摘要
本文通过对冷作模具钢X45NiCrMo4锻制扁钢退火工艺的研究和改进，获得了符合标准退火硬度值的金相组织，并运用于大生产实践，取得了满意的效果。
Annealing Technology of Forged Flat steel Bar for Cold-Working Die SteelX45NiCrMo4 has been studied and improved upon. Thus the metallographic structure whichaccords with standard annealed hardness is obtained. The mentioned annealing technologyhas been employed in mass production and achieved satisfactory results.
