中厚板成材率的影响因素与改进措施

INFLUENCING FACTORS AND IMPROVING MEASURES OF MEDIUM AND HEAVY STEEL PLATE

中厚板成材率的影响因素包括品种规格结构、氧化烧损量、板型控制、钢板厚度负偏差控制、剪切量以及废品率等,在定量分析各因素对成材率影响量的基础上,提出了提高成材率的具体方法。通过优化板坯加热过程、合理使用AGC厚度控制系统以及平面形状控制系统对厚度和板型进行控制、优化剪切余量控制等一系列措施,邯钢中板厂的中厚板成材率得到稳步提高。

The influencing factors of the yield of medium thick plate include the variety and specification structure,the amount of oxidized burning,the control of plate shape,the negative deviation control of plate thickness,the shear amount and the rejection rate,etc.On the basis of the quantitative analysis of the influence of each factor on the yield,the specific methods to improve the yield of medium thick plate were put forward.Through optimizing slab heating process,using AGC thickness control system and plane shape control system to control thickness and plate shape,optimizing shear margin control and a series of measures,the yield of medium thick plate in Hangang Middle Plate Plant has been improved steadily.
