Pyongyang, June 16 (KCNA) -- The Sunchon Chemical Complex in the DPRK has recently built a vertical oxygen-blast furnace with indigenous technology to produce pig iron without using cokes. This furnace makes it possible to use natural ironstone and anthracite and even various kinds of low-grade iron ore as raw materials. Its smelting-reduction process was proved through full operation to be a highly-efficient iron-making process that can mass-produce pig iron with 100 percent domestic raw materials and fuel. The Ferrous Metal Research Institute of the State Academy of Sciences and the complex jointly set up a combined automatic control system for the Juche-based iron-making process. They also developed a new technology for collecting and using waste gas from the furnace and modernized its dust-collection system. |
