Abstract
The hardening ceramic processing method for surface of piston rod includes the steps of forging, normalizing, coarse machining, seasoning, semi-finishing, stress-eliminating tempering, coarse grinding, spraying ceramic and finishing. Compared with conventional production process, the present invention has reduced hot processing time, lowered rejected product rate, and greatly increased piston rod life.
Description
[technical field]
Piston rod is a vital part on the reciprocating compressor, and it plays a part transmission power and cooperates the packing seal medium in compressor, in industries such as petrochemical industry, chemical fertilizer, the safe and reliable operation of producing is played important effect.The hardening ceramic processing method for surface of a kind of reciprocating compressor piston rod that comes to this that the present invention relates to.
[background technique]
The diameter difference of its piston rod of compressor of different sizes, the load of being born are also different, to tens of ton forces, and bear tension and compression and the alternate load that produces from tens kgfs, thereby require it to have good mechanical properties.
Piston rod not only bears alternate load at work, but also will match with filler, the medium that has certain pressure in the sealing cylinder, the pressure of medium is from several MPa to tens MPa, filler is friction mutually on piston rod surface, thereby requires piston rod to have good wear resistance.
Piston rod also will contact with Korrosionsmedium in a lot of occasions, as: carbon dioxide, hydrogen sulfide, ammonia, chlorine etc., this just requires piston rod that good corrosion resistance will be arranged.
At present, the processing and fabricating situation of piston rod is:
1, material aspect
Piston rod generally adopts 45 under no etching condition
#, 42CrMo, 38CrMoAL make; Under the general corrosion condition, adopt 2Cr13,3Cr13 makes; Under the heavy corrosion condition, adopt oCr17Ni4Cu4Nb (import stainless steel).Its course of working of various different materials is different.
2, manufacturing process
45
#, 42CrMo material piston rod machining process:
Forging → normalizing → roughing → modified → semi finishing → de-stress temper → corase grind → high frequency hardening → pressure straightening → low-temperature tempering → correct grinding.
2Cr13,3Cr13 material piston rod machining process:
Forging → annealing → roughing → modified → semi finishing → de-stress temper → corase grind → high frequency hardening → pressure straightening → low-temperature tempering → correct grinding.
38CrMoAL material piston rod machining process:
Forging → normalizing → roughing → modified → semi finishing → nitrogenize heat treatment → alignment → low-temperature tempering → correct grinding.
OCr17Ni4Cu4Nb material piston rod machining process:
Forging → solution heat treatment → adjustment heat treatment → roughing → timeliness heat release processing → semi finishing → de-stress temper → high frequency hardening → semi finishing → timeliness heat treatment → alignment → tempering → fine finishing.
The sort of material all will be through the operation of tens road cold and hot workings, and the manufacture cycle of piston rod is long, the expense height, and accepted product percentage is low.
[summary of the invention]
The object of the present invention is to provide a kind of hardening ceramic processing method for surface of piston rod, adopt ceramic cure process not only can reduce the activity time of piston rod, and, make the piston rod material obtain certain unification because pottery is a resistant material.
Manufacturing process provided by the present invention is:
Forging → normalizing → roughing → modified → semi finishing → de-stress temper → corase grind → ceramic spraying → fine finishing.
Ceramic spraying has replaced the high frequency hardening (or nitriding treatment) in the processing in the past, pressure straightening, and the low-temperature tempering process has significantly reduced the working time.
Produce piston rod with this method, not only the cycle lacks, and the anticorrosion antiwear of piston rod is good.
[embodiment]
The detailed process of ceramic spraying:
After the modified semi finishing of piston rod, piston rod oil removal treatment (i.e. the piston rod surface that will spray) with alkaline cleaning, then:
1, piston rod carries out shot blast: with 22 order emery piston rod is carried out shot-peening, the nozzle back pressure is wanted 〉=0.6MPa
2, with the plasma spraying machine spraying that feels secure:
Adopt GP formula spraying machine, jet velocity 600m/S, operating temperature＜800 ℃, granularity 200-320 order, sprayed on material Ni, AL proportion of powder are 95: 5.
3, carry out ceramic spraying with plasma spraying machine:
Adopt GP formula spraying machine, jet velocity 600m/S, particle size 20-40m, powder temperature＞184 ℃, proportion of powder (%) AL
2O
3: 60, TiO
2: 40, or TiO
2: 13, AL
2O
3: 87; Or TiO
2: 100; Or AL
2O
3: 94, TiO
2: 2.5, SiO
2: 3.5.Coating is 5m at every turn.
4, piston rod correct grinding:
Adopt diamond wheel, on outer circular end grinding machine, each depth of cut storehouse 5m.
5, sealing of hole
Piston rod was soaked in cyclochloride resin 1 hour.
Behind the piston rod processed finished products, be black, the surface is glossy, hardness 〉=HRC60.
Adopting pottery to handle significantly reduces the heat processing technique time, reduced reject rate, and because wear resistance, the corrosion resistance of pottery itself, the piston rod life-span is greatly improved, in the actual examination of Fujian oil refinery, Luoyang refinery, Shijiazhuang Oil Refinery, Tianjin oil refinery, assert that tentatively be three times of past piston rod its working life now.
