Also providing for a kind of rotary compressor for refrigerant slide plate, slide plate material is carburizing steel, and the chemical composition of carburizing steel is such as Lower weight %:C0.17～0.24 Si0.17～0.37 Mn0.80～1.10 Cr 1.00～1.30 Ti 0.04～0.10 Fe Surplus.
The described hardness after carburizing steel heat treatment is 56-63HRC.
Accordingly providing the manufacture method of a kind of rotary compressor for refrigerant slide plate, it comprises the steps:
(1), select carburizing steel, be cold rolled to steel bar；
(2), the shape and size of the slide plate that processing steel bar is the most required；
(3), slide plate is carried out carburizing and quenching；
(4), the slide plate of carburizing and quenching is carried out cold treatment；
(5), again the slide plate after cold treatment is carried out temper；
(6), corase grind each face of slide plate；
(7), fine grinding each face of slide plate is to reaching regulation requirement.
As stated above, so that it may produce qualified rotary compressor for refrigerant slide plate.
Compared with prior art, it is an advantage of the current invention that:
1, raw material selects carburizing steel, its abundance of originating, and price is low, and cost saves.
2, having good processability due to carburizing steel, therefore processing cost is low.
3, slide plate is after carburizing and quenching, cold treatment, temper, its excellent performance, and the use fullying meet slide plate is wanted Ask.
