济南铝板http://www.jngdly.com/的半成品和成品的生产过程,以及在箔材精整、退火、转运、包装等工序的生产过程中,不可避免的会出现一些缺陷,下面济南广大铝业的有关专家就给大家详细介绍一下。
Jinan, semi-finished and finished aluminum production process, as well as in the production process foil finishing,annealing, transport, packaging and other processes, and inevitably there will be some shortcomings, the majority of the experts following Alcoa Jinan give you details look.
   
济南铝板缺陷一部分是铸锭、铸轧带坯本身的缺陷,有时在注锭、铸轧工序可暴露,有时不能发现,而在后续的进一步加工过程中才能暴露;另一部分是在带箔材轧制、精整、退火、转运、包装等工序生产过程中产生的。这些缺陷的产生大部分是由于设备故障、违反操作规程、工艺参数调整不当、操作人员技术不够熟练和其他种种原因造成的,质量缺陷有许多种,主要是大量的针孔、厚度超差、平整度差、各种原因的断带等,减少这些缺陷是很有意义的。
Jinan defective part is aluminum ingot, billet casting defect itself, sometimes the injection ingot, the casting step may be exposed, may not be found, and in the subsequent further processing in order to be exposed; the other is in the foil strip rolling system, finishing, annealing, transport, packaging and other production processes generated in the process. Most of these defects are generated due to equipment failure, mishandling, improper adjustment of process parameters, the operator unskilled and various other causes, there are many kinds of quality defects, mainly a large number of pinholes, the thickness of the ultra-poor, flat poor, the broken belt for various reasons, to reduce these defects is very meaningful.
   
济南铝板http://www.jngdly.com/是在很薄状态下轧制的,对材料的厚度均匀性、轧制速度、张力、轧制油等都很敏感,在各种缺陷中最关键的是解决断带和针孔,尤其对高速轧机更为重要。
Jinan aluminum plate is rolled in a thin state, uniformity of thickness, rolling speed of the material, tension, are very sensitive to the rolling oil, the various defects in the most critical is the solution to the pinhole broken belt and, in particular, more important for high-speed mill.
