The invention discloses a
microwave coagulation forming
system of a water-soluble salt core, and belongs to the technical field of
casting. The
microwave coagulation forming
system comprises a salt core jetting unit, a salt core coagulation unit, a salt core soaking unit and a salt core
sintering unit, wherein the salt core jetting unit comprises a liquid distribution bin, a liquid jetting device,a material spreading device and an
infrared heating plate, wherein the liquid distribution bin is used for storing already-prepared jetting liquid, the material spreading device is used for laying inorganic salt
powder, the liquid jetting device is used for jetting the jetting liquid to the laid inorganic salt
powder to make the inorganic salt
powder aggregated and coagulated into a to-be-coagulated salt core, and the
infrared heating plate is used for preheating and
sizing the to-be-coagulated salt core. By means of the
microwave coagulation forming
system of the water-soluble salt core, thesalt core is subjected to
infrared heating and pre-forming, and is then subjected to inorganic
salt solution wetting, microwave coagulation and
sintering, since the wettability of an inorganic
salt solution is very high, pores filled with the pre-formed salt core can be fully wetted,
crystallization is conducted in the secondary microwave coagulation process, and the strength of the salt core isobviously improved.
