The content of sulphur and phosphorus should remain on below 0.15%.
Nitrogen content is 0.005-0.017%, and it compresses flake graphite and promotes perlite to form, and aluminium content be＜0.01%, plays graphite formation agent.
The grey cast iron alloy also comprises the iron and the normal impurity of surplus.Titanium, nitrogen and aluminium still can be through preferred in the normal impurities scope.
A kind of preferred grey cast iron alloy of the present invention comprises: the carbon of 3.3-3.4%, the silicon of 1.8-2.2%,＜0.1% sulphur,＜0.05% phosphorus, the manganese of 0.4-0.6%, the chromium of 0.2-0.4%, the molybdenum of 0.2-0.3% and the vanadium of 0.05-0.1%.
Oil engine casting engine parts of the present invention are engine body parts or cylinder head sub-assembly preferably.
Embodiment
The preparation 1500kg batch of material, each batch of material is cast into the engine body of 4 300kg, cast in begin under 1420 ℃ and in casting cycle temperature reduce about 10 ℃.
Use basic alloy, ten various combinations of preparation molybdenum, vanadium, titanium and niobium and batch of material.
And the content of nitrogen and aluminium forms agent (Inoculant) with different nuclear cores and changes in 16 different batch of materials.
Water the foundry goods from each and to extract the Fatigue Test sample and to carry out fatigue measurement.
Further, preparation have the optimum that shows said determination composition batch of material and carry out fatigue measurement.
The results are shown in Fig. 1, curve 3 is corresponding to the composition in compositing range of the present invention, and this composition also is presented at table 1.
