A kind of liquid aluminum slag removal method

Abstract

The invention discloses a molten aluminum slagging-off method. Rotating slagging-off head devices are placed on the molten aluminum level, slagging-off work begins to be operated, a worker operates aslagging-off operation rod to enable a slagging-off work face formed by the three rotating slagging-off head devices to move back and forth on the molten aluminum face, in the rotating process of a rotating slagging-off head, an arc slag filter plate continuously collects dross floating on the molten aluminum level and suspension slag below the molten aluminum level on the inner side face of the arc slag filter plate, when the arc slag filter plate is in the vertical state or tends to be in the vertical state, slag slides towards the direction of a rotating cylinder from the inner side face ofthe arc slag filter plate to enter a rotating cylinder slag inlet, when the rotating cylinder slag inlet is aligned with a slag inlet formed in the upper portion of a rotating slagging-off connectingcylinder, slag can enter the rotating slagging-off connecting cylinder to be collected, when no dross exists, a slagging-off motor is shut down, the rotating slagging-off heat devices leave the molten aluminum level, the slagging-off motor is started for reverse rotation, a lifting transmission shaft drives a lifting cylinder to rise, and when it is observed that the rotating slagging-off head devices reversely rotate, folding of the rotating slagging-off head devices is finished.

Description

technical field [0001] The invention relates to the technical field of metal smelting and industrial kiln equipment, in particular to a method for removing slag from molten aluminum. Background technique [0002] In aluminum manufacturing and processing, the melting of aluminum ingots or scrap aluminum blocks into molten aluminum is carried out under high temperature conditions in large box-type melting furnaces, because unmelted aluminum ingots or scrap aluminum blocks are usually of relatively high purity. Low, containing more impurities. After the aluminum ingot or scrap aluminum block is melted into molten aluminum, during the refining process, some impurities will be deposited in the melting furnace, and some scum will float on the surface of the molten aluminum, so the molten aluminum needs to be Slag removal and purification treatment, otherwise floating will seriously affect the quality of castings. [0003] Therefore, these melted scum must be cleaned up in the fur...
