F) ABSTRACT: The main method of production of the most common ferroalloys such as ferromanganese, ferrosilicon, ferrochromium is the electric furnace. The energy of this furnace is based on the combined use of electrical energy to create the necessary heat that is released in the area of the electrodes as well as in the charge when an electric current passes through it. The advantages and disadvantages of this method of supplying energy are well known. One of the disadvantages is increased energy consumption and reduced productivity. ORIEN Technology is a new method for producing of ferroalloys, which differs from the existing methods of using electric arc heating as a heat source, which is typical for electric arc steel furnaces operating with high electric voltage. The most characteristic feature of this innovative solution is the combination of raw material supply and carbothermic reductions by preliminary agglomeration ore (as raw materials) with carbon (as a reducing agent) and continuous supply of agglomerated materials into the combustion zone of the electric arc. This method is a further development of steel production technology - that bear the same name: ORIEN process. This new technology reduces energy consumption, increases productivity, expands the range of ferroalloys and improves their quality. This process can use natural ore as raw materials as well as poor ores with low content of alloy elements. |
