Insulating aluminum on the market volume size is very strict, with the same thickness, the manufacturers in the production process is how to ensure the preservation of the aluminum coil with identical thickness? This requires insulation aluminum coil indirect thickness method, including pressure determination and bearing box displacement measurement.
1, pressure measurement method is based on the rolling process, rolling forces to adjust the pressure, the higher the amount of reaction, the greater the pressure, to adjust the system by using the pressure change control of aluminum strip thickness. The deficiency of this approach is: sometimes the incoming uneven thickness or roll eccentricity; the rolling force changes.
When the rolling process of aluminum coil insulation thickness exceeds the allowable deviation, indirect thickness method can quickly in a few milliseconds can be corrected, the insulation thickness deviation of aluminum coil remains within the range of a few microns, consistent insulation aluminum coil specifications.

According to the signal change is difficult to determine the causes of variation in thickness and the regulation measures. Harbin Dong Xing Aluminum Co., Ltd is a competent and reliable Aluminum cladding coil manufacturer china.
2, work roll gap measuring method is the direct determination of two work roll gap variation, this method is generally measured by displacement of the roller bearing box to achieve. Harbin Dong Xing Aluminum Co., Ltd could provide you with Aluminum coating coil on sale.
It can maintain the thickness deviation within 2 micron, the minimum resolution of this system is 1 microns, the stability of the sensor is only 0.1~0.2 seconds this method is the lack of; can not be adjusted due to the elastic work roll caused by the rolling pressure of flattening roll gap change.
It is equipped with pressure gauge, pressure signal according to the determination, determination of the roll gap and roll gap change signal, the two together, can make the determination of roll gap the sensitivity of 1 microns, adjusting the time of just 0.1% seconds.
When the rolling process of aluminum coil insulation thickness exceeds the allowable deviation, indirect thickness method can quickly in a few milliseconds can be corrected, the insulation thickness deviation of aluminum coil remains within the range of a few microns, consistent insulation aluminum coil specifications.
