摘　　要：针对钼粉还原炉自动化生产线的工艺需求,设计了一种装料称重刮平与现场控制为一体的钼粉自动化装料称重装置。详细论述了该装置的机构组成及工作原理,并以ADuC824单片机为主控单元、EPM7128为逻辑信号处理单元构建完整的软硬件测控单元平台,设计制作了相应的部件单元和软件程序,并进行了现场试运行实验。实验结果表明,该称重装置重复性测量精度标准差为1.5 g,最大相对误差为0.11%,达到了钼粉还原炉自动化生产线所要求的称重误差控制要求。A weighing device for molybdenum powder automatic reduction line is designed based on the requirement analysis of reduction process. The components of the device structure and its working princi- ple are dealt with in details. An ADuC824 microprocessor is adopted as the control of core and the EPM7128 programmed logic array device is used as the logic signal processing unit to construct the com- plete software and hardware measuring and controlling unit platform. And the corresponding component units and software program are designed and made, and the in-situ operation experiment is carried out and the results show that the weighing error accuracy of the controller system referred as repeatability standard deviation is 1.5 g, and the maxim relative error is O. 11%, whereby reaching the process requirement for the molybdenum powder automatic reduction line.
