After high-frequency quenching, the carbon content of the gear will be higher and higher. After annealing, the hardness is many times higher than before, which is beneficial to the processing performance of the product. Next, Kehua Induction Heating Equipment
will tell you how to calculate the price of high-frequency quenching of gears. The price of high-frequency quenching of gears 1. Working principle of high-frequency quenching Into the inductor, the inductor is generally a hollow copper tube that inputs intermediate frequency or high frequency alternating current (1000-300000Hz or higher). The alternating magnetic field generates an induced current of the same frequency in the workpiece. The distribution of this induced current in the workpiece is uneven, it is strong on the surface, but weak in the interior, and it is close to 0 in the center. This skin effect is used. , the surface of the workpiece can be heated rapidly, and the surface temperature rises to 800-1000ºC in a few seconds, while the temperature of the core rises very little. Second, the advantages of gear high-frequency quenching Normalizing after forging is a pure process. If the carbon content or alloying elements are high, additional tempering can be added. The post-forging heat treatment refers to the heat treatment set to eliminate the defects generated in the forging process or to make other processes after forging go well, such as normalizing, annealing, etc. It is used to eliminate the forging stress and uniform the structure. Annealing reduces hardness and facilitates subsequent machining. 3. Gear high frequency quenching processing price 1. The listed price is the price of a single piece weighing more than 0.5kg. If the single piece weight is less than or equal to 0.05~0.25kg, the price will be increased by 20% according to the listed price. 2. The price of the straightened parts is increased on the basis of the price of the heat treatment process. The price of low-hardness parts is increased by 30%, the price of medium-hardness parts is increased by 50%, and the price of high-hardness parts is increased by 80% (both including stress relief and tempering). mutually agreed. 3. Direct quenching after carburizing, the quenching processing fee is calculated at 50% of the quenching price. 4. Calculation of the weight of high and medium frequency surface quenched parts: Gear high frequency quenching processing price After the gear is quenched by high frequency, the density becomes higher, the hardness also increases, and it is widely used in various industries.
