    Innovation of Φ102 mm CPE Push Bench Plant and Effectiveness

    • 摘要: 介紹了江蘇常寶鋼管有限公司的國內(nèi)首套Φ102mmCPE新型頂管機(jī)組的特點(diǎn)、建設(shè)背景和發(fā)展現(xiàn)狀,以及機(jī)組投產(chǎn)以來在頂管和張力減徑的孔型開發(fā)、擴(kuò)大產(chǎn)品規(guī)格、工模具改進(jìn)、新產(chǎn)品開發(fā)和為提高生產(chǎn)線工藝能力等方面所做的技術(shù)改造。生產(chǎn)實(shí)踐證明,CPE工藝作為引進(jìn)技術(shù)是成功的,在無縫鋼管連軋技術(shù)的推廣應(yīng)用上也是成熟可靠的。項(xiàng)目投資費(fèi)用少、工藝簡單、特別適用于生產(chǎn)薄壁小直徑熱軋管。

       

      Abstract: Presented here in the paper are the main aspects of the first domestic Φ102 mm CPE push bench plant located in Jiangsu Changbao Steel Pipe Co., Ltd., covering the features, construction background and current development situation, and the technical modifications as made since the start-up of the plant, including pass development of the push bench proper and the stretch reducing mill, expansion of the product mix, improvement of the tools & dies, R & D of new product and enhancement of the technological capability of the production line as a whole. The operation practice of the plant demonstrates that as a technology introduced from abroad, the CPE process is applied successfully in the country, and as a continuous rolling process for seamless steel tubes, it is proven and reliable. The CPE process has such advantages as low investment, technologically simplicity and being particularly suitable for making small-sized, light-wall hot-rolled tubes.
