| Abstract: | The chemical components,technical parameter and a new type of mould structure are presented for squeeze casting disc harrow piece of Mo-Nb Bainite steel.There are a path for cooling water and owerflow way for iron water in the mould.To cast a through hole on the harrow piece,a float mandrel separately is set on the container.Not only the production cost of disc pieces of Mo-Nb bainite steel squeeze cast is low,but also the harrow has many characteristics such as greater hardness,toughness and better wear resistance. |
