Abstract: The invention relates to the field of aluminum wheel casting molds, and more particularly relates to a closed-loop control method and system for a mold temperature in a wheel casting process. The control method includes: step 1, acquiring data, that is, acquiring a plurality of mold position temperatures, and cooling pipeline opening and closing signals in a target wheel casting process according to a fixed frequency; step 2, storing, based on acquired mold opening and closing signals of casting equipment, the acquired data in a database in the form of a unique ID according to a single wheel casting process; step 3, calculating new process parameters based on the acquired plurality of position temperatures and time; and step 4, integrating the calculated process parameters, and issuing the process parameters to a PLC of a casting equipment to perform new casting.

Abstract: A method for removing dust from flue gas using an emulsion liquid membrane, including: a) dissolving a surfactant into a membrane solvent to yield a membrane-forming liquid; stirring and injecting an internal phase liquid into the membrane-forming liquid to yield an emulsion; b) stirring and adding the emulsion to an external phase liquid to disperse the emulsion into the external phase liquid to yield an emulsion liquid membrane; c) allowing the emulsion liquid membrane to contact with a flue gas for removing dust; d) separating a dust-loaded emulsion, and demulsifying the dust-loaded emulsion under an electrostatic field to release the dust from the membrane-forming liquid; recycling the membrane-forming liquid to a); and e) allowing the dust released from the demulsification to precipitate in the form of a slurry and discharging the slurry.
