Contact: USA ROB STEELE Foundry Advanced Clay Technologies (F.A.C.T.) rsteele@foundryclay.com JOE HOWDEN Eildon Refractories Ltd. joehowden@gmail.com 6 CONCLUSION From the foundry’s perspective, the cast weight reduction achieved by the project, not only made it possible for the foundry to use just one ladle and one furnace, which in turn not only solved the handling and pouring problems, but also resulted in a big energy and metal saving. When this is combined with the benefits of reduced machining and the ability to cut feeders very close to the flange, reducing arc air and grinding results in significant time reductions in the finishing process. From our perspective the new method and gating changes not only met the customers requirements but clearly demonstrated the benefits of reducing pouring time -20% super heat temperature -15 °C and ingate velocity by 25%. The proof of the technical benefits can be seen clearly in the as cast surface of the casting.
