大家知道,高速钢是一种价格很贵的高合金工具钢,用来制造要求性能很高的工具,而淬火加热温度对工具的质量(如高红硬性、强度、硬度、耐磨性等性能),有极其重要的影响。为了准确地测量加热温度,一般采用精密的测温装置,象PΠC型辐射高温计和—17型自动电位表和平衡电桥。这些装置不但可以指示出温度,而且可以自动记录和控制温度。 As we all know, high-speed steel is a very expensive high-alloy tool steel, used to manufacture high performance tools, and quenching temperature on the quality of tools (such as high red hardness, strength, hardness, wear resistance and other properties ), Has an extremely important impact. In order to accurately measure the heating temperature, the general use of precision temperature measurement devices, such as P? C radiation pyrometer and-17 automatic potentiometer and balance bridge. These devices not only indicate the temperature, but also automatically record and control the temperature.
