Wet-gunning method

Wet-gunning method

A low-cement, castable refractory material obtained by mixing 100 weight % of a refractory composition comprising 67-97.5 weight % of refractory aggregate having a particle size of 10 mm or less, 2-25 weight % of ultra-fine refractory powder having a particle size of 10 mu m or less and 0.5-8 weight...

Beschreibung
Zusammenfassung:A low-cement, castable refractory material obtained by mixing 100 weight % of a refractory composition comprising 67-97.5 weight % of refractory aggregate having a particle size of 10 mm or less, 2-25 weight % of ultra-fine refractory powder having a particle size of 10 mu m or less and 0.5-8 weight % of alumina cement with 0.01-1.0 weight % (outer percentage) of a dispersing agent is premixed with water by a mixer to provide a castable mixture, which is conveyed to a gunning nozzle by a pump, and gunned through the nozzle together with 0.1-1.5 weight % (outer percentage), per 100 weight % (on a solid basis) of the low-cement, castable refractory material, of an alkali silicate solution having an SiO2/R2O molar ratio of 2.0-3.3 (R2O is an alkali metal oxide) and a Baumé degree of 40 or more at 15 DEG C as a shape retention agent by means of compressed air.
