Sinter plant at Ispat Steel, India. Many countries, including India, France and Germany, have underground deposits of iron ore in dust form (blue dust). Such iron ore cannot be directly charged in a blast furnace. In the early 20th century, sinter technology was developed for converting ore fines into lumpy material chargeable in blast furnaces ...
During this period, pellet sintering developed alongside grate sintering as an alternative process to address the agglomeration challenges faced by high-quality iron ore products. [1] The concept of pellet agglomeration was initially patented by A. Anderson in Sweden in 1912, followed by a similar patent in Germany in 1913. [ 3 ]
Liquid phase sintering is the process of adding an additive to the powder which will melt before the matrix phase. The process of liquid phase sintering has three stages: rearrangement – As the liquid melts capillary action will pull the liquid into pores and also cause grains to rearrange into a more favorable packing arrangement.
Pieces of agglomerate produced by the Dwight-Lloyd process, laid on an A4 sheet. Agglomerate is a material composed of iron oxides and gangue, roasted and sintered [notes 1] [1] in an agglomeration plant. This product is obtained by burning coal previously mixed with iron ore and oxides. This conditioning of iron ore optimizes its use in the ...
Ironton Sintering Plant Complex is a group of buildings north of Crosby, Minnesota, United States, listed on the National Register of Historic Places. The plant was built in 1924 by the Hanna Mining Company to sintering iron ore mined in the Cuyuna Range. The mining industry, after 1900, was seeking to exploit lower-grade iron deposits to meet ...
Pelletizing is the process of compressing or molding a material into the shape of a pellet. A wide range of different materials are pelletized including chemicals, iron ore, animal compound feed, plastics, waste materials, and more. The process is considered an excellent option for the storage and transport of said materials. [1]
Sinter plant, in which iron-ore dust gets mixed with other fine materials at high temperature, to create a product – sinter – for use in a blast furnace; Sintering, a high temperature process for fusing powder together; Calcareous sinter, calcium carbonate deposited by springs; Siliceous sinter, silica deposited by hot springs and geysers
The Corex Process is a smelting reduction process created by Primetals Technologies as a more environmentally friendly alternative to the blast furnace. [1] Presently, the majority of steel production is through the blast furnace which has to rely on coking coal [2] and requires a sinter plant in order to prepare the iron ore for reduction. [3]
