In order to increase the resistance of aluminium alloys a complex heat treatment is usually performed. Therefore, we must consider the reaction time between aluminium alloys and furnace atmosphera. These atmospheres ...

Nitriding at low temperatures, 450-500oC of austenic stainless steels lead to the obtaining of the tough layers over 1000 HV005 but having thicknesses of tenths of microns. Moreover, nitriding at 500ºC has determined the ...

Hereby paper work aims to identify and analyze the structural constituents from the steel making shop slag. Therefore, slag specimens sampled from different stages of steel making-continuous casting flow sheet in Mittal ...

The paper presents the crystalline structure, morphology, optical transmittance, electrical properties and room temperature photoreduction-ozone oxidation properties of some Al-doped ZnO thin films prepared by sol-gel ...

Each system (stand – driving) and the continuous rolling line to which it belongs have its own functional and energetically parameters. To reduce any faults of the strip surface it is also necessary to check (eventually ...

We have analyzed the fabrication technology of the link chain cable made of grade U1 and U2 steel from TREFO S.A. Galati and we had in view during the experiments several rolling programs. The main characteristics of a ...

The paper presents the evolution of the heat exchange coefficient along the path of the continuous casting unit, as a function of the cooling water flow rate and the path length. The optimization of this thermodynamic ...

Among the new method of studying the properties of the substance and the influence over the most various physical and chemical processes, used in different industrial domains, the main place is occupied by the usage of ...

For melting cast iron, carbon steel, copper and copper alloys the quartzite is still one of the most used lining material and the most cost effective as well. The silica lining has to be replaced frequently due to the ...

In most environmental pollution problems, the pollutant is released to the environment by the, almost always, turbulent flow of a carrier fluid. The pollutant mixes with the surrounding fluid (air or water) and undergoes ...
