Abstract
Using high hot blast temperature is a main trend of modern blast furnace operation, at the same time an effective and full-scale manual inspection tour of the hot blast pipelines including the hot blast main, branch pipes and bustle pipe, becomes increasingly difficult and time-consuming. Shougang Jingtang has two of China's most advanced blast furnaces with effective inner volume of 5500 m3, and the hot blast temperature reaches 1300℃. To avoid the inadvertence during manual inspection, the hot blast pipelines monitoring system was developed based on wireless sensor networks technology. Two kinds of wireless sensors are used to measure the surface temperature and deformation of the pipelines, wireless repeaters and collectors are used for measurement data transmission to upper computer. So inspector can monitor the real-time safety status of the entire pipelines in central control room, and wireless automatic monitoring has been realized. The paper refers to the design and installation of wireless sensors, the structure of monitoring system and application effect with real-time curves. The monitoring results show that this system has a very high accuracy and sensitivity and provides objective measuring data for the pipeline status judgment, especially the deformation data coming from wireless displacement sensor are essential to research the dynamic stress variation of the pipelines. This system increases work efficiency obviously, ensures the safety of the hot blast pipelines and the stability of blast furnace production and has very high application and popularizing value.
