氧分析仪在退火炉氧含量自动检测系统中的应用

Application of oxygen analyser in oxygen content auto-measuring system of an annealing furnace

介绍某进口退火炉使用一套氧分析仪对多个炉区氧含量进行自动检测的系统。一般氧分析仪测量精度为ppm,该氧分析仪测量精度达到10-20vol.%以下。该文介绍了该氧分析仪的测量原理。通过对氧分析仪初始化的描述,使读者了解氧分析仪的使用方法。通过对自动检测系统的分析,使读者了解氧分析仪和自动化系统的集成方法。

The paper introduces an oxygen content auto -measuring system, which uses a set of oxygen analyser to detect several heating zones of an inport annealing furnace. In general, oxygen analyser measuring precision is percent per million （ppm） , but this oxygen analyser measuring precision arrives below 10-20%. The oxygen analyser measuring principle is introduced. By description of initilization of oxygen analyzer, readers will know how to use it. By analysis of the auto - measuring system, readers will know how to integrate it with an automation system.
