连轧管孔型系的辊缝调节量

Roll Gap Adjustment of Groove Series for Continuous Rolling Mill

当利用调节辊缝未获得要求的管子壁厚时,将会增大管子横向壁厚不均,损失轧管精度。研究了连轧管孔型系的辊缝调节量计算方法及其对管子横向壁厚不均的影响,给出了计算模型和实例。

In case of failure to get required wall thickness by adjusting the roll gap,transverse inhomogeneity of wall thickness will get more serious,neg atively influencing the dimensional accuracy of the pipe.Based on resea rch on the cal-culation method concerning adjustm ent amount of roll gap for groove series of the continuous rolling mill and negative influ-ence thereby on pipe transverse wall thickness homogeneity,related math model is worked out and examples are described.
