The Kim Chaek Iron and Steel Complex produced self-backing electrode based on domestic raw materials, thus providing a guarantee for increased production of iron and steel. It is also pushing ahead with the work to expand the production capacity of fire-proof material and improve its quality.

The Hwanghae Iron and Steel Complex is carrying out research projects related to the introduction of a comprehensive analysis system of oxygen heat blast furnace, in cooperation with a scientific research unit. It is also completing the work to introduce a method of producing iron and steel with active quicklime and a comprehensive inspection system of heavy rails.

The same is true of the Chollima Steel Complex.
