Sensor sends a signal to controller, and controller controls primary heater (13), 5-10min is kept the temperature, when temperature reaches 800-850 DEG C
When, carburizing solvent, and isothermal holding are separately added into quenching chamber (11)；
Step 2: needle roller Carburization Treatment
Needle roller is placed on conveyer belt, controller starts conveyer belt, and needle roller is transported in quenching chamber (11), and conveyer belt stops
Rotation；In the quenching chamber (11) of above-mentioned heat preservation after heating 0.5-1h, starts conveyer belt, needle roller is submerged in glowing furnace (14),
It is quenched；
Step 3: needle roller cleaning operation
Conveyer belt delivers into quenched needle roller in the rinse bath (22) of purge chamber (21), and conveyer belt stops operating, control
Device control starting liquid feeding pump and blender (23), rinse bath (22) is interior to be full of needle roller cleaning solution, inhales under stiring to needle roller surface
Attached quenching oil residue is cleaned, and the cleaning process is 5-10min, the starting secondary heater of controller control at this time
(33), reversing chamber (32) is warming up to 700 DEG C；
Step 4: needle roller tempering
After reversing chamber (32) temperature reaches 700 DEG C, controller starts conveyer belt, and needle roller is transported to reversing chamber (32), conveyer belt
It stops operating, after keeping this temperature 0.5-1h, stops heating, controller starts blower (31), is cooled to room temperature needle roller.
9. a kind of processing method of needle roller annealing device according to claim 8, it is characterised in that: in the step 1
Carburizing solvent be respectively alcohols and alkanes organic reagent, including methanol, propyl alcohol, propane and butane.
