The Ministry of Metallurgical Industry is striving to further refine the Korean-style iron- and steel-making methods.

The ministry has taken practical measures to further perfect the Juche-based iron-making system on the basis of the detailed analysis of the existing production conditions at the iron and steel production bases and the experience gained so far in putting the metal industry on a Juche basis.

Officials and workers of the Kim Chaek Iron and Steel Complex are intensifying a technical campaign.

Amid the strenuous activities of the April 15 technical innovation shock brigade, the complex is simultaneously pushing ahead with the work to raise the scientific level of all the processes for the production of Juche-based iron.

While giving precedence to technical preparations for remodelling the fire chamber of the concentrated ore drying furnace with emphasis put on increasing its capacity, blast furnace workshops Nos. 1 and 2 are conducting a vigorous mass technical innovation movement to supply raw materials and fuel according to standards, including the particle size of anthracite.

The oxygen plant branch factory, too, smoothly produces high-purity oxygen while regularly readjusting and reinforcing the air filter system.

Amid the growing enthusiasm of the producers at all workshops to improve technical indices and raise actual yield in all elements of production, the technicians and skilled workers of the complex are fully displaying their ability to step up the work to increase the productivity of oxygen blast furnaces and improve the quality of iron and steel.

The workers of the Hwanghae Iron and Steel Complex are also eager to consolidate the foundation for iron and steel production by dint of science and technology.

Though different in task, the technical innovation teams of the complex are putting spurs to the talent and research campaign with a desire to make new innovations in the production of iron and steel.

The technical innovation teams set high goals, including the one of increasing the productivity of the oxidizing roasting pellets over 1.5 times as compared to previously, and relevant technicians and skilled workers are pooling their wisdom and efforts without vacillation.

The work to introduce a production management system for the oxygen blast furnaces in close contact with a research group of the Metal Engineering Faculty of Kim Chaek University of Technology is also in full swing, thanks to the creative passion of the workers and technicians of the complex to increase the production of iron and steel and improve their quality.

Meanwhile, other different units of the metal industrial sector are stepping up the work to further perfect the Juche-based iron production system by fully relying on science and technology, including the Chollima Steel Complex which has pushed ahead with the work to determine a new iron production method.
