Abstract: The method has the aim of obtaining Mn mini-tablets with a concentration of the metal ranging between 90 and 98%, Al particles being the binding element. The method is based on the use of ground electrolytic Mn from shales with a chemical purity of 99.7% or higher. The product is screened with a mesh of less than 450 micra, wherein the fine powder content should be less than 15%. Moreover, atomized powder Al obtained by mechanical processes with a granulometry of between 100 and 800 micra and with over 80% of the powder being between 350 and 720 micra should be used in the method. The method is carried out in a device having a storage hopper (1), a diffuser (4) of the product in the hopper (1), a hopper for compacting and shaping the mini-tablets in molds (9) in combination with pressing punches (7 and 8) and with the aid of an alveolar and dosing valve (10) mounted between the feed chamber (5) and the compacting chamber (6).

Abstract: The ferrules and feeding head and supply elements, insulating or exothermic, are obtained by blowing or manual molding from a formulation which comprises aluminium silicate hollow micro beads, with an alumina content below 38% in weight, an agglomerant and optional loads, in non fibrous form. Depending on the density of the micro beads, appropriate formulations may be obtained for the manufacture of ferrules and insulating and exothermic feeding head and supply elements. the ferrules obtained, have an external and internal dimensional exactness and may be coupled to the mold after production, without additional handklings and in a manual or automatic manner. Said ferrules are of interest in the production of metallic ferreous or non ferreous parts.

Abstract: Briquettes or tablets to be added to an aluminium melt, are made up by the combination of an agglutinated powder which include, at least, an aluminium powder, a powder of one or more metals or alloys including those to be added, and a wax-type organic compound, all in adequate proportions. This combination allows the increase of the dissolution velocity of the added metals, the recoveries of the added metal, a better stirring of the melting aluminium, and the reduction of impurities and of accumulated metal in the bottom of the furnace.
