The invention relates to the technical field of vermicular graphite cast iron production, in particular to copper-chromium alloy vermicular graphite cast iron production equipment and process. The copper-chromium alloy vermicular graphite cast iron production equipment comprises a metal smelting furnace, a ladle, a ladle cover, a wire feeding machine and a limiting guide pipe, the wire feeding machine is installed on one side of the ladle, the ladle cover is buckled to an opening in the top of the ladle, and the limiting guide pipe is installed between the wire feeding machine and the limiting guide pipe. The limiting guide pipe is used for pouring the cored wire into the ladle through the wire feeder; according to the hot metal ladle, the hot metal ladle is divided into the outer ladle body and the inner ladle body, various kinds of high-temperature gas and smoke which are originally located in the gap between the liquid level and the ladle cover are collected in the heat storage cavity, the storage space of
