650 Short Stress Path Rolling Mill for Bar/Rebar Production Line
Short stress line mill, also known as non arch mill, is a kind of
high stiffness mill. When used as a section mill, it should not
only have high radial stiffness, but also have high axial
stiffness.At present, many types of short stress line mills have
been developed in China, such as :GY,HB,CW,SY,GW,DW, etc., among
which there are three representative ones. They are GY short stress
line mill,HB non-tailai mill, and SY high stiffness mill.These
kinds of rolling mills are developed by referring to the P-60
non-tailai rolling mills in Sweden and combining with their
different conditions. Therefore, the structure of the stress line
of the main bearing part is similar to each other, and there are
only some differences in the supporting mode and some specific
structures, which have their own characteristics.

Advantages of short stress rolling mill
The stress loop is short and the rigidity is high to ensure the
high precision of the product, and it is easy to achieve negative
deviation.
1. There are positive and negative threads at both ends of the
column, which can realize counterweight adjustment, and the rolling
center line remains unchanged. It can improve the operation rate,
save the time for maintenance and replacement of the guide and
guard beams, reduce operation accidents, avoid process accidents
such as rolling elbows, impact, and roll winding, and improve the
guide and guard life.
2. Convenient axial adjustment and small axial clearance.
3. The balance spring is used, the balance force is unchanged, and
the spring is compact in the bearing seat.
4. The rolling mill has good pre-adjustment performance, quick roll
change and high yield rate.
6. The bearing seat is automatically adjusted, and the four-row
cylindrical bearing is balanced in force, which improves the
bearing life.
| Summary comparison | Balance problem | Radial adjustment | Radial adjustment | Axial fixation |
| Old type short stress line rolling mill | Balance spring | Handwheel | Ring gear sleeve | Rectangular column |
| New type short stress line rolling mill | Damping rubber | Hydraulic motor | Worm gear and gear sleeve | Axial fixing sleeve tightly fit |
