At the Hwanghae Iron and Steel Complex

Preparations have been made for the general trial run of the energy-saving oxygen heat blast furnace to be newly built at the Hwanghae Iron and Steel Complex, a major iron and steel production base.

The Party guidance team, the Ministry of Metal Industry and the complex unfolded an economic operation for consolidating the iron and steel production foundation in a scientific and energetic way.

Those in charge of the control of the Juche-based remodeling project propelled the implementation of the incomplete construction tasks and pushed ahead with the trial operation of the systems at the same time now that most of the construction was completed.

Meanwhile, they developed the initiative and creativity of workers and technicians on the spot and supplied necessary equipment and installations in time in close contact with the relevant unit.

The workers of the complex focused efforts on perfecting all the systems of the newly-built oxygen heat blast furnace on a high qualitative level while devising and introducing technical innovation proposals and rationalization plans based on the past successes and experiences.

The officials of the complex promptly solved the knotty problems in the systematic trial run through repeated field consultations.

The scientific research and technical group rectified the shortcomings that occurred during the trial operation by arranging some equipment and installations in a rational way and conducting the technical renovation of equipment by pooling creative wisdom with the field workers.

Along with this, they concentrated on establishing appropriate techniques of furnace operation and rational furnace management methods with which to increase molten iron output while saving raw materials and fuel.

At the Posan Iron Works

The Posan Iron Works steadily makes preparations for normalizing production in a foresighted manner after successfully conducting the load trial of a vertical furnace for oxidizing roasting pellet.

Its officials and working people gave precedence to the manufacture of installations and steel structures needed for the furnace construction by securing various jigs and tools beforehand and renovating the equipment in technological terms through technology and experience sharing.

They made tireless efforts to design the processes in our way with focus placed on ensuring scientific accuracy of the design.

Therefore, they successfully built the vertical furnace for oxidizing roasting pellet by completing the construction work of several production buildings in just a few months and stepping up the assemblage of steel structures and equipment and installations.

The iron works ensured the smooth systematic no-load trial run based on such achievements and continuously made the load trial.

The officials of the Ministry of Metal Industry and the iron works solved the problems which presented themselves in the load trial by intensifying cooperation with relevant units.

In particular, they gave scientific guidance with the main stress on raising the operation rate of the furnace.

The workers and technicians channeled efforts into defining rational technical indices for normalizing the operation of the furnace while overcoming the shortcomings revealed in the process of the load trial and adopting new technological plans.

At the Chongjin Steel Plant

Successes of the overall reconditioning of the revolving furnaces are augmented day after day at the Chongjin Steel Plant.

After overhauling two revolving furnaces in the first half of the year, the workers further heightened their spirit and buckled down to the overall reconditioning of the revolving furnace No. 1.

Thanks to the well-knit plans of the officials and devoted efforts of the workers and technicians, the heavy frame of the furnace has been assembled and the support rollers installed successfully and the project entered its final phase.

The project is sped up day after day amid the substantial summing-up and elevated enthusiasm for socialist emulation among units.

The workers and technicians of the steel plant invented and applied fresh and original construction methods and rational technical innovation schemes to assemble and install the steel structures in a short period. They also shorten the construction date by producing several accessories and spare parts with existing processing equipment.

Along with this, they find out one by one accurate sci-tech measures with which to raise the temperature of the revolving furnace while lowering the standard of material consumption per unit through brisk mass-based technical innovation drive.

The officials make scientific and detailed organizations and give priority to supplying raw and other materials, thus making sure that the high enthusiasm of the masses leads to actual results in construction.

Consequently, a bright prospect for decisively increasing the production of samhwa iron next year is being provided.
