摘　　要：由于现场Φ158.3 mm规格芯棒短缺,为满足我厂生产需求,对原有Φ173系列孔型做了修改。通过使用连轧机数学模型进行验算,最终确定了使用Φ160.5 mm规格芯棒代替Φ158.3 mm规格芯棒轧制Φ139.7 mm×7.72 mm规格石油套管的专用孔型。Due to the lack of mandrels of Ф158.3 mm in work field,the original Ф173 series of passes are modified in order to satisfy the capacity requirements of our plant. With checking calculations using mathematical models of tandem mills ,the special passes are finally determined for manufacturing oil casings of Ф139.7 mm ×7.72 mm when the mandrels of Ф160.5 mm are used instead of Ф158.3 mm.
