Foundries for the metal-casting industry plays a vital role to generate byproducts such as used foundry sand. Metal foundries use large amounts of the metal casting process. Foundries successfully recycle and reuse the sand many times in a foundry but by using repeated usage of Used foundry-sand vary due to the type of equipment used for foundry processing, the types of additives, the number of...
Computer solutions Multiphysics 3.5a software was used for simulating the two-dimensional copper migration including sorption process through the saturated zone of the soil in the presence of permeable reactive barrier for equilibrium condition. The 1:3 mixture of waste foundry sand and Kerbala’s sand was used as filling material for this barrier. The waste foundry sand was represented the reac...

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 technolo...
This paper presents a case study based on a LCA (Life Cycle Assessment) research program of the silicon foundry sand (SFS) due to the large quantity of produced waste foundry sand (WFS). The foundry waste is a high priority sector within the growing European foundry industry. It is necessary to understand the full life cycle of the foundry waste in order to correctly identify magnitude and type...
this study deals with employing foundry sand (fs) as new low cost iron source in heterogeneousphoto-fenton process for the degradation of herbicide isoproturon (ipu) in aqueous solution. thecharacterization of the fs by eds confirmed presence of iron (23%) required for photo-fenton andsimultaneously confirmed absence of any heavy metals which may be susceptible to leaching. the photo-fenton eff...
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 high cost of landfilling and the potential uses of waste foundry sands have prompted research into their beneficial reuse. Roadways have a high potential for large volume usage of the foundry sands. A laboratory testing program was conducted on soil-foundry sand mixtures amended with cement and lime to assess their applicability as highway subbase materials. The mixtures were compacted in t...
K. Kaczmarska, B. Grabowska, D. Drożyński, AGH University of Science and Technology, Faculty of Foundry Engineering, Krakow, Poland The results of preliminary tests of selected properties of the moulding sands with the binder in the form of a 5 % water solution of the sodium salt of carboxymethyl starch (with a degree of substitution (DS) of 0,2 and 0,87) are presented in this study. The mouldi...
