CAP Acero Huachipato steel plant (Planta Siderúrgica Huachipato) is a blast furnace-basic oxygen furnace (BF-BOF) steel plant in Huachipato, Talcahuano, Chile.[1] CAP Acero operates two blast furnaces (BF) and two basic oxygen furnaces (BOF).[2]

The CAP Acero steel plant, known in Spanish as Siderúrgica Huachipato, is Chile's only integrated steel mill.[1] It is owned and operated by Compañía Siderúrgica Huachipato S.A., the steelmaking division of Grupo CAP (Compañía de Acero del Pacífico, or Pacific Steel Company), a leader in Chile's iron mining and steel making industries.[3]

CAP was founded in 1946 as a joint venture between the Chilean government agency CORFO (33%), the Caja Autónoma de Amortización de la Deuda Pública (14%), and private shareholders (53%). The company, renamed Grupo de Empresas CAP in 1981, was entirely privatized in 1987.[4] Construction of the steel plant began in early 1947, and it was officially inaugurated on November 25, 1950.[5]

Since 1950 CAP has maintained its position as Chile's leading steel producer and processor, while steadily modernizing and upgrading its infrastructure.[1] [6] The plant's blast furnace/basic oxygen furnace system is fed with iron ore from CAP's own mines. The plant's continuous casting facilities and rolling mill transform the resulting steel into slabs, billets, and a variety of products destined for national and international markets, including cold- and hot-rolled steel, grinding bars, rebar, and wire rod for use in construction, mining and other industries.[7][2]

In 2013, the plant's blast furnace No. 2 was idled as part of a company-wide cost-cutting plan, but the furnace was reportedly brought back online in April 2019.[8]
