Single-turn induction heating coil

摘要

PPROBLEM TO BE SOLVED: To provide a single-turn induction heating coil in which reduction of facility cost can be realized, even if the effective heating length is long to reduce the heating speed, and maintenance and inspection of the coil are easy, and which can heat the steel belt to a Curie-point or higher. PSOLUTION: This is a single-turn induction heating coil that comprises a first conductor part on the top face side and a second conductor part on the bottom face side which extend in the width direction of the metal belt plate having a prescribed space between the metal belt plate and the top face and the bottom face of the metal belt plate and, of which both ends are located on the outside of the both ends of the metal belt plate, and a third conductor part which extends in the thickness direction of the metal belt plate on the outside of the side end in the width direction of the metal belt plate and connects each one end of the above first conductor part and the second conductor part. The first conductor part and the second conductor part are respectively increased by one piece (two pieces or more) and each open end of the two pieces of (three pieces or more) the first conductor part and the second conductor part are connected to the fourth conductor part extending in the longitudinal direction of the metal belt plate. And the first conductor part and the second conductor part are installed in the position mutually shifted in the longitudinal direction of the metal belt plate. PCOPYRIGHT: (C)2003,JPO
