HYDROLOGY AND GEOCHEMISTRY OF A SLAG .

the initial reduction of raw iron ore. Blastfurnace slags volumetrically comprise most of the slag produced. Blastfurnace slags generally are 95 percent silicates and aluminosilicates of calcium and magnesium; the remaining 5 percent are composed of iron, manganese, and sulphur compounds, and other ironore impurities like phosphorous (Lank...

Basic oxygen furnace slag Euroslag

Basic oxygen furnace slag. Basic oxygen furnace slag BOS (also called LDconverter slag)is formed during the conversion of hot metal from the blast furnace into steel in a basic oxygen this process the hot metal is treated by blowing oxygen to remove carbon and other elements that have a high affinity to oxygen....

Production Process and Classification of Pig Iron – lifelarn

Oct 02, 2014· Pig iron is the basic material from which, wrought iron and steels are produced. It is obtained by smelting (chemical reduction) of iron ore in the blast furnace. In addition to iron, Pig iron contains varying quantities of other elements such as carbon, silicon, ....

FOUNDRY PIG IRON

gas leaves the blast furnace from the top as a blast furnace gas containing fiftyfifty carbon monoxide and carbon dioxide at the temperature of 200 degrees C after deoxidization of the iron ore in the granular zone. The ascending gas causes the temperature of the iron ore to rise to 800 degrees C in the granular zone. Then, the iron...

Characteristics and environmental aspects of slag: a review

In general, nonferrous slag may have a higher potential to negatively impact the environment compared to ferrous slag, and is thus a less attractive material for reuse, based on trace element chemistry, principally for base metals. However, the amount of elements released into the environment is not always consistent with bulk chemical ......

Electric arc furnace carbon steel slag (EAF) Products

An EAF produces steel by the melting of recycled steel scrap, using heat generated by an arc, created by a large electric current. The slag is formed through the addition of lime, which is added to remove nonessential elements from the steel. The slag has a lower density than steel and therefore floats on top of the molten steel....
