頂管機組生產(chǎn)油管的實踐探索

An Approach to Producing Tubings with Push Bench Pipe Mill

摘要: 為了充分挖掘現(xiàn)有頂管機組的生產(chǎn)潛力,調整產(chǎn)品結構,提高經(jīng)濟效益,武鋼集團漢陽鋼廠對采用頂管機組生產(chǎn)J55、N80Ⅰ類鋼級油管進行了有益的探索,介紹了J55、N80Ⅰ類鋼級油管主要的生產(chǎn)技術難點、所采取的相應工藝技術措施和取得的效果。經(jīng)檢測及用戶使用表明,產(chǎn)品的化學成分控制良好,幾何尺寸精度高,力學性能優(yōu)良,表面質量好。

Abstract: Hanyang Steel Works, Wugang Group has carried out an approach to producing tubings of in steel grades of J55 and N80 Ⅰ, in a bid to tap the potential capacity of the push bench mill, restructure the product mix and enhance economic benefit.Described in the paper are the main technological difficulties and relevant technological countermeasures and the result in manufacturing the said tubings with the push bench mill.Relevant testing and the end-user's operation result show that the tubings are in possession of well-controlled chemical composition, high geometric accuracy, fine mechanical properties and good surface quality.
