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, degassing and purifying treatment of the aluminum liquid is required. The working principle of degassing 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. However, the rotor device generates a vortex during rotation, the vortex can roll scum into melt, the vortex can be eliminated by reducing the rotation speed of the rotor device, and the degassing effect can be influenced by the slow rotation speed. Therefore, it is necessary to design a vortex-stopping degassing rotor slag-proof device to solve the above problems.
