The bending process of bent steel during tempering is a complex and delicate craft that combines multiple steps such as heating, bending, and cooling of the steel. Below is a detailed explanation of the bending process of tempered bent steel:
1. Heating
Purpose of heating: To heat the steel to a certain temperature, softening it and making it plastic, facilitating subsequent bending operations.
Heating method: Typically, a heating furnace is used for uniform heating of the steel, with the heating temperature and time adjusted according to the thickness, material, and required degree of bending of the steel.
Heating temperature: The heating temperature should be controlled above the critical temperature of the steel, but avoid excessive heat that could lead to over-oxidation or deformation of the steel.
2. Bending
Bending method:
For bent steel, specialized bending equipment or molds are usually used for the bending operation.
During the bending process, appropriate pressure must be applied to the steel to bend it according to the predetermined arc.
Bending parameters:
Bending radius: Choose an appropriate bending radius based on the material and thickness of the steel, as well as the required degree of bending.
Bending angle: Determine the bending angle of the steel according to design requirements.
3. Tempering
Purpose of tempering: To change the microstructure of the steel through rapid cooling, improving its hardness, toughness, and wear resistance.
Tempering method:
Quickly place the bent steel into a cooling medium (such as water, oil, or air) for rapid cooling.
The cooling speed and time should be adjusted according to the material of the steel and the required performance.
Tempering effect:
The surface hardness and strength of the steel are improved, and defects are eliminated.
The tensile strength, compressive strength, hardness, and wear resistance of the steel are also enhanced.
4. Precautions
Temperature control: During the heating and cooling processes, temperature must be strictly controlled to avoid cracks or deformation of the steel due to excessively high or low temperatures.
Bending accuracy: During the bending process, it is necessary to ensure that the steel is bent according to the predetermined arc to avoid excessive errors.
Cooling uniformity: During the tempering process, it is essential to ensure that the cooling of the steel is uniform to avoid local hardening or softening.
In summary, the bending process of bent steel during tempering is a complex craft involving multiple steps such as heating, bending, and cooling. By precisely controlling the parameters and conditions of these steps, it is possible to ensure that the bent steel possesses the required performance and quality after tempering.
