Description

Technical Field

[0001] The utility model relates to the technical field of smelting furnaces, in particular to an intermediate frequency induction smelting furnace with a rapid cooling effect. Background Art

[0002] The basic principle of an intermediate frequency induction smelting furnace is to use the principle of electromagnetic induction for heating. When high-frequency alternating current passes through the induction coil, an alternating magnetic field will be generated. When the metal material enters this magnetic field, eddy currents will be generated. The eddy currents generate a reaction force that hinders the passage of current inside the metal, thereby heating the metal material. Since the resistivity of the metal is relatively large, the eddy currents are mainly concentrated on the metal surface, so the heating effect is better. The intermediate frequency induction smelting furnace uses intermediate frequency alternating current power generation, does not generate noise, and has large vibrations; the movement of gas can be realized by using the magnetic resistance effect of the intermediate frequency electromagnetic field in the air, generating magnetic field energy, and has a good control effect. Since no high-temperature molten slag is generated, materials such as steel and aluminum can be processed into products of various shapes and sizes.

[0003] In the patent document with the publication number CN218955466U that has been made public, an intermediate frequency induction smelting furnace convenient for heat dissipation is disclosed, which includes a housing placed on the ground, a base placed on the inner side wall of the bottom of the housing, a furnace lining placed above the base, an induction coil arranged on the outer side wall of the furnace lining, and a yoke placed on the outer side wall of the induction coil. There is a certain gap between the yoke and the inner side wall of the housing. It also includes a temperature reduction component, and the temperature reduction component includes a heat exchange part, a first air duct, and a second air duct. The heat exchange part is located above the housing. The intake end of the first air duct penetrates the side wall of the top of the housing, and the outlet end of the first air duct penetrates the side wall of the bottom of the heat exchange part. The intake end of the second air duct penetrates the side wall of the top of the heat exchange part, and the outlet end of the second air duct penetrates the side wall of the bottom of the housing and is connected. The inner side wall of the housing is spirally provided with guide vanes. This application has the effect of reducing the temperature of the yoke during operation.

[0004] After the furnace lining of the intermediate frequency induction smelting furnace is damaged, it needs to be replaced in time. During the process of disassembling the furnace lining of the existing intermediate frequency induction smelting furnace, the furnace shell is easily damaged, and the process of disassembling and assembling the furnace lining is relatively cumbersome and laborious, resulting in a long time-consuming process for replacing the furnace lining, which affects the working efficiency of the intermediate frequency induction smelting furnace.
