冷弯型钢是经济型钢中最有发展前途的品种之一,它与热轧,拉拨、冲压等生产方式相比,具有许多独特的优点,近年来受到世界各国广泛的重视和发展,美日发展较早,苏联及东欧各国近来发展迅速,现已总结了不少先进经验。我国这方面发展迟缓,几起几伏,远落后于国外。为借鉴国外经验,促进我国冷弯型钢生产的发展,本文对国内外冷弯型钢生产的现状,进行了较为全面系统的阐述。首先从冷弯型钢的特点,应用和发展历史开始,接着给出国外冷弯型钢的生产情况,列举了一些国家的主要生产厂家,重点介绍国外先进经验和发
Cold-formed steel is one of the most promising varieties in economical steel. It has many unique advantages compared with hot-rolling, drawing and punching and other production methods. In recent years, it has been widely valued and developed in various countries in the world. The development was earlier and the Soviet Union and the countries of Eastern Europe have been developing rapidly recently and many advanced experiences have been summarized. Our country has been sluggish in its development in this respect, with a few volts, lagging far behind its foreign counterparts. In order to learn from foreign experience and promote the development of cold-formed steel production in our country, this paper has a more comprehensive and systematic exposition of the status quo of cold-formed steel production at home and abroad. First of all, from the cold-formed steel characteristics, application and development history, followed by the production of cold-formed steel abroad, citing a number of major national manufacturers, with emphasis on foreign advanced experience and hair
