    Electric furnace principle
        

    Induction melting furnace is a melting furnace that uses the principle of electromagnetic induction to heat the metal placed in the inner cavity of its own furnace . The conventional induction melting furnace generally includes a furnace body component and a furnace bottom located at the lower part of the furnace body component. The furnace bottom is composed of multiple refractory bricks. During the process of smelting metal, the working conditions of the furnace bottom are generally very harsh. Withstand high temperatures above 1600 degrees Celsius, and the high temperature lasts for a long time. After the metal is smelted, this high temperature will drop sharply. When the next time the metal is smelted, the furnace bottom must repeat the high temperature and rapid temperature drop process. In other words, the temperature of the furnace bottom is suddenly cold and hot, which can easily cause the furnace bottom to crack.

    The technical problem to be solved by the utility model is to provide an induction melting furnace that can reduce the maximum temperature to which the furnace bottom is subjected when smelting metal, and can slowly reduce the temperature of the furnace bottom after the metal is smelted, thereby avoiding cracking of the furnace bottom. . The technical solution of the utility model is to provide an induction melting furnace having the following structure : including a furnace body component and a furnace bottom located at the bottom of the furnace body component, wherein the furnace bottom is made of a refractory material as a whole, and the interior of the furnace bottom is provided with Cooling pipes for cooling water. After adopting the above structure, compared with the prior art, the utility model induction melting furnace has the following advantages: Unlike the prior art furnace bottom, which is composed of multiple refractory bricks, the furnace bottom of the utility model induction melting furnace is made of refractory materials. It is a whole, and the cooling bottom can be provided with cooling water pipes. Therefore, in the process of melting the metal in the induction melting furnace of the utility model , the user can reduce the furnace by passing circulating cooling water into the cooling pipes. The maximum temperature that the bottom is subjected to, and after the metal is smelted, this water-passing state is maintained. At this time, the temperature of the furnace bottom will slowly drop under the action of cooling water. After the furnace bottom is completely cooled, the water flow is stopped. In this way, the utility model induction melting furnace effectively avoids the sudden cold and heat caused by the temperature

    Cracking.

    detailed description:

    The following describes the utility model induction melting furnace in detail with reference to the drawings and specific embodiments :

    As shown in FIG. 1 and FIG. 2, in this embodiment, the utility model induction melting furnace includes a furnace body assembly and a furnace bottom 14 located at the lower part of the furnace body assembly. The furnace body assembly includes a furnace mouth plate 4, a panel 6, and an upper furnace. Ring 7, support plate 1, lower furnace ring 13, magnet guide 8, induction coil 2 and a plurality of insulation rods II connected to the induction coil 2. The insulation rods II are all distributed on the outer peripheral wall of the induction coil 2, and the tops of the insulation rods II Between the hearth plate 4 and the hearth 14, the face plate 6 is connected to the upper hearth 7, and there are a plurality of support plates 1. The plurality of support plates 1 are evenly distributed along the circumference of the upper hearth 7 and the lower hearth 13. The upper end is connected to the upper hearth 7 and the lower end of the support plate 1 is connected to the lower hearth 13. The bottom of the lower hearth 13 is provided with a limit column 15 at the bottom. The furnace bottom 14 is installed in the inner cavity of the lower furnace ring 13. The furnace bottom 14 is made of a refractory material as a whole. The furnace bottom 14 is provided with a cooling pipe 12 through which cooling water can be passed. The induction coil 2 is located on the top of the furnace bottom 14 and the magnet is guided. There are multiple 8, multiple magnets 8 are located between the furnace mouth plate 4 and the furnace bottom 14 and are evenly distributed along the circumference of the induction coil 2. The magnets 8 The bolt 9 and the insulator 10 are connected to the support plate 1, the furnace mouth plate 4 is connected to the upper furnace ring 7 through the screw 5 and the cover plate 3, and the panel 6 and the bottom plate 17 are provided for inverting the furnace body component, thereby melting The hydraulic column 18 from which the metal liquid is poured out is provided with a column 19 between the panel 6 and the bottom plate 17. The bottom of the column 19 is connected to the bottom plate 17, and the top of the column 19 is hinged to the panel 6. In this specific implementation manner, the refractory material, the induction coil 2 and the magnetically permeable magnet 8 are all conventional existing technologies, so they are not described in detail here.
