effect of high manganese sinter in blast furnace

Effect of Oxides of Magnesium and Manganese and the

3/28/2016· It was established by laboratory studies and confirmed by factory tests that the filterability of molten blast-furnace slag is affected by the presence of the oxides MgO, MnO, and CaO, which are added to charge that is used to make sinter. The magnitude of this effect depends on the composition of the minerals that contain these oxides.

Effect of MgO on Emergence of Blast Furnace Primary Slag

Based on the furnace burden of high content of Al 2 O 3, the process of softening and melting and the characteristic of primary slag were studied with the increase of MgO content in the sinter and adding some MgO into the pellet.

Manganese Ore an overview ScienceDirect Topics

The maximum amount of sinter that can be fed to the furnace is a moot point and depends on its mineralogy and state of prereduction. When sinter replaces ore of high MnO2 content, the energy required in the furnace increases because the highly exothermic reduction of MnO 2, Mn 2 O 3, and Mn 3 O 4 no longer takes place in the furnace.

nodules or micro pellets for the sintering furnace. The material is fed to the furnace by a shuttle feeder system to form a level bed on the steel belt. Screened sinter pebbles are fed first on the bottom of the bed as hearth layer. Additional fine coke is fed on the surface of the bed, Figure 1. Manganese Ore

During re-oxidation and condensation of zinc in the up-per part of the blast furnace, heat is released again; how-ever its effi cient use is not possible any more. Only the blast furnace gas is heated and leaves the blast furnace. Due to this fact, it can be assumed that these processes
