High Temperature Superconducting Magnets (HTS Magnets)
Dexing Magnet designs and manufactures high-performance high-temperature superconducting (HTS) magnets that deliver exceptional power and efficiency. These advanced magnets operate at 77K using liquid nitrogen, offering a more cost-effective alternative to traditional liquid helium-based systems. Their minimal energy loss, stable high-strength magnetic fields, and compact designs make them ideal for a wide range of industrial and scientific applications.
What Is a Superconducting Magnet?
A superconducting magnet is a special type of electromagnet constructed from Type-II superconductors that exhibit zero electrical resistance and no magnetic core losses under cryogenic conditions. These magnets are capable of generating strong, stable magnetic fields far exceeding what conventional electromagnets or permanent magnets can achieve.
Unlike traditional systems that suffer from resistive heating, superconducting magnets eliminate energy losses, making them highly efficient. They are essential in applications like maglev trains, particle accelerators, and MRI machines, where high field strength and stability are crucial.
Product introduction
Superconducting magnet refers to a type of electromagnet made of a second type superconductor with a high transition temperature and a particularly high critical magnetic field at low temperatures. Its main feature is the absence of electrical losses caused by wire resistance and magnetic losses caused by the presence of iron cores, making it highly practical. It is widely used in industry and scientific research, but it must operate at liquid helium temperature, which is costly.
Superconducting magnets refer to the collective term for superconducting coils and their low-temperature containers. Superconducting magnets are the most important core components of superconducting levitation railways, and the propulsion, suspension, and guidance forces of vehicles are generated by superconducting coils. Like permanent magnets, superconducting magnets can provide a stable magnetic field, and they can also provide a high-strength magnetic field that ordinary permanent magnets cannot provide. This is also the reason why maglev railways use superconducting magnets.
Superconducting magnets for accelerators
Dexinmag company has successively provided ECR superconducting ion source magnets, superconducting dipole magnets (Helmholtz and oblique solenoid type) and linear accelerator focusing Leading solenoids, and at the same time provided focusing superconducting drop-line magnets and superconducting dipole magnets for the Rare Isotope Beam Facility (FRIB) in the United States.
Electron Cyclotron Resonance Ion Source
It is the most effective device to generate a stable and intense beam of multi-charged ions.
Xiamen dexing Magnetic Tech Co., Ltd. has completed the first electron cyclotron resonance ion source magnet in my country, which has excellent performance and filled the domestic gap.
Accelerator Driven Sub-critical System ADS (Accelerator Driven Sub-critical System) has very broad prospects in dealing with nuclear waste and improving fuel utilization.
Our company produced and delivered dozens of focused superconducting magnets for nuclear waste treatment, and realized the standardization of mass production of ADS magnets by controlling product quality, product appearance treatment, packaging and other links;
At present, the manufacture of nearly 20 magnets has been completed, and it will enter the batch preparation stage in 2021-2022.
High Temperature Superconducting Magnet
In recent years, with the development of high-temperature superconducting materials, high-temperature superconducting magnets have gradually entered people's field of vision. Due to its unique operating temperature (77K in the liquid nitrogen zone) and the relatively cheap advantages of liquid nitrogen, high-temperature superconducting magnets have become a magnet for scientific research institutes of various enterprises. research hotspots;
Our company has completed the research and development of high-temperature superconducting magnets for superconducting current limiters with the world's largest voltage level (500KV). ;
The successful completion of the project indicates that the company has fully mastered the processing of the first-generation and second-generation high-temperature superconducting coils, and has accumulated experience for the development of other high-temperature superconducting products.
High Temperature Superconducting Magnets For Induction Heating
The limitations of the existing AC induction heating technology: skin effect, resulting in a small heat penetration depth of the heated metal rod, low heating uniformity, and low heating efficiency;
The superconducting induction heating technology generates a background magnetic field through a superconducting magnet, establishes a DC air gap magnetic field in the heating area, and the billet is heated by rotating and cutting the magnetic force line to generate eddy currents;
In this way, a heating method with high penetration depth, high energy efficiency, high heating uniformity, and controllable temperature gradient can be realized, which can ensure the high added value of the quality of the processed workpiece.
