Researchers of the Hi-tech Products Company under Pyongyang University of Mechanical Engineering manufactured a cast iron analyzer needed in the metallurgical industry sector.
The device can promptly measure in front of the furnace the amount of components of molten iron during the melting process and, according to the results, automatically indicate the amount of necessary supplementary ingredients and estimate the spheroidizing rate of graphite.
For the few analytical error, it makes it possible to correctly appraise the quality of cast-iron products for various purposes.
It takes less than two minutes to analyze the products.
It is paying off in several units, including the Haeju Tractor Parts Factory.
