热轧带钢宽展及宽展量计算
|
摘要
宽展是热轧带钢生产工艺中的一个重要组成部分,不同的压下规程中采用的宽展形式不同,实际的宽展量差别也很大。由于影响宽展的因素很多,宽展量的计算非常复杂。根据不同的坯料规格和产品规格等合理选择恰当的宽展方式,不同宽展形式下宽展量计算方法也不同。强迫宽展要准确计算宽展值十分困难,一般只能根据经验公式估算;自由宽展推荐采用采利柯夫宽展公式计算宽展量,其结果比较符合实际。
The wide spread is an important part of the hot rolled strip production process. The wide spread forms used in different pressing procedures are different, and the actual wide spread varies greatly. Because of the many factors that influence spread, the calculation of the spread volume is very complicated. It is reasonable to choose the appropriate width form for different billet specifications and product specifications, and the calculation method of the spread quantity under different spreading forms is also different. It is very difficult to accurately calculate the spread of forced spread, and it can only be estimated based on empirical formula. It is recommended that the A.И.Целикоь spread width formula be applied to the free spread, the results are in accord with the reality.
