The oxygen heat blast furnace shop and the oxygen separator branch factory of the Kim Chaek Iron and Steel Complex introduced an advanced charging method and managed equipment in a sci-tech way to make innovations in the production of molten iron and oxygen.

The workers of the hot-rolling shop launched a mass technological innovation movement to produce much more quality rolled steel, and other shops, too, have carried out their daily plans without fail.

All units under the Musan Mining Complex operate equipment at full capacity so as to implement their daily plans without fail.

The same is true of the Puryong Ferroalloy Factory.
