Abstract: With adjusting the rate of cooling water of high pressure spray jet at 3 water tanks(rolling speed 1.48 m/s,inside diameter of spray jet 80 mm,water pressure of Nol water tank before finishing rolling ≤0.3 MPa,No2 tank after finishing rolling≥1.0 MPa and 3B tank ≥1.0 MPa)to control finishing rolling temperature 950 ℃ for φ60 mm CCr15 bearing steel products and self tempering temperature 680 ℃ after water spray,the carbide network rating of prod- ucts was 1.5~2.0 to meet the requirement of standard.
