浅析英标、加标、美标螺纹钢的开发与生产

Brief Analysis on Development and Production of Reinforced Bar Accorded with British,Canadian and American Standards

天铁轧二制钢有限公司于2004年前后成功研制开发了英标BS4449—1988 GR 460级别钢筋、符合加拿大CSA G30.18-M92标准要求的400W级别钢筋及符合美国ASTMA615 GR 60级别钢筋。对以上标准的化学成分、外形尺寸、技术要求上的异同和特点进行了分析对比,指出了钢坯采购的化学成分要求差别,及轧钢工艺对性能的影响,为今后生产多种标准的钢材提供了依据。

Tiantie Rolling Mill 2 successfully developed British Standard BS4449-1988 GR 460 graded rebar, 400W graded rebar compliant with Canadian Standard CSA G30.18-M92 and American ASTM A615 GR 60 graded rebar around 2004. The author compares and analyzes the differences, similarities and characteristics of composition, dimension and technical requirement of the above standards, points out the required composition difference in billet purchasing and the influence of rolling process on properties, and provides a basis for the production of multiple standard steel.
