Editor's note: Be "ahead" and take on the responsibility of "taking the lead". Shandong Radio and Television Station launched the column "Under the guidance of Xi Jinping Thought on Socialism with Chinese Characteristics for a New Era, work hard and take the lead", which deeply explores the good practices and experiences of 16 cities in the province in promoting high-quality development and shows the vivid practice of various places in writing the chapter of Shandong with Chinese characteristics.
Qilu.com Lightning News, January 13th: Technological innovation can give birth to new industries, new models, and new momentum, and is the core element of developing new quality productivity. Weifang has a strong gene for technological innovation and has been rated as a national advanced city for scientific and technological progress many times, successfully entering the ranks of national innovative cities. At the Shandong Provincial Science and Technology Conference held in July 2024, Weifang City won 17 provincial science and technology awards, of which the number of provincial first prizes for scientific and technological progress ranked first in the province.
As a high-tech enterprise integrating R&D, production, sales, import and export trade, new material research and high-end equipment manufacturing, Weifang Oriental Steel Pipe Co., Ltd. has focused on steel anti-corrosion technology for many years. It is a key unit in the National Low-carbon and Environmentally Friendly Technology Promotion Catalogue, an experimental base of the National Marine Corrosion Protection Engineering Technology Research Center, and a single champion enterprise in Shandong Province's manufacturing industry, Shandong Province's specialized and new small and medium-sized enterprises, and one of the first pilot enterprises for the construction of Shandong Province's green, low-carbon and high-quality development pilot zone.
At Oriental Steel Pipe, Lightning News reporters saw zinc-aluminum-magnesium steel pipes wearing "anti-corrosion clothing". This type of steel pipe not only exhibits super corrosion resistance in high temperature, high humidity and high salt environments, but also can achieve self-repair of "wounds". In July 2023, the "300,000 tons per year new heavy-duty anti-corrosion marine engineering materials project" developed by Weifang Oriental Steel Pipe Co., Ltd. was officially put into production. This production line is not only the world's first "production line integrating ecological clean steel surface with zinc-aluminum-magnesium technology", but also the first "thick plate high-magnesium high-aluminum rare earth alloy anti-corrosion technology steel coil production line" in China. It mainly produces zinc-aluminum-magnesium rare earth alloy anti-corrosion strip steel and pre-punched zinc-aluminum-magnesium alloy anti-corrosion strip steel, which can achieve an annual output of 300,000 tons of new materials, generate 1.5 billion yuan in revenue, and 100 million yuan in profits and taxes.
By adding aluminum, magnesium and some rare earth elements to zinc liquid to form a ternary alloy coating, the zinc-aluminum-magnesium rare earth alloy coating has four major characteristics: super corrosion resistance, incision self-repairing, high hardness wear resistance and easy processing. Among them, the corrosion resistance is 10-15 times that of ordinary galvanizing, and can be used in new energy photovoltaics, marine photovoltaics, prefabricated buildings, electrical equipment and other civil fields and military and civilian dual-use marine anti-corrosion fields. At present, Oriental Steel Pipe's aluminum-magnesium alloy anti-corrosion technology has reached the international advanced level, solving the "bottleneck" problem of heavy marine anti-corrosion.
