A high-precision shape detecting system of cold rolling strip is developed to meet industrial application, which mainly consists
of the shape detecting roller, the collecting ring, the digital signal processing (DSP) shape signal processing board and
the shape control model. Based on the shape detecting principle, the shape detecting roller is designed with a new integral
structure for improving the precision of shape detecting and avoiding scratching strip surface. Based on the DSP technology,
the DSP shape signal processing circuit board is designed and embedded in the shape detecting system for the reliability and
stability of shape signal processing. The shape detecting system was successfully used in Angang 1 250 mm HC 6-high reversible
cold rolling mill. The precision of shape detecting is 0.2 I and the shape deviation is controlled within 6 I after the close
loop shape control is input. 相似文献

【目的】:采用响应面法筛选马脂脱色工艺的最佳时间、温度及脱色剂用量,为工业生产提供理论依据。【方法】:以脱酸后马脂为原料,选用不同的脱色剂对其进行脱色,选出合适的脱色剂。以马脂脱色率为评价标准,考察了脱色温度、脱色时间、脱色剂用量对产自新疆的马脂脱色效果的影响。采用Box-Behnken响应曲面设计确定最佳的组合条件。【结果】:活性白土对马脂脱色效果最好,通过响应面分析法得到最佳脱色工艺条件为:温度61℃,时间32min,活性白土用量5.25%。在该优化条件下,马脂的脱色率可达71.01%。【结论】:响应面分析方法回归方程合理,并且能够预测各实验因素与响应值的关系,最终确定了马脂的脱色工艺参数。可见分光光度法与传统比色方法相比,具有操作简便、灵敏度高、重现性好的特点。 相似文献

目的:通过添加适宜剂量的抗氧剂和增效剂提高马脂的稳定性,并考察温度、湿度和光照对马脂的影响。方法:采用Schaal耐热试验法,以过氧化值为指标,确定加入马脂中最佳抗氧剂及其剂量和增效剂的量。结果:诱导期开始之前,温度对马脂的氧化过程影响最大;诱导期开始至终止,湿度对马脂氧化过程影响最大。在马脂中添加茶多酚的剂量为0.03%,柠檬酸为0.04%时,抗氧化效果最佳。结论:常温避光干燥条件贮存马脂时,添加了0.03%茶多酚和0.04%柠檬酸的马脂的贮存时间大大延长,抗氧化能力比空白对照组提高约54倍。 相似文献

Radiation damage of Lu2SiO5:Ce (LSO:Ce) crystals was investigated through intense UV light. An absorption band at 435 nm was observed in the transmission spectrum of the damaged LSO:Ce crystal, similar to that of absorption band caused by gamma ray irradiation. GDMS analysis for LSO:Ce crystals revealed the existence of impurities, such as Yb in the crystals. The impurities might be responsible for the optical absorption of the color center and the radiation center. 相似文献
