Beschreibung
Zusammenfassung:	The noise reduction device comprises a first noise reduction mechanism and a second noise reduction mechanism, the first noise reduction mechanism comprises a sound insulation box, sound insulation cotton adheres to the inner surface of the sound insulation box, a sound insulation plate adheres to the surface, away from the sound insulation box, of the sound insulation cotton, the second noise reduction mechanism comprises a supporting plate, and elastic telescopic mechanisms are installed at the four corners of the bottom of the supporting plate; according to the utility model, firstly, the soundproof box is arranged to enclose the demoulding equipment of the ingot casting line, so that noise generated by demoulding of an ingot in the demoulding equipment is reduced in the transmission process, and secondly, the second noise reduction mechanism is arranged on the conveying equipment below the falling position of the ingot; and the second noise reduction mechanism is attached to the bottom of the roller conve
