8011 aluminum foil manufacturer introduces production defects

8011 aluminum foil manufacturer - common problems in aluminum foil production
8011 aluminum foil manufacturer introduced, aluminum foil in the rolling process, due to plastic deformation of the metal, continuously create a new surface, and the contact surface has a high unit pressure, coupled with high deformation temperature, sliding speed and other characteristics, The phenomenon of adhering metal to the surface of the roll and the wear of the roll is particularly prominent.
8011 aluminum foil manufacturer - on rolling wear problems
1. The wear of 8011 aluminum foil during rolling is extremely complicated. Metal wear may be related to factors such as metal materials, surface oxides, work hardening, processing temperature, speed, lubricants and the surrounding environment.
2. During the deformation process of the material, the wear mechanism may be one or several mechanisms acting simultaneously. Moreover, the deformation process itself is also changing.
3. During rolling, the rolls are repeatedly and continuously in contact with the rolled piece, and the surface of the rolled piece entering the deformation zone is constantly changing.
4. In addition, the surface of the workpiece is cleaned by acid pickling. When it comes into contact with the surface of the dirty roll, the plastic deformation and elongation increase the possibility of adhesion and the peeling of the wear point. If the wear point height is greater than the oil film thickness, then The particle will be pressed against the surface to act as a grinding roller surface.
8011 aluminum foil manufacturer - about the type of aluminum foil wear
According to the 8011 aluminum foil manufacturer, the aluminum foil has different wear types due to the contact surface morphology, contact conditions and environmental conditions. However, it can be generally divided into two major types of mechanical wear and chemical wear.
Mechanical wear is a type of wear process associated with friction, abrasive wear, erosion, and fatigue;
Chemical wear is caused by the erosion of various active substances on the surface, which is then caused by mechanical action to cause friction and breakage of these reactants. Different types of wear can occur individually, sequentially or simultaneously. The excessive stress on the worn surface is a common feature of various wear phenomena.
8011 aluminum foil manufacturer Mingtai Aluminum
8011 aluminum foil manufacturer Mingtai Aluminum is one of the top ten enterprises in China with aluminum foil and foil. The top 500 enterprises in China are privately-owned enterprises. The aluminum foil produced has excellent performance, smooth surface, no cracks, corrosion spots and traces of nitrate. It is well received by the market. In the future, we will continue to pay close attention to the quality of aluminum foil products, strive to enhance the influence of corporate brands, enhance customer satisfaction, and create more wealth for customers.
