Semi-solid electromagnetic stirring product introduction

                  Equipment composition:             1)Electric control cabinet: mainly to complete the frequency conversion power, temperature control, conventional electric control, etc.             2)Water cooling system: mainly to complete the induction coil forced cooling function.             3)Stirring system: make up with iron core and induction coil             4)Heating system: adopted radiation heating or resistive heating, and the system adopts closed-loop control, PID set the regulating function, maximum temperature 1000°C, temperature difference <3°C.             5)Furnace body: The furnace according to the production process design, composition by SIC crucible, heat preservation and insulation layer, stainless steel body, into the aluminum mouth and out of the mouth can according to production needs to be set.              6)Induction coil: induction coil electrical parameter design according to production process design, using forced water cooling, the stirring frequency, stirring intensity can adjust at will.                 Operating principle             Electromagnetic stirring method using the electromagnetic induction in half a liquid metal solidification of the induced current, induced current under the action of magnetic field makes the metal solid liquid slurry agitation fiercely, make traditional dendritic structure into non dendritic mixing organization.                 Since 1971, the United States at the Massachusetts institute of technology D.B.S pencer and M.C.F lemings invented a stirring casting (stir cast) new process, with twin barrels of mechanical mixing method prepared for srr15 % pb rheological slurry, semisolid metal (SSM) casting technology has experienced more than 20 years of research and development. The alloy of stirring casting preparation commonly referred to as non-dendritic structure alloy or partially solidified casting alloys. Because of adopting the technology of the product has the characteristics of high quality, high performance and high alloying, So it is of strong vitality. In addition to the application of military equipment, began to focus on the key components for the automotive, such as, used for automobile wheel hub, can improve performance, reduce weight, reduce scrap rate. Since then, gradually been used in other areas, produce of high-performance and near net shape parts. Semi-solid metal casting molding machinery also launched. Now, has been developed to produce from 600 tons to 2000 tons semi-solid casting die casting machine, forming a weight can reach more than 7 kg. At present, in the United States and Europe, the process technology are more widely application. Semi-solid metal casting process is considered to be one of the most promising preparative technique of the near net shape and new material preparation in 21st century.                       Range of application             a Aluminum, magnesium alloy experiments stirring             b Semi-solid forming studding             c course of crystallization experimental study             d die-cast formation             e Foam metal forming             f Metal refining mixing
