WebImprovement of Sinter Quality 3.1 Improvement of blast furnace operation by decreasing SiO 2 and MgO contents in sinter As seen with Figs. 1 and 2, the studies confirmed the excellent reduction behavior of high-Fe sinter at high temperatures. Aiming at lowering the SiO and MgO contents in sinter and improving its WebIn this work, sinter quality for improvement in gas permeability of blast furnace was investigated with reduction degradation and under-load-reduction tests. As the results, the reduction degradation of sinter is deteriorated by increasing H 2 concentration in the reduction gas under the condition of below 3.8 vol% H 2.
WebAug 2, 2012 · On the other hand, it is argued that the process of liquid-phase reduction – not two-stage processes such as Corex or Finex – can be an alternative to blast-furnace smelting [ 5 ]. At the same time, a number of experts believe that there are still ways to further improve the coking/sintering/smelting process.
WebThe sintering process is an important thermochemical process in the blast furnace ironmaking system.
