Title: The Influence of Electromagnetic Vibration on Hot Cracking Initiation of Aluminum Alloy Produced by Continuous Casting
Abstract:In the process of continuously cast ingot of aluminum alloy,the forced vibration of molten melt is produced by the simultaneous application of a stationary magnetic field and a variable magnetic field...In the process of continuously cast ingot of aluminum alloy,the forced vibration of molten melt is produced by the simultaneous application of a stationary magnetic field and a variable magnetic field.On the one hand,reduce the external factors for initiating hot cracking through improving the as-cast condition to decrease the size of unfeeding zone,to reduce the thermal stress and strain,to make allo-ying brittleness zone mainly in the state of being compressed.on the other hand,decrease the hot cracking tendency of alloys by the method of reducing the size of alloying brittleness zone,increasing the extensibility of solid/liquid phase,decreasing the quantities of eutectic compounds with low melting point and the linear contraction of effective solidifying zone.As the results of the two facts,the cracking of as-cast ingot was eliminated.Read More
