[0031] The main chemical element content (percentage by weight) of the alloy 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.
[0032] The flash welding forming process steps of the alloy large cross-section ring are as follows:
[0033] Step 1: Preheat. Fix the left end 121 of the bearing steel large-section ring blank 100 with an opening on the left fixture 111, and fix the right end 122 on the right fixture 112; set the working power of the flash welding machine to P=350KVA~900KVA, and the current I 0 =45KA~55KA, when the power is turned on, the distance between the openings at both ends is relatively large, and the current will flow from the left end 121 of the ring blank 100 through the back 101 of the ring blank 100 to the right end 122 of the ring blank 100 to form a circulating current, ...
