[0002] Ductile iron flooring is a type of flooring made of ductile iron material. This material is widely used in a variety of industrial scenarios due to its excellent performance. Ductile iron, also known as vermicular cast iron, is a high-strength cast iron material that is made by adding a certain proportion of spheroidizer (such as rare earth magnesium alloy) and inoculant (such as ferrosilicon or silicon-calcium alloy) to the raw materials and then undergoing a specific process to make the graphite exist in the cast iron in a spherical form. Compared with ordinary cast iron, ductile iron has higher strength, better toughness, wear resistance and corrosion resistance.

When the raw material in the mold box 2 is in a semi-solidified state and pores appear, the cylinder 41 is started, and the cylinder 41 is connected through the telescopic rod 42. The push plate 421 and the U-shaped inclined plate 422 are driven to move, so that the push plate 421 pushes the excess raw materials, thereby making the surface of the ductile iron floor smooth. At the same time, the U-shaped inclined plate 422 drives the raised inclined block 423 to move, so that the raised inclined block 423 drives the blocking plate 23 to move through the lifting inclined block 231. With the movement of the push plate 421, the excess materials are transported out of the mold box 2, so that the surface of the ductile iron floor is in a smooth state.
