The surface of the aluminum material has an uneven thickness of the oxide film, sometimes also absorbs water, is mixed with sand, sticky with oil stains, and painted with paint. When melting, the aluminum material is further oxidized in a high-temperature environment, the thickness of the oxide film increases, and it reacts with moisture to […]
Flux degassing is a melt treatment process used in aluminum casting to remove dissolved hydrogen and non-metallic inclusions from molten aluminum alloys. It works by combining chemical fluxing with inert gas purging: a specially formulated flux powder — typically composed of salts containing chlorine and fluorine — is injected into the melt alongside a carrier […]
Aluminum alloy smelting is one of the most important process links for the production of high-quality casting rods. Flux refining process for aluminum is an important process in aluminum alloy smelting. The main components of fluxes currently on the market are chlorides and fluorides. If the process is not properly controlled, slag, pores, coarse grains, […]
Alüminyum ve alüminyum alaşımlarının eritme sürecinde, hidrojen ve oksitlenmiş kalıntılar, alüminyum eriyiğini kirleten başlıca maddelerdir. Alüminyum, oksijenle kolayca A1202 veya sub-alümina (Al2O ve A10) oluşturur. Aynı zamanda, […]'daki toplam gazın -90%'sini oluşturan gazı (H) emmesi de çok kolaydır.
