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

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.
