· Sinter presents better softening and melting behaviour than pellets or ore, but worse meltdown and high temperature gas resistance. It has been seen that a mixed burden containing 65 % sinter, 20 % lump ore, and 15 % pellets is slightly better than other compositions in terms of FT and ST, meltdown and high temperature gas resistance. In an another study it has been found that the .

· Increasing the basicity index CaO/SiO2 between and 3, chiefly through limestone admixture makes possible to reduce the thermal consumption of sintering and to improve the physical and chemical properties of the sinter. In the case of a plant using hematite ores, it seems interesting to produce an hyperbasic sinter and to complete the blast furnace burden with calibrated ore or acid .

· Sinter quality begins with the mined iron ore and the proper selection and mixing of the raw materials. Inhomogeneous raw mix can affect permeability and cause an increase in fuel consumption. During the iron ore sintering process in iron and steel manufacturing, an online analyzer can be used to determine the elemental composition of the bulk ...
Lump ore can bypass this process and be charged directly into the furnace, as can pellets, and both command an associated price premium. Most steel mills use a blend of different grades of ore, and a mix of sinter, lumps and fines, but the quality requirements depend on the circumstances and availability.
Sinter is agglomerate made of fine iron ore that is cheaper than pellets and lump iron ore and is superior in terms of reducibility and dropping characteristics. For the two reasons of better production cost performance and stable operation of blast furnaces, sinter has been used in Japan as one of the main sources for blast furnace operation. In order to satisfy the need to improve the ...

bentonite; pelletsinter composite agglomerate 1. Introduction Iron ore is available in nature in form of hematite, magnetite, goethite, limonite etc. Out of which hematite and magnetite are the major source. Hematite can be used directly in iron making furnaces in lump form. Magnetite is generally used after pre processing. In India, the graded hematite lump is widely used in the blast ...
