As part of the casting process, foundries create sand molds and cores to hold the molten metal to specific dimensional tolerances. Although most of the waste foundry sands (WFSs) from this process are land filled, there is great interest in diverting them for use in agricultural and geotechnical applications. One potential limitation to their beneficial use is concern that the WFSs will leach h...

On the way to building smart factories as vision of Industry 4.0, casting process stands out a specific manufacturing due its diversity and complexity. One segments foundry design is application artificial intelligence in improvement process. This paper presents an overview conducted research studies, which deal with In review, 37 studies were analyzed over last 15 years, clear indication type ...

Rough logic and rough sets theory are mainly devoted to analysis of incomplete, uncertain, and inconsistent data. An exploited in the article result of the theory is the so-called rough information system that gives a model for dealing with the situation in which some real objects are represented ambiguously via defined approximation (alternatives of values of the objects attributes). The propo...

The increasing demand and exorbitant use of river bed sand in foundries over the years have led to its depletion at an alarming rate. Consequently, many states India imposed severe restrictions on mining riverbed sand. Therefore, effort is made explore potential sea for cast iron foundry applications. Experiments were performed optimizing composition molding with respect functional properties n...

Caterpillar has been collaborating with suppliers to analyze steel castings for the tendency to form hot tears using a newly developed damage-based model. The implementation and application of the damage-based hot tear model is presented. The implementation is through an uncoupled simulation of the solidification and deformation problems using commercial software with a user-defined constitutiv...

There is a trend in the automotive producers to require that foundries use more secondary aluminum alloy ingots reduce CO2 footprint of car production. The merits this have been investigated study. Results shown requiring while simultaneously reducing elongation requirement die castings counterproductive, i.e., increases over its useful life by not taking advantage weight reduction possible. It...

Inductively coupled plasma-optical emission spectroscopy (ICP-OES) was used to determine the bulk metal elemental composition of 62 modern bronze sculptures cast in Paris in the first half of the twentieth century from the collections of The Art Institute of Chicago and the Philadelphia Museum of Art. As a result, a comprehensive survey of the alloy composition of the sculptures of many promine...

Gas permeability of moulds and cores is an important factor to consider in the casting process. In foundries, gas measured by using instruments which give dimensionless numbers. This approach enables comparison values between samples often not quantified units. this study, a custom-made measurement system introduced that applies Darcy’s law, where pressure gradients for different flow rates are...
