Description

Electric furnace construction system and method thereof The present invention relates to an induction path shaft system and a method thereof, and more specifically, to an apparatus and method for filling and compacting a shaft material into the inner wall between the induction path and the former. Generally, an induction furnace is a furnace that produces a molten metal by placing a metal object to be heated inside and heating and melting the object through a high-frequency current. The induction furnace is equipped with a crucible made of refractory material inside the main body, and the metal placed inside the crucible is melted by resistance heating caused by an induction current generated by flowing a high-frequency current through the coil surrounding the crucible and the molten steel produced through this is discharged from the induction furnace and transferred to a subsequent process such as rolling or forging to be produced as a product. Since the inner wall of the crucible in the induction furnace is damaged by erosion caused by the high-temperature molten steel while the metal is melting inside, a refractory wall is formed to surround the inner surface and bottom surface of the crucible to protect the inner wall. The above-mentioned refractory wall is formed by stacking refractory bricks, but there was a problem in that the work of stacking refractory bricks to a uniform thickness on the inner surface and bottom surface of the crucible was difficult and took a long time. In addition, there was the inconvenience of having to manufacture refractory bricks of various shapes to lay refractory walls on the inner wall of the crucible. Recently, refractory walls are being formed by injecting refractory material into the inner wall of a crucible. For example, the following prior art document, Korean Patent Publication No. 10-2004-0057707, 'Method for repairing wall refractory material in an electric furnace with an eccentric furnace tapping method,' involves injecting dolomite into the electric furnace slag and spraying it onto the wall refractory bricks, which can result in a complex and cumbersome structure. As another example, Korean Registered Patent Publication No. 10-1377225, 'Air Removal and Compaction Device for Irregular Refractory Materials in Electric Furnace,' comprises a process of removing air contained in the refractory material using a vibrator at the bottom of the furnace body of the electric furnace, but the aforementioned problems may occur due to the complexity of its configuration.

FIG. 4 is a schematic diagram illustrating the process of introducing a shaft material for lateral compaction of an induction shaft system according to the present invention. FIG. 5 is a schematic diagram illustrating a state in which a lateral vibration unit is lowered for lateral compaction of an induction path shaft system according to the present invention.
