Embodiment

[0021] The invention provides a surface treatment process for an aluminum rod, comprising the following steps:

[0022] Step 1, lye preparation: put 500kg of industrial caustic soda (20 bags, 25 kg / bag) into the alkali pool, and then inject clear water (tap water) to prepare lye, which is sodium hydroxide aqueous solution with a concentration of 3-5%. The temperature of the lye is controlled at 20~25°C.

[0023] Step 2. Alkaline cleaning: Remove the identification plate on the aluminum rod, and divide each coil of material produced by continuous casting and rolling. Each coil of rod material is divided into two small plates, and the material distribution should be uniform. Use a steel pole with a hook and a crane to hang the divided rod material into the alkali pool prepared with lye, and let the lye fully submerge the aluminum rod, and shake it up and down repeatedly 2 to 3 times to make the aluminum rod in the lye Fully react, the time of alkali cleaning is controlled withi...

Abstract

The invention discloses a surface treatment process for aluminum rods. The surface treatment process includes the specific steps of firstly, preparation of alkali liquor, wherein industrial caustic soda is put in an alkali pond, and the alkali liquor is prepared; secondly, alkali washing, wherein the to-be-washed aluminum rods are hoisted into the prepared alkali liquor through a crane, and the aluminum rods are fully submerged in the alkali liquor; thirdly, rinsing, wherein after alkali washing is completed, the aluminum rods are transferred into a rinsing pond; fourthly, washing, wherein after rinsing is completed, the aluminum rods are hoisted out of the water surface, and the interiors and the exteriors of the aluminum rods are repeatedly washed through a high-pressure tap water gun; fifthly, detection, wherein after washing is completed, the pH values of residual water of the aluminum rods are detected through pH test paper, the aluminum rods with the pH values ranging from 6.5 to 7.5 are qualified, and the disqualified aluminum rods are washed again; and sixthly, drying, wherein the aluminum rods detected to be qualified are stacked on a designated drying rack, and water is blown away through exhaust fans. The treated aluminum rods are good in cleanliness, product quality is stable, and it is guaranteed that following aluminum rod processed products have good consistency.

Description

technical field [0001] The invention belongs to the technical field of aluminum material processing, and in particular relates to a surface treatment process of an aluminum rod. Background technique [0002] Aluminum rods are mainly used to process wires and cables. They are drawn into single wires of different diameters by wire drawing, and then twisted into cable conductors. The aluminum rod is made by melting the aluminum ingot, and then the aluminum liquid flows out in a certain direction, and is directly solidified into an aluminum rod. Generally, the diameter of the aluminum rod is about 8mm. [0003] In order to facilitate the subsequent processing of the aluminum rod, the aluminum rod needs to be washed with alkali before processing to remove the dirt and oil on the surface of the aluminum rod. And because a layer of oxide film will naturally form on the surface of the aluminum rod, the combination of the aluminum rod and the solder paste is not good. During alkalin...
