  • Agglomerates containing olivine for use in blast furnace
    Patent number: 4963185
    Abstract: A process for the reduction of iron oxides to produce molten iron in which olivine is introduced into a blast furnace in addition to iron oxide bearing materials and in which there is a high content of alkali metal oxides in the materials charged into the furnace, resulting in minimizing or preventing "scaffolding" and improving the operation of the furnace. The disclosure further includes improvements in which olivine is mixed with iron bearing materials or with coke and such mixture is formed into agglomerates having improved properties and in which such agglomerates are charged into the furnace.
    Type: Grant
    Filed: May 17, 1985
    Date of Patent: October 16, 1990
    Assignee: Applied Industrial Materials Corporation
    Inventors: Frank H. Ellenbaum, Richard Ciesco

  • Process of using olivine in a blast furnace
    Patent number: 3966456
    Abstract: A process for the reduction of iron oxides to produce molten iron in which olivine is introduced into a blast furnace in addition to iron oxide bearing materials and in which there is high content of alkali metal oxides in the materials charged into the furnace, resulting in minimizing or preventing "scaffolding" and improving the operation of the blast furnace. The disclosure also includes sinters and briquettes which contain olivine and processes of preparing them, and processes for furnace operation including the charging of such sinters or briquettes.
