China's first low-temperature superconducting iron remover developed

Nov 06, 2008     Email"> PrintText Size


In cooperation with engineers from Shandong Huate Magnet Technology Co., Ltd, scientists and technicians from the CAS Institute of High Energy Physics (IHEP) have developed China's first low-temperature superconducting iron remover, a major piece of equipment for separating the ferromagnetic matter from coal and other raw materials.

The low-temperature superconducting magnet, the key component of the facility, is the brainchild of IHEP researchers, thanks to their two-year efforts to put into practical application their know-how on superconducting technologies derived from the Beijing Spectrometer,

With a large diameter of 0.93 meter, the magnet has an energy storage capacity up to 3.4 megajoules and its highest magnetic field intensity could reach as much as 56,000 gausses. Under the superconducting state (at minus 269 degrees centigrade), its coil is resistance-free, which allows the passing through of a high current and the formation of a super intensified magnetic field. The iron separator produced with the technology is noted for a very strong iron absorption capacity, low weight, energy efficiency and environment friendliness. And it costs only 60% of the prices of similar facilities from US.

CAS Institutes

There are 124 Institutions directly under the CAS by the end of 2012, with 104 research institutes, five universities & supporting organizations, 12 management organizations that consist of the headquarters and branches, and three other units. Moreover, there are 25 legal entities affiliated and 22 CAS invested holding enterprises...
