Sprockets through the early draft and the design parameters to the latter part of the production and processing is a strict requirement and control, especially in the annealing process, the quality of an annealing directly affect the quality of the sprocket production, annealing process not only in the chain Wheel industry has a wide range of uses, but also in other metal industry has a very high appearance, the following we will introduce the annealing process for the sprocket production role.

Normalizing is the common process for the heat treatment of the sprockets and bearing parts of automotive transmissions. This is done in order to achieve a uniform, Polished. However, the normalizing is restricted by the equipment, so it is forced to adopt the way of stacking and cooling, which will cause different cooling rate of different parts or the same parts, which will result in great difference of organization, stress and hardness. A malicious cycle, the product cutting deformation or increase the size or reduce the size, reducing the accuracy and quality of the product
