specific Embodiment approach
[0032] The main chemical element content (weight percentage) of the steel is: C content 0.17% ~ 0.23%, Mn content 0.30% ~ 0.60%, Si content 0.15% ~ 0.40%, S content ≤ 0.030%, P content ≤0.030%, the content of Cr is 1.25%-1.75%, the content of Ni is 3.25%-3.75%, the content of Cu is ≤0.25, and the balance is Fe.
[0033] The steps of this method are as follows:
[0034] Step 1: Prepare intermediate ring blank
[0035] Such as figure 1 As shown, according to the structural characteristics of the bearing steel multi-step large special-shaped ring 1, the forging cross-section is cut layer by layer equidistantly from the height direction with the help of drawing software, and the cross-sectional area data of the multi-step large special-shaped ring 1 is obtained and a curve 2 is made, as shown in figure 2 As shown, the relationship between the cross-sectional area and height of the multi-step large-scale special-shaped ring 1 is obtained; then according to the change trend of th...
