钢材的机械性能是衡量钢材质量的主要指标之一,也是一项重要的交货标准。它的好坏,除了与轧制工艺条件有关外,还与钢质有直接关系。因此,如何控制好钢的化学成分,使之符合钢材性能的要求和根据已有坯料的化学成分预报钢材的性能,就成为轧钢技术人员最为关心的问题之一。钢材机械性能与钢的化学成分之间的关系迄今为止,尚无一个完整的理论的函数关系式来进行计算,只能用试验方法确定。生产厂只能对每批产品进行抽样检验,然后根据检验结果衡量钢材质量和作为交货的依据。实践表明,钢材机械性能与钢的化学
The mechanical properties of steel is one of the main indicators of the quality of steel, but also an important delivery standard. Its good or bad, in addition to the rolling conditions, but also has a direct relationship with the steel. Therefore, how to control the chemical composition of steel so that it meets the requirements of steel performance and predict the performance of steel based on the chemical composition of the existing billets has become one of the most concerned issues for steel rolling technicians. The relationship between the mechanical properties of steel and the chemical composition of the steel so far, there is no complete theoretical function to calculate, can only be determined by experimental methods. The manufacturer can only sample each batch of product, and then measure the quality of the steel based on the test results and as a basis for delivery. Practice shows that the mechanical properties of steel and steel chemistry
