Hour, after be warming up to 1100 DEG C, soaking time was controlled at 2 hours, then carried out hot rolling, 11 passage of hot rolling, first mill train to blanket
Secondary opposite reduction ratio 8%, other passages are controlled with respect to reduction ratio in 10-15%, and mill speed is controlled in 50mm/s, finishing temperature
At 820 DEG C；Plate thickness 2mm is air-cooled to room temperature after rolling,
Punching press：Plate is heated to 800 DEG C of progress punching presses, room temperature is air-cooled to, obtains oil pan body,
Heat treatment：Oil pan body be heated to 750 DEG C keep the temperature 3 hours, after quenched, hardening media is water, after quenching again
Be heated to 500 DEG C and keep the temperature 3 hours, after be cooled to 350 DEG C, 60 DEG C/h of rate of temperature fall, keep the temperature 2 hours, after be cooled to again
250 DEG C, 50 DEG C/h of rate of temperature fall, keep the temperature 3 hours, after be air-cooled to room temperature,
Sandblasting roughening：Sandblasting roughening treatment is carried out to the inner surface and the outer surface of groove body trapezoidal in oil pan body, sand grains is stone
Sand, the size of sand grains are 20 mesh, and blasting pressure 0.4MPa, sand-blasting gun is 40mm away from workpiece distance, empty with compression after sandblasting
Air-blowing is net；
Inner surface coating：Coating alumina system coating is carried out to oil sump groove body inner surface；By being coated in oil sump groove body
Surface forms alumina series coating, and aluminum oxide based materials layer includes（Weight）：70-80 parts of aluminium oxide, 20-30 parts of tungsten carbide, oxygen
Change zirconium 10-20 parts, the oil sump after coating heated, is warming up to 650 DEG C, 25 DEG C/h of heating rate, keeps the temperature 4 hours,
After be cooled to 450 DEG C, 60 DEG C/h of rate of temperature fall, keep the temperature 3 hours, after be cooled to 300 DEG C again, 50 DEG C of rate of temperature fall/small
When, keep the temperature 5 hours, after be air-cooled to room temperature,
Outer surface coating：Coating epoxy modified silicone resin coating is carried out to oil sump groove body outer surface, the coating includes
（Weight）：80-90 parts of organic siliconresin, 10-15 parts of sodium metasilicate, 10-15 parts of glass powder, 7 parts of talcum powder, 4 parts of ethylenediamine, chlorination
4 parts of magnesium, 5 parts of trbasic zinc phosphate, 3 parts of Polymethacrylimide, obtain final oil sump.
