This paper presents results of the research of micronization grinding of dry mica in a planetary ball mill. Investigation was conducted in order to improve the quality and to obtain clearly defined properties and characteristics ...
Failure of steam line causes determined by NDT testing in power and heating plants
(Gruppo Italiano Frattura, 2013)
This paper examines leakage and damages of steam and provides an overview of NDT testing in order to determine the cause of steam lines failure in power plants and heating plants. This approach may be applied to similar ...
Optimization of the production process through response surface method: Bricks made of loess
(Elsevier Sci Ltd, Oxford, 2013)
Loess clays are commonly used to produce bricks. Heavy clays, taken at location near Zrenjanin, Serbia, are used as a representative raw material in this study. The sample, containing about 28% of clay sized particles, is ...
Influence of modifying methods on quality of eutectic and hypereutectic silumine for diesel engine pistons
(Maney Publishing, Leeds, 2013)
The results of the investigation of the influence of different modifiers (sodium, phosphorus, antimony and strontium) on the quality of AlSi12CuMgNi and AlSi18CuMgNi alloys, which are used for the production of pistons, ...
Application of chromite in the production of refractory coatings
(Verlag Schmidt GmbH, 2013)
This work investigated the possibility of developing new chromite-based refractory coatings for hot metal casting applications. The coating composition and rheological properties were optimized by careful choice of binding ...
