(EN) The invention provides a metal material insulation device, including a box body and an upper cover. The box body includes an inner lining for containing metal materials, an outer shell and a vacuum chamber. The upper cover includes the outer cover, the inner cover and the upper cover hollow cavity channel formed between the outer cover and the inner cover. The upper cover is sealed and connected with the box body to form the first sealing space for holding metal materials and the second sealing space arranged around the first sealing space, which improves the thermal insulation performance of the metal materials stored in the first sealing space. Insulation method of the invention: The cooling rate of metal materials can be adjusted by controlling / adjusting the vacuum degree in the second sealing space, and the mechanical properties of metal materials can be improved. The installation labor intensity of the vacuum insulation layer is reduced by dividing the vacuum chamber into several small vacuum chambers and assembling them according to the needs. By controlling / adjusting the cooling medium in the second sealing space, the cooling rate of the liquid metal in the first sealing space is adjusted to improve the quality of the metal ingot.
