The invention discloses a high-performance castable. The high-performance castable contains the following ingredients in parts by ratio: 20-40 parts of high bauxite with the particle size of 0-1mm, 10-30 parts of high bauxite with the particle size of 1-3mm, 10-20 parts of high bauxite with the particle size of 3-5mm, 15-25 parts of high bauxite with the particle size of 5-8mm, 15-25 parts of silicon micropowder, 10-35 parts of heat insulation aggregate, 4-9 parts of dolomite, 2-5 parts of tartaric acid, 1-3 parts of explosion-proof fibers, 1-3 parts of metal aluminum powder, 1-3 parts of graphite powder, 5-10 parts of coal gangue, 5-15 parts of mullite brick, 5-10 parts of zircon, 3-7 parts of chromic oxide, 3-12 parts of magnesium-zirconium composite, 6-15 parts of phenol-formaldehyde resin and 25-45 parts of dense corundum. The high-performance castable has good heat-insulating property, has good slag resistance and has the advantages that the fired strength is high, the decline rate of strength along with the rise of heat treatment temperature is small, the thermal shock resistance is relatively good, the curing time is short, and the like.
