摘要/Abstract

摘要： 通过调节三组水箱高压喷嘴冷却水的强度(轧制速度1.48 m/s,喷嘴内径80 mm,精轧前1^#水箱水压 ≤0.3 MPa,精轧后2^#水箱水压≥1.0 MPa,3B水箱水压≥1.0 MPa),控制φ60 mm CCr15轴承钢终轧温度950 ℃, 喷水后返红温度为680 ℃,使成品材网状为1.5~2.0级，稳定达到标准要求

关键词: GCr15轴承钢控制冷却网状碳化物

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.
