| titleOfInvention | High manganese steel frog casting cavity coating spraying process |
| abstract | The invention discloses a high manganese steel frog casting cavity coating spraying process, which comprises the following steps: a. spraying: uniformly spraying the full-mold cavity once by adopting a coating; b. brushing: uniformly brushing the wheel rim groove once by hand from the toe end to the 50mm section of the center rail; c. surface treatment: brushing the wheel rim groove with a brush dipped with alcohol for one time; the coating adopted in the process comprises the following steps: the process can eliminate the waste casting defects caused by heavy skin, cold shut and the like in high manganese steel frog castings, can save about 15 wastes per month, and generates the economic value of 8 ten thousand yuan; the appearance of defective products of castings can be controlled, the sand sticking defects of the upper jaw part and the lower jaw part of the frog fish tail and the process pressure table part can be well controlled by the process, and the surface quality of the castings is greatly improved. And thirdly, the labor intensity of workers is greatly reduced, the overall surface quality of the casting produced by using the spraying process is very good, and a large amount of manual grinding is not needed. |
