Liquidity Liquidity refers to the ability of the alloy die-casting mold of a liquid filling. Liquidity determines the size of the complex casting alloy whether casting. Liquidity eutectic aluminum alloy best. Many factors affect the liquidity, mainly components, the presence of metal oxides, metal compounds and other pollutants and solid particles temperature alloy liquid, but the fundamental factors external pouring temperature and pouring pressure (commonly known as the casting head) level. Actual production, recycling of used engine in the case of alloys have been identified, in addition to strengthening the melting process (refining and slag), but also the need to improve the process of casting (sand mold permeability, metal mold and exhaust temperature) acquisition of waste engine, and without prejudice to the premise of improving the quality of castings pouring temperature, to ensure the flow of the alloy. Aluminum aluminum and aluminum alloys processed into a shaped material referred to aluminum, including sheet, strip, foil, pipe, bar, wire, profiles and the like. Aluminum casting (ZL) by major elemental silicon components other than aluminum, copper, magnesium, zinc divided into four categories, code coding respectively 100,200,300,400. In order to obtain a variety of shapes and sizes of high quality precision castings waste engine, an aluminum alloy for casting generally have the following characteristics. (1) is filled with good flowability slot slit portion (2) has a lower melting point than the metal, but a great portion of the case to meet the requirements of good (3) thermal conductivity, heat of the molten aluminum to the mold to quickly transfer When casting cycle is short (4) Melt hydrogen and other harmful gases can be effectively controlled (5) by aluminum casting process, no heat brittle cracking and tearing tendency good (6) chemical stability, Strong erosion resistance (7) is not easy to produce surface defects waste engine, casting surface with good surface finish and shiny, and easy to carry out surface treatment (8) Good cast aluminum alloy processing performance, can die, die, green sand and dry sand mold, lost wax casting plaster casting mold production, can also be vacuum casting, low pressure and high pressure casting, squeeze casting, semi-solid casting, centrifugal casting, molding method, the production of different purposes, a variety of different specifications, different performance castings.
