Common quality problems solution of aluminum alloy coils

In the production process of alloy aluminum coil, quality problems are easy to occur due to equipment or personnel operation errors, etc. The common quality problems of alloy 1060 O transformer aluminum coil are summarized as follows, and it is hoped that the production department can pay attention to this problem.

1. Oil stain is common in quality problems: oil stain refers to excessive oil on the surface of aluminum tip after rolling, and it carries excess oil except rolling oil film, which is visible to the naked eye during slitting production and finished product inspection. The surface is oily. These oils are mainly caused by the top of the roll neck or the exit of the rolling mill, the smashing, splashing, dripping on the box surface and the abnormality of the rolling mill roller, the dripping of the rolling mill, and often the dirty components. complex.

2. This oil will bring harm to the surface of the H temper transformer aluminum coil: First, because most of the aluminum coil products as a decorative or packaging material, must have a clean surface; second, its thickness is thin, easy to form bubbles in the subsequent annealing Shape, and because of the large amount of oil in the formation of excessive residue and affect the use. Oil defect is a very important indicator for evaluating the quality of factory price thickness aluminum coil.

3. Solution: Strictly check the production equipment before production. If it is found that the oil in the equipment is too much, it should be cleaned in time and find the cause. At the same time, the surface of the production product should be cleaned and processed. If the product cannot be cleaned, it will be treated with oil. Products are prohibited from entering the warehouse and entering the market.

4. Scratch is a frequent customer of quality problems: scratches and bumps are intermittent or continuous surface of the aluminum coil. Generally, the sharp object is produced when the surface of transformer aluminum coil is relatively slipped after contact with the surface of the foil.

5, the main reason: the roll, the surface of the guide roller has a pointed defect, or stuck with hard debris; shearing, winding, slitting mechanical guide roller, guide path with pointed defects or dry debris. Injury: A bundle (or group) distribution of scars on the surface of a box due to relative sliding or misalignment between the objects and the surface or surface.

For these details, we must pay attention to it. Otherwise, these common quality problems of alloy aluminum coils will seriously affect our future use, so everyone will avoid the troubles in the future and solve these problems once in production.
