Efforts are directed to the work for putting production lines at major iron and steel plants on the basis of advanced technology.

Officials and working people in the Hwanghae Iron and Steel Complex, in cooperation with various research institutes, resolve problems arising in technically rounding off the ore-dressing line for producing concentrated ore with locally available materials.

Those at the Kim Chaek Iron and Steel Complex exert their efforts on the work for increasing the productivity by pressing ahead with the technical updating of production lines.

Researchers at the May 28 Metal Research Institute under the Ministry of Metallurgical Industry intensify their research to provide a guarantee for further enhancing the quality of desulphurizer of oxygen heat blast furnace and ferroalloy, while resolving technical problems arising in putting the iron production on a normal basis.

Designing organs have made positive contributions to the technical updating of production lines by completing the designs for the Juche-based projects.

Successes are also witnessed in the Juche-based projects including the construction of energy-efficient iron blast furnace.
