Cooling method of angle beam extrusion production line

Cooling method and product quality in angle beam extrusion production line
In the corner beam extrusion production line, the cooling link plays a vital role. It is not only directly related to the final quality of the product, but also affects production efficiency and cost control. The selection and control of cooling methods, as the core elements of this link, have a far-reaching impact on product quality.
1. Selection of cooling method
In the production of angle beam extrusion, the cooling methods are mainly divided into air cooling and water cooling. These two cooling methods have their own advantages and disadvantages and are suitable for different production scenarios and product requirements.
Air cooling: The air cooling method mainly cools the extruded angle beam through the airflow generated by the fan or blower. This method has the advantages of simple equipment, easy maintenance, and uniform cooling. However, the air cooling method is greatly affected by the ambient temperature and air flow speed, which may lead to insufficient cooling speed or uneven cooling, thus affecting product quality.
Water cooling: The water cooling method directly cools the extruded angle beam through water or aqueous solution. This method has a fast cooling speed and can quickly take away heat, which is conducive to maintaining the shape and dimensional stability of the product. However, water cooling also has disadvantages such as complex equipment, high maintenance costs, and the possibility of introducing moisture to cause product corrosion or deterioration.
2. The impact of cooling methods on product quality
The choice of cooling method has a direct impact on the quality of angle beam extrusion products. A reasonable cooling method can ensure that the product cools down and solidifies quickly after extrusion, thereby maintaining the stability of its shape and size. Specifically, the impact of cooling methods is mainly reflected in the following aspects:
Dimensional stability: Too fast or too slow cooling speed may cause fluctuations in product size. A reasonable cooling method can ensure that the product maintains a stable size during the cooling process, thereby improving the product's qualified rate.
Surface quality: Uneven cooling may cause defects such as cracks and deformation on the surface of the product. Using appropriate cooling methods, such as air cooling combined with appropriate wind speed and wind direction, or water cooling combined with appropriate water temperature and water flow rate, can significantly improve the surface quality of the product.
Internal organization: The cooling method also affects the internal organizational structure of the product. A reasonable cooling rate helps to form a uniform and dense internal organization, thereby improving the mechanical properties and corrosion resistance of the product.
3. Suggestions for optimizing cooling methods
In order to improve the quality of angle beam extrusion products, the cooling methods can be optimized from the following aspects:
Choose cooling methods according to product characteristics: For different types of angle beam products, appropriate cooling methods should be selected according to their material, shape, size and other characteristics. For example, for large, thick-walled angle beam products, water cooling can be used to increase the cooling speed; while for small, thin-walled angle beam products, air cooling can be used to avoid deformation caused by too fast cooling.
Strengthen the maintenance and care of cooling equipment: Regularly maintain and care for cooling equipment to ensure its normal operation and good condition. For example, regularly clean dust and debris in air cooling equipment, and check whether water pumps, water pipes and other components in water cooling equipment are intact.
Adopt advanced cooling technology: With the continuous development of science and technology, more and more advanced cooling technologies are being applied to angle beam extrusion production lines. For example, the use of new cooling methods such as spray cooling and gas-liquid mixed cooling can further improve cooling efficiency and product quality.
