More Information
Summary:The invention relates to a semi-silicon high-temperature foaming heat-insulating refractory material and a preparation method thereof, and relates to the technical field of heat-insulating refractory materials. The preparation method mainly comprises the following steps: mixing 26-54 wt% of low-aluminum aluminum-silicon natural raw materials, 40-65.5 wt% of silica, 0.5-4 wt% of kyanite, 0.2-0.5 wt% of a high-temperature foaming agent and 4 wt% of a soft clay binding agent according to the mass percentage to obtain a mixed raw material; grinding the mixed raw materials into 325 meshes by a wet method, dehydrating and granulating in a drying tower, and forming under the pressure of 100-120MPa to obtain a green body; and finally, putting the green body into a high-temperature furnace, preserving heat at 1500-1580 DEG C for 1-2 hours, calcining, cooling and discharging to obtain the semi-silicon high-temperature foaming heat-insulating refractory material. The semi-silicon high-temperature foaming heat-insulating
