Hot Shortness

Pain Point

Casting steel with a high amount of copper leads to the effect of hot shortness. This means that the copper in the steel bath tends to agglomerate at the surface of the strand. This leads to a high amount of quality issues, foremost the appearance of defects at the surface. 

Benefits:

The digital twin, on the one hand, with its continuously updated data describing the current state of the machine and the process, and on the other hand, with its option to simulate a variety of aspects by using expert models and solutions, can be used to optimize the cooling strategy to minimize the effect of hot shortness. This makes physical tests more and more redundant, and the risk for the production is minimized.
