Solutions for a better life can also involve highly specialised and highly technical applications for instance in steelmaking. In this area, Budenheim has developed a new binding agent concept which improves working conditions at steel mills and helps optimising steel quality. Innovation & Application Development Manager Stefan Barlag explains what this is all about.
Until now, the binding agent concept used in steelmaking includes some components which are hazardous to human health. Apart from boric acid, it also contains organic components like phenolic resin. They develop toxic gases and strong odours when heated during start-up. This leads to more difficult working conditions for the steelworkers, and exposes them to strong health challenges. Moreover, steel quality is also affected by these components.
But before it can be cast in endless strands, the steel must first be introduced into a distribution system which delivers steel equally to various steel strands. This tundish is a wide and open vessel with one or more holes in its bottom which allow the liquid steel melt to flow out at a temperature that exceeds 1600 degrees centigrade.
To make it resistant against these extremely high temperatures, the tundish must have a lining made of refractory materials.
