Abstract: The paper expatiated the structure and designed demand of the housing of a H1400 heavy cross wedge rolling mill developed by the authors. A coupling method of boundary element method and finite element method was adopted to numerically simulate the deformation of main parts during the process of cross wedge rolling and accurately calculate the strength and rigid of the mill. The results show that the designed structure of the housing of a H1400 heavy cross wedge rolling mill provides effective equipment for meeting the market demand and rolling large-sized shaft-parts.
