Method for Rolling Double Zero Aluminum Foil in 1850mm Width Rolling Mill

Abstract

The invention discloses a method for rolling a double-zero aluminum foil through a 1850mm-width rolling mill, and belongs to the technical field of aluminum foil machining. The method comprises the following step of carrying out three-pass rough rolling, one-pass intermediate rolling and one-pass finish rolling on a cast-rolled blank or a hot-rolled blank of which the thickness is 0.3mm on the 1850mm-width rolling mill to prepare the aluminum foil of which the thickness is 0.006-0.009mm and the width is 1,000-1650mm, wherein the roll diameter of a working roll of the rolling mill is phi260mm, 90# rolling oil is selected in the rough rolling procedure and the intermediate rolling procedure; 82# rolling oil is selected in the finish rolling procedure; an alcohol additive and / or ester additive is selected as the additive; and the rolling oil has the specifications after being prepared by using the additive at 40 DEG C as follows: the viscosity is 1.9-2.5mm<2> / s, the flash point is 80-95 DEG C, the distillation range is 205-260 DEG C, the hydroxyl value is 4-12mgKOH / g and the saponification value is 10-18MgKOH / g. The produced product is stable in quality and high in yield.

Description

technical field [0001] The invention relates to an aluminum foil rolling method, in particular to a rolling method for producing double-zero aluminum foil with a 1850mm width rolling mill, and belongs to the technical field of aluminum foil processing. Background technique [0002] Aluminum foil is a thin sheet directly calendered by metal aluminum, usually refers to a thin strip with a thickness less than or equal to 0.2mm, and is often used as hot stamping materials, capacitors, packaging materials, etc. At present, countries have different regulations on the thickness of aluminum foil. China, France, Russia, etc. define the upper limit of the thickness of aluminum foil as 0.2mm; the United States, the United Kingdom, Japan, etc. define the upper limit of the thickness of aluminum foil as 0.15mm; The upper limit is defined as 0.02mm. [0003] In China, the thickness is usually less than 0.01mm, that is, the foil with two zeros after the decimal point is called double zero...

Problems solved by technology

Moreover, as the thickness of the aluminum foil decreases, the size, shape and distribution of the compound in the aluminum foil will have a great impact on the number of pinholes in the aluminum foil, thus damaging the ductility of the aluminum foil and deteriorating its mechanical properties.
