To improve the high temperature and abrasion resistance of steel sleeve for aluminum foil mill, we can start from the following aspects:

Selection of high quality materials

The choice of material for the steel sleeve is crucial. High-quality materials, such as 35crmo, 35crnimo, 35crmov and other grades of cast steel, have high high temperature resistance and wear resistance. These materials can withstand high temperature and high pressure working environment, reduce the aging and wear of the steel sleeve, so as to extend its service life.

Heat treatment process

Quenching treatment: after heat treatment quenching of steel sleeve, its strength will be significantly improved, and can better resist the huge pressure generated in the rolling process. Quenching treatment can also improve the internal organization of the steel sleeve, improve its resistance to high temperature and wear resistance.

Tempering treatment: Tempering treatment is a combination of quenching and high-temperature tempering process, so that the steel sleeve to obtain good comprehensive mechanical properties. This treatment can further improve the high temperature resistance and wear resistance of the steel sleeve, while maintaining its sufficient plasticity and toughness.

Optimized design

Improve processing accuracy: the design and processing accuracy of the steel sleeve directly affects the degree of matching with the roll and the overall performance of the mill. By improving the machining accuracy, you can ensure that the steel sleeve in the use of the process and the roll of the close match, reduce wear and friction.

Optimization of structural design: reasonable structural design can reduce the steel sleeve in the work of stress concentration and friction loss. For example, streamlined design can be used to reduce fluid resistance, thereby reducing friction and wear.

Care and Maintenance

Regular inspection and cleaning: Regularly inspect the steel sleeve to ensure that its surface is clean and dry. Timely cleaning of impurities and dirt attached to the surface of the steel sleeve can reduce friction and wear.

Lubrication and Cooling: A good lubrication and cooling system reduces the temperature and coefficient of friction of the steel sleeve during operation, thus reducing wear and damage. The use of suitable lubricants and coolants can significantly improve the wear resistance and high temperature resistance of the steel sleeve.

Operating skills and training

Improve operation skills: the skill level of operation and maintenance personnel will also affect the life of the steel sleeve. Skillful operation and maintenance personnel can find and deal with problems in time, to avoid steel sleeve due to excessive wear or damage and early scrap.

Regular training: Operators and maintenance personnel are regularly trained to improve their specialized skills and knowledge. This helps to ensure the correct use and timely maintenance of the steel sleeve and prolong its service life.

In summary, the high temperature and wear resistance of steel sleeves for aluminum foil mills can be significantly improved through the selection of high-quality materials, heat treatment process, optimization of design, maintenance and repair, as well as the improvement of operating skills and training. The implementation of these measures will help to extend the service life of the steel sleeve and improve the production efficiency and product quality of the aluminum foil rolling mill.
