Embodiment two：
Referring to Fig. 6, a kind of gear sheet heat treatment process, including step S1：Shove charge step wears gear sheet and gasket interval
It is hung on iron staff, then prepares several pallets, be fitted into after iron staff being placed in one by one on pallet into heating furnace；Until pallet is complete
Portion is put into in heating furnace and after fixing, and enters back into step S2：Heating stepses heat heating furnace, so that heating furnace exists
It is disposably warming up to 850-870 DEG C, preferably 860 DEG C in 20min, continues gear sheet in the environment of 850-870 DEG C
2.5h-4.5h。
Step S3：Carburization step is added dropwise ethyl alcohol towards the gear sheet in heating furnace and is filled with methane gas, to improve gear
The phosphorus content of piece, enhances the surface hardness of gear sheet, and ethyl alcohol is added dropwise and is filled with the concrete operations of methane gas in the following way,
It is firstly because gear sheet to need to continue 2.5h-4.5h in the environment of 850-870 DEG C, therefore in this process, carburizing institute
The time needed is 20-30min；And in order to guarantee that carbon can be fully dissolved in into gear sheet, in the mistake of entire gear sheet heat preservation
Carburizing needs to carry out in two times in journey, and time of first time carburizing is in the 2.5h-4h in insulating process, and instills ethyl alcohol
Time and the entire time for being filled with propane are 20min, account for the 2/3 of total time；The time of second of carburizing is in insulating process
It in 4h-4.5h, and instills the time of ethyl alcohol and is filled with the entire time of propane as 10min, account for the 1/3 of total time.
In addition, before carburization, and need to guarantee that carbon incorporates the efficiency into gear sheet, it can be step by step S3 points
Rapid S31 and step S32, step S31 are that ready denier oil acid is dissolved in the ethyl alcohol of dropwise addition, and ethyl alcohol and ready denier oil acid
Mass ratio be 50:1；Step S32 is controlled the additional amount of ethyl alcohol and methane, and specifically referring to will be dissolved with Carvedilol grease
The ethyl alcohol of fat acid is added with the amount of 7-8L/min to heating furnace with 45-55mL/min, propane.
The test table of 1 output shaft carburizing efficiency of table
Step S4：Gear sheet after carburizing is put into the cooling oil for being 50 DEG C -60 DEG C to oil temperature and carries out fastly by quenching Step
But, wherein cooling oil used in quenching is located in oil groove, and the bottom of oil groove is provided with using driving motor band quickly cooling
The pallet for being placed with gear sheet can be placed on turntable by the turntable of dynamic rotation, when quenching, restart driving motor, so that driving electricity
Machine drives pallet rotation to be stirred to cooling oil, to accelerate quenching velocity, the oil of final gear sheet cooling oil after quenching
Temperature can rise to 120 DEG C -130 DEG C；After quenching, more cooling oil can be sticked in gear sheet, for the waste for reducing cooling oil, support
Gear sheet on disk after the cooling oil in oil groove is cooling, pallet can be taken out out of oil groove and hang in heating furnace into
Row drains 10-20min, so that the cooling oil in gear sheet returns in oil groove.
Step S5：Gear sheet is pulled out and is cleaned from heating furnace by cleaning step, to remove the cold of gear sheet surface
Oily；Cleaning agent used in cleaning in this process is that non-phosphor degreaser powder is added in water to be formed, and non-phosphor degreaser
The volume ratio of powder and water is 1:16.
Step S6：Gear sheet is reheated to 170 DEG C -300 DEG C by tempering step in 2h-4h；Step S7：By gear
After piece stands natural cooling, gear sheet and gasket are separated with separator.
The above is only exemplary embodiment of the invention, protection scope and is not intended to limit the present invention, this hair
Bright protection scope is determined by the attached claims.
