HIGH PRESSURE/VOLUME PROCESS FOR WET SHOTCRETING A REFRACTORY CASTABLE |
摘要 |
A method of applying a refractory castable onto a surface of a refractory structure, comprising the steps of: a) preparing a thoroughly mixed wet castable for application onto a surface of a refractory structure; b) conveying the wet-mixed refractory castable at a set rate under pressure through a delivery hose having a predetermined cross-sectional area to a dispensing device (10) having an air inlet and a dispensing nozzle (60); c) introducing air under pressure into the dispensing device, wherein the air pressure ranges from about 20 psi to about 80 psi and wherein the air has a velocity of about 177 ft/s at 20 psi and an air velocity of about 484 ft/s a t 80 psi and wherein the velocity increases by about 5 ft/s for every unit increase in the pressure.
