热锻模具是农业机械制造中广泛使用的零件精加工的重要装备。以往国内铸造热锻模具只采用传统锻钢，如５ＣｒＭｎＭｏ等制造，这是我国铸造热锻模具寿命低的根本原因。作者根据铸造金属的特点和热锻模的工作条件，经合金化，获得了一种适用于铸造生产的新型铸造热锻模具钢...
Hot forging die is widely used in agricultural machinery manufacturing parts finishing important equipment. In the past, domestic forged hot forging dies only used traditional forged steel, such as 5CrMnMo, which is the fundamental reason for the low life of our foundry hot forging dies. Based on the characteristics of the foundry metal and the working conditions of the hot forging die, the author obtained a new type of foundry hot-forged die steel suitable for casting production by alloying.
