The speed and quality of aluminum large drawing wire (usually refers to the large drawing process of aluminum wire) are affected by many factors. Here are some of the main factors:
1. Quality of raw materials:
The purity, composition uniformity and impurity content of raw materials will directly affect the performance and final quality of aluminum wire in the drawing process.
2. Drawing mold design:
The material, shape, dimensional accuracy and wear of the mold will affect the drawing speed and the surface quality of the aluminum wire.
Mold taper, inlet and outlet size design is very important to the tensile force and wire diameter control of aluminum wire.
3. Drawing machine equipment performance:
The accuracy, stability, tension control system and cooling system of the wire drawing machine will affect the speed and quality of the wire drawing.
The old and new condition of the equipment and the state of maintenance will also have an impact.
4. Drawing process parameters:
Including drawing speed, drawing ratio, annealing process, etc., the selection of these parameters needs to be determined according to the material and end use of the aluminum wire.
Improper process parameters may lead to aluminum wire breakage, surface scratches or wire diameter inequality.
5. Cooling conditions:
The cooling rate and the type of cooling medium are critical to the temperature and hardness control of the aluminum wire.
Proper cooling can prevent the aluminum wire from overheating or creating internal stress, which affects the speed and quality of the wire.
6. Selection and use of lubricants:
The type, concentration and uniformity of the lubricant affect the friction coefficient between the aluminum wire and the die, which in turn affects the wire drawing speed and the surface quality of the aluminum wire.
7. Environmental factors:
Environmental factors such as temperature, humidity and cleanliness in the workshop will also have an impact on the aluminum wire drawing process.
Too high or too low temperature, humidity fluctuations, or contaminants can adversely affect the quality of the aluminum wire.
8. Skill level of the operator:
The experience, skill and concentration of the operator have a great impact on the stability of the wire drawing process and the final quality of the aluminum wire.
To sum up, the speed and quality of aluminum large drawing wire are affected by many factors. In order to obtain high-quality aluminum wire products, these factors need to be considered comprehensively and optimized.
