Description

Aluminum liquid purification device

Technical Field

The utility model relates to a gold control equipment field especially relates to aluminium liquid purifier.

Background

In a casting workshop, the hydrogen content and non-metallic inclusions of molten aluminum can seriously affect the quality of castings. Generally, in the condensation process, as the solubility of hydrogen is reduced, hydrogen cannot escape from a solution in time, and non-metallic inclusions cannot float to the liquid surface before entering a crystallizer in time, a series of defects such as white spots on the surface of a plate, increase of pinholes, reduction of mechanical properties of a material and the like are caused in the subsequent rolling process, and finally, the product is scrapped. Therefore, the aluminum liquid must be purified.

The working principle of the aluminum liquid purification device is as follows: by utilizing the property that the inert gas does not chemically react with the aluminum liquid at the casting temperature and is not dissolved in the aluminum melt, the inert gas is blown into the aluminum liquid through a rotor rotating at high speed in the rotor device to form a large amount of continuous fine bubbles. As the inert gas bubbles rise from the bottom of the melt chamber, hydrogen in the melt will continue to diffuse into the bubbles as the partial pressure of hydrogen in these bubbles is zero, until equilibrium is reached when the partial pressure of hydrogen in the bubbles increases to a level which is in accordance with the concentration of hydrogen in the melt. After the bubbles float out of the liquid surface, the hydrogen in the bubbles escapes into the atmosphere. In the floating process of the bubbles, when nonmetallic inclusions are encountered, the inclusions are adhered to the surfaces of the bubbles under the action of surface tension, the inclusions are removed along with the floating of the bubbles, and meanwhile, the filtering medium in the filtering cavity can further mechanically block the inclusions, so that the impurities are deposited and blocked in the filtering medium, and the aluminum liquid is purified.

At present, a vent pipe is usually inserted into a barrel filled with aluminum liquid, and inert gas is discharged from the vent pipe to purify the aluminum liquid, however, the common vent pipe jets the inert gas in one direction, only the aluminum liquid in the middle part of the aluminum liquid barrel can be purified, and the corners of the edge of the aluminum liquid barrel cannot be completely purified, so that a series of defects of white spots, increased pinholes, reduced mechanical properties of materials and the like on the edge surface of a aluminum sheet material are caused in a subsequent rolling process, and finally the product is scrapped.
