The production and sales volume of vanadium products of HGCG increased by 85% year-on-year; additive manufacturing products have established cooperative relationships with nearly a hundred customers, and more than 20 batches of products have been delivered to customers; as the only domestic aviation-grade tablet vanadium manufacturer, aviation-grade The production and sales volume of tablet vanadium quadrupled year-on-year, winning the favor of international customers. The high-end vanadium products of HGCG are widely used in aviation, aerospace, military and high-end chemical industries, further enhancing market competitiveness.
Product upgrades with two 3D printers
On December 5, a reporter from China Metallurgical News came to the HGCG Additive Manufacturing Service Demonstration Center, and two 3D printers were running nervously. "We currently have two 3D printers, one for plastic products and the other for printing on metal materials," Li Lanjie, director of the vanadium and titanium vanadium-titanium research and development center of HGCG, told the reporter of China Metallurgical News.
Standing in front of the laser melting metal printer in the selection area, Changfu Zeng, a vanadium-titanium technology expert at HGCG and technical director of the Additive Manufacturing Service Demonstration Center, proudly introduced: "We are now printing aircraft impeller parts with titanium powder. The model design scheme can melt titanium powder and build it on the working surface in a few microseconds, and the tolerance after the product is completed can be controlled within 50 microns. "
Subsequently, a reporter from China Metallurgical News saw a display-sized square box (a non-metallic 3D printer) printing a sphere-shaped and bar-shaped trophy in the room adjacent to it. Staff Zhou Tao introduced: "This trophy is specially designed for customers. Because the 3D structure of the design model is complex and the model is unreliable, we use a non-metal machine to verify the model, then optimize it according to the molding situation, and then use metal materials to manufacture in batches." It turns out that the printing cycle of non-metallic machines is about 2 hours, and the printing cycle of metallic materials is generally more than 40 hours. In order to ensure that each product is a high-quality product, after receiving the order, the technical staff of Chengsteel Chengsteel Co., Ltd. repeatedly optimized the model design scheme and the non-metallic experimental modeling of the complex structure. This not only allows customers to see the trial samples as soon as possible, but also ensures that the model is reliable and successful at the time of printing on metal materials, which is welcomed by customers.
"China Metallurgical News" reporter saw in the corridor of the center, large and small dozens of product models are placed in turn. It turned out that from 3D printing crafts, printing stainless steel precision parts to manufacturing aerospace titanium alloy products, the center has established cooperative relationships with nearly a hundred customers, and more than 20 batches of products have been delivered to customers. These products are placed in the corridor. Model.
Domestic exclusive production of aviation tablet vanadium
In early December, the 20-ton aviation-grade tablet vanadium directly supplied by HGCG Steel to European high-end customers was well received by customers. Andrea Perfati, Director of Consumables and Ferroalloys, Jiegang JCDecaux International Trade Holding Co., Ltd. said: "The aerospace-grade tablets produced by HGCG have precise control of vanadium, and the content of potassium oxide and sodium oxide can be controlled at 0.3%. Below, as the basic raw material for manufacturing aerospace engines, it is favored by high-end customers. "
As the only domestic company capable of producing aviation-grade tablet vanadium (99% purity vanadium pentoxide), HGCG has an annual production capacity of more than 300 tons. Liu Chao, a vanadium-titanium technical expert at HGCG, said: "We rely on our technological advantages in the field of vanadium products, and independently developed a set of domestically-produced production processes with 9 national patents. Advanced technology and sophisticated production organization , To ensure the precise control of the vanadium composition of aviation-grade tablets. At present, we have established stable cooperative relations with 4 international high-end customers. "
Since the beginning of this year, HGCG has taken technological innovation as the lead and continued to innovate the process flow and raw material structure according to the needs of high-end customers. The precision process control has realized the improvement of aviation-grade tablet vanadium products. As of now, aviation Grade vanadium sales quadrupled year-on-year.
Not only that, the technical staff of HGCG continuously climbed the technical peak, successfully developed and mass-produced chemical-grade high-purity vanadium with a purity of 99.9%. Hesteel Chenggang's first domestic production process of high-purity powder vanadium products by ion replacement method has short process, high efficiency, and no pollution during the whole process. The particle size of chemical-grade high-purity vanadium reaches millimeter level. Demanding requirements of users.
In addition, HGCG made full use of HBIS's global technology innovation platform, and cooperated extensively with HBIS Dongda Industrial Technology Research Institute, the Chinese Academy of Sciences, and HGCG German Advanced International Technology Platform to jointly promote vanadium batteries and aerospace-grade vanadium aluminum Research and development of a series of "technical products" such as alloys have provided strong support for the construction of an international high-end vanadium-titanium new material industrial base by HGCG.
