Method for modifying refractory molding particles and refractory molding particles obtained thereby and process for producing mold |
| abstract |
The present invention addresses the problem of modifying refractory particles, which are to be molded through use of a furan resin as a binder, and thereby attaining an effective improvement in the strength of a mold and a reduction in binder consumption. This method for modifying refractory molding particles comprises: using, as refractory particles which are to be molded through use of a furan resin as a binder, an artificial aggregate which has been produced artificially and which has an apparent porosity of 5% or less; and heat-treating the artificial aggregate in a heating atmosphere having an oxygen concentration of 15% or less at a temperature of 400 to 1500 DEG C for one or more hours. |
