Shaanxi Steel and Panzhihua Steel achieved breakthrough in joint research and development of titanium-steel composite plates

Recently, Shaan Steel Group Hangang Company and Angang Group Panzhihua Xichang Panxin Vanadium and Titanium Metal Materials Co., Ltd. teamed up to make the thickness of the titanium-steel composite plate blank reach 306 mm through vacuum welding for the first time, and combined it with a 3500 mm medium and thick plate rolling method, successfully rolled wide and thin titanium-steel composite plate TA2/Q235B. This product has a smooth surface, a smooth shape, and good control of size accuracy, which has been highly recognized by customers.

As an ideal corrosion-resistant and high-strength structural material, titanium-steel composite plates are widely used in petroleum, chemical industry, metallurgy, water conservancy and hydropower, nuclear energy, aerospace and ocean engineering and other fields. At present, the domestic production method of titanium-steel composite plates mainly adopts the explosion method, and its production efficiency is greatly affected by the external environment such as weather. Superimposition is restricted by explosive cladding technology, and the production of titanium-steel composite plates is easily limited in terms of width and thickness. The adoption of vacuum welding + rolling composite production process can efficiently produce wide and thin specifications titanium-steel composite plates, thereby further improving production efficiency and enriching the varieties and specifications of titanium-steel composite plates.

Before the joint research and development and rolling of titanium-steel composite plates, Hangang established a special EVI (Supplier Early Intervention) product research team for composite plates in response to technical problems such as composite plate blank thickness of 306 mm, low heating temperature, and high deformation resistance., conducted on-site exchanges with technical experts of Pangang Xichang Panxin Vanadium and Titanium Metal Materials Co., Ltd. The technical personnel of the R & D teams of both parties have done a lot of preparatory work based on the equipment and technical characteristics of the 3500 mm medium and thick plate production line, repeatedly discussed and confirmed key technologies such as heating system, rolling procedures, shape control, and processing specifications, and formed a reasonable set of The rolling process plan overcomes many industrial technical problems such as low-temperature rolling of composite plates and wave shape fluctuations of steel plates, and ensures high quality and timely delivery of products.

In the future, Shaanxi Steel will continue to promote technological innovation and continue to deepen strategic cooperation with domestic high-quality titanium companies to inject impetus into promoting the high-quality development of my country's titanium and titanium-steel composite plate industry, and make new contributions to further promoting the development of the national titanium industry chain. Greater contribution.
