Aluminum-silicon alloy wire forming technology

Abstract

The invention discloses an aluminum-silicon alloy wire forming technology. The aluminum-silicon alloy wire forming technology comprises the steps of first, smelting molding; second, hot extrusion; third, primary softening; fourth, primary wiredrawing; fifth, washing; sixth, second time of softening; seventh, second time of wiredrawing, wherein an aluminum wire which is subjected to the second timeof softening and is with the diameter ranging from 12 millimeters to 14 millimeters is drawn for multiple times to form an aluminum wire with the diameter ranging from 2 millimeters to 2.5 millimeters; and eighth, washing treatment, wherein the aluminum wire with the diameter ranging from 2 millimeters to 2.5 millimeters is placed into an oxidation tank for 2 minutes to 5 minutes, is washed withclear water after being fished out, then is placed into an acid tank for 2 minutes to 5 minutes, is washed with clear water after being fished out, and is finally placed into a dryer to be dried. Because of a specific formula ratio, and specific control over treatment technological parameters such as temperature, time and number of times of softening, wiredrawing diameter change requirements and the step of polishing treatment, an obtained final product is ideal in mechanical performance, is obviously increased in density compared with products of the same type, and is without bubbles, and loss can be reduced in the using process of the product; and polishing treatment can meet requirements without oxidization, and not only is the cost is greatly reduced, but also no environmental pollution is caused.

Description

technical field [0001] The invention relates to an aluminum-silicon alloy wire forming process. Background technique [0002] Aluminum welding wire is also called aluminum flux-cored welding wire, so it is named after this kind of welding wire can weld aluminum and aluminum. It is different from ordinary aluminum welding wire that needs to be welded with argon arc welding machine, and is also different from aluminum-silicon welding wire 4047 that needs to be welded with flux, but can be directly brazed and welded only by flame or induction (because it comes with flux, so no need plus flux). [0003] The existing aluminum wire with a diameter of 2.4mm sold in the market is prone to tiny air bubbles inside the aluminum wire. In the welding of the same area, the loss is relatively large. In addition, the aluminum welding wire of similar products needs to undergo Oxidation treatment, the oxidation cost is relatively high, and the environmental pollution of oxidation treatment ...
