我国连轧管机组的建设与思考

回顾了我国连轧管机组的建设历史,分析了近几年国内无缝钢管生产情况,并对连轧管机组建设的严峻形势作了思考。分析认为:目前国内先进机组产能过剩,少量高端产品仍依赖进口,无缝钢管进出口差价有逐年缩小的趋势,出口增速放缓。针对目前的形势,建议无缝钢管生产企业加大新产品开发力度,走差异化发展道路。

Domestic Construction of Mandrel Pipe-rolling Mill and Relevant Consideration

The history of domestic construction of the mandrel pipe-rolling mill is reviewed,and domestic situations of seamless steel tube production over the recent years are analyzed. Also presented in the article are relevant consideration about the grim situation concerning construction of the mandrel pipe-rolling mill. The analysis leads to such a conclusion that at present the total production capacity of the advanced mandrel mills in the country is surplus compared with the actual market demand;certain amount of high-end products as rolled by the mandrel mill still depend on import, though in small quantities; the gap between the import price and the export price of seamless steel tubes is getting smaller and smaller year by year;and the tendency towards increase in export is getting slow down. To counter the present situation,it is recommended that seamless steel tube makers in the country make further efforts in development of new product types,and take the differentiation development orientation.
