At the plant these are initially stored with the help of a stacker in piles. Different reclaimer types are used to reclaim the materials from the piles and discharge to different conveyors for delivering the materials to the main plant. 4. Sinter plant: Prior to sending iron ore it is sintered at the sintering plant along with limestone and ...
Jun 15, 2010· Iron ore fluxed sinter is the main ferrous burden of Jindal south west steel limited (JSWSL) blast furnaces. In sinter plant fluxes including limestone and dolomite are added to improve the sinter properties of iron ore and to provide an appropriate slag composition of the blast furnace.
Our chemical grade limestone is used in the ironmaking process to produce the slag, which removes impurities from the iron ore while making liquid pig iron. Our limestone is added to iron sinter and pellets to add flux and promote agglomeration in your products. Blast furnaces can add limestone directly to the burden to promote slag formation and protect the refractory.
The iron ore sintering process prepares fine iron the ores for the blast furnace process. sinter plants agglomerate iron ore fines with other fine materials at high temperature in a mix bed to create a product that can be used in a blast furnace. main feed into a sinter plant is base mix, which consists of iron ore fines, coke fines and flux ...
ABSTRACT: Sintering is a process by which a mixture of iron ores, fl uxes and coke is agglomerated in a sinter plant to manufacture a sinter product of a suitable composition, quality and...
Sintering of Iron Ore Our quality limestone and burnt products with optimized size distribution impacts the environmental footprint of the mill by improving the sinter productivity and reducing overall energy cost and emissions.
Sinter improves blast furnace operations by combining the blast furnace flux into the sinter rather than charging it separately to the top of the furnace. Iron ore fines, limestone and dolomite form agglomerated sinter through low temperature ovens.
FUNDAMENTALS OF IRON ORE SINTERING R. P. Bhagat INTRODUCTION The process of sinter making originated from a need to make use of fines generated in mines and in ore benefiCiation plants. With the development of sintering technology, a sintering plant has become a tremendous success for providing a phenomenal increase in
Iron ore fines, coke breeze, limestone and dolomite along with recycled metallurgical wastes are converted into agglomerated mass at the Sinter Plant, which forms 70-80% of iron bearing charge in the Blast Furnace. Iron and Steel Lhoist - Minerals and lime producer Finely-crushed limestone is used as a flux in iron ore sintering.

May 08, 2013· Limestone and dolomite flux and their use in iron and steel plant. Limestone is a naturally occurring mineral. The term limestone is applied to any calcareous sedimentary rock consisting essentially of carbonates. The ore is widely available geographically all over the world. Earth’s crust contains more than 4 % of calcium carbonate.

Sintering: A Step Between Mining Iron Ore and Steelmaking. According to the U.S. Environmental Protection Agency, the sintering process converts fine-sized raw materials, including iron ore, coke breeze, limestone, mill scale, and flue dust, into an agglomerated product, sinter, of suitable size for charging into the blast furnace.
World resources are estimated to be greater than 800 billion tons of crude ore containing more than 230 billion tons of iron. The only source of primary iron is iron ore, but before all that iron ore can be turned into steel, it must go through the sintering process. Sinter is the primary feed material for making iron and steel in a blast furnace.
Iron ore pellets are spheres of typically 6–16 mm (0.24–0.63 in) to be used as raw material for blast furnaces.They typically contain 64–72% Fe and various additional material adjusting the chemical composition and the metallurgic properties of the pellets. Typically limestone, dolomite and olivine is added and Bentonite is used as binder.. The process of pelletizing combines mixing of ...
Iron ore fines, coke breeze, limestone and dolomite along with recycled metallurgical wastes are converted into agglomerated mass at the Sinter Plant, which forms 70-80% of iron bearing charge in the Blast Furnace. The vertical speed of sintering depends on …
