CSN Volta Redonda steel plant

From Global Energy Monitor

CSN Volta Redonda steel plant (Usina siderúrgica CSN Presidente Vargas (Portuguese)), also known as Presidente Vargas Steelworks, is a 6250 thousand tonnes per annum (TTPA) blast furnace (BF), basic oxygen furnace (BOF) and electric arc furnace (EAF) steel plant operating in Volta Redonda, Rio de Janeiro, Brazil.

CSN (Companhia Siderúrgica Nacional, or National Steel Company) is the largest fully integrated steel producer in Brazil and one of the largest in Latin America in terms of crude steel production, with an annual capacity of 5.8 million tons. Its main plant is located in the city of Volta Redonda, in the state of Rio de Janeiro, Brazil.[2]

CSN was created as a state-owned company on April 9, 1941, during the administration of Brazilian president Getúlio Vargas, with the objective of building a large national steelworks to satisfy growing demand, make use of the country's abundant mineral resources, and strengthen the national economy.[3] In 1946, steelmaking began at the newly constructed Presidente Vargas Steelworks in Volta Redonda, with iron ore for the blast furnace supplied by the Casa de Pedra and Arcos mines recently acquired by CSN.[4]

The Volta Redonda plant significantly expanded its output over the next four decades, with the installation of two new blast furnaces (BF #2 and #3) in 1954 and 1976, respectively; the plant's original blast furnace #1 was decommissioned in 1992.[5] Steel production rose from 680,000 tons per annum in 1954 to 1.3 million tpa in 1963, 2.5 million in 1977, and 4.6 million in 1989.[4]

In 1993 the company was privatized in accordance with Brazil's National Program for Privatization, with the Brazilian government selling 91% of its shares to private investors on the Rio de Janeiro stock exchange. A period of capital improvements and productivity initiatives followed, culminating in 2001 with the revamping of blast furnace #3 and hot strip mill #2 to increase the plant's capacity to 5.6 million tpa of crude steel and 5.1 million tpa of rolled products. In 2003, annual production reached a new high of 5.3 million tons.[4]

In 2013, after more than half a century specializing in flat steel, the Presidente Vargas Steelworks inaugurated a new long steel plant equipped with an electric arc furnace, continuous casting facilities and a hot rolling mill designed to supply up to 500,000 tpa of long steel products for Brazil's civil construction industry.[4][6]

Today CSN's Volta Redonda steel complex manufactures a broad variety of steel products, including slabs, hot- and cold-rolled steel, galvanized steel, rebar, wire rod, and structural shapes.[7] Its products are used by the automobile, auto parts, civil construction, electrical equipment, and packaging industries.[8]
