小直徑熱軋荒管的生產(chǎn)工藝研究
INVESTIGATION ON PRODUCTION PROCESS OF HOT-ROLLED SMALL-DIAMETER TUBE
-
摘要: 介紹了用二輥或三輥軋機試軋φ57~76mm小直徑熱軋荒管的工藝參數(shù)、軋輥和芯棒的力能參數(shù)、荒管的表面質(zhì)量及幾何尺寸精度等。試驗表明,在工業(yè)條件下,用二輥軋管機組可生產(chǎn)出符合要求的小直徑熱軋荒管。Abstract: The article gives a description to the process parameters, roll and mandrel performance parameters, surface quality and dimensional accuracy of 57mm~76mm small-diameter pipes hot-rolled on two-roll tube mill or on three-roll tube mill. Experiment shows that under the industrial conditions the hot-rolled small diameter pipes, which can meet the reguirements specified, can be produced on two-roll tube mill.
