Quality Condition and Control Measures of Cold Rolling Ribbed Bar of Shandong Province

山东省冷轧带肋钢筋普遍存在延伸率达不到标准要求的问题 ,其主要原因是原材料与成品的力学性能不匹配 ,工艺控制不到位 ,质量管理不严谨等。应从原材料检验入手 ,加强工艺控制 ,严把质量关 。

The question which cannot be to achieve standard requirement for percentage elogation is existed universally in cold rolled ribbed bar product.The main causes produced above question are unreasonable matching between raw materail and machanical properties,unreasonable technique control and unstrict quality management,etc.For solving these questions it is needful to strength technique control,and to increase the product quality taking examination of raw material as first.
