| Abstract | The heating process of aluminum billets requires controllable temperature distributions and high efficiency. Compared with conventional ac induction heaters, the high temperature superconductor (HTS) dc induction heater has advantages of energy saving and better heating quality. In this paper, a HTS magnet is designed to achieve controllable temperature distribution for dc induction heater. A C-shaped iron yoke is used to separate HTS coils and billets. An aluminum billet is rotated in the air gap of the C-shaped magnet. Magnetic field distribution can be changed through adjusting width of the air gap. Therefore, the temperature gradient in axial direction is controllable. A dc induction heater prototype using this design is fabricated and its heating characteristics are tested. A numerical model is built to simulate heating process and temperature distributions of aluminum billet. Various uniform and gradient temperature distributions of a billet are measured and compared with numerical results. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
