Abstract
Large steel castings are cooling very slow, also to 6 weeks, just the same formates tensions, which often lead even to destruction. Proposed research project intends to reduce cooling time of casting in the form for 30 to 50% and with selective cooling also to reduce rest tensions. We plan to execute active cooling with two following aims: - accelerated cooling of casting thicker walls within temperature range after finished solidification and before beginning of development of thermal tensions, that is above plastic-elastic crossing, when beginns to develop tensions in casting, - active cooling from temperature range, when beginns to develop tensions in casting, till the end of cooling with the aim to even cooling in the way, that rest tensions in casting are the smaller. In this way we reach two important economic and technological aims: - we reduce time of foundry space use, we reduce time of resources and material use for 30 to 50%, - we control development of tensions in casting and we prevent danger of crack development and with that ejection.
