摘　　要：12Cr1MoVG合金材料被广泛用于锅炉的蒸汽高压管道中,此合金材料的热处理方式对材料的综合性能起到关键作用,但利用现有的两种热处理方式不能很好地满足锅炉运行对于管道的要求,因此本文在“正火+回火”、“淬火+回火”2种方式基础之上,通过间歇淬火来控制回火后的冷却速率,保证材料组织中存在一定含量的铁素体和贝氏体,最终使得材料在强度、韧性和硬度方面均能达标。12Cr1MoVG alloy material is widely used in high-pressure steam pipe of boiler.The heat treatment method of this alloy material plays a key role in the comprehensive performance of the material,but the existing two heat treatment methods can not meet the requirements of boiler operation for the pipeline.Therefore,based on the two ways of"normalizing+tempering"and"quenching+tempering",this paper adopts intermittent heat treatment Quenching is used to control the cooling rate after tempering to ensure that there is a certain amount of ferrite and bainite in the structure of the material,and finally the strength,toughness and hardness of the material can reach the standard.
