Firm Guarantee Provided for Attaining Iron and Steel Production Goal

Officials and workers of the Hwanghae Iron and Steel Complex are positively introducing our-style metallurgical technology to provide a sure guarantee for increased iron and steel production.

They successfully overhauled the １００-ton UHP electric arc furnace in April and improved the operation technology of the energy-saving oxygen blast furnace, thus opening up a prospect for increasing iron production.

The recent overhaul of the １００-ton UHP electric arc furnace was a stiff task including the dismantlement of high-heat equipment and the assembly of various apparatuses, which would have taken more than one month.

However, the officials and workers of the complex have completed the project on a high quality level by displaying the collectivist spirit of helping and leading each other forward, while shortening the period of the overhaul by half.

In the period, the hydraulic system, power unit and cooling equipment of the UHP electric arc furnace were replaced in a fresh way and technical transformation of some processes was also carried out in a substantial way.

After the successful completion of the project, all the processes of the １００-ton UHP electric arc furnace are in normal operation and the steel-making time is considerably shortened.

The complex has also made a progress in the work to perfect the energy-saving oxygen blast furnace in a technical way.

Now, the workers of the blast furnace workshop are making innovations while vigorously conducting production emulation by shift for turning out even a ton of molten iron according to the updated technical indices of the energy-saving oxygen blast furnace.
