The complex has paid attention to securing enough spare parts needed for normal operation of the furnace.

Its smelters have steadily improved the operation of the furnace by adjusting the mixing ratio of raw materials and fuel to shorten the melting time and explored and introduced technical innovation and rationalization proposals for increasing the amount of molten iron produced per charge.

Workers and technicians have put the operation of large oxygen separators on a normal basis while securing accessories by their own efforts.

The Chongam Mine and the Songphyonggwan Transport Station are operating long-range concentrated ore pipelines and vehicles in a scientific and technological way to supply raw and other materials in time.

With the operation technology of new oxygen heat blast furnace being steadily updated, the pig iron production at the complex is going up with each passing day.
