锻件在锻打成形后,立即在高温奥氏体状态下进行淬火冷却,随后给予高温回火,用以代替一般采用的锻后置冷→淬火→高温回火的工艺,这就是所谓“锻热淬火”。它把锻造与热处理有机地结合成为一个完正的工艺过程。从热处理角度来看,它是属于高温奥氏体的形变热处理。 锻热淬火由于其对工件的强韧化作用正在得到日益广泛的应用。国内不少工厂已用于生产,大量的发动机中小型锻件(如连杆、齿轮等)正在用户受到运转的考验。实践 Forging in forging, immediately after the austenitic high temperature quenching, followed by high temperature tempering, instead of the commonly used forging after the cold → quenching → high temperature tempering process, which is the so-called “forging heat Quenching. ” It combines forging and heat treatment into a perfect process. From the heat treatment point of view, it belongs to the high temperature austenite deformation heat treatment. Forging heat quenching because of its role in the toughening of the workpiece is being increasingly widely used. Many domestic factories have been used for production, a large number of small and medium-sized engine forgings (such as connecting rods, gears, etc.) are being run by the user test. practice
