چکیده
B. Gal, K. Granat, D. Nowak, Wroclaw University of Technology, Department of Foundry Engineering, Plastics and Automation and Automation, Wrocław, Poland The presented basic research was aimed at determining a correlation between compaction degree of moulding sand and its permittivity εr at 2,45·10 9 s-1. The measurement results make a basis for mathematical description of a multilayer technological system as is a combination of moulding sand and foundry instrumentation. Analysis of the results shows that compaction significantly influences permittivity of the sandmix containing water-glass, because permittivity value increases with increasing compaction degree.

متن کاملA New Method for the Measurement of Flowability of Green Moulding Sand Nowa Metoda Pomiaru Płynności Klasycznej Masy Formierskiej
The production of castings by green sand moulds is a very important method for the manufacture of final products for different sectors of industry. In this green sand moulding process the quality of castings depends strongly on the quality of the mould, which in turn is determined by parameters such as the type of foundry machine, the characteristics of the moulding sand and the specifications ...
متن کاملInfluence of a Reclaimed Sand Addition to Moulding Sand with Furan Resin on Its Impact on the Environment
Metalcasting involves having a molten metal poured in a hollow mould to produce metal objects. These moulds are generally made of sand and are chemically bonded, clay-bonded, or even unbounded. There are many binder systems used. Binders based on furfuryl resins constitute currently the highest fraction in the binders no-bake group. Moulding sand, after knocking out the cast, is partially recla...

The influence of compaction water content on the structure has been well known forclayey soils, but has never been studied for granular materials. In this paper the structure of a nonplastictill and the effect of compaction moisture is investigated by means of water retention curvestudy, scanning electron microscopy and mercury intrusion porosimetry tests. The results show thatwhen compacted on...
