“A new method for the determination of vanadium Aluminum Alloy and aluminum, which is independently researched and developed by us, enables the direct determination of aluminum elements and eliminates the interference of vanadium elements on the determination of aluminum element content. While ensuring the accuracy of the measurement results, it shortens the inspection time and significantly increases the The inspection efficiency has the advantages of high accuracy, good precision, and high detection speed, etc.” The person in charge of the related technology of Chenggang, Hebei Iron and Steel Group, briefed the reporter.

It is understood that vanadium aluminum Alloy is an additive for the production of Titanium alloys and vanadium-containing special alloys. Adding vanadium aluminum alloy can effectively improve the heat resistance and cold workability of the alloy, so that the alloy has better welding performance and mechanical strength. As a new type of alloy material, vanadium alloy has high strength and light weight, and is widely used in aerospace and other advanced national defense and civil industrial fields. Over the years, only a few developed countries in Europe and America have achieved industrial production of vanadium and aluminum products. In order to occupy the high-end market of vanadium products, Chenggang successfully used vanadium and aluminum alloy products in 2013 with the “electrical aluminum heat method” to fill the gaps in the world. However, the ratio of vanadium and aluminum in vanadium alloys varies greatly with product grades. Previously, there have been relatively mature methods in the vanadium content inspection industry, and indirect detection methods are commonly used for aluminum content detection. This method requires the determination of multiple elements, the cumbersome operation, high monitoring costs, and low accuracy, can not provide quality data for production in time, affect the efficient production of vanadium aluminum alloy products. The “Determination of Al Content in Vanadium Alloys Directly” by Chenggang’s self-developed technology has enabled the highly efficient determination of aluminum elements. With the accuracy of the measurement results assured, the detection efficiency of aluminum content has been greatly improved. The production efficiency of vanadium products will have a positive effect on promoting the upgrading of vanadium products. At present, this technology has obtained national invention patents.
