Sialon-bonded corundum composite pre-cast refractory member containing metal plastic phase
The invention discloses a Sialon-bonded corundum composite pre-cast refractory member containing a metal plastic phase. The Sialon-bonded corundum composite pre-cast refractory member is prepared by additionally adding a dispersing agent and water or silica sol into raw materials of corundum aggregate, corundum fine powder, SiC fine powder, Si powder, ferro-silicon alloy powder, Al2O3 micro powder, pure calcium aluminate cement, hydrated alumina and SiO2 micro powder, forming by a vibration casting method and then carrying out in situ nitridation reaction. According to the Sialon-bonded corundum composite pre-cast refractory member disclosed by the invention, a Fe-Sialon-corundum composite refractory with low production cost, good thermal shock stability, good toughness and the metal plastic phase is prepared by introducing quantitative ferro-silicon alloy powder and using optimized combination of the raw materials, reasonable particle size distribution and simple vibration casting method.
