The shape and size of bainitic Martian composite wear-resistant cast steel lining plate are obtained by surveying and mapping the shape and size of the imported lining plate. The physical drawing of the imported lining plate is shown in Figure 1. The processing drawings and main dimensional parameters of the lining plate designed and developed after surveying and mapping are shown in Figure 2. It can be seen from Figure 2 that the maximum outer diameter of the moving cone lining plate is 1835mm and the height is 942mm, and the maximum outer diameter of the fixed cone lining plate is 2000mm and the height is 794mm.

Combined with the actual production conditions of the lining plate manufacturer, the shape, size and production requirements of the bainite Martian composite wear-resistant cast steel lining plate, the casting processes for the moving cone and the fixed cone lining plate are formulated respectively, which are cast by sand mold. The sand mold and the combined box are shown in Fig. 3.
