Physical properties of low-temperature casting moulds
Journal Title: Metallurgical and Mining Industry - Year 2017, Vol 9, Issue 5
Abstract
With this paper we pursued the objectives to define the rational value for the moisture in the moulding compound applied for manufacturing low-temperature moulds (hereinafter referred as LTM), to determine the impact of moulding compound density on the mould strength properties, and to define vacuuming impact on LTM hardness while its freezing. All these have been successfully achieved with this research. In order to evaluate the research results, we applied the standard methods for defining the compound fluidity, compound density and vacuuming effect on hardness. In the course of the research, we revealed the dependences, which had not been reported before. These dependences show how the moulding compound manufacturing parameters and the process parameters impact the principal manufacturing properties of low-temperature moulds. This allows us to forecast low-temperature moulds properties or to obtain them with the desired properties and also to ensure manufacturing high-quality castings of aluminum and iron-carbon alloys.
