Abstract

The blast furnace is used to smelt iron in the steel industry. Ore and cokes are input and hot air is blown into the chamber of the blast furnace. In the high temperature environment, the wear between the stave and the materials makes the cooling stave thinning by the downward movement of the materials in the blast furnace. The thickness of the cooling stave should be aware in order to prevent leakage of coolant into the furnace chamber and to make actions before the failure. The unique ultrasonic sensor which can approach the cooling stave through the cooling line was developed to measure thickness of the worn cooling stave. The ultrasonic sensor has cylindrical face to contact inner surface of the cooling line in the stave. The ultrasonic sensor is flexibly bendable to pass the bended pipe of inlet and outlet port of the cooling line in the stave.
利用超声波技术测量高炉冷却线铜壁厚度
在钢铁工业中,高炉是用来冶炼铁的。输入矿石和焦炭,将热空气吹入高炉炉膛。在高温环境下,冷却壁与物料之间的磨损使冷却壁在高炉内由于物料的向下运动而变薄。要注意冷却壁的厚度,防止冷却剂泄漏到炉膛内,在故障发生前采取措施。研制了一种独特的可通过冷却线接近冷却壁的超声波传感器,用于测量磨损冷却壁的厚度。超声波传感器的圆柱形表面与冷却线的内壁接触。超声波传感器可灵活弯曲,通过冷却线进出口口的弯曲管。
