In recent years, due to the rapid development of science and technology, there is a large number of zinc alloy die castings in the market, and zinc alloy die casting manufacturers are growing. In fact, zinc alloy die casting is very difficult, one of the most difficult is the temperature control of die casting, and temperature control is one of the key factors for the success of die casting. So there is no doubt that too high or too low temperature will affect the quality of zinc alloy die casting. So, how does the melting temperature of zinc alloy affect the quality of zinc alloy die castings? 1. When the temperature is too high. The reaction between iron crucible and zinc alloy solution is accelerated, and the oxidation of iron occurs on the surface of crucible, resulting in Fe2O3 and other oxides; iron also reacts with liquid zinc to form fezn13 compound (zinc slag), which is dissolved in liquid zinc. The burning loss of aluminum and magnesium, the speed of metal oxidation, the amount of burning loss and zinc slag increase. In cast iron crucible, more iron is melted into the alloy, and the reaction between zinc and iron is accelerated at high temperature. Hard particles of Fe Al intermetallic compound will be formed, which will cause excessive wear of hammer head and gooseneck. In cast iron crucible, more iron is melted into the alloy, and the reaction between zinc and iron is accelerated at high temperature. Hard particles of Fe Al intermetallic compound will be formed, which will cause excessive wear of hammer head and gooseneck. Fuel consumption increased accordingly. The higher the temperature is, the coarser the crystal is, and the lower the mechanical properties are. 2. When the temperature is too low. The poor fluidity of the alloy is not conducive to forming, which will affect the surface quality of Shenzhen zinc alloy die casting.
The above is how the melting temperature of zinc alloy affects the quality of zinc alloy die casting, hoping to provide more or less help for you. In general, the zinc alloy die casting will be seriously affected by the temperature, so the temperature control is very important, need to control the temperature between 382 ~ 386 ℃, and then effectively improve the success rate of die casting, and ensure high quality. Finally, if you want to buy die castings or learn more about zinc alloy die casting, you must give priority to Diecasting-mould.
