How to design the cooling water circuit and water spray hole of the kulîlk

Considering that the induction heating furnace generates heat due to eddy current loss, each component needs to be cooled by water. For the coil copper tube, it can be directly cooled by water, and the copper plate manufacturing part can be made into a sandwich or externally welded copper tube to form a cooling water circuit; intermediate frequency continuous or simultaneous When self-spray cooling is used for heating, the diameter of the water spray holes of the induction coil is mostly 0.8~1.0mm, and the intermediate frequency heating is 1~2mm; the angle of the water spray holes of the continuous heating and quenching induction coil is 35°~45°, and the hole spacing is 3 ~5mm. At the same time, the heating and quenching water spray holes should be staggered, and the hole spacing should be uniform. Generally, the total area of the water spray holes should be smaller than the area of the water inlet pipe to ensure that the water spray pressure and the water inlet pressure meet the requirements.
