1.Material factor
In induced quenching steel, manganese, chromium, and molybdenum content have the greatest effect on the depth fluctuation of the hardensed layer. If the cutting sensor quenching found that the heating layer is similar, the depth of the hardened layer is large, and the material factor should be doubted.
2. Device factor
(1) Power voltage fluctuations and no energy control monitoring can cause quenching temperature fluctuations, it directly affects the quality of the quenching.
(2) The quenching speed fluctuates, the hydraulic quenching machine affects the scanning speed due to oil temperature changes, this problem is no longer generated due to mechanical transmission in modern quenching bed.
(3) Sensor aging and deformation, especially magnetosomensome aging. The magnetosome aging, the sensor efficiency is reduced, directly reducing the quenching temperature, which is a matter of paying attention.
(4) The concentration, pressure, flow and temperature of the quenching medium of the quenching medium will affect the depth of the hardened layer.
