Technical Field

The invention discloses a method for rolling a large-size blank long material by utilizing a torsional guide, and particularly relates to a flexibly-arranged short stress path rolling mill and the torsional guide.

Background

For the existing continuous rolling long product production line, effective ways for improving the production efficiency comprise increasing the size of the initial rolling blank, improving the rolling speed of each pass and the like. If the rolling passes are not changed after the blank is enlarged, the deformation rate of each pass needs to be improved, and meanwhile, the matched rolling mill and motor equipment are replaced, so that higher equipment investment and longer production delay time are inevitably brought; if the mode of increasing the rolling pass (the number of rolling mills) is adopted, the adopted mode needs to enlarge the field and rearrange and install the rolling mills, even if the original rolling mills are not replaced, the construction amount of civil engineering and structures is larger, and the production is delayed for a long time.
