The research and development of high performance powder metallurgy high speed steel by acceptance
Update£º2012-06-13
Antai technology co., LTD take the Beijing municipal science and technology commission of 11th five-year project of science and technology research and development of high performance powder metallurgy high speed steel project (project number: Z07000300700704) successfully passed the acceptance, has been put into trial production. This project lasted three years, using aerosol + HIP + precision forging process, the key to solve the control technology of oxygen content and inclusion and related equipment renovation, product oxygen content is less than l0010-6 (100 PPM) finished product room temperature greater than 67 HRC hardness, bending capacity is greater than 4000 mpa, comprehensive performance and the performance is close to similar foreign products. Firms can now produce AHPT15 and AHPT15M, annual production capacity up to 50 tons. During the 12th five year, the company will according to the market demand continued series product development and industrialization of technology research. Powder metallurgy high speed steel (PMHSS) main characteristic is through the use of powder metallurgy process, from material to fundamentally solve the ordinary carbide segregation of casting high speed steel, coarse grains and other issues, but also can add large amounts of alloying elements in steel. Material tenacity, therefore, greatly improve, improve the tool performance and service life, very suitable for used in the processing situation of high impact cutting and metal removal rate (such as deflection, intermittent cutting cutting, etc.). Powder metallurgy high speed steel production began in the 1970 s, American Crucible factory and Sweden Stora factory (now France Erasteel company) for industrial production, has been monopoly by foreign industrial technology. China's iron and steel research institute for military needs and preparation technology of powder metallurgy high speed steel were studied, but due to factors such as market and cost, development and production of powder metallurgy HSS had stalled, this topic is based on the technology for powder metallurgy HSS industrialization research. Powder metallurgy high speed steel is a high performance of superhard cutting tool material system important constituent, is the production abroad of choice for high performance, large size, complicated shape cutting materials, especially in the gear cutting tools, broaches and all kinds of milling cutter and so on big size has obvious advantages in manufacturing, sophisticated tools. The 12th five-year period, with the state council about accelerate the decision of the cultivating and developing strategic emerging industries ", as well as China's automotive industry, aircraft industry, electricity, steam turbine, high-speed and large petrochemical equipment in the areas of rapid development, will further encourage China's high-end equipment and manufacturing technology towards high speed, high efficiency, composite, intelligent and environmentally friendly direction. Need not only in terms of processing and manufacturing of sex of whole of large, complex shape cutter, and a growing number of difficult processing of special materials, cutting tool material hardness, bending strength, impact performance etc. Also put forward more and more high request. Therefore, the development of powder metallurgy high speed steel is not only the progress of the tool material and the embodiment of the comprehensive strength of powder metallurgy technology in China, and has become the foundation of the revitalization of equipment manufacturing industry in our country and one of the key technologies. Right now, the powder high speed steel production mainly focused on seven enterprises, a total capacity of up to about 22000 tons. Powder metallurgy HSS already account for more than 10% of high speed steel production, the use of powder metallurgy high speed steel ratio more than 15%. In the next five years, China's market demand for powder metallurgy high speed steel materials and products, with exports of up to 1500 ~ 1500 tons. |
