HR
Projekt HQCastScrap jača kapacitete ljevaonica u zemljama obuhvaćenima RIS-om (Regional Innovation Scheme) i usmjeren je na smanjenje materijalnih troškova proizvodnje odljevaka te emisija CO2. Vlastiti povratni materijal niske kvalitete u metalnom ulošku snižava svojstva odljevaka, dok njegova otprema na recikliranje povećava troškove i uzrokuje gubitke kritičnih legirnih elemenata. Recikliranjem vlastitog povratnog materijala u samom pogonu ti se gubici izbjegavaju, čime se povećava učinak inovacija – primjenom troškovno učinkovitih strategija kružnoga gospodarstva usmjerenih na proizvod, utemeljenih na integraciji trokuta znanja (KTI, Knowledge Triangle Integration), što je u aktualnoj krizi materijala i energije od presudne važnosti.

Foundries of ferrous and non-ferrous alloys produce significant amounts of the return scrap from gating and feeding systems, from rejected castings and tooling products. This material is either added to the clean metallic charge or transported to plants specialising in recycling and cleaning of the scrap. In the first case, the scrap addition decreases the liquid metal quality due to an increase of dissolved gases and non-metallic inclusions. In the second case, different types of scrap are mixed within the same group of castings, e.g. Al-Si, Al-Cu, Al-Zn, Al-Mn alloys, with various contents of several expensive alloying additions, which causes the necessity of controlling and supplementing the chemical composition, without which the castings produced of this material would be of a decreased quality. Transport costs are also growing. Optimising the processes of alloys melting, moulds pouring and controlling the cooling processes in casting moulds as well as designing the optimal casting and feeding systems are directed towards lowering production costs of the casting at simultaneous improvements of its mechanical and functional properties. The final effect constitutes the material savings and reducing CO2 emission which are related to the economy of the energy consumption by charge remelting processes and to the improvement of the environment protection. The solution is on-site processing of the foundries own scrap with the proper selection of the return foundry scrap.
