The Posan Line is an electrified freight-only railway line of the Korean State Railway in South P'yŏngan Province, North Korea from Kangsŏ at the junction of the P'yŏngnam and Taean Lines, to Posan.^[1]

The Korean State Railway is the operating arm of the Ministry of Railways of the Democratic People's Republic of Korea and has its headquarters at P'yŏngyang. The current Minister of Railways is Jang Hyuk, who has held the position since 2015.

South Pyongan Province is a province of North Korea. The province was formed in 1896 from the southern half of the former Pyongan Province, remained a province of Korea until 1945, then became a province of North Korea. Its capital is Pyongsong.

North Korea, officially the Democratic People's Republic of Korea, is a country in East Asia constituting the northern part of the Korean Peninsula, with Pyongyang the capital and the largest city in the country. To the north and northwest, the country is bordered by China and by Russia along the Amnok and Tumen rivers and to the south it is bordered by South Korea, with the heavily fortified Korean Demilitarized Zone (DMZ) separating the two. Nevertheless, North Korea, like its southern counterpart, claims to be the legitimate government of the entire peninsula and adjacent islands.

Services

The April 13 Ironworks at Posan produces pig iron, all of which is shipped to the Ch'ŏllima Steel Complex a short distance away at Kangsŏn on the P'yŏngnam Line, whilst using raw materials received from all over the western part of the country.^[2]

The April 13 Ironworks, one of North Korea's primary metal industries, is an ironworks in Posan-dong, Ch'ŏllima-guyŏk, Namp'o.Originally opened during the Japanese colonial era, it was nationalised after the partition of Korea and has been renovated several times, in the 1960s and again in the 1980s. As of 1997 it has a production capacity of hundreds of thousands of tons of pig iron, of which all is shipped to the Ch'ŏllima Steel Complex in nearby Kangsŏn.

Pig iron is an intermediate product of the iron industry, also known as crude iron, which is first obtained from a smelting furnace in the form of oblong blocks. Pig iron has a very high carbon content, typically 3.8–4.7%, along with silica and other constituents of dross, which makes it very brittle and not useful directly as a material except for limited applications. Pig iron is made by smelting iron ore into a transportable ingot of impure high carbon-content iron in a blast furnace as an ingredient for further processing steps. The traditional shape of the molds used for pig iron ingots was a branching structure formed in sand, with many individual ingots at right angles to a central channel or runner, resembling a litter of piglets being suckled by a sow. When the metal had cooled and hardened, the smaller ingots were simply broken from the runner, hence the name pig iron. As pig iron is intended for remelting, the uneven size of the ingots and the inclusion of small amounts of sand caused only insignificant problems considering the ease of casting and handling them.

The Ch'ŏllima Steel Complex in Kangch'ŏl-dong, Ch'ŏllima-guyŏk, Namp'o is one of North Korea's largest steel mills with an annual production capacity in the millions of tons. Originally opened during the Japanese colonial era as the Kangsŏn Steel Works, it was nationalised after the partition of Korea and has since been expanded several times.
