description The invention provides a fireproof material preparation method which comprises the following steps of heating steel slag to obtain liquid steel slag; carrying out air quenching on the steel slag, andblowing the falling liquid steel slag to obtain granular steel slag; cooling the steel slag; and screening the steel slag. A fireproof material preparation device comprises a liquid storage tank; a blowing part positioned below the liquid storage tank; a cooling part arranged in the blowing direction; and a screening part communicated with the cooling part; The problem that common sand is difficult to place for a long time when being used as fireproof sand is solved. According to the fireproof material preparation method and device provided by the invention, the preparation method is convenient to operate, a fireproof material with excellent performance is obtained, and the defects that common fireproof sand is not easy to store for a long time, is easy to harden, and needs to be replacedand supplemented regularly
