Embodiment 1

[0040] A method for prolonging the rolling oil filtration cycle during aluminum foil rolling, the specific steps are as follows:

[0041] (1) First, evenly coat a layer of clean rolling oil on the bottom surface of the mixing tank with a height of 70mm, and then fill it with a mixture of diatomaceous earth and clean rolling oil to form a pre-coating layer with a thickness of 5mm;

[0042] (2) then fill the premix on the surface of the precoat to form a filter layer with a thickness of 17mm;

[0043] (3) then fill the cellulose on the surface of the filter layer until the total thickness of the filling in the stirring box is 25mm;

[0044](4) Inject polluted rolling oil from the top of the stirring box at last, and the clean rolling oil after filtering flows out and collects from the bottom of the stirring box;

[0045] Wherein, the premix is ​​obtained by uniformly mixing the following components: 10 kg of diatomaceous earth, 7 kg of cellulose, 3 kg of nano-modified polyether...

Embodiment 2

[0066] A method for prolonging the rolling oil filtration cycle during aluminum foil rolling, the specific steps are as follows:

[0067] (1) First, evenly coat a layer of clean rolling oil on the inner bottom of the mixing tank with a height of 80mm, and then fill it with a mixture of diatomaceous earth and clean rolling oil to form a pre-coating layer with a thickness of 2mm;

[0068] (2) then fill the premix on the surface of the precoat to form a filter layer with a thickness of 19mm;

[0069] (3) then fill the cellulose on the surface of the filter layer until the total thickness of the filling in the stirring box is 25mm;

[0070] (4) Inject polluted rolling oil from the top of the stirring box at last, and the clean rolling oil after filtering flows out and collects from the bottom of the stirring box;

[0071] Wherein, the premix is ​​obtained by uniformly mixing the following components: 10 kg of diatomaceous earth, 5 kg of cellulose, 4 kg of nano-modified polyethers...

Embodiment 3

[0092] A method for prolonging the rolling oil filtration cycle during aluminum foil rolling, the specific steps are as follows:

[0093] (1) First, evenly coat a layer of clean rolling oil on the bottom surface of the mixing tank with a height of 75mm, and then fill it with a mixture of diatomaceous earth and clean rolling oil to form a pre-coating layer with a thickness of 3mm;

[0094] (2) then fill the premix on the surface of the precoat to form a filter layer with a thickness of 18mm;

[0095] (3) then fill the cellulose on the surface of the filter layer until the total thickness of the filling in the stirring box is 25mm;

[0096] (4) Inject polluted rolling oil from the top of the stirring box at last, and the clean rolling oil after filtering flows out and collects from the bottom of the stirring box;

[0097] Wherein, the premix is ​​obtained by uniformly mixing the following components: 10kg of diatomaceous earth, 6kg of cellulose, 3.5kg of nano-modified polyether...

Abstract

The invention discloses a method for prolonging a rolling oil filtering period in an aluminum foil rolling process. The method comprises the following steps of: uniformly coating the bottom of a stirring box with a layer of clean rolling oil, and then filling with a mixture of diatomite and clean rolling oil to form a pre-coating layer; filling the surface of the pre-coating layer with a premix to form a filtering layer; filling the surface of the filtering layer with cellulose; and injecting polluted rolling oil from the top of the stirring box, flowing out the filtered clean rolling oil from the bottom of the stirring box, and collecting. By means of the method, the rolling oil filtering period in the aluminum foil rolling process can be effectively prolonged, and the method is environmentally friendly and good in filtering effect.

Description

technical field [0001] The invention relates to a rolling oil filtering method, in particular to a method for prolonging the rolling oil filtering period during aluminum foil rolling. The invention belongs to the technical field of aluminum foil rolling. Background technique [0002] The rolling oil used in the rolling process of aluminum foil will form an oil film on the surface of the rolled piece, which can reduce the friction coefficient and friction force on the contact arc surface of the deformation zone, and ensure the stability of the rolling process; the rolling oil used It is recycled in the rolling process. At present, the filtering process of rolling oil is made of diatomite plus white clay. This filtering method has the problems of short filtering period and low filtering accuracy. [0003] Among them, the cleanliness of rolling oil is an important factor affecting the quality and production efficiency of aluminum foil. Rolling oil with low cleanliness will ea...
