美国芝加哥钢铁公司开发出一种采用一台设备同时测量出金属带材波浪的高度和频数的方法。测量精度达到ASTM标准要求。该装置已在欧洲和亚洲许多工厂采用。 在评定带材质量过程中,同时测得沿平行于轧制方向的水平轴向波浪的高度和频数之间关系数据特别重要。如现有标准中规定若卷材存在有1/4英寸波浪,如果是在长10英尺的长度中只存在
Chicago Steel Corporation of the United States has developed a method using a single device to simultaneously measure the height and frequency of metal strip waves. Measurement accuracy to ASTM standards. The unit has been adopted in many plants in Europe and Asia. In assessing the quality of the strip, it is of particular importance to simultaneously determine the relationship between the height and the frequency of horizontal axial waves parallel to the rolling direction. As the existing standard stipulates that if there is a 1/4 inch wave in the web, if there is only 10 feet in length
