Preferably, step b spraying overcoat before by the first mould cylinder and the second mould cylinder be heated to 200 DEG C and keep 800 turns/
The rotating speed of min, the overcoat are zircon sand interlayer, stop operating and the first mould cylinder and the second mould cylinder put after the completion of spraying
1h is incubated at 300 DEG C.
Preferably, the rotating speed during centrifugal casting of step c, e is 750-850 turn/min.
Preferably, need for copper alloy to be heated to 1300 DEG C -1500 DEG C before step e spun casting outer layer, and keep this temperature
Degree.
Preferably, the time of step e spun casting outer layer is 10min.
Preferably, in step f, rotating speed is 350 turns/min and keeps 10min.
Compared with prior art, the invention has the advantages that：1. bimetal centrifugal is realized using special mould cylinder
The preparation of casting copper covered steel, process is simple, lumber recovery are high, practical；2., because of the low cost of cast iron, one is wrapped up in Cast Iron Surface
Layer copper alloy, after two kinds of metals are combined, the workpiece gear of gained, not only cost is lower, and impact resistance is more preferable.
