Background
History
In 1942, Japan Iron and Manufacturing Company began a plant in Chongjin with 2 500-tonne blast furnaces (BF) (total capacity of 1000 TPD), 2 batteries of 57 coke ovens (total capacity of 1240 TPD), and 2 7-tonne electric arc furnaces (EAF) .[ 1] There was also a direct reduced iron (DRI) plant on site, founded by Mitsubishi Mining Company in 1939.[ 1] During the Seven-year Plan (1961-70), the existing two large blast furnaces were enlarged and three medium-size blast furnaces were installed subsequent to 1965.[ 2]
Steel for weapons development
In March 2020, Daily NK reported that North Korea is aiming to increase its production of steel for weapons development, with the goal of selling these weapons abroad for foreign currency.[ 3]
