[China Aluminum Industry Network] Currently, the aluminum profile products produced by the anodizing process account for about half of the construction aluminum profile market. How to apply modern technology to the oxidation production line to increase production efficiency and promote energy conservation and emission reduction is a core concern of many aluminum processing companies over the years. Modern aluminum oxide production lines have different applications of information technology. Many companies have conducted informatization research. In general, these studies and implementations are partial. Such a local information system is like an island of information. The connection between each other depends on human input. It is easy to make human errors and lead to a drop in production efficiency. The majority of companies' production control systems use wired transmission for the control of processes. High wiring requirements increase costs. Studies have shown that the application of information technology and high-frequency oxidation power can increase industrial production efficiency and energy-saving electricity tariff by 10%, and reduce emissions and pollution by 25%. Therefore, the application of information technology and high-frequency oxidation rectifiers is the key to the transformation of aluminum processing companies. This article describes the application of information fusion, wireless control and automatic packaging and high-frequency oxidation power technology in vertical oxidation production lines. Technical characteristics Anodizing is a common method for aluminum profiles processing. Therefore, the comparison between silicon rectifiers and high-frequency oxidation rectifiers is a good model for promoting energy conservation and emission reduction and improving production efficiency. 1. Overview of Rectifier Development Oxidation rectification power supply is an indispensable important equipment for aluminum profile oxidation process. Its performance index largely determines the anodizing industrial production level, product quality and energy-saving effect. The early DC generator was the former generation power supply of the oxidation industry. By the generation of high-power rectifiers in the 1960s, there appeared the second-generation power supply of the oxidation industry—silicon rectifiers. However, these two generations of power supplies are bulky, With the disadvantages of energy consumption, low output indicators, poor accuracy, and inconvenient control, it was gradually replaced by a third-generation rectifier, a thyristor rectifier. Because of its high precision and convenient control, thyristor rectifiers have been widely used since the 1970s. However, thyristor rectifiers are still based on bulky, high-consumption power frequency transformers. Therefore, the disadvantages of large size, bulkiness, and high energy consumption are still present. Because the adjustment of voltage and current of the power supply is controlled by the open angle of the thyristor, a large amount of harmonic waves are generated, thereby contaminating the power grid. Since the thyristor operating frequency is in the low frequency band (50-60 Hz), It is not easily absorbed by filters, which obviously does not meet the requirements of cleaner production. In this case, the fourth-generation rectifier, which can overcome many of the shortcomings of thyristors, has emerged as a high-frequency oxidation source. The high-frequency aluminum oxidation power supply is not only small in size, low in consumables, high in efficiency, but also high in accuracy and easy to control, so it is rapidly accepted by the oxidation industry. Internationally, as long as it is a slightly advanced country, the SCR has basically been eliminated. The application of high-frequency switching power supplies in the domestic oxidation industry is also becoming more and more common.
