Abstract

The invention discloses a smelting device for zinc alloy. The smelting device is composed of vacuum smelting device, a protective atmosphere furnace and a graphite crucible, wherein an air flue, a graphite stirring device and a smelting crucible are arranged in the vacuum smelting device, and the graphite crucible is provided with a mechanical stirring device. A filtering structure is fixed to thearea from the bottom to the top of the side face of the inner surface of the smelting crucible according to the structure that a dirt filtering net is arranged on a pulsator washing machine. The filtering structure is specifically composed of an aluminum oxide ceramic wedge block, an aluminum oxide ceramic outer frame, a primary coarse screen made of aluminum oxide ceramic materials and an onlinefiltering screen made of carbon fiber ceramic composite materials, wherein the outer surface of the primary coarse screen is lined with the online filtering screen. By means of the smelting device, the multi-eutectic and few-dendritic zinc alloy which is high in purity, small in large-size dendritic segregation, uniform in overall grain size refinement and original in structure can be smelted.

Description

technical field [0001] The invention relates to the technical field of zinc alloy smelting, in particular to a zinc alloy smelting equipment. Background technique [0002] Alloy smelting is an important part of the die-casting process. The smelting process is not only to obtain molten metal, but more importantly, to obtain a chemical composition that meets the requirements, so that the die-casting can obtain a good crystal structure and a metal with small gas and inclusions. liquid. During the melting process, the interaction between the metal and the gas and the interaction between the molten metal and the crucible causes the composition to change, resulting in inclusions and gettering. Moreover, in the prior art, the occupational hazard factors in the zinc alloy smelting process are more complicated, including dust, zinc oxide smoke, high temperature and other harmful gases, and the causes of these harmful substances are mostly due to the violent reaction of the slag remo...
