摘要
Mn13钢铸件在铸后割冒口期间频频发生开裂现象。通过不同温度下的铸后去应力退火试验，发现去应力退火温度控制在400～450℃之间能有效降低该铸件的开裂倾向。
The fissuring often happens a lot on the steel Mnl3 casting during the period of cutting its head after casting. Through the stress relieve anneal test after casting at different temperatures, it is found that only the stress relieve anneal temperature be controlled within 400～450℃ could effectively reduce the fissuring trend of this casting.
