The invention discloses a metal ceramic combination sintering free low carbon sliding plate brick and a preparation method thereof. The sliding plate brick comprises the following components according to weight percentage: 50%-60% of sintered plate shape alundum, 10%-25% of electric melting akerite, 5%-15% of electric melting mullite, 1%-3% of soot carbon, 3%-8% of Alpha- aluminum oxide micropowder, 5%-10% of silicon carbide, 2%-5% of metallic silicon powder,1%-5% of metallic aluminium powder, 0.5%-1% of boron carbide, 1%-3% of aluminum-silicon alloy powder, and 0.5%-2% of metallic aluminium fiber. In the invention, the product has low carbon, high thermal state strength, thermal shock resistance and good oxidation resistance, hole reaming is uniform, galling is less and the crack is verysmall; the process of the invention is characterized in that drying is carried out at a low temperature, the production cycle is shortened from 30 days originally to 7 days, the natural gas consumption is reduced to 2.5% of original technology, and the sintering free low carbon sliding plate brick is indeed belongs to the environmental protective and energy-saving and environmental material resistance product.
