Mo-Nb贝氏体钢耙片挤压铸造

Squeeze Cast of Disc Harrow Piece of Mo-Nb Bainite Steel

给出了挤压铸造Mo-Nb贝氏体钢耙片的化学成分、工艺参数和新型模具结构。模具设有冷却水道和钢液溢流槽。为在耙片上铸出通孔,凹模设有浮动推杆。挤压铸造的Mo-Nb贝氏体钢耙片不仅生产成本低,而且具有较高的硬度、韧性和较好的耐磨性。

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.
