  • Publication number: 20240124948
    Abstract: A method of reduction of a metal oxide material and a metal material production configuration adapted for manufacture of reduced metal material, a metal oxide material production unit produces a metal oxide material holding thermal energy, a direct reduction facility is configured for introduction of a reducing agent adapted to react with the metal oxide material. The method includes the steps of; charging the metal oxide material, holding thermal energy; introducing the reducing agent; reducing the metal oxide material to reduced metal material by utilizing the thermal energy of the metal oxide material to heat or further heat the introduced reducing agent for achieving a chemical reaction; and discharging the reduced metal material from the direct reduction facility. A direct reduction facility and a data program configured to execute an automatic or semi-automatic manufacture of reduced metal material ready to be transported to a metal production site.

  • Patent number: 9546661
    Abstract: The invention concerns a rotor machine and an impeller, of which the rotor machine is intended to function as a liquid pump or as an agitator in a fluid such as a liquid or a colloid, whereby the rotor machine has a pump casing (1) with an impeller (2) mounted in bearings in a manner that allows rotation around an axis (X), and in which the rotor machine has three principal flow pathways, comprising: —an axial inlet opening (4) with a defined area of opening (Ain) —a radially oriented outlet opening (5) with a defined area of opening (Aut), and —a series of radially extending blades (3) that, distributed around the circumference of the impeller, form between them a number of flow channels (22:1-22:n).
    Type: Grant
