The cross-sectional shape of the induction coil of the induction heating furnace

The induction coil of the induction heating furnace has many cross-sectional shapes, such as round, square, rectangular, plate type (outer welding cooling water pipe), etc. When the quenching area is the same, the rectangular cross-section induction coil is the most material-saving, and the heating layer Uniform, circular section is the worst, but easy to bend. The materials used are mostly brass tubes or copper tubes, the wall thickness of the high frequency induction coil is 0.5mm, and the intermediate frequency induction coil is 1.5mm.
