Of Sintered Material Patents (Class 75/383)
  • Patent number: 9074870
    Abstract: The invention relates to a method and a device for sintering objects by means of time-resolved detection of two- or three-dimensional surface profiles and, optionally, by means of temperature measurement in a high temperature furnace on the basis of optical measurement methods. During sintering, each surface point on an object can be measured for its position and, optionally, its temperature, and a change can be determined by successive measurements. The measured change additionally permits control of the sintering regime. The method comprises the steps of: placing an object 4 into a high temperature furnace 5; heating the furnace 5; generating a two- or three-dimensional surface profile at least of a subregion of the object 4 by: irradiating the object 4 with light from a light source 2a; detecting the light scattered by the object 4 with the aid of a detector 2b; determining the geometric surface profile from the detected light.

  • Patent number: 8034157
    Abstract: A method and a device for charging feedstock, in particular coke or ore, and optionally separated fines of feedstock, for processing in a metallurgical vessel, to produce metal or primary metal products. The device includes a charging mechanism, which has a conveying device and at least one feeding device for supplying to the charging mechanism. The conveying device has an outlet opening which can be guided along an inwardly directed spiral during the charging into the vessel, to set a predefined coverage in the vessel. Charged materials can thereby be positioned precisely in the vessel, and it is possible for fines to be uniformly distributed in the circumferential region.
