Embodiment Construction

[0019] As shown in the figure, the non-ferrous metal liquid purification and stirring device consists of a bracket (8), a rolling wheel (5) located under the bracket (8), and a handle (10) at the end of the bracket (8). On the bracket (8) A degassing pipe (2) is provided. The end of the degassing pipe (2) is connected with a graphite rod (1) with vent holes. A three-stage heating device is provided on the degassing pipe (2). The number of heating devices can be adjusted according to The setting value of the intake air temperature or the power of the heating device is appropriately increased or decreased, usually one to three levels. The degassing pipe (2) is connected in series with the ventilation control valve group (6), and the ventilation control valve group (6) is composed of two to five vent valves connected in parallel, and there are five in this embodiment. The air inlet (4) of the ventilation control valve group is communicated with the inert gas conduit, and a flow me...

Abstract

The invention discloses a device for purifying and stirring non-ferrous metal liquid, which comprises a support, a rolling wheel arranged under the support, a handle at the tail end of the support and the like, wherein a degassing pipe is arranged on the support; the tail end of the degassing pipe is connected with a graphite rod which is provided with an air vent; a multi-level heating device isarranged on the degassing pipe; the degassing pipe is communicated with a vent control valve assembly in series; the vent control valve assembly comprises a plurality of vent valves in parallel mutually; an air inlet of the vent control valve assembly is communicated with an inert gas conduit; and a flowmeter, a circuit control device for controlling the ventilation volume and the heating volume and a control panel are arranged at appropriate positions of the support. Compared with the products in the prior art, the cast molding non-ferrous metal ingot which is refined by utilizing the deviceprovided by the invention has the advantages that: the hydrogen content of alloy is obviously reduced and can reach to 0.10cc / 100g aluminium; the rate of removing impurities in the alloy, that is an impurity removing rate can be enhanced by 10% compared with that of the products processed by using the prior art; and as the hydrogen content and the impurity are reduced, the comprehensive property of the alloy can be enhanced by 10% compared with the prior art.

Description

Technical field [0001] The invention relates to a non-ferrous metal liquid purification and stirring device for purifying and stirring the non-ferrous metal liquid in a furnace before casting. Background technique [0002] At present, the smelting and product processing of light metals-mainly the smelting and processing of aluminum or aluminum alloy products. The process is roughly like this: the raw materials are first smelted and melted, and then alloyed. Inert gas is introduced into the furnace to carry out the purification and stirring process of hydrogen removal and inclusion removal in the furnace. After standing, the density of the aluminum alloy liquid and the hydrogen content in the alloy liquid are tested and the indicators can be cast out of the furnace. The refining of liquid metal is an extremely important process. The main task of this process is to remove the hydrogen in the alloy liquid, and at the same time, it can remove part of the inclusions in the alloy. It c...
