瓦楞辊压楞系数（γ）是瓦楞纸板生产线的核心工艺参数，该参数的选设直接影响到瓦楞纸板成型后的物理性能和纸板生产企业的经济效益。以A型瓦楞纸板为例，结合GB/T 6544-2008瓦楞纸板工艺参数的规定，根据瓦楞辊类型和设计原理，求出了A型瓦楞压楞系数；对比分析了压楞系数取上下限时纸板生产成本的差异，同时选择压楞系数差异较大的A型纸板进行了性能对比，最后提出了瓦楞压楞系数选设的参考建议。

Pressure coefficient of corrugated cardboard(γ) is the key technological parameter of corrugated cardboard production line, and the selection and setting of the parameter directly affects the physical performance of corrugated cardboard and the enterprise's economic efficiency. The pressure coefficient of A type corrugated cardboard was solved according to design principle and corrugated roller type combined with the prescription in the national standards GB/T 6544-2008. The production costs of corrugated cardboard with upper and lower limit of pressure coefficient was compared and analyzed. The performance difference of A type corrugated cardboard with large γ difference was compared. Suggestion on pressure coefficient selection and setting was put forward.
