本文简述了“STGY型数字式钢铁硬度分选仪”的测量原理。并给出了该仪器用于钢铁件硬度检测以及钢铁无损定碳及混料分选等检测实例。结果表明,该仪器检测硬度误差为±1HRC或±10HB。且能对碳素结构钢无损定碳,精度±0.03%C。可区分各种钢铁件混料。并用数字直接显示硬度的准确值大小及含碳量高低。结果直观、可靠。速度可达1,500件/小时。
This article briefly describes the measurement principle of “STGY Digital Steel Hardness Sorter”. And the instrument is used to detect the hardness of steel parts and steel non-destructive carbon and mixed material such as testing examples. The results show that the instrument detects the hardness error of ± 1HRC or ± 10HB. And carbon steel can be non-destructive carbon, accuracy of ± 0.03% C. Can distinguish between various steel mixing. And direct digital display of the exact value of hardness and carbon content level. The result is intuitive and reliable. Speed up to 1,500 pieces / hour.
