Since the beginning of this year, Kunsteel, the birthplace of China's first cold-rolled titanium coil, has adopted three large-scale EB furnaces (electron beam cold bed melting furnaces) imported from the United States and Russia. Production efficiency, material yield, and product quality have been greatly improved, enabling the manufacture of low-cost titanium materials. In 2019, Kunming Iron & Steel is expected to produce 4,750 tons of titanium ingots, and its production and sales will increase by more than 25% over the previous year.
In April this year, Kungang Panyun Titanium was identified by the CIS Titanium Association as "a large-scale EB furnace titanium alloy melting training base for Russian technology worldwide". As the only titanium material manufacturer in Yunnan Province, since the beginning of this year, Kunshan Iron and Steel has played an active role in the construction of national marine projects relying on the national key research and development plan. Yunnan Titanium Co., Ltd., a subsidiary of Kunsteel, regards material genetic engineering as a major scientific research project, continues to take corrosion-resistant titanium alloys as its research direction, and takes the national marine engineering strategy as its starting point, and actively builds a database of corrosion-resistant titanium alloys for marine engineering, which is a national marine engineering project. Provide high-strength corrosion-resistant titanium alloy with superior performance. Through continuous deepening cooperation with scientific research institutions such as Harbin Institute of Technology, Tsinghua University, Kunming University of Science and Technology, Yunnan Institute of Metallurgy, and Yunnan Xinli Titanium Industry, Western Titanium Industry, Southwest Non-embroidery, Pangang Titanium Industry, etc., as of now, Kunshan Iron & Steel has 105 authorized patents, including 32 invention patents.
Scientific and technological innovation is an important force to promote the continuous development of enterprises. Today, Kungang Chufeng New Materials Group has been rated as "Yunnan High-tech Enterprise" and "Yunnan Enterprise Technology Center", and has undertaken the development of "low-cost, high-corrosion-resistant titanium and titanium alloy pipes and high-quality titanium belt manufacturing technology." And more than 10 national and (Yunnan) provincial and ministerial key R & D projects including "cooperative research on the design and manufacture of large-scale electron beam cold-bed furnaces and key technologies for melting and casting", "development and mass production of high-quality aluminum-vanadium series titanium alloys".
On May 15th, at the project scientific and technological achievements evaluation meeting held in Kunming, the "Research and Application of Strong Convection Argon Protection Wide Titanium Tape Shrouded Annealing Process and Equipment Technology" performed by Kungang Chufeng Group Yuntai Company The results were identified by the jury, and the overall technology reached the international leading level. This achievement has independently innovated the technology and equipment for the strong convective argon-protected wide titanium strip coil annealing process and equipment, and formed a complete process technology system for the strong convective argon-protected wide titanium strip coil annealing process. The quality index has reached or even surpassed The national standard and the American standard have created a new technical route for titanium strip coil annealing in the world. The annealing process technology and equipment are the world's first, which have effectively promoted the technological progress of the titanium industry in China.
On September 5th, Kungang Panyun Titanium Co., Ltd. used sponge zirconium as the raw material and used the electron beam cold bed melting furnace to successfully cast the first pure zirconium slab with a length of 6200 mm and a weight of 10 tons in Panxi. The blockade of this technology further optimized the structure of nonferrous metal products of Kunming Iron and Steel. In the next stage, Kunshan Iron & Steel Panyun Titanium Company will also have 3 EB furnaces, 1 hull furnace, and 1 spherical titanium powder production line to be completed and finalized, eventually forming an annual output of 10,000 tons of titanium and titanium alloy ingots and 70 tons of high quality. Production capacity of spherical titanium powder. By then, Kungang Panyun Titanium Company will become the nation's largest production base of titanium and titanium alloy melting and extension processing.
In order to expand the market and occupy the commanding heights of titanium products, Kungang Chufeng New Materials Group Cloud Titanium Co., Ltd. concentrated its efforts to overcome the limitations of the size of the isolation valve of the ingot drawing chamber, the mold structure design, high installation accuracy requirements, and the setting of the electron beam scanning track In the face of difficulties, the first 1530 mm wide titanium coil was smelted on September 13 to achieve a new breakthrough in product specifications. After months of careful planning and organization, the domestic widest 1560 mm EB furnace slab transformation was transformed Completed and realized the production of large and wide hot-rolled titanium strips, which laid a good foundation for the next step to produce more varieties and specifications of titanium materials and expand the market.
On December 10, a nationwide large-scale electron beam cold bed melting furnace (EB furnace), which was independently designed, manufactured and processed by Kunshan Iron & Steel with an investment of 500 million yuan, was commissioned in Panzhihua Yuntai Industrial Co., Ltd. The first titanium flat ingot with a length of 6 meters and a width of 1.55 meters was smoothly released in the sound of festive firecrackers, marking that "Kunshan Iron and Steel Titanium Industry" has entered the world's leading ranks in the field of vacuum melting. The EB furnace project lasted 374 days from the start to the hot test of the ingots. It poured the efforts of all technicians and builders, and realized the core system from the electron beam gun, high-voltage power cabinet, electron beam scanning control, to circulating cooling and vacuum extraction. , R & D design, manufacturing and installation, commissioning and verification, and control of the operating system of the supporting systems, such as feeding methods, ingot control, etc., are 100% domestically produced, with complete independent intellectual property rights, which complements China ’s difficulties in titanium, zirconium, nickel, etc. The shortcomings in the field of vacuum melting technology of molten metal materials have basically eliminated the threat of "neck neck" in the corresponding field and provided basic support for the country to develop new materials in high-end application fields.
