Controlling the structure of aluminium alloys before casting with the thermal analysis equipment THERMATEST* 5000 NG III

摘要

To maximise the technical benefits and cost effectiveness of grain refinement and modification, the foundry needs to ensure that the treatment agents are used at an optimum and consistent addition rate. The use of the THERMATEST 5000 NG III, which is quick and easy to use by foundry personnel gives this facility, and with quantitative outputs ensures a consistent level of casting quality. These values can be used to set the optimum addition rates for all grain refining and modification additives and thus to avoid costly scrap due to shrinkage, leakage, porosity and hot tear.
