H型钢因其断面异型，轧制变形时金属流动性大，断面温度分布不均匀使得其断面组织均匀性很难得到控制。在建筑工程中H型钢的广泛应用，使得对产品的形状、尺寸精度和机械性能要求日益严格。在金属的塑性变形过程中，微观组织的演变对金属的机械性能有着很大的影响。为了研究组织对机械性能的影响，对产品的机械性能进行的拉伸实验并对组织性能进行了观测，分析了组织对机械性能的影响。并对轧制规程进行优化。

It is difficult to control structural homogenity of H-beam,because of the special section ,the metal flowing power is big and the section temperature is uneven .It is expanding strict to the shape of H-beam ,dimensional pre-cision and mechanical behaviour .In the process of the metal plastic deform , microstructure transmutation is great effect on the mechanical property .In order to analyse the effect of microstructure on the mechanical property , the tension test is operated and the microstructure effect on the mechanical property is analysed .the rolling rules is op-timized.
