As a key tool material supporting the development of the manufacturing industry, the production and preparation technology of cemented carbide has always been the research and development direction that the world attaches great importance to.

The production and preparation technology of cemented carbide has always been the research and development direction that the world attaches great importance to

All aspects of industrial production of ultra-fine-grained WC-Co cemented carbide must be carried out under very high quality control standards; the key link is the preparation of ultra-fine raw material powder, the mastery and control of powder forming and sintering process. Using ultra-fine grain alloy preparation technology to improve the level of my country's cemented carbide products to upgrade their quality and add value should be based on a comprehensive grasp of the relevant knowledge system of ultra-fine powder and alloy systems, stable and perfect production process and technology, and large-scale manufacturing. The cost is low, and the analysis and evaluation techniques and methods are standardized and based on international standards, so that the product has a strong performance-price ratio and international market competitiveness.

It should be pointed out that the development of foreign ultra-fine cemented carbide production technology is a result of the combination, division of labor and cooperation of excellent international enterprises and research institutions under the clear common development strategic goal. After long-term, systematic and in-depth applied basic research and practical What is obtained through chemical development is a systematic project involving a wide range of areas.

State-owned and private enterprises and related research institutions in China's cemented carbide industry should learn from their successful experience in market-oriented operation, based on the existing material and technical foundation, and give full play to China's ability to concentrate resources to jointly tackle key problems, reduce enterprise development risks, and break through major common keys. The advantages of technology, through unremitting efforts: improve the batch preparation technology of high-purity, high-stability, low "hard agglomeration" ultra-fine powder raw materials; study the behavior of ultra-fine and nano-hard alloy powders under various pressure forming conditions Laws and evaluation methods of powder compact quality; master the densification and material migration laws of alloy blanks during sintering, accurately control the carbon content of the alloy and the growth of WC grains and the corresponding sintering technology; understand the alloy components and their The relationship between microstructural changes and material properties; carry out quantitative quality inspection and analysis and evaluation technology research on powders and alloys, and establish corresponding quality standards and databases; to effectively improve independent development capabilities and form high-performance products with China's independent intellectual property rights Ultra-fine-grained cemented carbide series products; also study the production safety and operator's industrial hygiene in the production of fine-grained cemented carbide, and take corresponding control measures to ensure civilized production.
