| 摘 要： | 分析了PCM脉冲编码技术中存在的不足，提出一种改进型的PCM脉冲编码技术来实现气体流量的精确控制．在原有PCM流量控制阀组中加上一个定差减压阀，使压力差近似保持定值．利用计算机便能精确、快速地控制流量的大小．此方案已成功地应用在数家炼钢厂的吹氩控制中．

| Abstract: | The fault of pulse code modulation technique is analyzed in the paper, and an ameliorated PCM is brought forward in order to control gas flux accurately. An invariableness pressure decompression valve is added to common PCM to keep pressure discrepancy invariable approximately. With the computer, the flux can be controlled accurately and fleetly. The scheme has been used successfully in controlling argon flux in several steelworks. |
