METHOD FOR REGENERATION OF CASTING MOLD SAND AND REGENERATION SYSTEM
Document Type and Number:
Japanese Patent JP2017074604
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method for regeneration of casting mold sands and a regeneration system for effectively separating magnetically attractable substances from casting mold sands.SOLUTION: A method for regeneration of casting mold sands includes: a step in which metal powders and metal pieces are removed from the casting mold sands S as an object, which are separated from a cast by shot-blasting, by magnetic separation of a first magnetic flux density, and magnetically attractable substances are removed by magnetic separation of a second magnetic flux density higher than the first magnetic flux density; and a step in which substances containing a carbide adhering to surfaces of the casting mold sands are removed from the casting mold sands by dry type mechanical regeneration.SELECTED DRAWING: Figure 1
