The Study of Rolling Temperature Condition Influence on the Formation of Hot Strip Cross-Section Rolled on the Longitudinal-Wedge Mill

摘要

The mill of new construction is proposed in the article. To calculate the specialized metal forming processes the software of finite element analysis - MSC Super Forge MSC Visual Nastran 4D was used. Stress-strain state (SSS) of the rolled workpiece and heavy-loaded units of the proposed mill was calculated. The influence of the rolling temperature regimes on formation of hot-rolled strips cross-section was investigated. The hot-rolled strips were rolled on longitudinal wedge mill. It is proved that the workpiece is deformed in the conditions of “soft” SSS in a mill of new construction, in other words the amount of the elastic deformation and displacement of the rolls units are small. The investigation has also proved sufficiently high fixity of the joints of roller assembly work stand as well as that the equivalent voltage does not exceed the maximum permissible value for the material strength in heavy-loaded units of the mill.
