Description

Technical Field

[0001] The utility model relates to the technical field of steel casting processing, in particular to a steel casting smelting device for high temperature resistant steel castings. Background Art

[0002] Steel casting is a metalworking method that involves pouring molten steel into a mold and letting it cool and solidify into the desired shape and size. During the processing, a melting device is required to melt the solid material into liquid.

[0003] In the existing smelting device, during the smelting process, the pouring nozzle is connected to the internal smelting space, and the heat in the smelting space flows out through the pouring nozzle, resulting in the need for more energy during the smelting process. At the same time, when pouring after smelting, the smelting furnace is tilted to discharge liquid through the pouring nozzle. The height of the pouring nozzle is often high, which easily causes the metal liquid to splash during pouring. Therefore, those skilled in the art provide a smelting device for cast steel for high temperature resistant steel castings to solve the problems raised in the above background technology.

[0021] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0022] It should be noted that, unless otherwise clearly stipulated and limited, the terms "installed", "provided with", "sleeved / connected", "connected", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two components.

[0023] See also Figures 1 to 4 In this embodiment, a smelting device for cast steel for high temperature resistant steel castings is provided, comprising a base 1, a support frame 2 is fixedly connected to the top of the base 1, a smelting furnace 3 is rotatably connected between the support frames 2, a pouring nozzle 34 is fixedly connected to the top of the smelting furnace 3, a baffle 35 is inserted into the pouring nozzle 34, a connecting plate 36 is fixedly connected to one end of the baffle 35, and a spring 37 is provided between the connecting plate 36 and the pouring nozzle 34;

[0024] A placement seat 5 is fixedly connected to one side of the support frame 2, a moving seat 51 is slidably connected to the placement seat 5, a push plate 52 is fixedly connected to one side of the moving seat 51, and a driving device is installed between the placement seat 5 and the moving seat 51.

[0025] When in use, a baffle 35 is provided inside the pouring nozzle 34, so that the furnace body can be closed by the baffle 35 to prevent heat dissipation. At the same time, the baffle 35 can be closed when the smelting furnace rotates, so that the pouring nozzle 34 will not be opened for pouring until it drops to the bottom, thereby reducing the distance between the pouring nozzle 34 and the mold to prevent the melted liquid from splashing out. At the same time, the baffle 35 stretches the spring 37 after opening. When the baffle 35 loses the driving force, the spring 37 recovers under its own elasticity, and the spring 37 pulls the baffle 35 to return to its original position to continue to close the pouring nozzle 34.

[0026] By designing a movable seat 51, the mold required for pouring can be moved to the bottom of the pouring nozzle 34 through the movable seat 51, and the connecting plate 36 is pushed by the push plate 52 on one side of the movable seat 51 to open the pouring nozzle 34, thereby improving the convenience during pouring. A limit device can be installed on the movable seat 51 to ensure that the mold remains stable during the movement process, or a cooling device can be installed on the movable seat 51 to improve the efficiency of solidification inside the mold.

[0027] In further embodiments, see Figure 2The smelting furnace 3 includes a heat-insulating shell 31, a smelting liner 32 is arranged inside the heat-insulating shell 31, and a heating coil 33 is arranged between the heat-insulating shell 31 and the smelting liner 32. The temperature generated when the smelting furnace 3 is working is preserved by the heat-insulating shell 31, so as to reduce heat dissipation and energy consumption. The solid material inside the smelting liner 32 is heated by electricity through the heating coil 33, and the heating is performed by the principle of induction heating (induction heating is to generate electric current inside the heated material by electromagnetic induction, and the energy of these eddy currents is relied on to achieve the purpose of heating).

[0028] In further embodiments, see Figure 2 One end of the pouring nozzle 34 is connected to the inside of the smelting liner 32, and the other end of the pouring nozzle 34 passes through the heat-insulating shell 31 and is located outside the smelting furnace 3. The liquid inside the smelting liner 32 is led out through the pouring nozzle 34.

[0029] In further embodiments, see Figure 1 , bearings are installed on both sides of the support frame 2, connecting rods are fixedly connected at both ends of the smelting furnace 3, the connecting rods are inserted into the bearings, and a driving motor 4 is installed on one side of the support frame 2, and the driving motor 4 is connected to the connecting rod. The weight of the smelting furnace 3 is borne by the bearings, so that the smelting furnace 3 can rotate smoothly, and the connecting rod is driven to rotate by starting the driving motor 4, and the connecting rod drives the smelting furnace 3 to rotate for pouring. When the driving motor 4 is connected to the connecting rod, it can be connected to the connecting rod after being decelerated by the reduction box, or connected to a gear with a larger diameter through the connecting rod, and the driving motor 4 is connected to a gear with a smaller diameter, and is connected to the connecting rod after being decelerated by the meshing of the large and small gears.

[0030] In a further embodiment, the driving device is a telescopic rod, which is transversely fixedly installed inside the placement seat 5, and one end of the telescopic rod is fixedly connected to the bottom of the moving seat 51. The moving seat 51 can be pushed close to the pouring position by extending the telescopic rod, and the moving seat 51 can be moved away from the pouring position by shortening the telescopic rod. The mold is placed on the moving seat 51 to drive the mold to move together. It should be noted that the casting port of the mold needs to be close to the edge of the mold.

[0031] In further embodiments, see Figure 4 The push plate 52 is vertically arranged, and the upper end height of the push plate 52 is higher than the lowest height of the connecting plate 36. When the push plate 52 moves with the moving seat 51, it can contact the connecting plate 36, so that the connecting plate 36 can be pushed to move by the push plate 52. By controlling the distance that the push plate 52 pushes the connecting plate 36 to move, the degree of opening of the baffle 52 can be controlled, so that the rate at which the liquid flows out of the pouring nozzle 34 can be regulated.

[0032] In a further embodiment, the smelting liner 32, the pouring nozzle 34, and the baffle 35 are all made of high temperature resistant materials. The smelting liner 32, the pouring nozzle 34, and the baffle 35 are made of refractory bricks, so that they can withstand the temperature of the liquefied metal during operation.
