| 20110197670 | METHOD AND APPARATUS FOR MEASURING METAL PORTION IN DROSS - Method and apparatus for determination of portion of pure metal in dross from a dross source, whereby the metal portion in the dross is determined by measuring the dross density and calculating the metal portion in accordance with the formula m%=k−ρ+a, where m% is percentage pure metal, ρ is the dross density and k and a are empirical constants. In accordance with the invention, the apparatus comprises a closed container ( | 08-18-2011 |
| 20110007600 | DEVICE FOR ADDING FLUID TO A LIQUID - Device for adding a fluid to a liquid, for example of gas and/or particles to liquid metal. A rotor is rotated immersed in the liquid, comprising a hollow rotational body | 01-13-2011 |
| 20110006052 | METHOD AND DEVICE FOR HEATING A FLUID - Method for heating a fluid, in particular a fluid which is not electrical conductive, where a rotor body ( | 01-13-2011 |
| 20100206128 | METHOD AND DEVICE FOR REMOVAL OF ELEMENTS RESOLVED IN A METAL MELT - Method for removal of elements from a metal melt in a container, which melt contains a base metal and elements of undesirable constituents, in which the metal melt is heated to a level maintaining the content melted. The metal melt is heated to a level causing vaporization of an element to be removed, but under the level providing gas pressure for the base metal. The container with the metal melt is brought under a reduced pressure in at least one compartment in which the temperature is maintained under the vaporization level of the element to be removed. A device for the removal of elements from metal melts, with a container ( | 08-19-2010 |
