介绍了首钢长钢公司轧钢厂四车间轧制热轧带肋钢筋时，成品外观呈现周期性的波浪形状，经过测量严重部位的单位弯曲度在0.5%～0.6%，不满足GB 1499.2-2007钢筋混凝土用钢要求，同时也影响着成品外观质量；优化改进后，无论成品总长弯曲度还是单米弯曲度，均控制在国标4%以内，进一步提高了产品外观质量，提升了首钢长钢公司热轧带肋钢筋的品牌形象。
介紹瞭首鋼長鋼公司軋鋼廠四車間軋製熱軋帶肋鋼觔時，成品外觀呈現週期性的波浪形狀，經過測量嚴重部位的單位彎麯度在0.5%～0.6%，不滿足GB 1499.2-2007鋼觔混凝土用鋼要求，同時也影響著成品外觀質量；優化改進後，無論成品總長彎麯度還是單米彎麯度，均控製在國標4%以內，進一步提高瞭產品外觀質量，提升瞭首鋼長鋼公司熱軋帶肋鋼觔的品牌形象。

When observing finished products during the production of hot ribbed bars, periodic wave-shaped bending is found on the appearance of finished products. The most serious parts are measured to have a 0.5%~0.6% bending degree per me-ter which fails to meet the standard of GB 1499.2-2007 for concrete reinforcement steel,and has a bad influence on appear-ance quality of finished products.After improving the process, either bending degree of total length or per meter is controlled within 0.4% recording to the standard mentioned before.This achievement plays a great role in further improving appearance quality and contributes a lot to the hot ribbed bar brand image of SGCG.
