鋼管臥式擠壓生產(chǎn)技術(shù)和裝備的發(fā)展

Development of Horizontal-extrusion Process and Equipment for Steel Pipe

摘要: 近年來(lái), 為滿(mǎn)足我國(guó)核電工業(yè)、石油工業(yè)和化工行業(yè)對(duì)高端無(wú)縫鋼管產(chǎn)品的需要, 鋼管擠壓技術(shù)得到了進(jìn)一步的應(yīng)用和發(fā)展。2009年我國(guó)有1套立式擠壓機(jī)組和2套臥式擠壓機(jī)組投產(chǎn), 其裝備均達(dá)到世界領(lǐng)先水平。介紹了國(guó)內(nèi)外臥式擠壓生產(chǎn)工藝技術(shù)及生產(chǎn)裝備的發(fā)展歷程, 技術(shù)裝備主要包括坯料準(zhǔn)備、坯料加熱、鋼管擠壓、余熱淬火等設(shè)備。

Abstract: Over the recent years, the steel tube extrusion manufacturing technology has been further developed and adapted to meet the need for hi-end seamless steel tubular products as used in domestic nuclear power industry, petroleum industry and petrochemical industry.In 2009, one vertical extrusion plant and two horizontal extrusion plants with the technological level ahead of the world were built up and put into operation.Elaborated in the paper are the development progresses of manufacturing technologies and equipment of the horizontal extrusion mills as achieved both at home and abroad.Also described are the key technological equipment units of the said mill, including those for stock preparation, pipe extrusion, and immediate quenching process, etc.
