  • CORUNDUM FORMATION

    Corundum formation and its subsequent destruction of the furnace lining can be a constant worry to the maintenance department. The picture below is all too common of a reality in a typical Aluminium Foundry. The following conditions facilitate corundum formation: • Excessive free silica in the ref ...

  • ALUMINIUM, Key in the construction of modern aircraft.

    A combination of lightness, ressitance and high electrical and thermal conductivity, is the property that became a key to Aluminium and its alloys, for the construction of aircraft,  automobiles, or engines, among many other applications. And it is that a given volume of aluminium weighs less t ...

  • CUPOLA FURNACES

    The dictionary defines a cupola as a domed roof, a gun turret or a vertical cylindrical Furnace to melt metal to further refine it in other furnaces, or to cast it into useful shapes. The editors of Encyclopedia Britannica claim that René-Antoine Ferchault de Réaumur built the first cupola furnace ...

  • TILTING ROTARY FURNACES

    Due to the considerable savings produced during recycling and to the simplicity of the process, the aluminum started to be recycled a long time ago, and today is a widespread activity, technically solved and profitable, In fact, more than the 75% of the last 100 years produced aluminum is today in u ...

  • How we can optimize the performance of cupola furnace?

    Methods of improving the behavior of cupola: Keep Furnace in optimum regime of operation.Relationship between inyection velocity coke charging & melting velocity (see Junblüth diagram) Avoid excessive temperatures in the casting and reduce overheating. Ensure uniform load: The distribution of m ...

  • SEA WATER MAGNESIA

    During the period between 1915-1941 many attempts were made to develop new production process of magnesium, especially in Europe. By the urgent need for magnesium created by the threat of the second world war, some of those procedures were employed on a large scale in England, Canada,  United State ...

  • MEDIEVAL IRON FURNACE in GALDAKAO (Spain)

    In 2013, a reduction of iron furnace was located in Galdakao (Bizkaia-Spain). This building,is the largest in Europe, with 5.5 meters tall and 4 wide, this large furnace that was based on the manual work against others later which were helped from the force of the water was really great. Before the ...

  • ITACOLUMITAS

    Itacolumitas are special sandstones which reach this unexpected flexibility due to special interlocking of its grains, coming from its geological growth. Name comes from the Brazilian country of Itacolumia, Minas Gerais, where it was firstly identified.  This strange elastic behavior developed by n ...

  • ALUMINIUM, young metal

    Aluminium is a relatively young metal in that two hundred years ago no one knew that it existed. It was not until 1825 that Hans Christian Oersted, professer of phisics at the University of Copenhagen managed to produce the first few milligrams of pure aluminium in his laboratory. It took a further ...

  • NEWTON & CASTABLES

    If we speak about Sir Isaac Newton, all we go back to our school days and see how relevant is F=m·a, second motion law in our lives. All we will agree but, if I say any refractory castable, any civil concrete or, in general, any fluid mix would be properly managed through pumping, casting, conveyin ...

  • WHAT IS PLASMA?

     Without going any further, the Sun is, in itself, a gigantic plasma, full of atoms of Hydrogen and Helium that have lost totally or partially their electrons as a result of the extremely High temperaturas generated inside (they estimate that the temperatura of the Sun is approximately 6000ºC in s ...
