Recently, Baotou Rare Earth Research Institute successfully completed the commissioning work of FRECH-QC830 cold chamber die-casting system of Germany to ensure the normal advancement of rare earth magnesium alloy die-casting project. For the next step to carry out rare earth magnesium alloy die-casting products to provide protection test process.
Die casting is a precision and efficient casting method. The quality of the products cast by die casting is high, the surface precision is high, the structure is compact, and has high hardness and strength. In recent years, with the demand for lightweight, die-cast magnesium alloy is widely used in rail transportation, automotive, aerospace and 3C products and other fields. Rare earth elements can effectively improve the mechanical properties and heat resistance of magnesium alloys, the production of rare-earth-containing die-casting magnesium alloy products, can better meet the market demand.
At present, there are few researches on die-casting technology of rare earth magnesium alloy at home and abroad. QC830 cold chamber die-casting system introduced by Baotou Rare Earth Research Institute is the most advanced die-casting system in Northwest China. The system clamping force reaches 8300 kN and the maximum injection pressure is 756 kN, the maximum projection area of 1242 cm2, can produce different sizes and complex shapes of thin-walled rare earth magnesium alloy castings, at this stage will be devoted to the development of rare earth magnesium alloy die-casting process technology research.
Baotou Rare Earth Research Institute of rare earth magnesium alloy pilot production line is a high-quality rare-earth magnesium alloy materials development, research and development of melting process, alloy manufacturing equipment research and development, custom alloy production, mass production as the core business of the integrated body. The rare earth magnesium alloy pilot line currently has 1500 t / a rare earth magnesium alloy production capacity, with a number of independent technology, can fully meet the needs of universities, research institutions and enterprises of rare earth magnesium alloy experiment and medium-scale production is required Promote the magnesium alloy material from laboratory to large-scale industrial transformation of the excellent platform.
Rare Earth Magnesium Alloy Research and Development team of Baotou Rare Earth Research Institute, based on technological innovation and development, closely combines the needs of the market to form rare earth magnesium intermediate alloy products covering the rare earth element series including magnesium lanthanum, magnesium cerium, magnesium neodymium, magnesium gadolinium and magnesium yttrium intermediate alloy , Zirconium-containing rare earth magnesium intermediate alloy products, rare earth magnesium alloy products to meet different needs of the field, while providing rare earth magnesium alloy, contact with the application of the terminal close to rare earth magnesium alloy die-casting, semi-continuous casting round bar, squeeze Pressure profile of technology development and product development, breakthroughs in rare earth magnesium alloy technical barriers and application barriers; for the introduction of rare earth magnesium alloy customized preparation of a new model to provide the corresponding technology and equipment support services and product solutions, as customers and products The bridge between the realization of cost-effective products and services.
