Sponge of iron process formula
Do you know what is sponge iron specification? An important component in the production of steel is sponge iron. This is obtained in the direct reduction plant from the reduction of the iron ore that arrives in the form of “pellets” or as calibration.
It is called “sponge iron” because extracting oxygen from iron ore produces a porous and relatively light metal product. The raw material for obtaining sponge iron is iron ore (iron oxide). This, like coal and dolomite, are stored in silos before entering the kilns.
In rotary kilns iron ore is reduced, freeing it from oxygen thanks to the action of coal, in order to transform the greater proportion of iron to its metallic state and use it in the electric furnace as a metallic charge in the manufacture of steel, with the advantage of obtaining a product with less amount of residuals and better properties.
How is oxygen extracted from iron ore? Iron ore, along with coal and limestone, enter the rotary kilns in adequate proportions through the use of weighing scales (weight feeders) and the residence time inside is controlled by the rotation speed. The interior of the furnaces is covered with refractory material to avoid thermal losses.
The sponge iron obtained then passes to the rotary cooler where, through an indirect heat exchange with water, the temperature is lowered to approximately 100 ° C.
It is then classified by size and via magnetic separators, where the sponge iron is separated from the coal and ash residues, so that finally the metal load thus obtained is stacked in the metal consumption bay awaiting its use. The coal residues are then concentrated for reuse in the process.
Latest price list for sponge of iron
The sponge of iron is a form that the iron takes once it is melted. they are iron balls with a certain amount of air making it more manageable and transportable than if it were melted into ingots (bar or piece of metal).
in this way you can even handle with shovels, transport more, load and unload faster, as such it has no applications, it is only the raw material for everything made with iron, such as rods, blacksmith profiles, steel, etc.
these products available in wholesalers and reliable dealers. in this site, applicants and bulk buyers can contact to our sale expert and ask sponge iron prices and other information.
