The Department of Industrial Furnace Engineering of the Faculty of Metal Engineering has developed in Korean way a switching valve, which constitutes the two core elements together with the honeycomb regenerator in high-temperature air combustion (HTAC) technology, which proves effective in putting Juche iron production on normal footing.
The research team led by Department chief Kim In Gyu set the switching valve in a 3 channel switching mode to suit the characteristic features of the high-temperature air combustion furnace in which gas is alternatively combusted on both sides of the combustion chamber, and selected the compressed air-type driving mode, which is simple in structure, and very reliable and swift in action.
They checked up the stability of valve surface and axis with the structural mechanical and hydrodynamic characteristics based on computer simulation, and designed a rational structure dimension of body according to the opening height with minimum pressure loss and the input-output diameter of air and waste gas.
The switching valve has been recognized as a research achievement of great economic value as it is applicable to large furnaces, does not make much noise, and is free from any waste gas leakage and risk of explosion.

Mt. Paektu, the ancestral mountain of Korea and the sacred mountain of the revolution, is the focus of attention of volcanologists in many countries around the world as a dormant one.
A Mt. Paektu volcano research group consisting of geophysicists from the Resources Probing Engineering Faculty including Kim Kang Sop, a department chief of the faculty, and the Academy of Engineering Science has been conducting systematic research into Mt. Paektu volcano since the beginning of the present century based on its over 30 years of experience on magnetotelluric method.
The focus of the research was to shed light on the magma shape and its movement deep underground as clearly as possible by combining the magnetotelluric (MT), gravitational and magnetic survey and volcanic fluid dynamic simulation. Research results on the MT data processing, cross gradient joint inversion, body growth inversions of gravity data were made public through three papers in the Journal of Applied Geophysics, the SCI magazine.
The research results on the 3D HT dynamics of Mt. Paektu volcano based on the geophysical survey data were issued in the International Seminar on the Research of Mt. Paektu Volcano at the Sci-Tech Complex cosponsored by MPGG and PIINTEC in August Juche 105(2016), and the Future Research Project on Mt. Paektu Volcano in the Royal Society in June Juche 106(2017).

The 33rd National Festival of Science and Technology was held at the hall of new technology of the Three-Revolution Exhibition House from April 23 to May 4.
Kim Chaek University of Technology presented more than 30 proposals selected from its sci-tech festival last February.
The festival drew a special attention of lecturers, researchers and postgraduate students as it opened in this significant year that marks the 70th anniversary of the founding of the DPRK and the university.
In the festival, two proposals including “Vacuum pressure impregnation process (VPI) by Pak Kil Hung, a department chief of the Electric Engineering Faculty, took the top place, 12 proposals including “Plasma-based environment improving technology” by Ri Thae Nam, a department chief of the Physical Engineering Faculty, won the first place and 11 proposals including “Several types of fractional non-linear chaos simulation systems” by Ro Won Myong, a department chief of the Faculty of Applied Mathematics, came second. Most of the proposals entered the rankings.

The 10th Mathematical Modelling Contest of the University was held from April 30 to May 5.
The contest, which drew over 90 students in 31 teams selected from colleges and faculties, took place in the way of examining excellent answers from each unit.
Jong Hyong Il, An Jin Su and Hyon Jin Song from the College of Information Science &Technology won the contest. Jang Kum Chol, Jo Kuk Jin and Kim Ji Hyon from the Faculty of Automation Engineering finished runners-up and Kim Jin Il, Ri Kang Hyok and O Yon A from the Faculty of Applied Mathematics came third.
They owed their success to Jong Myong Guk, lecturer in the Department of Information Processing at the College of Information Science & Technology, Kim Ju Hyong, head of research lab of bio-control engineering of the Faculty of Automation Engineering, and O Chol Won, lecturer in the Deaprtment of Numeral Mathematics at the Faculty of Applied Mathematics, who devoted time and energy to their education.
