CPE機組縮口工藝的改進及效果

Improvement of Tube-end Pointing Process of CPE Pipe Plant and Operation Effectiveness

摘要: CPE軋管工藝是經(jīng)過改良的頂管工藝,但其仍然存在成品管長度短、金屬收得率低、生產(chǎn)能力低等缺點。為提高該軋管工藝的成材率,武鋼集團漢陽鋼廠通過具體分析CPE機組縮口工藝的特點,提出了CPE機組減少金屬切頭損失的工藝創(chuàng)新思路,改進縮口工藝,實施不切“杯底”的技術(shù)措施。此技術(shù)已在該廠Φ114mmCPE機組上應(yīng)用并取得良好效果。

Abstract: Although the CPE pipe-rolling process is in fact a well-modified push bench process,it has disadvantages as rather limited length range of finished tubes,low metal yield and small production capacity,etc. Based on analysis of characteristics of the CPE plant's tube-end pointing process,some proposals are put forward by the Hanyang Steel Works,Wuhan Iron and Steel (Group) Corporation to reduce the metal loss of the plant,including improvement of the tube-end pointing process and taking non-"cup bottom"-cutting tech-nique. The innovative technology has been applied to the Φ114 mm CPE plant of the company,resulting in satisfactory effectiveness.
