Process for producing high toughness vermicular cast iron scroll plate

Abstract

The application discloses a high-toughness vermicular cast iron scroll disc process and relates to the technical field of scroll disc processes. In order to solve the problem that the existing process can cause the insulating riser to be inclined, the surface of the casting to be concave and loose due to the failure of feeding, impurities to be easily brought into the inner cavity of the casting, and the high waste of the casting machining material, the high-toughness vermicular cast iron scroll disc process comprises the following steps: S1, smelting molten iron by means of a smelting furnace, and transporting the molten iron to a wire feeding station when the molten iron reaches the requirement; S3, molten iron pouring after the wire feeding is completed; S4, the molten iron is poured into a mold cavity through a pouring cup and a riser to form a casting; S5, after the pouring is completed, the mold is opened after cooling on a cooling line; S6, cooling and separation are carried out after the mold is opened; and finally, polishing is carried out. The high-toughness vermicular cast iron scroll disc process has good roughness and guarantees the finished product effect of the casting. Moreover, the hot riser process is adopted, so that the cost is saved and the feeding effect is achieved.
