PQF轧机是一种新型连轧管轧机,以其高质量、高产量和高技术水平等系列优点成为当今热轧无缝钢管生产技术的主流。孔型设计是连轧管工艺的核心,而轧件出口断面积是孔型设计中最重要的参数之一。通过理论推导的方式得出不同孔型形状的轧件出口面积。
PQF mill is a new type of tandem rolling mill. With its advantages of high quality, high output and high technology, PQF mill has become the mainstream of hot-rolled seamless steel pipe production technology today. Hole-type design is the core of continuous rolling process, and rolled out the cross-sectional area of the pass design is one of the most important parameters. Through the way of theoretical derivation, we can get the exit area of rolling pieces with different hole shapes.
