摘要
介绍了PSB785预应力混凝土用螺纹钢筋中化学成分设计、孔型设计、控制冷却工艺等研制开发过程。试制结果表明,钢筋的外形尺寸、表面质量和力学性能均满足标准要求。在总结试制结果的基础上,通过进一步对化学成分调整和控制冷却工艺的优化,可以生产出PSB830级别的钢材。
The paper introduces the process of research and development of chemical composition design,pass design,controlled cooling process for PSB785 pre-stressed concrete rebar.The trail results showed that the outline dimension,surface quality and mechanical properties of the rebar could all meet the requirement of the standard.On the basis of trail result summarization,PSB830 graded steel can be produced by further chemical composition adjustment and controlled cooling process optimization.
