为测量高炉炉底耐火材料的残留厚度,现在一般都采用在炉体各处设置温度计,由传热计算的值估算耐火材料的残留厚度。但此法存在精度和响应速度不足问题。因此,新日本钢铁公司开发了用碰撞弹性波测量法测量耐火材料残留厚度的技术。 In order to measure the residual thickness of the refractory in the hearth of the blast furnace, thermometers are generally installed throughout the furnace body to estimate the residual thickness of the refractory from the value calculated by the heat transfer. However, this method has the problem of insufficient accuracy and speed of response. As a result, Nippon Steel Corporation has developed a technology to measure the residual thickness of refractory materials by collision elastic wave measurement.
