![]() ![]() The core blowing and curing steps for the PU coldbox process were analyzed, making it possible to draw preliminary conclusions regarding the existing defects.įigure 3. This core, called the thin waist core, represents some of the biggest challenges for Usiminas core production: its length (920 mm), substantial changes in the sand flow direction during blowing, the need to fill certain parts of the core through counter-flow and big variations in the cross section within the core.įirst trials showed problems with the process, which led to a complete collapse of the lower part of the core. The main goal was to optimize the process conditions for the existing tooling layout. The first project on which this software was utilized was already in progress at that time. The bottom of the core collapsed due to a lack of strength.īrazilian steel giant Usiminas recently introduced the new foundry core making simulation software MAGMASOFT® as part of their strategy to establish robust designs and processes for their core production line.
