Method for delaying oxidation of tin mold by spraying graphite

The invention discloses a method for delaying oxidation of a tin mold by spraying graphite, which is characterized in that graphite and graphite flux are uniformly mixed and then uniformly sprayed on the inner side of the tin mold, the mass ratio of the graphite to the graphite flux is (3-4): (1-2), and the spraying thickness is 0.8-1mm. According to the method, graphite is sprayed on the surface of the tin mold, operation is easy, the inner side of the tin mold can be prevented from making direct contact with oxygen, and the inner side of the tin mold can be prevented from making contact with water in the water cooling process; the oxidation and corrosion speed of the tin mold is delayed, the service life of the tin mold is prolonged, the tin refining operation cost is reduced, the situation that rust and other impurities enter tin ingots to affect the product quality can be greatly reduced, and the economic index of the tin refining technology is improved. 本发明公开了一种喷涂石墨延缓锡模氧化的方法，所述方法为将石墨和石墨熔剂混合均匀后，均匀喷涂在锡模内侧，
