AIR-CURRENT TRANSPORT SPRAY APPLICATION METHOD FOR UNSHAPED REFRACTORIES

WIPO Patent Application WO/2013/147080

A1

Provided is an air-current transport spray application method for an unshaped refractory capable of solving the difficulty of storing an unshaped refractory containing a set-accelerating agent and of managing storage, and preventing the degradation of properties, while maintaining a simple device structure. An air-current transport spray application method for an unshaped refractory in which, immediately before air-current transport, a powdered set-accelerating agent (21) is added to an unshaped refractory material (20) containing a fire-resistant aggregate, a fire-resistant powder, a binding agent, and a dispersing agent, and the components are mixed to make an unshaped fire-resistant composition (22). While the unshaped fire-resistant composition (22) is caused to be suspended inside a transport pipe (3) on air currents in powder form, application water is added inside the transport pipe (3), and then the composition is sprayed onto a application wall surface (23) through a spray nozzle (6).
