مصنع لتجهيز البوكسيت/Quantity Required For Making One Tonne Sponge Iron Processing
Directreduced iron has about the same iron content as Pig Iron, typically 90–94% total iron (depending on the quality of the raw ore) as opposed to about 93% for molten pig iron, so it is an excellent feedstock for the electric furnaces used by mini mills, allowing them to use lower grades of scrap for the rest of the charge or to produce higher grades of steel.

Require time to melt 1000 kg (1 ton) of cast iron is depends on the usage of power consumption from the power supply unit. If the capacity of the power supply is 500 kW and you are operating it on the full power means 500 kW than melting time can be calculated from below equation.
· Fig 2 Principle of direct reduction process. Gas based process. In the gas based reduction processes, a vertical shaft kiln is used in which iron ore is fed into the top of the kiln and finished sponge iron is drawn off from the bottom after cooling it so as to prevent its reoxidation.
Assume some iron is lost as FeO in slag. Per ton of pig iron there is tons of ore is used Determine: of coke/ton of pig iron. omposition of slag/ton of pig iron. c) Perform oxygen balance and comment.

1. Krupp Sponge Iron Process The Krupp. Sponge iron process uses a rotary kiln for the reduction of high grade lump ores or pellets (Fig. 1). The feed is introduced together with reducing and desulphurizing agents (limestone or raw dolomite) into an inclined rotary kiln, heated counter current to the flow of hot gas and reduced to form sponge ...
This combines with the iron oxides in the iron ore to produce metallic iron known as pig iron. Pig iron is obtained in a molten state that can be moulded as required. It contains a comparatively higher quantity of carbon, about %, and is less pure than sponge iron.
World exports, 2015 (Mt) 1 447 1 308 2 216 Iron ore Steel is an alloy consisting primarily of iron and less than 2% carbon. Iron ore is, therefore, essential for steel production, which is essential in maintaining a strong industrial base. 98% of mined iron ore is used to make steel. Iron is one of the most abundant metallic elements. Its ...
