Effect of Chromite-Silica Sands Characteristics on Performance of Ladle Filler Sands for Continuous Casting

Journal of Iron and Steel Research International, 2012
Free opening rate is mainly determined by the performance of the ladle filler sand. High free opening rates of ladles are required in steel making to improve steel quality. Chromite ladle filler sands are one of the most widely used ladle filler sand. Several operative variables and materials characteristics affect the performance of the sands.

Dissolution behavior of chromite mineral impurities in raw materials of glass production using scanning electron microscopy-energy dispersive spectrometer, X-ray fluorescence spectroscopy and Raman spectroscopy methods

Spectroscopy Letters
Silica sand is an essential raw material for glass production. The specification of silica sand for each type of glass is the most important point, such as chemical purity, grain size, grain shape, and their impurities. Some of the impurities in the sand

Study of the Impact of External Influences on the Protective Coating Applied to Moulding Sand

Coatings
Obtaining a good casting surface without defects requires proper preparation of the mould for the given metal alloy. It is important to select the appropriate moulding sand, which consists of a grain matrix and a binder.

Effect of Matrix Type on Properties of Moulding Sand with Barley Malt

Archives of Foundry Engineering
The aim of the following work was to determine the possibility of using barley malt as a binder in moulding sands technology. The moulding sands prepared on the basis of three kinds of sands, i.e. quartz, olivine and chromite sands were analyzed.

Application of an innovative beneficiation technique to Krasta chromite ore (Albania) for the production of high grade – low silica chromite sand

2012
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 ...
