The purpose of this study was to evaluate the production feasibility of triaxial whiteware using sand from cast iron moulds as a raw material instead of silica, and recycled glass in place of feldspar. Formulations were prepared using sand, glass waste, and white-firing clay such that only 50% of the composition was virgin material (clay). The ceramic bodies were formed by pressing and fired at...

OBJECTIVES To assess the acute and chronic ophthalmological effects of triethylamine exposure among foundry workers. METHODS Ocular effects on people currently, previously, and never exposed to triethylamine in a foundry cold box were studied at two points in time. The initial phase included an ocular examination with a slit lamp to assess corneal health, a visual acuity test, and a questionn...

In many foundries, numerical simulation is used to determine the origins of different defects as this tool allows acceleration design process. However, databases provided by software do not seem tally with actual properties material. fact, every foundry uses a grade steel and varying mixtures sand. An evaluation impact material showed importance measuring physical property improve database soft...

BACKGROUND Foundry work is associated with serious occupational hazards. Although several studies have investigated the health risks associated with foundry work, the results of these studies have been inconsistent with the exception of an increased lung cancer risk. The current study evaluated the mortality of Korean foundry workers due to malignant and non-malignant diseases. METHODS This s...

Methanol synthesis catalyst (MSC) waste was applied as the principal component (till 70 wt.%) of sustainable ceramics in composites with bauxite processing (RM), and foundry sand (FS). The results initial components' chemical interaction studies by a complex methods (XRD, SEM/EDS/mapping, AAS LAMMA) during heating demonstrated amorphous glasslike new formation, their filling pores compaction ce...

The three-dimensional sand mold printing technology (3DSP) for casting molds via a binding jet is breakthrough in the mold-making process. It favorable combination of digital forming and casting, which significantly interesting research area foundry industry. This study has proposed an edge extraction approach region bed image. With information, measures accuracy printed molds, offers basis ass...

Loss-on-ignition (LOI) is an important thermo-chemical property test for many foundry materials. Applications include new sands, green sand systems, chemically bonded cores and molds, sand additives, and reclaimed sands. LOI has been an important quality control measure carried out off-line. The AFS-defined LOI test uses a muffle furnace that is time consuming, often requiring three hours; a mo...
