Abstract. This work deals with the impedimetric monitoring of used-sand regeneration in foundry industry. During used sand, a quartz sand similar to new is produced from already molding and core which especially serves produce cores. We explore whether progress can be assessed situ based on measured impedance spectra their features. The impedances plate capacitors filled different typical mixtu...

Abstract This paper proposes a methodological framework to develop data-driven process control using pure industrial production data from cast iron foundry, despite the limitation of complete casting traceability. The aim is help sand foundries produce good castings. A reference which produces mainly automotive and oven parts with automatic molding pouring machines, was selected. Past data, whe...

An increased lung cancer risk has been described among foundry workers. Polycyclic aromatic hydrocarbons (PAHs) and silica are possible aetiological factors. This study describes a urinary PAH metabolite, 1-hydroxypyrene (hpU), as well as the degree of cytochrome P450IA2 activity/induction as reflected by the urinary caffeine ratio (IA2) in 45 foundry workers and 52 controls; IA2 was defined as...

Abstract The last two decades have seen a growing trend toward the use of inorganic binders in core making for metalcasting field. Despite health and environmental benefits binders, wider commercial requires ongoing technical improvements to address some potential inherent limitations this technology. Considering that cores can suffer from storage stability, study sets out check whether are fit...

Abstract The aims of this study were to determine Cu(II) metal ion adsorption ability by using andisol soil and foundry sand as an adsorbent. Andisol activated with 3 M NaOH. Adsorption copper (II) performed on the composition 100:0, 75:25, 50:50, 25:75, 0:100 (wt%), pH solution variation 3-7, contact time 15-135 minutes batch system. final concentration at equilibrium was measured Atomic Absor...
