As the society's demand for aluminum foil continues to increase, and it cannot be separated from the aluminum foil rolling mill, the staff must understand the working principle of the aluminum foil rolling mill. When a mechanical failure occurs in the aluminum foil rolling mill, it is necessary to determine the cause of the failure in time to ensure that the aluminum foil rolling mill returns to normal as soon as possible.
When producing aluminum foil paper roll, negative roll gap rolling is used, which is different from other aluminum coil production methods. Usually ordinary aluminum coils have a certain amount of roll gap during production, while aluminum foil rolling mainly relies on two work rolls.
The two work rolls will produce a certain force on the aluminum foil, causing it to elastically deform, and the rolling force exerted by the frame is also greater than the deformation resistance of the metal, which reduces the impact of the rolling force on the thickness of the aluminum foil. At this time, the thickness of the aluminum foil is mainly controlled by olling speed and uncoiling tension.
Aluminum foil is special and has high requirements for raw materials, and it is easy to break during production. Usually the thickness of the aluminum foil is only 0.1~0.2mm, and it needs to be continuously squeezed together by the work roller.
Generally speaking, the aluminum foil rolling mill mainly consists of five parts, namely, uncoiler, coiler, working base, transmission system, ancillary equipment, etc. Among them, the structure of the working machine base and ancillary equipment is relatively complex, and the most critical thing is the control system. Without a complete electrical control system, the thickness of the aluminum foil cannot be guaranteed. This is very important for producing light gauge foil like 30 micron aluminum foil.
Aluminum foil rolling mills are usually divided according to the roll width and are divided into small rolling mills, medium rolling mills, large or wide rolling mills, etc. The width of small mills is less than or equal to 1200mm, while the width of medium-sized mills is between 1200mm and 1800mm, and those with a width greater than or equal to 1800mm are large or wide mills.
The rolling speed required for each specification of rolling mill during production is different. Usually a rolling speed of 1200m/min is called a high-speed rolling mill. The speed will directly affect the production efficiency of the aluminum foil rolling mill. Haomei Aluminum is a big aluminum foil manufacturer.
