Iron and steel manufacturing is one of the most energy-intensive industries worldwide. In addition, use of coal as the primary fuel for iron and steel production means that iron and steel production has among the highest carbon dioxide (CO 2) emissions of any industry. According to the
A sinter plant, which was originally developed to convert the iron ore fines into a desirable blast furnace feed further, offers very potent route of recycling for a large number of wastes in various quantities . Steel slag with CaO content above 50% can be used as sinter ore fluxing agent, partially replacing the commercial lime.
The iron ore, coal/coke/char (as carbon) and any available cheaper energy source (furnace oil, producer gas or pulverized coal) would be required as raw materials. The waste fines from mine (iron ore /coal), washeries (coal) and steel plants (ore /coke/ coal fine) may be the source of such raw materials.
Fig. 8 : Iron ore sintering machine The modern sintering machines are provided with efficient burners, larger sinter bed area, heat recovery system from hot sinter, air and thermal emission abatement devices etc. In India there are 34 sinter making machines with some steel plants with capacity to produce 49 million ton sinter as shown in Fig. 9.

May 14, 2018· Iron ore is generally processed in sintering plants into sinter, and in some cases in pelletizing plants to iron ore pellets. Iron ore sinter and pellets are then charged together with coke from ...
• Iron ore fines are a product of the screening of iron ore • They are used to ... However Iron ore sinter feed and pellet feed are classed as Group A. ... India major exporter to China. Chinese imports of iron ore – year 2000 = 75 MT – year 2008 = 500 MT. SUMMARY
The huge steel output has made it impossible for the domestic iron ore deposits to meet the demand for iron ores. In fact, a major part of the iron ores consumed rely on imports. Australia, Brazil, Canada, South Africa, etc. are the main iron ore exporters, and the long-term data show that the iron ores imported by China have even exceeded 90% ...
The product is "pig iron", used in foundries to make a variety of castings such as car engine blocks, and parts for light and heavy machinery. Pig iron is usually remelted and suitably treated to make castings. ''Cast iron'' is therefore more highlyrefined than ''pig iron''.
ments. In these experiments, the iron ore blends of base tests were similar to the blends used in commercial sinter plants. Generally, the iron ore concentrates were increased to replace Brazilian ores (or both Brazilian and Australian ores); and low grade ores were increased to replace Australian ores. The sinters were controlled at the same
Iron ore and other iron-containing materials may be agglomerated in sinter plants at integrated iron and steel plants prior to introduction into the blast furnace. Feedstock to sinter plants may include fine iron ores, additives (e.g., lime or olivine), and iron-bearing recycled materials from downstream
If above expected quality sinter will be replaced with iron ore in blast furnace, maximum ratio (80 - 85 %) of sinter can be used safely. Production cost of the sinter has to be considered while using the sinter in blast furnace which is depending on the cost of raw materials for sinter making.
Jun 11, 2017· 2. In pellets porosity is more at surface whereas in sinter porosity is spread almost homogeneously . 3. Pellet is made in the presence of moisture and binder with subsequent induration at 1300°C whereas sinter is prepared in sintering Dwight Lloyd machine. 4. Pellet has more thermal efficiencies as compared to sinter. 5.
By 2008 raw materials such as Iron ore prices grew and China had to reluctantly agree to price increases by the three largest iron ore producers in the world; BHP Billiton, Rio Tinto and Vale. During the Global financial crisis the Chinese steel mills won price reprieves as demand from their customers slowed.
The characteristics of these raw materials strongly affect the metallurgical properties of iron ore sinter and sinter plant performance. An optimal ore blend design is therefore essential to produce low cost and high quality hot metal. Without doubt, some hazardous components are brought into the production process, and therefore, there are some associated pollutants. A good preparation of raw materials is .
