不平度不平度waviness buPingdu不平度(waviness)扁平轧件(如板带材)波浪形弯曲的波浪高度与长度之比，旧称波浪度。宽板材的波浪(见板形缺陷)有时出现在宽度中央、有时出现在两侧边、有时出现在一侧边，分别叫中浪、双边浪、单边浪;还有时出现在板宽的1/4处，叫1/4浪。板带越薄、越宽和材料强度越高，波浪越严重。有的产品标准规定，冷札钢板和钢带的不平度按表面质量、宽度和厚度划分档次。强度级别高的钢板不平度的上限允许略有增加。热轧钢板和钢带的不平度按厚度分档，强度级别高的钢板及调质钢板，不平度值允许略有增加。 造成不平度的原因是:压下蚤过小，辊型凸度过大或轧辊热膨胀，易产生中间浪，压下量过大，轧辊弯曲，辊型凸度过小，轧辊过冷或轧辊磨损易出现边浪，轧件两侧压下不相等或两侧冷却不均，则出现一侧浪。另外板面润滑不均，轧制时张力过小，轧件也会出现浪形。防止和消除波浪的方法是采用板形控制、弯辍技术、移辐技术、分段冷却，通过平整机平整，辐式矫直或张力矫直等。 (崔峰)
