Due to the different conducting frequency induction hardening, the structural stiffness and power requirements of the electrical sensing conductor thickness is more stringent requirements. IF equipment used in electric somatosensory more stringent requirements, the theoretical value requires a wall thickness of 1.02mm . Experience has shown that: wall thickness of 1mm , size of 10mm × 8mm , 16mm × 10mm rectangular tube frequency quenching can meet the requirements, but 1mm thick, 16mm × 10mm rectangular tube structural rigidity difference, short life, easy because magnetizer electrically sense deformation or fracture can not install card, only suitable for use as a small electric sense conductor. Therefore, if it is used in batches or heated in large sections, rectangular tubes with a wall thickness of 1.3 to 1.5 mm should be used . After the thickness of the pipe wall is increased, the processing of the water spray hole should increase the initial " drawing socket " process, otherwise it is very easy to damage the drill bit.
