Keywords: sintering process, laboratory sintering pan, infrared thermography, temperature control 1 Introduction Sintering is an agglomeration process in which iron ore fines and other products such as coke fines (or biomass) and basic materials are mixed and fired at a temperatures 1200 – 1350 °C.
Dec 28, 2015· History of sintering of iron ore. Middle of nineteenth century, small sintering pot used to be constructed in the copper mining in England. The origin of sintering process goes back to 1887 when F. Haberlein and T. Huntington of England invented the process of agglomeration for sintering …
The invention claimed is: 1. An ore fine agglomerate to be used in a sintering process, comprising: ore fine particles, an agglomerating agent comprising sodium silicate, and microsilica as an additive in a range of 0.3% to 1.0% by mass, wherein a ratio of the ore fine particles and the agglomerating agent is about 0.5 to about 5.0% by mass of the agglomerating agent, and wherein the ore fine ...

Mar 09, 2013· The process of sintering begins with the preparation of the raw materials consisting of iron ore fines, fluxes, in-plant metallurgical waste materials, fuel and return fines of the sinter plant. These materials are mixed in a rotating pelletizing drum and water is added in order to reach proper agglomeration of the raw materials mix.
I am fascinated with sintering since I can use sintered metals formed to act as filters; these kinds of filters can remove debris smaller than 0.5 µm. Iron making plants probably do NOT make sintered metal granules. Iron is just ONE of many metals...
