三辊可调式钢管定径机技术

Technique of Adjustable Three -roll Steel Tube Sizing Mill

简介了新型可调式三辊定径机的结构特点,提出了可调辊调节时对外径精度影响的关系式,进行了新型可调式三辊定径机与二辊式定径机的调整精度比较。

The paper covers such aspects of the adjustable three -roll steel pipe sizing mill as a briefing on the mill structural characteristics,the re lationship between roll adjustment and the tube O.D.accuracy and an adju stment accura-cy comparison between the newly deve loped adjustable three -roll sizing mill and the conventional two -roll s izing mill.
