Co-molding process for producing refractory materials without firing or coking the refractory

摘要

The present invention is directed to a co-molding process for producing co-molded, chemical bonded, canned refractory articles which eliminates the costly and problematic firing or sintering steps and which eliminates the time consuming separate canning and sizing of the refractory articles as required by conventional methods. The co-molding process of the present invention comprises the steps of: (a) mixing a refractory aggregate with a chemical binder to form a pressable refractory composition; (b) placing a metal can into a press cavity die; (c) charging said refractory composition into said metal can and press cavity die; (d) subjecting said refractory composition to high pressures while in said press cavity die to shape and size said refractory article; and (e) drying said refractory article at temperatures sufficient to cure said chemical binder.
