component properties. Segregation, which occurs for physical reasons during solidification, cannot be completely avoided in large-scale production, but can be significantly reduced by modern technologies in continuous casting, such as Mechanical Soft Reduction (MSR). The application of MSR to case-hardened steels offers the potential to improve the processing and distortion properties of gear components and thus optimize yield and component properties.

The results obtained show, using different case-hardening steels as examples, that significant homogenization of the solidification structure, distribution of alloying elements and a resulting uniformity of microstructure and hardness can be achieved on the rolled bar steel. In addition to the usual methods, new methods were also used for the investigations. Initial results from industrial series production indicate that the tendency to distortion of components made from case-hardened steels treated with MSR is significantly reduced.
