Blast furnace treatment of low grade manganese-iron

Blast furnace treatment of low grade manganese-iron ore . United States Patent 2265863 . Abstract: This invention relates to the pyrometallurgy of oxidic ores containing substantial amounts both of iron and of manganese, as opposed to ordinary iron ore containing only a few percent (e. g., 3% or less) of manganese compounds, and is concerned

Blast Furnace Process an overview ScienceDirect

2010-1-1  C.L. Nassaralla, in Encyclopedia of Materials: Science and Technology, 2001 1.2 Carbothermic Reduction. The blast furnace process is primarily used in the carbothermic reduction of oxides, such as iron, zinc, and lead. Most of the iron ore bodies commercially explored consist of iron oxides. Consequently, rich iron ore and/or iron oxide pellets formed from concentrate can be added

Blast Furnace Operation an overview ScienceDirect

Within the blast furnace, metallurgical coke is subject to a complex combination of thermal treatment, mechanical action, and chemical reaction with various gases, vapors, and liquids. The behavior of coke in this environment is a function primarily of the physical structure of

Blast furnace metallurgy Britannica

2 天前  Blast furnaces produce pig iron from iron ore by the reducing action of carbon (supplied as coke) at a high temperature in the presence of a fluxing agent such as limestone.Ironmaking blast furnaces consist of several zones: a crucible-shaped hearth at the bottom of the furnace

Optimization of blast furnace parameters using artificial

2015-12-16  In the blast furnace a very complex process takes place for the production of pig iron, which develops gradually as of the conventional furnace. A blast furnace melt downwards ore by the burning of the coke. Pig iron is produced as the output from the blast furnace by the series of several equations.

Injection of coal and waste plastics in blast furnaces

2019-12-11  important because of the affect on furnace permeability. Utilising injectants with a high burnout and optimising operating conditions, such as blast temperature and oxygen enrichment, can improve combustion efficiency. Interactions between coal and wastes plastics can be exploited to improve their combustion efficiency.
