  • Process for applying low-cement castable refractory material
    Patent number: 6022593
    Abstract: A method for placing a thixotropic low-cement castable refractory material without the necessity for forms. A low-cement castable material is mixed with a measured amount of water, then is pumped hydraulically through a hose to a nozzle assembly. Compressed air and a cement setting agent are added to the mixture at the nozzle. The addition of the setting agent at the nozzle overcomes the thixotropic nature of the low-cement castable, so that it will immediately "set" in position when sprayed onto a surface, including vertical and overhead surfaces.
