the characteristics of wear in the production of aluminum foil

Date: 2019-07-17 17:01
Aluminum foil in the production and rolling process will inevitably have a certain degree of wear, after research we found that aluminum foil wear has certain characteristics, a simple analysis for you.

In the rolling process of aluminum foil, due to the plastic deformation of metal, new surface is continuously generated, and the contact surface has a high unit pressure, coupled with the high deformation temperature, sliding speed and other characteristics, so that the roller surface adhesion to metal, roller wear and other phenomena are particularly prominent. When the metal is adhered to the roller, the sliding external friction between the two will turn into the internal friction of the metal surface, and the shear deformation of the subsurface will occur, so as to change the friction state at the adhesion site of the metal, leading to the change of the metal stress state and the change of the flow state. As a result, the friction increases, the energy consumption increases, the surface of the product is damaged significantly, the roller wears sharply, and the service life is shortened.

The wear condition in rolling process of aluminum foil  is very complicated, metal wear is related to metal material, surface oxide, work hardening, processing temperature, speed, lubricant and surrounding environment. In the process of material deformation, one or more mechanisms may play a role simultaneously. Moreover, the deformation process itself is variable. When rolling, the roll is repeatedly and continuously in contact with the rolled piece, and the rolled piece into the deformation area of the surface is constantly changing. In addition, the surface of the workpiece is cleaned after pickling, and when it comes in contact with the dirty roller surface, plastic deformation and extension aggravate the possibility of adhesion and peeling of the worn particle. If the height of the worn particle is greater than the thickness of the oil film, then the particle will be pressed onto the surface, playing the role of grinding roller surface.

Due to different contact surface topography, contact conditions and environmental conditions, the wear types of aluminum foil are different. However, it can be divided into mechanical wear and chemical wear. Mechanical wear is a kind of wear process related to friction, abrasive wear, erosion and fatigue. Chemical wear is caused by the erosion of the surface by various active substances, followed by the friction and breakage of these reactants caused by mechanical action. Different types of wear can occur independently, sequentially, or simultaneously. High stress on the worn surface is the common characteristic of various wear phenomena.

Henan mingtai is China's top ten aluminum foil manufacturers, can undertake 3-2000 tons of aluminum foil raw material orders, product quality is stable, global export, affordable price, can rest assured purchase!
