Problems solved by technology

Abnormalities such as air holes and impurities have occurred many times in the daily use of aluminum rods in most companies, especially in fine production, which has led to a significant increase in production costs.
At the same time, in the cooling and winding process of the aluminum rod, the existing equipment is often prone to intertwining when performing multi-strand winding. At the same time, it is inconvenient to guide the aluminum rod into the water tank for cooling during cooling.

Abstract

The invention discloses an electrical aluminum alloy round bar for an aluminum-based electromagnetic wire and a production process of the electrical aluminum alloy round bar. The production process utilizes the special structure and physicochemical properties of rare earth elements, La, Ce and hydrogen in molten aluminum have strong attraction, and a stable high-melting-point compound can be formed, so that the hydrogen in the aluminum melt is fixed and removed, air holes are reduced to the greatest extent, impurities in the furnace can be effectively removed through high-temperature salt formed by rare earth elements in the smelting furnace, a cooling and winding mechanism conducts pressing treatment on the electrical aluminum alloy round bar for the aluminum-based electromagnetic wire before cooling and winding, and certain pressing force is applied to the electrical aluminum alloy round bar for the aluminum-based electromagnetic wire, so that the situation that multiple strands of electrical aluminum alloy round bars for the aluminum-based electromagnetic wire are intertwined before being wound is effectively prevented, it is guaranteed that the electrical aluminum alloy round bars for the aluminum-based electromagnetic wire can be evenly wound on an installation sleeve in the winding process, and the wound electrical aluminum alloy round bars for the aluminum-based electromagnetic wire can be taken out conveniently.

Description

technical field [0001] The invention relates to the technical field of enameled wire production, in particular to an electrical aluminum alloy round rod for aluminum-based electromagnetic wire and a production process thereof. Background technique [0002] The main raw materials in the production of enameled wire are insulating varnish and aluminum. The influence of insulating varnish on enameled wire is self-evident, and varnish affects the performance of all aspects of enameled wire. With the enameled wire entering the integrated processing mode, in recent years, various enameled wire manufacturers have put the quality of aluminum on the agenda. Good aluminum not only has good and stable electrical conductivity, but also has a low rate of wire breakage in wire drawing and enameled production. Abnormalities such as pores and impurities have appeared many times in the daily use of aluminum rods in most companies during wire drawing and enamelling, especially in fine produc...
