Abstract
A slow setting resin-bonded taphole mix consisting essentially of a uniform admixture of a refractory grog and a bonding composition consisting essentially of a low volatile high softening point phenolic resin, a high boiling point for said resin, and a clay, and the method of using said mix to seal tapholes.
Claims9
A slow setting resin-bonded taphole mix consisting essentially of substantially uniform admixture of a refractory grog and a bonding composition consisting essentially of a low volatile high softening point phenolic resin, a solvent having a boiling point above about 550.degree. F. for said resin, and a clay.
A slow setting resin-bonded taphole mix consisting essentially of a substantially uniform admixture of:
- (a) a refractory grog consisting essentially of alumina-silica calcines, fused alumina, silicon carbide, and graphite;
- (b) a bonding composition consisting essentially of a powdered phenolic novolac resin having a softening point above about 220.degree. F., triethylene glycol, and ball clay;
- and
- (c) there being present in said mix for each 100 percent by weight of said grog and clay from about 6 to 8% by weight of said resin and about 8 to 11% by weight of said triethylene glycol.
