Advanced Materials Research, 2015
Systematic change of riser size together with variation of thickness and length of A201 aluminum alloy plate castings were studied to investigate the correlation between mechanical properties and porosity content. The molds with end chill for plate castings were made of 100% chromite sand by CO2 process.

This paper presents a critical analysis of molding technology a steel castings (340-550W steel grade), of the Toothed framework type. This casting is used to manufacture an reducer on 125kW (is a subset of the reducer). In the industrial practice, for the casting by Toothed framework type, cast of steel is used a molding mixture based on chromite-sand,

The Mirdita ophiolite is located in the northern ophiolite belt of Albania. Based on differences in the internal stratigraphy and chemical composition of the crustal units, two types of ophiolites have been recognized in the Mirdita ophiolite, namely the Western Mirdita Ophiolite (WMO) and the Eastern Mirdita Ophiolite (EMO) (Dilek et al., 2008 ...

Textural and mineralogical characters of ore together with technical parameters of enrichment plants strongly affect efficiency of chromite sand concentration with shaking tables. Such parameters were studied at Brieville gravity enrichment plant that works chromite ore from different mines within Andriamena district (Madagascar).

Chromite foundry sands form the mold in which molten metal is contained until it solidifies in the desired shape. Chromite is used because of its resistance when exposed to heat and is chosen over typical silica sand when a higher casting temperature is required.
