The remaining methods for making steel do so by removing impurities from pig iron or a mixture of pig iron and steel scrap. The impurities removed, however, depend on whether an acid (siliceous) or basic (limey) slag is used.
The reduction behaviour of magnetite oxide by hydrogen below Curie temperature was investigated in the presence of external magnetic field by thermogravimetric analysis. The reduction rate of magnetite powder increased with increasing external magnetic field strength below Curie temperature of magnetite. In order to figure out the effect of external magnetic field on reduction of magnetite ...
The result of magnetic separation of synthetic slag showed that iron rich phase is recovered readily at 0.07 magnetic field intensity (T),intermediate phase dicalcium ferrite is recovered at field intensity (T>0.3) whereas dicalcium silicate will have no effect (Fig). This result was applied on as received and slowly cooled slag.

Steel is made by the Bessemer, Siemens Open Hearth, basic oxygen furnace, electric arc, electric high-frequency and crucible processes. In both the Acid Bessemer and Basic Bessemer (or Thomas) processes molten pig iron is refined by blowing air through it in an egg-shaped vessel, known as a converter, of 15-25 tonnes capacity.
Ball Mill. Ball mill is the key equipment for grinding after the crushing process, which is widely used in the manufacture industries, such as cement, silicate, new building material, refractory material, fertilizer, ferrous metal, nonferrous metal and glass ceramics and can be used for the dry and wet grinding for all kinds of ores and other grind-able materials.
The steelmaking slags are referred to by the steel production techniques used, such as BOF, EAF, and ladle furnace etc. These steel making slags typically contain 20–25% iron (Kawatra and Ripke, 2002).Because the chemical composition of steel slags is highly variable, the mineral composition of steel slag .
