The T-shaped ring with a smaller cross section is usually welded first and then rolled. The web is cut into straight strips. After the web and the face plate are welded, Figure 3 As shown, at this time, a straight long strip of T-shaped steel is formed, and then it is sent to the rolling machine for processing and forming.

The deformation of the T-steel reinforcement ring is likely to cause a decrease in strength and a risk of failure. Although the rolling machine has a certain degree of shaping during the pressing process, larger deformations cannot be shaped in place, and there is even the possibility of cracking during extrusion molding to produce defects.
