美国钢铁技术专家断定,高炉放散管闸阀的快速准确定位能降低燃料费用,提高燃气锅炉运行可靠性,甚至可转卖煤气。然而使阀快速准确定位,收集及控制高炉煤气并非易事,除了要布置精敏的传感器及采用准确的反馈控制软件外,还需设置反应灵敏的闸阀伺服传动系统。这样才能将传感器发出的信号及时与执行指令的操作机构快速准确结合起来,最大限度地回收煤气。因此专家们在着重解决后半部技术问题。 U.S. steel technologists have concluded that the rapid and accurate positioning of the blast-gate valves can reduce fuel costs, improve the operational reliability of gas boilers and even resell gas. However, to quickly and accurately position the valve and collect and control blast furnace gas is not an easy task. In addition to disposing sensitive sensors and using accurate feedback control software, a responsive gate valve servo drive system is also required. In this way, the signal sent by the sensor can be promptly and accurately combined with the operating mechanism for executing the instruction to recover the gas to the maximum extent. Therefore, experts focus on the second half of technical problems.
