Embodiment Construction
[0018] The present invention will be further elaborated below with reference to the accompanying drawings.
[0019] see figure 1 , in this embodiment, the method for preparing semi-solid slurry in the composite field is based on the SEED high-solid phase pulping unit and the GISS low-solid phase pulping unit. The following uses casting aluminum 357 as an example, and it includes the following steps:
[0020] In the first step S100, start the SEED high-solid phase pulping unit to start pulping;
[0021] In the second step S200, at the initial pulping stage of the SEED high-solids pulping unit, start the GISS low-solids pulping unit, so that the graphite tube of the GISS low-solids pulping unit is inserted into the SEED crucible;
[0022] In the third step S300, when the temperature of the superheated aluminum liquid for pulping begins to drop into the semi-solid range, stop the GISS low-solid phase pulping unit;
[0023] In the fourth step S400, keep rotating and shaking the ...

The invention discloses a method of semisolid slurry preparation using a compound field. The method of semisolid slurry preparation using the compound field is based on an SEED high solid phase slurrying unit and a GISS low solid phase slurrying unit, and comprises the following steps that 1, the SEED high solid phase slurrying unit is started, and slurrying is started; 2, in the initial stage ofslurrying of the SEED high solid phase slurrying unit, the GISS low solid phase slurrying unit is started, a graphite pipe of the GISS low solid phase slurrying unit is inserted into an SEED crucible;3, the temperature of an overheating aluminum liquid in slurrying starts to fall into the semisolid zone range, and the GISS low solid phase slurrying unit is stopped; and 4, the crucible of the SEEDhigh solid phase slurrying unit is kept to be rotated and shaken until the required solid fraction is achieved, and slurrying is completed. According to the method of semisolid slurry preparation using the compound field, on the basis of two present independent semisolid slurrying preparation modes, the advantages of the two slurrying mode are combined, the two technologies are overlaid, a slurrytechnology of front-back 'composition' is formed at the same time, the efficiency of SEED single method slurry preparation is improved, and meanwhile the efficiency of high solid phase semisolid state pressure casting is also improved.
Description
technical field [0001] The invention relates to the technical field of semi-solid slurry preparation, in particular to a method for preparing semi-solid slurry in a composite field. Background technique [0002] Semi-solid: Semi-solid molding technology originated from a series of research work done by Professor M.C.Flemings and his students at the Massachusetts Institute of Technology in the late 1960s and early 1970s. Semi-solid mechanism: the primary phase must be spherical, and the outer layer wraps the eutectic phase. When heated to the semi-solid temperature range, the primary phase remains solid while the eutectic phase begins to melt. Therefore, in the semi-solid casting temperature range, the microstructure of the semi-solid slurry is like tiny solid balls suspended in the liquid. SEED: Swirled Enthalpy Equilibration Device Rotating enthalpy balance to prepare high-solid-phase semi-solid slurry equipment, also refers to its process, the initials are SEED; GISS: Ga...
