摘要
Q345D钢在生产时普遍存在低温冲击功偏低的问题,通过调整钢液化学成分,适当降低锻造加热温度及终锻温度,加强正火效果,使Q345D锻件低温冲击功完全满足技术协议要求。
Q345D steel production is pervasive low-temperature impact energy,by adjusting the chemical composition of molten steel,appropriately lower forging temperature and final forging temperature,strengthen the normalizing effect,Q345D low temperature impact energy of forgings satisfying technical agreements.
