在宽厚板产线使用伽马射线测厚仪(Thermo-electron)进行钢板厚度测量。460MPa级抗震耐蚀耐火钢中板轧态的厚度公差统计结果为:公差范围0.08~0.40mm,平均公差0.23mm。厚度公差复合规程规定的范围之内,不会造成性能不合。
The thickness of the steel plate is measured by thermo-electron at the production line of the wide plate. The statistical tolerance of rolled thickness of 460MPa aseismic corrosion resistant refractory steel is as follows: the tolerance range is 0.08~0.40mm, the average tolerance is 0.23mm. Within the range specified by the composite thickness tolerance procedure, no performance deviation will be caused.
