The advantages of short stress rolling mill are as follows:

　　(1) The high stiffness of the mill ensures the high precision of the product and is easy to realize negative deviation rolling.

　　(2) Symmetrical adjustment can be achieved. It is of great significance for stabilizing operation, improving operation rate, saving time of overhaul and replacement of guide beams, reducing operation accidents, avoiding process accidents such as elbow, impact and roll winding, and improving service life of guide.

　　(3) Because the rolling mill has changed the way of force transmission and changed the concentrated load of screw screw to the distributed load on both sides of bearing seat, the bearing and bearing seat have better stress condition, and the bearing life has been increased by more than 1.5 times than that of common rolling mill, thus the cost of products has been reduced.

　　(4) The roll system of short stress rolling mill is pre-installed and adjusted before roll change, and the new roll system can be replaced about 10 minutes after parking. The new roll system can be rolled over one or two steels to ensure that the product is qualified. Therefore, the rolling mill has good presetting performance, fast roll change and high yield.

　　Short stress mill, also known as no archway mill, is a kind of high stiffness mill. When used as section mill, it should not only have higher radial stiffness, but also have higher axial stiffness. At present, many types of short stress line rolling mills have been developed in China, such as GY, HB, CW, SY, GW and DW, among which three are representative.

At present, many types of short stress line rolling mills have been developed in China, such as GY, HB, CW, SY, GW and DW. There are three representative types: GY short stress line rolling mill, HB non-archway rolling mill and SY high rigidity rolling mill. These mills refer to Sweden's P-160. T-type non-archway rolling mills have been developed independently according to their different conditions, so their main stress lines are similar in structure, only in support modes and some specific structures are different, and each has its own characteristics.
