Oil pump, apropos gear pump is used for lubrication in the automotive industry. In the process of the engine, and the oil pump, there is rotation of the shaft and without bearing sleeve there would be „spending”casing which is made of cast iron. The bearing sleeve is mounted in order to reduce wear and ensure the consiste...

Stainless steel plays an important role in all emerging technologies. Detrimental effects of inclusions in steel do not only depend on their sizes, shape, distribution, but also on their chemical composition and mechanical properties. For this reason, the control of formation of non metallic inclusions and the characterization presen...

This paper examines the impact of improving working conditions and increasing capacity with Dual track system. Three different cases were examined: Power ratio 100-650 kW, 200-550 kW and 300-350 kW. All three different cases were obtained in very similar conditions (time necessary for chemical analysis, alloying processes, slag cleaning e...

In this paper will be presented a practical example of the fuel savings in the process of hot-dip galvanizing. Reconstruction of the line is carried out during the transition of equipment from one to another location. Total power of the melting furnace it was 2.4 MW, and hot air generator for drying oven, has a power of 600 kW. With ...

Cement is a mineral hydraulic binder which is formed by sintering (heat treatment) primary minerals of cement clinker at a sintering temperature. In the cement composite only cement releases heat by reaction with water, and image about the amount of heat or about temperature of solid concrete is obtained by determination of the heat of hydration of...

In this paper the effect of two different fly ash types on the properties of self-compacting concrete in fresh state and hardened state was investigated: fly ash from Thermal power plant “Kakanj” and fly ash from Thermal power plant “Tuzla”. The results of testing fresh self-compacting concrete properties show that addition ...
