Embodiment Construction

[0032] For further describing the present invention, below in conjunction with embodiment the present invention is described in more detail:

[0033] The non-vacuum induction furnace alloy adding device consists of an air blowing trolley 8, a splash guard 4, a conveying pipe 5, an upper air blowing pipe 1, a lower air blowing pipe 9, an air outlet 2, an air conveying pipe 6 and a protective gas source 7. The splash guard 4 and the conveying pipe 5 are connected by welding, and the splash guard 4 is in the shape of a hollow circular frustum or a prism. The splash guard 4 is located below the conveying pipe 5 , and the splash shield 4 and the conveying pipe 5 are welded on the blowing trolley 8 . The diameter of the splash guard 4 is designed according to the size of the furnace mouth, and the height of the splash guard 4 will help reduce the alloy drop, thereby reducing splashing. The upper air blowing pipe 1 and the lower air blowing pipe 9 are all made of circular rings by s...

Description

technical field [0001] The invention belongs to the technical field of induction furnace smelting, and in particular relates to an alloy adding device and method for improving the alloy yield of a non-vacuum induction furnace. Background technique [0002] Induction electric furnace steelmaking uses high-frequency current to pass through the coil to generate an AC magnetic field. The AC magnetic field forms an induced current in the charge, and relies on the resistance of the charge itself to convert electrical energy into heat energy, thereby heating the charge and melting the charge into molten steel. . [0003] In order to ensure the quality of steel, smelting is usually carried out in a vacuum induction furnace, and the scrap steel is put into the induction furnace, and the alloy elements are put into the alloy silo according to the prepared amount, and at the same time, the cast mold is put into the vacuum furnace together, and the vacuum is drawn. After reaching the l...
