Problems solved by technology

[0003] However, the price of the existing silicon steel sheet is relatively high, which leads to high manufacturing cost of the motor. If there are other low-priced materials that can replace the silicon steel sheet, the manufacturing cost of the motor will be reduced to a certain extent

Embodiment Construction

[0013] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0014] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

Abstract

The invention discloses a carbon structural steel annealing process. By virtue of continuous twice heating and insulating measures, the heating speed and insulating time can be controlled, so that thecrystal orientation of a punching sheet sheared edge formed in an extruding manner in the punching process is re-disturbed; and the stress inside the material formed by the punching and shearing is eliminated, the burrs are eliminated, and the vortex loss of the punching sheet in the operation of a motor can be further eliminated. Moreover, by virtue of the subsequent rapid cooling for the punching sheet, the component failure caused by the oxidation rustiness of a shear mouth of the punching sheet can be further solved by adopting the anhydrous blueing effect. By adopting the annealed punching sheet obtained according to the process, the iron loss of the punching sheet material can be greatly decreased by 3W / KG or above, a purpose of substituting a silicon steel sheet can be achieved, and the production cost of the motor can be effectively decreased.

Description

technical field [0001] The invention relates to the technical field of motor processing, in particular to an annealing process for carbon structural steel. Background technique [0002] Motor silicon steel sheet refers to non-oriented silicon steel sheet containing less than 2.8% silicon. It has certain mechanical strength and is mainly used to manufacture motors, so it is commonly known as motor silicon steel sheet. [0003] However, the price of the existing silicon steel sheet is relatively high, which leads to high manufacturing cost of the motor. If there are other low-priced materials that can replace the silicon steel sheet, the manufacturing cost of the motor will be reduced to a certain extent. [0004] Ordinary cold-rolled carbon structural steel Q195 has the potential to replace silicon steel sheets to a certain extent, but cold-rolled carbon structural steel will generate stress during the punching and shearing process. How to anneal cold-rolled carbon steel to r...
