Description
Technical field
The present invention relates to metal material Field of Heat-treatment, more particularly to a kind of production technology of ring forging.
Background technology
At present, for using Q345D steel as raw material, wall thickness requires the ring forging in 90mm~120mm, using tune after forging
Matter processing, to cause its yield strength >=350MPa, and the Charpy-type test of V-notch is done at -20 DEG C, its ballistic work
Average value >=100J, so as to meet customer requirement.However, using modifier treatment after forging, not only processing cost is high, and production efficiency
Relatively low, thus, urgent need seeks a kind of new processing method.
The content of the invention
It is an object of the invention in view of the above-mentioned problems, a kind of production technology of ring forging is provided, to solve existing ring forging
Use modifier treatment after part forging, processing cost height, the problem of low production efficiency.

A kind of production technology of ring forging, it is raw material from Q345D steel, raw material is forged to obtain ring forging, in addition to
Lower step：
A, ring forging is heated to 1200 DEG C~1240 DEG C, is incubated 2h；
B, after insulation terminates, ring forging is taken out, pulled out, deflection is 50%~55%, then carries out jumping-up,
Deflection is 60%~65%, and whole deformation temperature control is at 1000 DEG C~1050 DEG C；
C, the size needed for ring rolls carries out rolling ring to ring forging, deflection are 40%~50%, whole deformation temperature control
At 850 DEG C~900 DEG C, the wall thickness of ring forging is 90mm~120mm；
D, it is air-cooled to room temperature.
As a preferred embodiment of the present invention, ring forging is put into heating furnace in step a and heated.
As a preferred embodiment of the present invention, pulled out in step b using Single arm, pier is carried out using Single arm
Slightly.
Whole deformation temperature in above-mentioned steps b is pulling, the temperature of upset ring forging later, thus, pulling, upset efficiency
Will height, with ensure ring forging will not it is cold fall.
Whole deformation temperature in above-mentioned steps c is the temperature of ring forging after rolling ring, and thus, rolling ring efficiency is high, to ensure
Ring forging will not it is cold fall.
Beneficial effects of the present invention are that ring forging is heated to 1200 DEG C~1240 by a kind of production technology of ring forging
DEG C, and be incubated after 2h and pulled out, upset, rolling ring, room temperature is finally air-cooled to, it is pulled out, upset, rolling ring is entered in same fire time
OK, and by control pulling deflection, upset deflection, rolling ring deflection, and by control pulling, it is upset after temperature
Temperature after degree and rolling ring so that the yield strength for the ring forging produced reaches more than 360MPa, and ring forging is at -20 DEG C
Under do the Charpy-type test of V-notch, the average value of its ballistic work reaches more than 120J.
