热锻模失效的主要原因是复杂的热力和摩擦载荷导致的磨损。通过热化学表面处理和小规模锻造，可以提高刀具寿命。然而，这两种工艺都会导致模具表面温度升高。通过强化冷却降低模具表面的热负荷，可以大大减少结构的损坏，从而减少模具的磨损。

Hot forging dies fail mainly because of wear as a result of the complex thermomechanical and tribological loading. An increase in tool life can be achieved through thermochemical surface treatment and forging with little scale. Both processes, however, lead to an increase of the die surface temperature. The lowering of the thermal load of the die surfaces by intensive cooling reduces the damage of structure and therefore the wear of the dies considerably.
