A 1-MW industrial-scale high-temperature superconductor (HTS) dc induction heater is being designed and manufactured in Shanghai Jiao Tong University, China. This paper to present the design engineering analysis of a HTS magnet with iron yoke for this heater. generate 0.5-T magnetic field iron's air gap, where billet rotated. To enhance thermal stability, no-insulation (NI) coil metallic insulation (MI) (co-wind stainless steel strips) introduced magnet. The influence NI&MI technique on...
The efficiency of novel superconducting direct current (DC) induction heaters can be up to 80-90%. This is much higher than the 40-50% conventional alternating heaters. Induction are used preheat aluminum billets in extrusion pressing. Such devices use a driving motor rotate billet. A peak electromagnetic torque appears at low rotation speeds (of motor). Therefore, this particular interest when designing system, which one main challenges for megawatt-class DC In paper, characteristics...
Purpose – The purpose of this paper is to analyse and improve the temperature uniformity aluminium billets heated by superconducting DC induction heaters. Design/methodology/approach A 3D electromagnetic model coupled with a heat transfer developed calculate heating process which are rotated in uniform transverse magnetic field. laboratory-scale heater prototype has been built validate model. results from simulation measurement have good agreement. used investigate factors affecting billets....
This paper presents a study on the coil voltage of no-insulation (NI) high-temperature superconductor (HTS) pancake coils during fast discharging operations. Fast tests are performed both double (DP) and an single (SP) NI coil. The measured voltages compared with that from equivalent circuit model, which has been widely used in previous studies. A pulse is observed at beginning fast-discharging operation. It much higher than modeling. peak value increases linearly initial current. Comparison...
Purpose The purpose of this paper is to propose a hybrid driving system that couples motor and flywheel energy storage (FES) for megawatt-scale superconducting direct current (DC) induction heater. Previous studies have proven DC heater has great advantages in relation its efficiency heating quality. In heater, rotates an aluminium billet magnetic field the induced eddy causes it be heated. When begins rotate, high peak load torque appears at low rotation speed. Therefore, economically been...
