Pyongyang, July 30 (KCNA) -- The metallurgical industry sector of the DPRK consolidates the existing production foundation while steadily increasing its scientific and technological capabilities.

The Kim Chaek Iron and Steel Complex introduced a rational technical innovation proposal to raise the quality of steel, the actual extraction rate of ingoting and rolling while reducing the consumption of ferroalloy. By doing so, it increased the pig iron output 1.4 times as against the same period of last year.

The workers and technicians of the rolling shop of the Chollima Steel Complex have made successes by positively introducing valuable technical innovation proposals and inventions.

The Musan Mining Complex succeeded in several rounds of medium and small blasts, providing a guarantee for the successful blasting of 2 500 000 cubic meter earth.

The Unryul and Jaeryong mines are directing efforts to ensuring the full operation of mining equipment and vehicles and producing more iron ores through a brisk mass technical innovation movement.

The Posan Iron Works, the Hungnam Electrode Factory, the Puryong Ferroalloy Factory and the Jangsan Mine are fulfilling their high production plans while solving the sci-tech problems arising in modernizing and operating equipment. -0-
