ZCuAl11Fe3 adopts measures such as controlling rolling temperature, reduction amount, cooling rate, and final rolling temperature to achieve good strength and toughness of the steel plate. The mechanical properties of good hao are due to the difference in grain size between the γ and α phases, and the refinement of the α structure is mainly achieved through the refinement of the γ grains; After compression in the non recrystallization zone, deformation below the recrystallization temperature generates a "spiral addition" of gamma grain structure, forming finer alpha grains. Hot rolled steel plates have higher yield strength, lower impact transition temperature, good cold formability, especially cold bending performance, toughness, and weldability after deformation [3]. In the formation of container heads, normalizing not only improves the forming process performance of hot-rolled plates, but also controls the tensile strength of hot-rolled steel plates with controlled rolling and cold rolling, ranging from 80 to 120 MPa; Compared with hot-rolled steel plates, the deformation force during head forming is much smaller, and the deformation amount can be almost ignored. Moreover, the subsequent cooling control is not as good as that of hot-rolled steel plates. As a result, the original grain size of hot-rolled steel plates after normalization is shown in Figure 2 (b) and 2 (c). Using this information, the forward slip value of a rack can be calculated, assuming that the exit speed of the strip steel on the fourth rack is the same as the roll speed on the fifth rack. If the amount of pressure on the fifth rack is low, then this assumption is valid. In actual production, the forward slip value on the fourth stand was calculated for 54 rolls of low carbon steel (2.6 × 0.42 × 940mm) of the same specification after F rolling. The calculation results indicate that as the rolling amount on the fourth stand and the wear of the working rolls increase, the forward slip value rapidly decreases to a small value of about 0.1%. When the current sliding value falls below this critical value, steel strip may occur. For this F, when the rolling capacity of the fourth stand rolling mill reaches 350km, the problem will be very serious and the working rolls must be replaced. There is a strong relationship between forward sliding and roller wear, as the surface roughness of the roller decreases with the amount of roller wear, resulting in gaps between the rollers.
