近年来,我国每年消耗高速钢材约2～3万t,其中定点工具厂的消耗量约占90%。高速钢热处理的特点,尽管单件重量并不大,但产量大、质量要求高,包括外观和防锈性能都要求达到高标准;因此,应围绕着高效率、高质量、低成本、省能源进行生产,要求工艺过程稳定、重现性好、适合批量生产,此外,应采取措施,不断提高刀具寿命。根据上述情况,展望高速钢热处理的发展前景着重讨论以下几个问题。一、加热炉各种中性盐浴是国内现用高速钢预热、淬火加热,冷却和回火的主要加热介质。其优点是生产效率高,操作方便,已较普遍地
In recent years, China consumes about 2 to 30,000 tons of high-speed steel annually, of which fixed-point tool plant consumption accounts for about 90%. High-speed steel heat treatment characteristics, although the weight of a single piece is not large, but the output is large, high quality requirements, including appearance and anti-rust properties are required to achieve high standards; therefore, should focus on high efficiency, high quality, low cost, energy saving For production, requires stable process, reproducible, suitable for mass production, in addition, measures should be taken to continuously improve tool life. According to the above situation, the prospects for the development of high-speed steel heat treatment focus on the following questions. First, the furnace Various neutral salt bath is the current domestic high-speed steel preheating, quenching and heating, cooling and tempering the main heating medium. The advantage is the high production efficiency, easy operation, has been more common
