A technical remodeling is progressing apace to put the metallurgical industry on a Juche basis by rounding off the Juche-based iron production system technologically while increasing the production at major metallurgical factories.

The Kim Chaek Iron and Steel Complex strives to provide a guarantee for further improving the quality of rolled steel at an oxygen converter while perfecting the process of iron and steel production.

The Hwanghae Iron and Steel Complex deepens the research into energy-saving blast furnace and refining process, pushing ahead with the work to meet the growing demand for iron and steel through the establishment of a new iron production process.

The Chollima Steel Complex has directed efforts to lowering the production cost by introducing the oxygen-pulverized coal injection technology into UHP electric arc furnace, in cooperation with scientific institutes, and building new gas generators.

Meanwhile, the Posan Iron Works is speeding up the work to lower the cost of Juche-based iron production through the introduction of a new blast technology.
