三辊行星轧机为轧制圆材半成品和成品提供了一个经济的方法。这种仅有三个轧辊的装置在连续工作的基础上,可获得与通常圆钢或线材5～8机架连轧机组单道次连轧相当的延伸量。与以往的大压下量轧机,如皮尔格钢管轧机、森吉米尔带材轧机的非连续工作和轧锻联合成形不同,三辊行星轧机是第一种连续轧制的大压下量轧机。 The three-roller Planetary Rolling Mill provides an economical way to roll semi-finished and finished round products. This only three roller device on the basis of continuous work can be obtained with the conventional bar or wire 5 to 8 stand-alone rolling mill single-pass extension equivalent amount. Different from conventional continuous rolling and rolling forging, such as Pilz tube mill and Sendzimir strip mill, the three-roll planetary mill is the first continuous reduction mill.
