5-10min is arranged to, soaking time is set to 15-20min, and forging then is put into cyclic water tank again is cooled to room temperature, reaches
Grain refinement, and forging is heated into warming up treatment several times, the quenching treatment that cools down after heating is melted down by multiple high temp,
To improve the plasticity of forging, have the function that crystal grain thinning, to improve the plasticity of forging.
Preheated before step 5, smart car：Forging is placed into electric furnace and carries out being previously heated to 560 DEG C -580 DEG C, then will
Forging after heating carry out insulation 5-5.5 it is small when, then to coming out of the stove after less than 150 DEG C, cooling time is set as furnace cooling
1-2 it is small when, pass through the preheating before smart car, it is possible to increase further crystal grain is refined, can ensure smart car processing
When forging can not become, ensure smart car when forging precision.
Step 6, smart car processing：Final step smart car processing is carried out to the forging after forging, by smart car can will half into
The blank of product carries out smart car processing, to complete the processing of forging.
Preferably, the material of the smearing protective layer in the step 1 is CVD coatings, can by using this coating
Preferably reduce the generation of decarburized layer.
Preferably, preheating temperature when being preheated before the smart car in the step 5 is set to the ceiling temperature of preheating temperature, this
Using 580 DEG C in process, and tapping temperature is set to 120 DEG C, and forging can more be filled by carrying out high temperature preheating
The preheating divided, makes the effect of preheating reach best.
Preferably, the finish forge processing in the step 4 is divided into finish forge three times, carries out heating for multiple times to forging and water tank is cold
But handling, the temperature of wherein heating and thermal insulation reduces step by step, and respectively 1100 DEG C, 1050 DEG C, 1000 DEG C.Soaking time subtracts step by step
It is few, and respectively 20min, 18min, 15min, by multiple finish forge, and the finish forge processing that cools down step by step is carried out, can be more abundant
Finish forge processing is carried out to forging, and becoming larger in forging process crystal grain can be preferably reduced, to influence horizontal plasticity.
Preferably, heating and heat-retaining condition when the finish forge in the step 4 is handled are vacuum environment, in vacuum environment
Under when can make heating and air exclusion, reduce the forging when heating and aoxidized with air, to influence the forging of forging
Effect.
The beneficial effects of the invention are as follows：
1), by carrying out stabilization processes to the stability of forging process, to reduce forging ratio, crystal grain is carried out at refinement
Reason.
2) mechanical performance of forging, is improved, the opposite sex is reduced and occurs, improve the stability of forging, improve forging quality.
Embodiment
In order to make those skilled in the art more fully understand technical scheme, the present invention will be made into one below
Step is discussed in detail.
A kind of stabilizing treatment technique of forging process, the process of its stabilizing treatment technique are：
Step 1, protective coating are smeared：The forging forged before processing to needs is smeared, before heating in forging
Protective layer is uniformly smeared on surface, is smeared by protective layer before being forged to forging, so as to reducing the table of forging when forging
Face carbonization situation produces.
Preheating before step 2, forging：Forging is placed into electric furnace and carries out being previously heated to 380 DEG C, then by after heating
Forging carry out insulation 2.5 it is small when, by the preheating before forging can enable forging forging when carry out high temperature forging when more
Carry out moulding processing in short time, make forging easier.
Step 3, forging process for fuel：By forging equipment by after METAL HEATING PROCESS, forging molding is carried out, by metal according to corresponding
It is required that forging is forged.
Step 4, finish forge processing：Forging is kept the temperature into stove heat to 1100 DEG C immediately after forging, and heating time is arranged to
10min, soaking time are set to 0min, and forging then is put into cyclic water tank again is cooled to room temperature, reaches Grain refinement, and
And forging is heated into warming up treatment several times, and cool down quenching treatment after melting down heating by multiple high temp, can with improve forging
Plasticity, has the function that crystal grain thinning, to improve the plasticity of forging.
Preheated before step 5, smart car：Forging is placed into electric furnace and carries out being previously heated to 580 DEG C, then by after heating
