Description

Technical Field

[0001] The utility model relates to the technical field of insulation furnace protection, in particular to a insulation furnace protection device. Background Art

[0002] A holding furnace is an industrial furnace primarily used to insulate molten metal to maintain it within the casting temperature range, ensuring stable continuous or semi-continuous casting processes. The design power of a holding furnace is typically lower than that of a smelting furnace because its primary function is to compensate for heat loss, rather than performing large-scale smelting operations. Existing holding furnaces lack protective protection during use. This not only causes heat loss but also can cause burns if workers accidentally touch the furnace during operation, compromising work safety.

[0003] According to the description of a liquid aluminum holding furnace safety protection device published on the patent website (authorization announcement number: CN214276493U), the liquid aluminum holding furnace safety protection device includes "furnace cover, shell, limit holes", etc. to perform protection work.

[0004] In view of the above description, the applicant believes that the following problems exist:

[0005] The safety protection device of the liquid aluminum holding furnace utilizes a furnace cover, a shell, a limiting hole, etc. to perform protection work. During use, this device can only protect the top of the holding furnace through the furnace cover, and cannot protect the periphery of the holding furnace. When the staff accidentally touches the holding furnace during work, it will cause burns to the staff, and at the same time will cause the heat of the holding furnace to be lost, affecting the insulation effect. Therefore, this device needs to be improved. Utility Model Content
