Description
Technical Field
[0001] The present application relates to the field of casting technology, and in particular to a bidirectional tilting pouring electric furnace. Background Art
[0002] In the process of casting metal parts, pouring is one of the key steps in the casting process, which refers to pouring molten metal or other materials into a pre-prepared mold to form parts of the desired shape. If the temperature during the pouring process is not properly controlled, the metal liquid will solidify prematurely in the mold, causing defects inside the casting, affecting its mechanical properties and service life. Therefore, precise control of pouring temperature and time is crucial to ensure the quality of castings.
[0003] In the traditional pouring method, workers need to manually operate the ladle to pour the molten metal into the mold, and then the metal liquid cools and solidifies to form. This process requires a high degree of precision and skill, is labor-intensive, and there are certain safety hazards for workers working in a high-temperature environment. In order to improve the quality of castings and reduce the labor intensity of workers, with the advancement of technology, mechanized and automated equipment has gradually been introduced into the industry, such as bottom pouring pouring machines. Generally, this type of pouring machine uses a cylinder to tilt forward to pour molten iron into the iron inlet, and uses a cylinder instead of manpower to tip over. However, production lines often rely on this single method for pouring, and the production tasks are heavy. The temperature of the molten iron in the pouring furnace will gradually decrease as the pouring time continues. Some of the molten iron cannot continue to be used due to insufficient temperature and can only be poured out. This not only causes a waste of resources, but also affects production efficiency and cannot fully meet the needs of modern production. Summary of the invention

[0047] In order to better understand the technical solution of the present application, a specific example is provided below for illustration. The details listed in the example are mainly for ease of understanding and are not intended to limit the scope of protection of the present application.
[0048] Before pouring, the pouring furnace cover oil cylinder 8 opens the pouring furnace cover 8 vertically, and the plunger system controls the stopper rod to close the second molten iron inlet 7 downward to prevent molten iron from leaking, and the molten iron is poured into the pouring furnace 2. When the molten iron level in the pouring furnace 2 reaches the set position, the pouring furnace cover oil cylinder 8 restores the pouring furnace cover 8 to a horizontal position, and the pouring furnace cover 8 is closed to keep warm. At this time, the entire pouring furnace 2 is in a horizontal state.
[0049] During the pouring operation, when the temperature of the molten iron in the pouring furnace 2 decreases over time and the remaining molten iron needs to be poured out, the forward tilting or backward tilting operation is selected according to the liquid level and temperature of the molten iron. Figure 3 As shown in FIG. 1 , if it is necessary to pour out by tilting forward, the tilting cylinder 3 is extended to tilt the pouring furnace 2 toward the first molten iron nozzle 6, and the tilting bracket 5 is tilted to 93 degrees to ensure that the molten iron is completely emptied. When the molten iron in the pouring furnace 2 is at a low level during operation and the remaining molten iron needs to be poured out by tilting backward, as shown in FIG. Figure 4 As shown, the rearward tilting cylinder 4 is retracted and the forward tilting cylinder 3 is retracted at the same time. At this time, the height of the rear side of the cylinder is lower than the height of the front side of the cylinder. The pouring furnace 2 is tilted toward the second iron water outlet 7. After the plunger is removed from the second iron water outlet 7, the molten iron can be poured out from the second iron water outlet 7.
