Recently, the high-corrosion-resistant zinc-aluminum-magnesium hot-dip galvanized steel sheet and its production method developed by HNGT Steel Technology Group have been granted a national patent.
As a new type of coating product, zinc, aluminum and magnesium has excellent corrosion resistance, processing characteristics and self-repair performance. It is a good substitute for traditional galvanized products, stainless steel, zinc-iron alloy and other materials, and can be widely used in photovoltaics and door industries. , Automobiles, home appliances and other industries, the market prospects are broad. But in the past, the patents of zinc, aluminum and magnesium products have been monopolized by foreign high-end enterprises.
This patented technology innovatively adds appropriate amounts of aluminum and magnesium to zinc liquid to form a unique low-aluminum-magnesium composition system, which can produce zinc-aluminum-magnesium products with high corrosion resistance and high surface quality, breaking the monopoly of foreign patents.
HNGT R&D team are committed to independent technological innovation and carrying out experiments. Through targeted research on the composition optimization technology, the orthogonal test was carried out by simulating core parameters, and considering the adhesion, surface quality, corrosion resistance and other dimensions, the 2.0% Al-1.5% Mg-RE low-aluminum-magnesium composition system was determined. . Carry out detailed early warning analysis in advance, avoid foreign patent barriers, obtain independent intellectual property rights, and quickly transform into industrial production.
On May 21 last year, the extreme thick zinc layer zinc-aluminum-magnesium product was successfully rolled off the assembly line at HNGT.
At present, the high corrosion-resistant zinc-aluminum-magnesium hot-dip galvanized steel sheet products produced by HNGT have integrated control technologies such as composition stability control technology, slag control technology, high surface production technology, black spot control technology, and rapid switching production technology for heterogeneous coatings, which solves the problem of industry There are more than ten common and difficult issues.
