Turbulence or agitation of the melt and increased holding temperature significantly increase the rate of hydrogen solution, oxidation, and transient element loss. The mechanical properties of aluminum alloys depend on casting soundness, which is strongly influenced by hydrogen porosity and entrained nonmetallic inclusions. The aluminum foundry needs to degas and filter inclusions by Online Degassing […]
During smelting, aluminum melts are purified from dissolved metal impurities (sodium, magnesium, iron and zinc), suspended oxide (non-metallic) inclusions and dissolved hydrogen. In order to purify from dissolved metal impurities, degassing methods in casting, treatment with fluxes, and filtering is important. For these purposes, various methods of purging the melts with inert and active gases, […]
With the development of the automotive industry, more and more aluminum alloy castings are used, and the requirements for casting are becoming higher and higher. In addition to ensuring the chemical composition, mechanical properties, and dimensional accuracy. Aluminum alloy castings are not allowed to have casting defects, such as pores and slag holes. Liquid aluminum […]
The Aluminum Alloy Melting is an important part of the aluminium die casting process. Aluminum alloys are commonly smelted in crucible furnaces or induction furnaces. The main task of smelting is to improve the purity and metamorphic effect of the molten aluminum. Aluminium Die Casting Process The aluminium die casting process mainly includes refining and […]
