Progress Made in Research on Technology Concerning Bimetallic Pipe（PartⅡ）

摘要: 介紹了國內(nèi)外雙金屬管的發(fā)展現(xiàn)狀,各種復合技術(shù)的生產(chǎn)工藝流程及其優(yōu)缺點。重點從技術(shù)優(yōu)勢、創(chuàng)新性、應(yīng)用種類等方面對離心工藝冶金熔合技術(shù)進行了詳細的闡述,并對離心鑄造復合管坯容易出現(xiàn)的缺陷進行了分析,提出了解決措施,對離心鑄造冶金熔合技術(shù)的發(fā)展前景和研究趨勢進行了展望。

Abstract: Elaborated in the article are the present situations of development of the bimetallic pipe both at home and abroad,and the manufacturing process flows of different tube cladding technologies,and the advantages and disadvantages of each of them. Also discussed in details is the metallurgical fusion technology with the centrifugal casting process,focusing on the technological superiority,innovativity,and application types,etc. Meanwhile,the common defects staying with the centrifugally-cast clad tube are analyzed,and preventative actions are in turn proposed. Moreover,the development prospect and research trend of this bimetallic pipe-making technology are forecast.
