Recently, the National Development and Reform Commission, the Ministry of Finance, and the Ministry of Industry and Information Technology agreed to include Luoyang Modu Tungsten & Molybdenum Technology Co., Ltd. in the development and industrialization of large-scale tungsten-molybdenum sheets, large-size high-purity sputtering targets and microcrystalline cemented carbides. The special fund plan for the development of emerging industries has been supported by the state's 64 million subsidies. This is the single new material research and development and industrialization project with the largest amount of state funding in Henan Province. It marks the development and deepening of new materials for tungsten and molybdenum rare metals in our province. The processing level has reached the domestic leading level and has a strong demonstration effect on the development of the industry. It is understood that with the development of nuclear industry, aerospace, electronics industry and modern processing technology, rocket nose cone, nuclear power high temperature heat shield, CNC machining, printed circuit board tools and other fields have a large demand for large-scale high-end tungsten and molybdenum products. increase. China's tungsten and molybdenum resources are abundant, ranking first and second in the world respectively. The production and export volume of tungsten and molybdenum products rank first in the world, but tungsten and molybdenum products are mainly raw materials and primary processed products, and the proportion of intensive processing products is low. There is a gap between the world's advanced level in terms of size, purity, density, etc. High-end tungsten and molybdenum products are basically all dependent on imports. In view of the problems in the tungsten and molybdenum deep processing industry, Luoyang Molybdenum Tungsten & Molybdenum Technology Co., Ltd. has implemented a large-scale tungsten-molybdenum wide plate, large-size high-purity sputtering target and microcrystalline cemented carbide research and development and industrialization projects, using a sound industrial chain. On the basis of the independent development and pilot test of tungsten and molybdenum raw materials, such as impurity purification and crystal form control, densification sintering, wide-thickness tungsten-molybdenum sheet rolling, etc., tungsten-molybdenum separation and purification, large H2 flow rate high-temperature reduction tungsten molybdenum powder The technology of multi-stage heat preservation and single-densification sintering, wide-thickness tungsten-molybdenum plate rolling and fine crystallization, further enhance the performance of the project, so that the width of the molybdenum plate exceeds 800mm, the thickness reaches 5-25mm, the single weight exceeds 400kg, and the width of the tungsten plate exceeds 500mm. The thickness is 6-20mm, the density reaches 98%, the film formation uniformity is more than 95%, and the technical level is internationally advanced. The implementation of this project is of great significance for extending the tungsten-molybdenum industrial chain, improving resource utilization and added value of products, breaking the dependence of high-end products of tungsten and molybdenum on imports, and promoting the transformation of resource advantages in our province to industrial advantages.
