Description

Technical Field

[0001] The utility model belongs to the technical field of ferrosilicon furnaces, and in particular relates to an ingot mold car structure used for pouring ferrosilicon water. Background Art

[0002] Under normal circumstances, after the molten iron ladle receives the ferrosilicon liquid, it is pulled out to the casting workshop by a ferrosilicon ladle car, and the molten iron ladle is lifted by a metallurgical crane to cast ingot molds.

[0032] Working principle: After the molten iron is received in the ladle 1, the exhaust fan 16 is turned on to collect the smoke from the upper end of the ladle 1 into the smoke collecting box 14 through the smoke collecting hood 2 and the duct 15 in turn, and the servo motor 26 is started to rotate the driving screw 27, and the threaded hole 25 is matched to make the sliding plate 24 drive the ingot mold 20 to move horizontally. When the ingot mold 20 moves horizontally to the bottom of the ladle 1, the driving motor 3 is started, and the output shaft of the driving motor 3 drives the rotating shaft 4 to rotate, so that the ladle 1 is tilted. When the angle of the ladle mouth of the ladle 1 changes, the smoke collecting hood 2 is pulled by the elastic rope 12, and the rolling ring 11 Under the rolling effect, the smoke hood 2 is always located above the mouth of the molten iron ladle 1, thereby ensuring the continuous collection effect of the smoke by the smoke hood 2 on the smoke, wherein the elastic force of the elastic rope 12 is smaller than the sum of the friction between the outer wall of the rolling ring 11 and the strip plate 7, the friction between the bottom surface of the first-level limiting plate 17 and the strip plate 7, and the friction between the second-level limiting plate 18 and the strip plate 7, so that the sliding of the smoke hood 2 precedes the expansion and contraction of the elastic rope 12. When the smoke hood 2 is located above the mouth of the molten iron ladle 1, the elastic rope 12 will expand and contract, thereby adapting to the change in the distance between the mouth of the molten iron ladle 1 and the smoke hood 2.
