现场实验研究了Assel轧机轧制过程减径量、减壁量、牌坊转角、钢管径壁比(d/t)和转速对20Cr钢管扩径量(Δd)、壁厚不均匀度(Δt)和轴向滑移系数(ηo)的影响。设计了轧制Φ70 mm×3 mm 20Cr钢管的辊型。工业生产结果表明
毛管尺寸为Φ76.3~76.7 mm×7.89~8.36 mm,Assel轧机轧制参数为喉径58 mm
芯棒52mm.转角15°
转速200 r/min时可轧出符合标准要求的Φ70 mm×3 mm的20Cr钢管。
Abstract
The effect of reduction of diameter
reduction of wall thickness
feed angle
tube diameter/wall thickness (d/t) and rotating speed of roll on diameter expanding amount (Δd)
degree of non -homogeneous wall thickness (Δt) and axial slide factor (ηo) for rolling steel 20Cr tube is studied during Assel mill rolling process. The roll shape for rolling Φ70 mm x 3 mm 20Cr steel tube is designed. Commercial production results show that with Φ76.3-76.6 mm x 7.89-8.36 mm shell
Assel mill rolling parameters- throat diameter 58 mm
mandrel diameter 52 mm
feed angle 15°
rotating speed 200 r/min the rolled Φ70 mm x 3 mm 20Cr steel tube meets the requirement of standard.
