Kim Chaek University of Technology has recently produced lots of good research results leading economic growth.

Above all, it has solved scientific and technological problems essential for putting power generation on a normal track.

The automatic power factor controller developed by the Electric Power System Institute of the Mirae Sci-Tech Centre under the university makes it possible to comprehensively measure power factors even under the condition that different motors work separately and accordingly compensate for the power factors by way of automatically turning on the power capacitors at workplaces.

The Electric Engineering Faculty developed an automatic power factor compensator.

It automatically predicts and controls power factors, unaffected by any variations in load, voltage and frequency, thus reducing loss of electricity and ensuring safe operation of electrical equipment.

The Nano Sci-Tech Institute realized the domestic production of a nano composite plastic belt with good specifications which is badly needed in mining and light industries and different other economic sectors.

It is superior to polyvinyl chloride in tensile and impact strength, hardness and elastic modulus and its production cost is 40 percent lower than the imported one. According to its developers, they introduced it to flow lines of 20-odd factories and enterprises, including a drying flow line of the Sariwon Students’ Shoes Factory, to fully prove its technical efficiency.

The institute also established a highly efficient hydrogen production technology using a nanocatalyst.

They developed the nanocatalyst to get hydrogen, widely used as a raw material in the chemical industry and as a source of green energy, in a higher degree of efficiency with less power and made a hydrogen generator using it. It is a big step forward made in the development of the energy industry of the country.

The Earth Science and Technology Faculty developed a Korean-style outdoor gamma spectrometer capable of immediately analysing the radioactive intensity and contents of radioactive elements in mineral rocks and soil in the prospecting field.

The researchers designed it in conformity with the specific conditions of the country and applied such technologies as a high-speed analogue-to-digital conversion and a high-speed parallel processing to make the highly accurate analyser ensuring spectrum stabilization. It enabled the users in the field to obtain highly accurate measurements in less time than previously. Shortly ago, it was registered as a high-tech product as it helps increase the speed and efficiency of prospecting remarkably with less time, labour, reagents and other materials than previously.

In addition, the university solved many sci-tech problems including a highly profitable drawing technology, iron-making technology using reduced iron in a medium frequency induction furnace and an electrical pulse water treatment technology.
