Short-Stress Rolling Mill

The shorter the stress line in the mill stand, the smaller the amount of elastic deformation generated, the greater the rigidity of the rolling mill and the higher the precision of the rolled product. When used as a section rolling mill, it does not only have a high radial rigidity but also has high axial rigidity.

SY model high rigidity rolling mill is a new type of houseless short-stress rolling mill, suitable for small and medium-sized rolling mill renovation, and also for small continuous rolling and semi-continuous rolling plants. For example, in a small semi-continuous rolling mill with an annual output of 150,000 to 200,000 tons, 1202 and 1502 continuous casting billets are used, rough rolling mill is with the roll diameter is Ф500mm×2, and the rolled parts after cutting head by flying shear enters the diameter Ф350×4 and the diameter Ф300×4 continuous rolling mills.
