The invention discloses a novel refractory material for dry quenching. The novel refractory material is prepared by mixing, pressing and calcining clinker, a stress buffer material, a binder, a surfactant, an impact-resistant material and a corrosion-resistant material. According to the novel refractory material for dry quenching, the waste alumina-magnesia-carbon brick regenerated powder is usedas clinker, so that the refractoriness and high-temperature volume stability of the whole refractory material are improved, the production cost is reduced, and the effects of resource regeneration, efficient utilization and social environment protection are fully achieved; the arranged stress buffer material can buffer stress generated by rapid cooling and rapid heating in use, so that the thermalshock stability, the high-temperature breaking strength, the wear resistance and the service life are greatly improved; the impact-resistant material is arranged, so that fused magnesite in the impact-resistant material reacts with aluminum oxide micro-powder to generate in-situ spinel, meanwhile, the expansion coefficient of the impact plate is adjusted, and oxidation of carbon is prevented by arranging silicon carbide; an anti-corrosion material is arranged to form chemical adhering slag on the surface of the material, corrosion of the material is delayed, and the service life of the material is prolonged.
