CMRDI STEEL TECHNOLOGY AND FERROALLOYS DEPARTMENT-Home

The steel and ferroalloys department is the heritage of the ferrous metallurgy unit established in 1960 as a part of the National research center. This unit mainly deals with bench-scale researches on iron and steel. The steel industry is considered a strategic industry. However, there is no steel industry without ferroalloys ore. It is well known that steel is the main constructional material in all other industries such as building, automotive, appliance. etc. Their means of production develop continuously from time to time. New grades of steel are developed to improve their characteristics which have a tremendous effect on the economy. Also, new technologies of production and treatment are taken into consideration the energy utilized and the environment. The same targets are also considered during the production and use of ferroalloys.

Steel Technology and Ferroalloys Department

is an experimental plant that deals with carrying out basic and applied researches in the field of special steels and ferroalloys however pilot and industrial plants researches are one of the main aims.
