Problems solved by technology

Because 6063 has good extrusion performance, it is usually the first choice for extrusion profiles; however, the surface quality and mechanical properties of 6063 alloy after extrusion are average, and it is difficult to meet the requirements of solar panel frame profiles. It has low strength and is easy to deform during use.

Abstract

The invention relates to a method for manufacturing a solar energy battery board frame section bar, which comprises the following technical steps: adding an aluminum ingot into a smelting furnace to smelt and uniformly stirring aluminum liquid; after the aluminum liquid is stirred, carrying out first refinement; refining and uniformly scattering a slagging agent on aluminum slag; adding a magnesium ingot, aluminum-silicon medium alloy and rare earth alloy and fully stirring and mixing uniformly; carrying out second refinement and degassing; guiding refined aluminum liquid into a casting machine to cast; heating an aluminum bar on an aluminum bar heating furnace and extruding for molding on an extruder; and after the aluminum bar is extruded and molded, placing the aluminum bar into a heat treatment furnace to heat and preserve heat to obtain the solar energy battery board frame section bar. The section bar has bright surface, high strength, favorable toughness and corrosion resistance, lower manufacture cost and light weight, is difficult to deform, can be recycled and can save energy resources, reduce the environmental pollution and strengthen the running reliability.

Description

technical field [0001] The invention relates to a method for manufacturing solar panel frame profiles (hereinafter referred to as profiles), specifically for the manufacture of profiles, and belongs to the technical field of smelting and extrusion of nonferrous metals. Background technique [0002] When non-renewable energy sources such as electricity, coal, and oil are running out frequently, and energy issues have increasingly become a bottleneck restricting the development of the international society and economy, more and more countries have begun to implement the "Sunshine Plan" to develop solar energy resources and seek new impetus for economic development. Driven by the huge potential of the international photovoltaic market, my country's solar cell manufacturing industry is scrambling to invest huge sums of money and expand production in order to compete for a place. Profiles are essential components in solar cells. In the existing technology, the solar panel frame ...
