Beschreibung
Zusammenfassung:	The utility model discloses a furnace mouth device of an intermediate frequency furnace, which solves the problem that the intermediate frequency furnace in the prior art is not provided with a furnace cover integrating heat preservation, splash prevention and flue gas emission. The intermediate frequency furnace comprises an intermediate frequency furnace and a furnace cover arranged on the intermediate frequency furnace, and further comprises a crank mechanism and a heat preservation anti-expansion mechanism, a through hole is formed in the furnace cover, one end of the crank mechanism penetrates through the through hole to be connected with the heat preservation anti-expansion mechanism, a supporting rod is arranged on the upper portion of the intermediate frequency furnace, and the other end of the crank mechanism is connected with the supporting rod through a rotating hinge mechanism. A heat preservation and expansion prevention mechanism is arranged below the furnace cover, heat preservation in the heat
