Gas purging plug

The invention concerns a procedure for manufacturing fireproof ceramic molded parts, particularly of high alumina content based materials.

Procedure for manufacturing of fireproof ceramic molded parts

A process for producing refractory, carbon-bonded ceramic moldings includes spraying a low-viscosity organic containing carbon containing binder onto a coarse fraction of a refractory component, the coarse fraction having a particle size larger then 0.5 mm while maintaining the coarse refractory fraction having a particle size smaller then 0.5 mm onto the coated granules, pressing the granules thus produced into moldings, and subsequently curing the organic binder in the moldings, and tempering or firing the moldings.
