Background technology
Heavy casting and forging industry is a very special industry, and development level is to weigh a national overall national strength
One of mark.Heavy casting and forging product is electric power, metallurgy, petrochemical industry, shipbuilding, railway, mine, aerospace, military project and engineering etc.
The basic components of equipment are the bases of major equipment manufacturing industry, are related to national security and lifelines of the national economy.
Since the original steel ingot of large forgings is usually to cast, and the metallurgical quality of steel and coagulating property can not be kept away
Many genetic defects, common defect can be brought to have to steel ingot with exempting from：Be segregated, be mingled with, gas, bubble, shrinkage cavity, loose, crackle
With splash scar.The formation and smelting of these defects, the processes such as casting and cooling are closely related, and steel ingot is bigger, and defect is more serious,
These defects also tend to be to considerably reduce the billet yield of steel ingot the main reason for causing large forgings to scrap；And steel ingot
Internal defect is not visible, these defects also are difficult to eliminate by the improvement of smelting process.In traditional forging process,
The riser and ingot tail of steel ingot are more due to existing defect, it usually needs excision so that the utilization rate of material reduces, and the energy disappears
Consumption increases.

It is proposed on this basis include it is axial pre-upset, radial direction jumping-up and etc. forging method.Pass through the multiple upsetting before forging steel
Pull out forging process so that steel etc. tropisms and transverse and longitudinal structural homogenity be improved, steel are not dropped in longitudinal performance
Lateral performance increases while low, since upsetting pull of every completion melts down heating and thermal insulation, melts down and realizes that upsetting pull base is replied
Recrystallization, the pier be conducive to next time pull out forging and crystal grain refinement.But such methods to destroy metallic continuity, cause it is micro-
Crackle, reduce forgeability and forging after mechanical property out-phase particle class be mingled with and steel ingot in survival gas (such as oxygen, nitrogen,
Hydrogen etc.) finally with oxide and nitride form, formed in steel ingot cause steel plasticity reduce forging inside white point and
The defects of hydrogen embrittlement, can not play the role of effectively eliminating, therefore lack adaptability to the stringent forging of quality requirement.
And " dissimilar metal constructs manufacturing process " of Publication No. CN105499459A, it discloses a kind of dissimilar metal and constructs
Manufacturing process, including prepare at least one first primitive and multiple second bases made of the second material made of the first material
Multiple primitives are stacked to predetermined shape, the multiple primitives for being stacked to predetermined shape are packaged into pre- by multiple primitives that member is constituted
Base, then interfacial weld between multiple primitives is made so that blank is made in prefabricated blank by smithwelding.The manufacturing process
The middle process for preparing primitive is only simply described as " being specified size by polylith small dimension metal base blanking ", and there is no specific
The determination foundation and mode of primitive sectional dimension are introduced, it is relatively more general, it is unfavorable for the implementation of method.The manufacturing process is to prefabricated blank
It is identical as the mode of heating of common steel ingot to implement the mode heated before forging, but due to the prefabricated blank Jing Guo smithwelding, does not have after welding
There is carry out stress relief annealing, so easily causing the deformation of commissure by common heating mode, influences dissimilar metal following process
Quality.Also, the step of jumping-up and smithwelding of prefabricated blank implementation, is described in the manufacturing process, is also only simply described
The pushing deflection of jumping-up, without reference to temperature, soaking time and welding in upsetting process than the relationship between pressure, it is difficult to realize
The abundant soldering of multiple primitive underbead cracks, cannot completely eliminate the void-type defect of primitive, therefore cannot be satisfied homogenous metal class
The forging quality requirement of large forgings.
Since misoperation or note speed, casting temperature control system are improper during ingot casting so that exist inside the steel ingot cast cavity,
The defects of crackle, segregation and the second phase.These defects generally existing in steel ingot manufacturing process, and steel ingot is bigger, steel ingot
Internal metallurgical quality gets over Customers ' Legal Right；Moreover, a lot of defects are not visible, and it is unpredictable, it is difficult to eliminate by simply forging.At present
80% or more the large forgings that the country is scrapped is caused by ingot quality is unqualified.Especially as the master of hydroelectric generation
Forging shaft, mechanical property requirements are more stringent.Therefore it is necessary to the forging methods to existing large forgings to be improved.

Specific implementation mode
According to Fig. 1~5 specific steps that the present invention will be described in detail.The folded forging production main shaft forging of the multiple-unit homogenous metal
Method includes：
Step 1 calculates dependent variable and temperature needed for soldering to select the rolled slab of suitable dimension according to material
Etc. factors influence, to determine the sectional dimension of slab cell cube.
According to the peaceful variation issue for waiting the cavernous defect of heavy forging of researchs in plastic processing of gold, using mathematical solution
The technique study of analysis pressing mechanism, condition and criterion of the heavy forging interior void defect in plastic processing, with sky
Based on the mechanics of hole, be deduced pressing heavy forging interior void defect criterion, and according to result of study inquired into FM methods,
Closure rule, closed path and the closing speed in heavy forging inner cylindrical cavity in WHF methods and V-type anvil forging technology.With porous
It is derived from based on the theory of plasticity of compressible material and empty mechanics, it is macro inside forging stock in the production process of heavy forging
Seeing the closure condition lacked with microscopic holes type can be expressed as：
In formula：γs--- octahedral shear strain
V0--- original voidage
Wherein,
The area that can determine cavity according to above formula, the sectional dimension of slab cell cube is determined according to cyst areas, is selected

Shape amount is also minimum；Laser beam can focus on the region of very little, be suitable for the smaller component of weld interval, and can reduce slab weldering
The use for connecing the required time, even saving filler metal.
Step 4 lifts integrally welded stacking slab cell cube, so that it is lain on the parallels of heating furnace, cell cube
Welding surface be parallel to horizontal plane arrangement.The heating process curve of the slab cell cube of stacking and the heating curves phase of common steel ingot
Than the soaking time of low-temperature zone, middle warm forging and high temperature section is all opposite to extend.It is moved back without destressing after being welded due to built-up welding slab
Fire, to prevent welding stress from commissure being caused to deform, so the soaking time of middle-temperature section is appropriately extended.When high temperature section is kept the temperature,
The soaking time of cell cube heap weldment can not calculate heating time according to the size of single-piece smallest cross-sectional size, but will be according to
More than one piece blank stacking direction size calculates heating time, and soaking time keeps the temperature 1.5 hours according to every 100mm and calculates.
Due to the internal stress of the stacking slab cell cube of laser beam to be eliminated fusion welding, the slab cell cube of stacking adds
Thermal process curve is compared with the heating curves of common steel ingot, 1.3 times of the holding time of low-temperature zone, middle-temperature section and high temperature section.
Specifically heating process is：It first, will be warm with the heating rate less than or equal to 50 DEG C/h after keeping the temperature 10 hours at 350 DEG C
Degree is increased to 750 DEG C, then keeps the temperature 7 hours at 750 DEG C, then with the heating rate less than or equal to 50 DEG C/h by temperature liter
Height is to 1080 DEG C, and after keeping the temperature 12 hours at 1080 DEG C, according to heating furnace automatic heating power (improving heating power) quickly
1220 DEG C are warming up to, finally 20 hours is kept the temperature at 1220 DEG C, completes entire heating process.
Step 5 carries out upset pressurize soldering to the stacking slab cell cube after heating.With iron chains the stacking after heating
Slab cell cube is hung on the upset platform of hydraulic press, in lifting elements body, to be always ensured that the welding surface of cell cube is parallel
In horizontal plane.Upset pressurize soldering is the key that the present invention, and the crack type defect of slab cell cube is in temperature, soaking time and weldering
When connecing than pressing three to meet Fick's second law, sufficient soldering can be realized.Fick's second law is the base in First Law
It is derived on plinth, Fick's second law is pointed out, during Unsteady Casting, at distance x, concentration changes with time
RateEqual to the diffusion flux at this with range rateNegative value, i.e.,
It willAbove formula is substituted into, is obtained
In formula：T --- diffusion time (s)
Volumetric concentration (the kg/m of C --- diffusate3)
X --- distance (m)
In fact, the diffusion coefficient D of Solute Atoms In Solid Solution is changed with concentration, in order to keep solution diffusion equation simple
It is single, often approximatively D is treated as constant.According to the crackle of Fick's second law slab cell cube in upset pressurize
During soldering, by stages such as Crack blunting, crackle merogenesis, schizocele nodularization, cavity healing and uniform qualities, it is finally completed
Healing.
It is several that Crack Healing Process is divided into Crack blunting, crackle merogenesis, schizocele nodularization, cavity healing and uniform quality etc.
Stage.For upset slab cell cube in place, according to welding than pressure (dwell pressure of press), the welding in crack
The difference of time (dwell time) and material, optimal parameter are also not quite similar.When the material of main shaft forging is 20SiMn,
By calculating, the best welding temperature of the material is 1100~1150 DEG C, and welding is 5~10MPa than pressure, weld interval is 30~
60min。
The soaking time of step 6, High temperature diffusion is also extremely important to soldering process.In same deflection and heat preservation temperature
Under the conditions of degree, extension soaking time appropriate can improve soldering effect.The soldering of crack type defect is by atoms permeating etc.
What mechanism was realized, the average distance that atoms permeating is passed by is directly proportional to the square root of diffusion time.General satisfaction following formula：
In formula：The average distance of X --- atom
τ --- soaking time
K --- constant, related with material, general steel alloy is 1.5
According to calculating, when the High temperature diffusion soaking time for stacking slab cell cube main shaft forging is general steel ingot forging heat preservation
Between 1.5~1.7 times.General carbon steel and low alloy steel steel ingot soaking time is usually calculated according to the speed of 100mm/h.
