Aluminium cold rolling process is an important metal processing process, which can process aluminum sheet into products of various shapes and sizes, which are widely used in aviation, automobile, construction and other fields. This article will introduce the basic process and key technologies of the aluminum cold rolling process.
The basic process of aluminium cold rolling process includes: raw material preparation, hot rolling, pickling, cold rolling, annealing, cutting and packaging. Among them, cold rolling is the core link of the whole process, which makes the aluminum sheet reach the required thickness and hardness through multiple rolling and stretching. In the cold rolling process, parameters such as rolling force, rolling speed, and rolling temperature need to be controlled to ensure the quality and performance of the cold rolled aluminum sheet product.
The key technologies of the aluminum cold rolling process include: selection and adjustment of rolling machinery, design and manufacture of rolling rolls, selection and use of rolling lubricants, temperature control and surface treatment during rolling, etc. Among them, the selection and adjustment of rolling machinery is the basis of cold rolling process, and different rolling machinery is suitable for different thickness and hardness of aluminum sheet. The design and manufacture of rolling rolls is the key to ensure product quality, it needs to consider the material, shape, size and other factors of the roll. The selection and use of rolling lubricants can reduce rolling force and friction, improve rolling efficiency and product surface quality. Temperature control and surface treatment during rolling can affect properties such as hardness, strength, and surface finish of the product.
The aluminium cold rolling process is a complex processing process, which needs to master a variety of technologies and process parameters to ensure the quality and performance of the product. With the continuous advancement of science and technology and continuous improvement of technology, the production process of aluminum cold rolling will be more efficient, precise and environmentally friendly, providing better support and guarantee for the development of various fields.
