Patents by Inventor Hans Herbert Stiasny

Hans Herbert Stiasny has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8641799
    Abstract: A process for producing agglomerates from fine-grained iron carriers and at least one binder as a charge material for a metallurgical process is shown. In at least one further agglomeration step, the agglomerates are coated with a layer, comprising iron carriers and at least one binder, and heated in such a way that the binder is cured in the region of the surface of the agglomerates. In a process for producing liquid pig iron or liquid primary steel products from charge materials and possibly additions and agglomerates, the agglomerates are preheated in a reducing zone, which has a preheating stage, in such a way that the agglomerates completely harden in the preheating stage.
    Type: Grant

  • Patent number: 7914731
    Abstract: A process for sintering metal-containing materials, such as iron ores or manganese ores, on a sintering machine including a sintering belt for transporting the sinter mix during sintering thereof. The sintering belt has first, second and third portions. Sintering waste gas from the third portion is transported to and unified with sintering waste gas from the first portion in a mixing region to form a mixed gas, wherein the transporting distance of the sintering waste gas from the third portion to the mixing region is greater than the transporting distance of the sintering waste gas from the first portion to the mixing region. An apparatus for carrying out the process is disclosed, including the sintering belt, suction boxes operative at the portions of the belt, and lines for conveying the gas produced and the gases used in the process.

  • Patent number: 7811086
    Abstract: The invention relates to a feeding device for a belt-type sintering machine, with a feeding container for receiving the material to be sintered, with a conveying device for filling the feeding container with material to be sintered, with a feeding drum and a drum chute for feeding the material to be sintered onto the sintering belt. The feeding container has two discharge openings, one of which is connected to a feeding drum and one of which is connected to a feeding chute.
