Aluminum alloy refining system

Abstract

The invention discloses an aluminum alloy refining system. The system comprises a base, wherein a refining rabbling furnace is fixedly installed at the upper end of the base; a pressure transducer is arranged at the inner top end of the refining rabbling furnace; the right side of the refining rabbling furnace is connected with a dissolving tank through an air outlet pipe; the left side of the upper end of the refining rabbling furnace is fixedly connected with a feeding port; a molten aluminum outlet pipe is fixedly connected to the left side of the bottom end of the refining rabbling furnace; a stirring device is arranged in the refining rabbling furnace; a filter sieve is arranged on the stirring device; a connecting base is arranged at the upper end of the filter sieve; and adjusting devices are arranged at the two sides of the connecting base. The invention relates to the technical field of smelting devices. According to the aluminum alloy refining system, through the arranged adjusting devices, lifting of the connecting base can be controlled, then the distance between a grinding wheel and the surface of the filter sieve is controlled, coagulums are fully ground and smashed, and the situation that blocky refining agents block outlets of screening holes of the filter sieve and cannot uniformly enter an aluminum alloy solution is prevented.

Description

technical field [0001] The invention relates to the technical field of smelting devices, in particular to an aluminum alloy refining system. Background technique [0002] Aluminum alloy has small weight, low thermal expansion coefficient, good casting performance and wear resistance. The alloy castings cast with it have high impact resistance and good high-pressure compactness, so they have been widely used in many industries. In order to prevent shrinkage and porosity of the aluminum alloy and improve the quality of the aluminum alloy, it is necessary to fill in nitrogen in the process of smelting the aluminum alloy to drive away the gas in the aluminum alloy solution, and add a refining agent to make the impurities in the aluminum alloy solution Precipitate and float to the liquid surface to remove impurities. [0003] The refining stirring furnace blows the refining agent through nitrogen and sends the refining agent to the powder refining agent inlet pipe by nitrogen pr...
