High alumina self-flowing castable is an unshaped refractory material, added self-flowing agent, anti-explosion agent, and a certain amount of mineralizer with a high-strength and low-cement castable, the construction method is mechanically sprayed with pneumatic tools. No forming vibration is required during construction, which can reduce noise, improve the environment, and reduce labor intensity.
High alumina self-flowing castable can be used in outlet, inlet, cooler, hood of cement kilns.
